Answer 1

Hypothesis Testing for the given case: Hypothesis Test: To determine if the percentage of the students in the school who speaks languages other than English is different from 42.3%. Null Hypothesis (H0): The proportion of the students in the school who speaks languages other than English is equal to 42.3%.H0: p = 0.423. Alternate Hypothesis (Ha):The proportion of the students in the school who speaks languages other than English is not equal to 42.3%.Ha: p ≠ 0.423. Random Variable: The random variable is defined as the proportion of students in the school who speaks languages other than English. p = Proportion of students in the school who speaks languages other than English. Distribution to Use: Since the sample size (n) is greater than or equal to 30, the normal distribution can be used. Test Statistic: Using the sample data, the test statistic is calculated as shown below: z = (x - μ) / (σ / √n)where x = number of students who speak other languages at home = 38μ = proportion under the null hypothesis = 0.423σ = standard deviation = √(p(1 - p) / n) = √(0.423(1 - 0.423) / 38) = 0.0878z = (38 - 0.423(38)) / (0.0878) = 14.862P-Value:The P-Value can be calculated by finding the area under the normal distribution curve. Z = 14.862 is too high and therefore, the area in the tail region is very low. The P-value is found to be less than 0.0001. Since the P-value is much lower than the level of significance (α = 0.05), we can reject the null hypothesis.

Conclusion: Based on the hypothesis test, the proportion of students in the school who speak languages other than English is different from 42.3%.

HELP PLEASE!!!!!! Find the speed of an athlete who makes 4and3/4 laps in 3mins45 seconds on a 400m field in m/s​

Answers

Given:

An athlete who makes [tex]4\dfrac{3}{4}[/tex] laps in 3 mins 45 seconds on a 400m field.

To find:

The speed of the athlete in m/s.

Solution:

We know that,

Distance covered in 1 lap = 400 m

Distance covered in [tex]4\dfrac{3}{4}[/tex] laps = [tex]4\dfrac{3}{4}\times 400[/tex] m

                                               = [tex]\dfrac{19}{4}\times 400[/tex] m

                                               = [tex]1900[/tex] m

We know that,

1 minute = 60 seconds

3 minutes = 180 seconds

3 minutes 45 second = 180 + 45 seconds

                                   = 225 second

The speed of the athlete is:

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]Speed=\dfrac{1900}{225}[/tex]

[tex]Speed\approx 8.44[/tex]

Therefore, the speed of the athlete is about 8.44 m/s.

the scatterplot shows the number of hours that 12 people spent learning to type on a keyboard and each persons average typing speed. Based on the scatterplot, what is the best prediction of a persons average typing speed in words per min. if the person has spent 70 hours learning to type?

Answers

Answer:

85 wpm

Step-by-step explanation:

From the scatter plot, we can see the following;

At 20 hours, average typing speed = 34 wpm

At 30 hours, the average typing speed = 40 wpm

At 40 hours, the average typing speed = 51 wpm

At 50 hours, the average typing speed = 65 wpm

Average differences = ((40 - 34) + (51 - 40) + (65 - 51))/3 = 10.3

Approximating to a whole number = 10

Now, we can approximate that at 60 hours, average typing speed = 65 + 10 = 75 wpm

At 70 hours, the average typing speed = 75 + 10 = 85 wpm

Answer:

85 wpm

Answers

Answer:

Selling price of the laptop is $600.

Step-by-step explanation:

Let the sale price of the laptop = $x

Regular price of the laptop = $750

Discount on each computer = 20%

Selling price of the laptop 'x' = 750 - (20% of 750)

                                                = 750 - [tex](\frac{20}{100}\times 750)[/tex]

Step-by-step explanation:

r = number of red

g = number of green

r = g + 15 (the number of red apples is 15 more than the number of green apples)

r + g = 41

Substitute the first equation into the second and solve for a numerical value of g

(g + 15) + g = 41

2g + 15 = 41

2g = 26

g = 13

The false statement among the following statements is: |ez| = |e³|. Here, e is the Euler number, and z is a complex number. Therefore, the correct answer is option (i) |ez| = |e³|.

We know that e^(ix) = cos(x) + i sin(x)

It is also known as Euler's formula, where e is the Euler number, i is the imaginary unit, x is the angle in radians. This formula connects the trigonometric functions with the exponential function. In this question, e is the Euler number, and z is a complex number. So, ez = |ez| × e^(iθ), where θ is the angle of the complex number z from the positive real axis. In the same way, e³ = |e³| × e^(i3θ)Here, the modulus of ez is |ez|, and the modulus of e³ is |e³|. It is not necessary that both will be equal because the value of θ may differ. Hence, the false statement is |ez| = |e³|.

Answers

The set of vectors (b) (-3,0,4), (5,-1,2), (1,1,3) are linearly dependent. The other given sets of vectors in R3 are linearly independent.

Let's review the given sets of vectors in R₃ to determine which ones are linearly dependent.

(a) (4.-1,2), (-4, 10, 2).

To check if the given set is linearly dependent or not, we need to check whether there are non-zero scalars such that their linear combination is equal to

0.a(4,-1,2) + b(-4,10,2) = (0,0,0).

The system of equations can be written as;

4a - 4b = 0-1a + 10b = 00a + 2b = 0.

Clearly, a = b = 0 is the only solution.

So, the set is linearly independent.

(b) (-3,0,4), (5,-1,2), (1, 1,3)

To check if the given set is linearly dependent or not, we need to check whether there are non-zero scalars such that their linear combination is equal to

0.a(-3,0,4) + b(5,-1,2) + c(1,1,3) = (0,0,0).

The system of equations can be written as;

-3a + 5b + c = 00a - b + c = 00a + 2b + 3c = 0

Clearly, a = 2, b = 1, and c = -2 is a solution.

So, the set is linearly dependent.

(c) (8.-1.3). (4,0,1).

To check if the given set is linearly dependent or not, we need to check whether there are non-zero scalars such that their linear combination is equal to

0.a(8,-1,3) + b(4,0,1) = (0,0,0).

The system of equations can be written as;

8a + 4b = 01a + 0b = 0-3a + b = 0.

Clearly, a = b = 0 is the only solution.

So, the set is linearly independent.

(d) (-2.0, 1), (3, 2, 5), (6,-1, 1), (7,0.-2).

To check if the given set is linearly dependent or not, we need to check whether there are non-zero scalars such that their linear combination is equal to

0.a(-2,0,1) + b(3,2,5) + c(6,-1,1) + d(7,0,-2) = (0,0,0)

The system of equations can be written as;

-2a + 3b + 6c + 7d = 00a + 2b - c = 00a + 5b + c - 2d = 0

Clearly, a = b = c = d = 0 is the only solution.

So, the set is linearly independent.

Therefore, The set of vectors (b) (-3,0,4), (5,-1,2), (1,1,3) are linearly dependent. The other given sets of vectors in R₃ are linearly independent.

Answers

The integrating factor for the given differential equation is |x^2 - 1|.

To find the integrating factor for the given differential equation, we start by rearranging the equation in the form:

dy/dx + (2y)/(x^2 - 1) = (4(x + 1))/(x^2 - 1)

The integrating factor (IF) is given by the exponential of the integral of the coefficient of y, which in this case is (2/(x^2 - 1)). Therefore, the integrating factor IF is:

IF = exp ∫ (2/(x^2 - 1)) dx

To evaluate this integral, we can use a substitution. Let u = x^2 - 1, then du = 2x dx. Substituting this back into the integral, we get:

IF = exp ∫ (1/u) du = exp(ln|u|) = |u|

Since u = x^2 - 1, we have:

IF = |x^2 - 1|

Therefore, the integrating factor for the given differential equation is |x^2 - 1|.

The significance level of 0.01 indicates that we want to use a 1% level of significance to evaluate the evidence against the null hypothesis.

The null and alternative hypotheses for testing the claim that the majority of college students' cell phone bills are paid by their parents can be stated as follows:

Null hypothesis (H0): The majority of college students' cell phone bills are not paid by their parents.

Alternative hypothesis (Ha): The majority of college students' cell phone bills are paid by their parents.

In this scenario, the null hypothesis assumes that the proportion of college students whose parents pay their cell phone bills is less than 50% (not a majority), while the alternative hypothesis suggests that the proportion is greater than or equal to 50% (a majority). The significance level of 0.01 indicates that we want to use a 1% level of significance to evaluate the evidence against the null hypothesis.

a simple random sample of 800 elements generates a sample proportion p= 0.77 ( round awsners to 4 decimal places)
a) provide a 90% confidence interval for the population proportion
b) provide a 95% confidence interval for the population proportion

Answers

The 95% confidence interval for the population proportion is approximately (0.7465, 0.7935).

(a) To calculate a 90% confidence interval for the population proportion, we can use the formula:

Confidence Interval = sample proportion ± z * sqrt((sample proportion * (1 - sample proportion)) / sample size)

Given that the sample proportion is p = 0.77 and the sample size is n = 800, we need to find the critical value, z, corresponding to a 90% confidence level.

Using a standard normal distribution table or a statistical software, the critical value for a 90% confidence level is approximately 1.645.

Substituting these values into the formula, we have:

Confidence Interval = 0.77 ± 1.645 * sqrt((0.77 * (1 - 0.77)) / 800)

Calculating the confidence interval, we get:

Confidence Interval = 0.77 ± 0.0191

Therefore, the 90% confidence interval for the population proportion is approximately (0.7509, 0.7891).

(b) Similarly, to calculate a 95% confidence interval, we need to find the critical value corresponding to a 95% confidence level. The critical value is approximately 1.96 for a 95% confidence level.

Using the same formula and substituting the values, we have:

Confidence Interval = 0.77 ± 1.96 * sqrt((0.77 * (1 - 0.77)) / 800)

Calculating the confidence interval, we get:

Confidence Interval = 0.77 ± 0.0235

Which expression is evaluated first in the following statement?
if (a > b && c == d || a == 10 && b > a * b)?
a. a * b
b. b && c
c. d || a
d. a > b
e. none of the above

Answers

The expression "a > b" is evaluated before the other expressions.

How to evaluate an expression?

Follow the order of operations (PEMDAS/BODMAS). Evaluate the expression following the order of operations or the rules of precedence.

Let's break down the given statement and determine the order of evaluation for each expression:

if (a > b && c == d || a == 10 && b > a * b)

The statement consists of two logical expressions connected by the "&&" and "||" operators. To determine the order of evaluation, we need to consider operator precedence and associativity.

1. Parentheses: As there are no parentheses in the statement, we move on to the next step.

2. "&&" Operator: The "&&" operator has higher precedence than the "||" operator, so expressions connected by "&&" are evaluated before those connected by "||".

The first expression connected by "&&" is "a > b". Let's call this Expression 1.

The second expression connected by "&&" is "c == d". Let's call this Expression 2.

3. "||" Operator: The "||" operator has lower precedence than the "&&" operator.

The first expression connected by "||" is Expression 1 (a > b) && (c == d).

The second expression connected by "||" is "a == 10" && "b > a * b". Let's call this Expression 3.

Now, let's evaluate each expression in the given order:

Expression 1: a > b

Expression 2: c == d

Expression 3: a == 10 && b > a * b

Therefore, the expression evaluated first in the given statement is Expression 1: a > b.

To summarize, in the statement "if (a > b && c == d || a == 10 && b > a * b)", the expression "a > b" is evaluated first.

Answer: B

The surface area of the right cylinder is 140π cubic units or 439.60 cubic units.

Step-by-step explanation:

We have formula to find the surface area of a right cylinder.

Surface area = 2πr(h + r)

Given: r = 5 and h = 9,

Now plug in the value of r and h in the above formula, we get

Surface area = 2π.5 (9 + 5)

= 10π(14)

Surface area = 140π

The value of π = 3.14, when we plug in the value of π, we get

The surface area = 140 × 3.14

Define a relation Ron R by for a,beR (a,b) e Rif and only if a-bez Which of the following properties does have? Reflexive Symmetric Antisymmetric Transitive

Answers

In summary:

The relation R is reflexive. The relation R is not symmetric. The relation R is antisymmetric. The relation R is transitive.

 

Let's analyze the properties of the relation R:

Reflexive:

A relation R is reflexive if every element in the set is related to itself. In this case, we need to check if (a, a) belongs to R for every a in the set.

For the given relation R: (a, b) belongs to R if and only if a - b = 0.

Since a - a = 0, (a, a) satisfies the condition and is in R for every a in the set. Therefore, the relation R is reflexive.

Symmetric:

A relation R is symmetric if for every (a, b) belongs to R, (b, a) must also be in R.

For the given relation R: (a, b) belongs to R if and only if a - b = 0.

However, if a - b = 0, it does not imply that b - a = 0. Therefore, the relation R is not symmetric.

Antisymmetric:

A relation R is antisymmetric if for every distinct (a, b) belongs to R, (b, a) cannot be in R.

For the given relation R: (a, b) belongs to R if and only if a - b = 0.

Since a - b = 0 implies b - a = 0, it means that if (a, b) and (b, a) are in R, then a must be equal to b. Thus, for distinct elements a and b, it is not possible for both (a, b) and (b, a) to be in R. Therefore, the relation R is antisymmetric.

Transitive:

A relation R is transitive if for every (a, b) and (b, c) belongs to R, (a, c) must also be in R.

For the given relation R: (a, b) belongs to R if and only if a - b = 0.

If a - b = 0 and b - c = 0, it implies that a - c = 0. Therefore, if (a, b) and (b, c) are in R, then (a, c) is also in R. Thus, the relation R is transitive.

In summary:

The relation R is reflexive.

The relation R is not symmetric.

The relation R is antisymmetric.

The relation R is transitive.

This tutorial provides step-by-step instructions on how to perform an independent samples t-test in SPSS and interpret the results.

The tutorial outlines the following steps to conduct an independent samples t-test in SPSS:

Access the Analyze menu.

Select "Compare Means" and then "Independent-Samples T Test."

Drag and drop the dependent variable into the "Test Variable(s)" box and the grouping variable into the "Grouping Variable" box.

Define the groups by clicking on "Define Groups" and inputting the coded values that represent each group.

Click "Continue" and then "OK" to run the test.

The results will be displayed in the SPSS data viewer.

By following these steps, users can conduct an independent samples t-test to compare means between two groups and assess whether there is a statistically significant difference. The result provides information such as the t-value, degrees of freedom, and p-value, which is used to interpret the significance of the difference between the means of the two groups. Researchers can then make conclusions based on the statistical findings from the independent samples t-test.

A restaurant opens at 7 a.m.each day,and stays open until 2:59 a.m.the next morning Their food service employees work two four-hour shifts per day. For some workers,the two shifts are consecutive effectively one eight-hour shift),but other workers work split shifts,with a four hour gap between their shifts. All food service workers earn a base rate of $14 per hour.In addition,there is a bonus of $12 paid to each person who works on a split-shift. The restaurant has the following daily requirements: Shift Minimum Number Index Time of Day of Workers Needed 1 7 a.m.to 10:59 a.m. 15 2 11:00 a.m.to2:59p.m. 23 3 3:00 p.m.to6:59 p.m. 11 4 7:00 p.m.to 10:59 p.m. 25 5 11:00p.m.to2:59a.m. 6 Subject to meeting all its requirements for workers,the restaurant wishes to minimize its daily labour cost (regular and bonus).Formulate the model so that the $14 and the $12 are entered only once.
