Answer:

(.25)(.30) = .075 probability that both children will get the flu

The probability that both a youngster in New York and a kid in Los Angeles will get this season's virus can be determined by duplicating the singular probabilities. Consequently, the likelihood that both will get influenza is 0.075.

To find the probability of the two occasions happening, we duplicate the probabilities of every occasion. Considering that the probability of a kid in New York getting this season's virus is 0.25 (or 25%) and the probability of a youngster in Los Angeles getting influenza is 0.30 (or 30%), we multiply these probabilities: 0.25 * 0.30 = 0.075. This implies there is a 0.075 probability, or 7.5%, that both a youngster in New York and a kid in Los Angeles will get influenza.

The correct matching of the confidence level with the confidence interval for μ is as follows:

x ± 1.96 --> A. 95%

x ± 2.575 --> B. 99%

x ± 1.645 --> C. 90%

A confidence level of 95% corresponds to a critical value of 1.96. This means that if we construct a confidence interval by taking the sample mean (x) and adding or subtracting 1.96 times the standard error, we can be 95% confident that the true population mean (μ) falls within this interval.

A confidence level of 99% corresponds to a critical value of 2.575. Similarly, constructing a confidence interval using the sample mean and adding or subtracting 2.575 times the standard error will give us a wider interval within which we can be 99% confident that the true population mean falls.

A confidence level of 90% corresponds to a critical value of 1.645. Constructing a confidence interval using the sample mean and adding or subtracting 1.645 times the standard error will give us a narrower interval within which we can be 90% confident that the true population mean lies.

These critical values are based on the standard normal distribution and are chosen to achieve the desired level of confidence.

Answer:

the second, and fourth one's are triangles, and the 1st and 2nd are not

Step-by-step explanation:

We know that the angles in a triangle add up to 180 degrees. So we need to find which angles add up to 180 degrees. We have:

56+34+42=132

That means the first one can't be a measures of a triangle.

75+55+50=180

Second one is a triangle.

35+32+23=90

Third isn't a triangle

124+64+16=180

So all in all, the second, and fourth one's are triangles, and the 1st and 2nd are not

We have proved the first assertion that "If x is even and y is odd, then x + 2y is even" using direct proof. However, the second assertion "If x and y are odd, then (x + 3) + y is odd" is not true.

A.

The truth value of statement a) VX EN, x + 4 < 2 is false because there is no natural number x in the set N = {1, 2, 3, 4, 5} that satisfies the inequality x + 4 < 2.

The truth value of statement b) 3x EN, x + 2 > 5 is true because for all natural numbers x in the set N = {1, 2, 3, 4, 5}, the inequality 3x + 2 > 5 holds.

The negations of the given statements are:

Negation of a): ~ (VX EN, x + 4 < 2) which is EX EN, ~(x + 4 < 2), i.e., there exists an x in N such that x + 4 is not less than 2.

Negation of b): ~ (3x EN, x + 2 > 5) which is EX EN, ~(x + 2 > 5), i.e., there exists an x in N such that x + 2 is not greater than 5.

B.

To prove the assertion "If x is even and y is odd, then x + 2y is even" using direct proof, we assume that x is even and y is odd. We can express x as 2a (where a is an integer) and y as 2b + 1 (where b is an integer). Substituting these values into x + 2y, we get 2a + 2(2b + 1) = 2(a + 2b + 1), which is clearly an even number. Hence, x + 2y is even.

To prove the assertion "If x and y are odd, then (x + 3) + y is odd" using direct proof, we assume that x and y are odd. We can express x as 2a + 1 and y as 2b + 1. Substituting these values into (x + 3) + y, we get (2a + 1 + 3) + (2b + 1) = 2(a + b + 2), which is clearly an even number. This contradicts the assertion, and therefore, it is not true.

In summary, we have proved the first assertion that "If x is even and y is odd, then x + 2y is even" using direct proof. However, the second assertion "If x and y are odd, then (x + 3) + y is odd" is not true.

Step-by-step explanation:

You need the find the cost per bag in those weeks.

Three weeks ago, she could buy a bag for N5,700.

Three weeks after that, she could only buy half a bag for the same amount. A bag therefore costs:

= 5,700 ÷ 2/4

= N11,400

The percentage increase is:

= (11,400 - 5,700) / 5,700

The given function is y = 1/x. We need to use upper and lower sums to approximate the area of the region using the given number of subintervals (of equal width).

Given Function: y = 1/x Number of Subintervals: 6Width of Subinterval: (b-a)/n = (5-1)/6 = 4/6 = 2/3For Lower Sum, we take the minimum value of each subinterval and sum them up.

Lower Sum: ∑ i=1^n f(x_i*)Δx=∑ i=1^n f(a+iΔx)ΔxNow,

we calculate the Lower Sum: ∑ i=1^6 f(x_i*)Δx=∑ i=1^6 f(1+i(2/3))2/3=∑ i=1^6 2/(3(i+1))=0.903

For Upper Sum, we take the maximum value of each subinterval and sum them up.

Upper Sum: ∑ i=1^n f(x_i**)Δx=∑ i=1^n f(a+(i-1)Δx)ΔxNow,

we calculate the Upper Sum: ∑ i=1^6 f(x_i**)Δx=∑ i=1^6 f(1+i(2/3))2/3=∑ i=1^6 2/(3i)=1.361

Hence, the Lower Sum of the given function is 0.903 and the Upper Sum is 1.361.

The mean of the heights of Wendigos ≈ 302.523 cm, and the standard deviation ≈ 14.165 cm.

To obtain the mean and standard deviation of the heights of Wendigos, we can use the information given about the percentiles.

Let's denote the mean as μ and the standard deviation as σ.

Step 1: Finding the Z-scores

First, we need to find the Z-scores corresponding to the given percentiles.

For the lower percentile:

Z = (X - μ) / σ = -1.880

For the upper percentile:

Z = (X - μ) / σ = 1.880

Step 2: Finding the corresponding values using Z-scores

Next, we need to find the values corresponding to the Z-scores using a standard normal distribution table or a calculator.

For the lower percentile:

Z = -1.880 corresponds to a cumulative probability of 0.0359

For the upper percentile:

Z = 1.880 corresponds to a cumulative probability of 0.9601

Step 3: Calculating the values

Using the cumulative probabilities obtained, we can find the corresponding values.

For the lower percentile:

X = Z * σ + μ

273 = -1.880 * σ + μ

For the upper percentile:

X = Z * σ + μ

326.25 = 1.880 * σ + μ

Step 4: Solving the equations

We now have a system of equations with two unknowns (μ and σ).

273 = -1.880 * σ + μ   (Equation 1)

326.25 = 1.880 * σ + μ   (Equation 2)

We can solve this system of equations to find the values of μ and σ.

Subtracting Equation 1 from Equation 2, we get:

326.25 - 273 = 1.880 * σ + μ - (-1.880 * σ + μ)

53.25 = 3.760 * σ

Dividing both sides by 3.760, we get:

σ ≈ 14.165

Substituting this value of σ into Equation 1, we can solve for μ:

273 = -1.880 * 14.165 + μ

273 + 1.880 * 14.165 = μ

μ ≈ 302.523

Therefore, mean is approximately 302.523 cm, and the standard deviation is approximately 14.165 cm.

Let X be the duration of a particular type of criminal trial. We know that the mean of X is μ = 24 days and the standard deviation of X is σ = 8 days.

We are asked to find the 66th percentile of X, which is the value x such that P(X ≤ x) = 0.66. Using the standard normal distribution, we have Z = (X - μ) / σ ~ N(0, 1).Thus, we can write: P(X ≤ x) = P(Z ≤ (x - μ) / σ) = 0.66We need to find the value of x that satisfies this equation. Using a standard normal distribution table or calculator, we can find that the corresponding z-score is approximately 0.43.

Thus, we have:0.43 = (x - μ) / σ0.43 * 8 = x - 24x ≈ 27.44Therefore, the 66th percentile of the duration of a particular type of criminal trial is 27.44 days (rounded to two decimal places).Part (a): The 66% of all trials of this type are completed within 27.44 days (rounded to two decimal places).

The scenario is that for every fifth customer , the owner cross the four lines he makes. Thus a pack of five and easy to remember. As the data on regular week days is less, As can do the same for the third customer. Crossing the 2 lines for 3rd customer.

3.

With this provision of crossing the third customer, the owner can have a better check on the late delivery. As it will bring in his notice earlier as compared to fifth crossing.

4.

With the data as provided in the table, we can come to the conclusion that on weekends , i.e. both on time delivery and late deliveries are high in numbers. It must be because of high demand on that days. So owner must make some provision like hiring some more delivery boys for weekend in order to reduce the late deliveries.
