Find the solution set of the inequality:

-3x + 8 < 15

Answer: 90 degrees to 120

Step-by-step explanation:

The probability of a temperature from 90 degrees to 120 degrees.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Experiment: A trial or an operation conducted to produce an outcome is called an experiment.

Sample Space: All the possible outcomes of an experiment together constitute a sample space. For example, the sample space of tossing a coin is head and tail.

Favorable Outcome: An event that has produced the desired result or expected event is called a favorable outcome. For example, when we roll two dice, the possible/favorable outcomes of getting the sum of numbers on the two dice as 4 are (1,3), (2,2), and (3,1).

Trial: A trial denotes doing a random experiment.

Given:

Temperatures from 60 degrees to 160 degrees.

As, per the situation the probability will lie between 60 degree to 160 degree.

Hence, The probability of a temperature from 90 degrees to 120 degrees.

Answer:

The solution is [tex]x = \frac{1}{2}[/tex]

Step-by-step explanation:

To solve this exponential equation, we must write both sides as powers of 3.

The equation given is:

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

Since [tex]3^3 = 27[/tex], we have that [tex]3^{-3} = \frac{1}{3^3} = \frac{1}{27}[/tex], so[tex]\frac{1}{27} = 3^{-3}[/tex]

Then

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

[tex]3^{7x + 4} = (3^{-3})^{x-3}[/tex]

[tex]3^{7x + 4} = 3^{-3(x-3)}[/tex]

[tex]3^{7x + 4} = 3^{-3x + 9}[/tex]

Since both sides are now powers of 3, we can equal them:

[tex]7x + 4 = -3x + 9[/tex]

[tex]10x = 5[/tex]

[tex]x = \frac{5}{10}[/tex]

[tex]x = \frac{1}{2}[/tex]

The solution is [tex]x = \frac{1}{2}[/tex]

Answer:

0.9955

Step-by-step explanation:

Given :

Mean weight increase , μ = 14

Sample mean weight increase , xbar = 16.3

Standard deviation, s = 5.9

Sample size, n = 45

Hypothesis :

H0 : μ = 14

H1 : μ > 14

The test statistic : (xbar - μ) ÷ (s/sqrt(n))

Test statistic = (16.3 - 14) ÷ (5.9/sqrt(45))

Test statistic = 2.3 / 0.8795200

Test statistic = 2.615

The Pvalue :

P(Z < 2.615) = 0.99554

Hence, pvalue = 0.9955 (4 decimal places).

Remark

I don't think you need the quadratic formula for this equation. It just factors into (b - 2)(b - 2), but I'll do it because you requested it.

Formula

[tex]\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}[/tex]

a = 1

b = - 4

c = 4

Solution

x = - - 4 +/- sqrt((-4^2) - 4*1*4)

Answer:

c. PROPOSITION ONE is false and PROPOSITION TWO is true

Step-by-step explanation:

In this question, we have that:

pvalue of 0.058

Significance level of 0.05

The pvalue is larger than the significance level, which means that there is no statistically significant association(Propostion One is false), and the null hypothesis is not rejected, that is, it is proved, so Proposition Two is true.

This means that the correct answer is given by option C.

Answer:

18 11/15

Step-by-step explanation:

This is the answer because:

1) First, find the common denominator: 12 1/3 = 12 5/15 and 6 2/5 = 6 6/15

2) Then add the fractions: 12 5/15 + 6 6/15 = 18 11/15

3) 18 11/15 is reduced to the lowest terms because 11 is a prime number.

Therefore, 18 11/15 is the answer.

Hope this helps! :)

it's an unfair question b/c we have to know if it's out of all girls or out of all kids.  So we need to know the population total.   so if it was just girls the it's

3/45 = 0.0666666666666...

if it's out of kids.. then it's  3/123= 0.02439....

so that's the two choices.. which one is on the list of choices? both are so that's why this is an unfair question.  maybe this is more to the question not shown in the picture?  hmmmm

Answer:

Diagonal = 13 yd

Step-by-step explanation:

The diagonal of the 3D shape can be solved using the extension of the pythagorean theorem, which is given as: d² = a² + b² + c²

Where,

a = 12 yd

b = 3 yd

c = 4 yd

d = diagonal

Plug in the values

d² = 12² + 3² + 4²

d² = 169

d = √169

d = 13 yd

Answer:

He needs 92 on his last test.

Step-by-step explanation:

Mean score:

The mean is the sum of all scores divided by the number of tests.

In this question:

Scores of 85, 89, 85, 89 and x(the last one).

5 tests.

We want a mean of 88. So we find x for a mean of 88.

[tex]\frac{85 + 89 + 85 + 89 + x}{5} = 88[/tex]

[tex]348 + x = 440[/tex]

[tex]x = 440 - 348 = 92[/tex]

He needs 92 on his last test.
