Which of the following equations is equivalent to 5(2p-6)=40
Maurinko [17]

Question

Which of the following equations is equivalent to 5(2p-6)=40?

Let's solve your equation step-by-step.

5(2p−6)=40

Step 1: Simplify both sides of the equation.

5(2p−6)=40

(5)(2p)+(5)(−6)=40(Distribute)

10p+−30=40

10p−30=40

Step 2: Add 30 to both sides.

10p−30+30=40+30

10p=70

Step 3: Divide both sides by 10.

10p/10=70/10

p=7

ANSWER =

The answer is A. because...


10p−30=40  =  p=7


ANSWER = A.



hope i helped have a wonderful day..can i get a brainliest please and thank you...

Tanzania [10]

Answer:

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

560 random tests conducted, 26 employees failed the test. This means that n = 560, \pi = \frac{26}{560} = 0.046

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.33.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 - 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.025

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 + 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.067

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).
