Editors preparing a report on the economy are trying to estimate the percentage of businesses that plan to hire

The number of randomly selected employers that would have to be contacted is 9604

<h3>How to solve for the value of n</h3>

The confidence level is 95%

1 - 0.95 = 0.05

We have to get the z value at 0.05

0.05/2 = 0.025

Using the standard normal table, the critical value at 0.025 = 1.96

We have to define the probability as P = 50% = 0.5

we have to define q = 1 - 50% = 0.5

The formula that would be used to find the value of n is given as

n = pq\frac{Zc}{E} ^2

These variables used are:

pq = variance of population

E = margin of error = 0.01

critical value = Zc = 1.96

n = 0.5*0.5 (\frac{1.96}{0.01})^2

= 0.25 * 38416

= 9604

Hence the sample space is given as 9604

What is the exact value of x? 5⋅21^5x=16
IRINA_888 [86]

Answer:

x=  16 /20420505

Step-by-step explanation:

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

5(215)x=16

Step 1: Simplify both sides of the equation.

20420505x=16

Step 2: Divide both sides by 20420505.

20420505x /20420505  =  16 /20420505

x=  16 /20420505

What is the solution to the system?<br> X+3y = 5<br> 5x-3y = 7
S_A_V [24]

Answer:

x + 3y = 5

5x - 3y = 7

Add up both equations, then:

6x = 12

=> x = 2

=> y = (5 - 2)/3 = 1
