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

Three consecutive integers add up to -36. What are the integers?​
nasty-shy [4]

Answer:

We know our answer is correct because 11 + 12 + 13 equals 36 as displayed Below

Explanation

3X + 3 = 36 3X + 3 - 3 = 36 - 3 3X = 33 3X/3 = 33/3 X = 11 Which means that the first number is 11, the second number is 11 + 1 and the third number is 11 + 2. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13. 11 + 12 + 13 = 36 We know our answer is correct because 11 + 12 + 13 equals 36 as displayed above. Therefore, three consecutive integers that add up to 36 are 11, 12, and 13.  11 + 12 + 13 = 36

tangare [24]
There is a 1/2 chance that he will get at least one of the two features.

There are 3 x 4 = 12 possibilities. There are all 4 colors of each 3 sizes.

All 4 of the medium trucks have one of the features.

For the other 2 sizes, only the red truck will have one of the features.

There are 4 + 2 = 6 possibilities out of 12 for a chance of 6/12 or 1/2.

Daniel wants to create a banner for his construction business to hang at the house he just built. Daniel will use a single sign
Nina [5.8K]
The solution for this problem is just simple. It tells you to find the area in square feet. Thus, convert the units to feet first. The conversion you need to know are: 12 in = 1 ft and 3 ft = 1 yard.

Width = 42 in * 1 ft/12 in = 3.5 ft
Length = 10 yards * 3 ft/1 yard = 30 ft

Area = Length*Width = 30*3.5
<em>Area = 105 ft²</em>
