Perpendicular lines AB and CD Intersect at point E. If m<AED=×+20, wha is the value of x

vladimir1956 [14]

Answer:

x = 70°

Step-by-step explanation:

Itz given that AB & CD are perpendicular to each other and intersect at E . So , angle(AED) = 90°

But here the value of angle(AED) = 90°

So,

x + 20 = 90°

=> x = 90° - 20°

= 70°

You plan to conduct a survey to find what proportion of the workforce has two or more jobs. You decide on the 95% confidence lev

Vikentia [17]

Answer:

865

Step-by-step explanation:

We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.

Now we have the following formula:

n = [z / E] ^ 2 * (p * q)

where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.

Replacing these values we are left with:

n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]

n = 864.36

865 by rounding to the largest number.
