Assume that adults have IQ scores that are normally distributed with a mean 105 of and a standard deviation 20 . Find the probab

ArbitrLikvidat [17]

Answer:

0.6048

Step-by-step explanation:

Given the following :

Assume a normal distribution :

Mean (m) = 105

Standard deviation (sd) = 20

Find the probability that a randomly selected adult has an IQ between 88 and 122 .

Z = (x - m) / sd

For IQ score of 88:

Z = (88 - 105) / 20

Z = (-17) / 20

Z = - 0.85

For IQ score of 122:

Z = (122 - 105) / 20

Z = (17) / 20

Z = 0.85

P(-0.85<Z<0.85) = P(Z < 0.85) - P(Z < - 0.85)

P(-0.85<Z<0.85) = (0.8023 - 0.1977)

P(-0.85<Z<0.85) = 0.6048

Use the given angle measures to answer the following questions.

ra1l [238]

Answer:

$\Huge\boxed{A.8}$

Step-by-step explanation:

Hello There!

If you didn't know vertical angles are congruent

That being said we can use this equation to solve for x

40 = 5x

Objective: Isolate the variable using inverse operations

To get rid of the 5 we divide each side by 5

40 / 5= 8

5x/5=x

we're left with x=8

To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct

5(8) = 40

So the answer would be 8
