Answer:

D. 40

Step-by-step explanation:

We have been given an equation \frac{1}{2}x=20. We are asked to solve our given equation for x.

Let us solve for x using opposite operations.

2*\frac{1}{2}x=2*20

x=40

Therefore, the value of x is 40 and option D is the correct choice.

Twenty four(24) minus 1/3
frosja888 [35]
23 and 2/3
you have 24 and you are taking away 1/3 of a whole
1/3 is equal to .333333333 repeating, as a decimal
therefore 1/3 is less than 1
you are taking away 1/3 of 1 away from 24
1 is equal to 3/3
take away 1/3 and you are left with 2/3
3/3-1/3=2/3
2/3 + 23 (the number that you did not touch)
and you are left with 23 2/3

Iq scores are normally distributed with a mean of 100 and a standard deviation of 15 what is the probability that a randomly sel
a_sh-v [17]
So we are given the mean and the s.d.. The mean is 100 and the sd is 15 and we are trying the select a random person who has an I.Q. of over 126. So our first step is to use our z-score equation:

z = x - mean/s.d.

where x is our I.Q. we are looking for

So we plug in our numbers and we get:

126-100/15 = 1.73333

Next we look at our z-score table for our P-value and I got 0.9582

Since we are looking for a person who has an I.Q. higher than 126, we do 1 - P. So we get

1 - 0.9582 = 0.0418

Since they are asking for the probability, we multiply our P-value by 100, and we get 

0.0418 * 100 = 4.18%

And our answer is

4.18% that a randomly selected person has an I.Q. above 126
Hopes this helps!
