28th term of -242, -251, -260
Vedmedyk [2.9K]

Answer:

-485

Step-by-step explanation:

Formula

<em><u>Givens</u></em>

an = a28

n = 28

a1 = - 242

<em><u>Solution</u></em>

d = a3 - a2

d = -260 - - 251

d = -260  + 251

d = - 9

an = a1 + (n-1)d

an = -242 + (n - 1)(-9)

a28 = - 242 + 27*(-9)

a28 = - 242 - 243

a28 = - 485

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!
