On a standardized test the standard deviation is 30 points. Sheena scores 1023. She is told that this is 1 standard deviation above the mean. What is the mean score on the test?

Question 6 options:

1053

1000

993

993

Step-by-step explanation:

standard deviation ( ) = 30

Sheena scores = 1023 = 1 standard deviation above the mean

which can be written as;

1023 = mean () + 1

1023 = + 1 30

= 1023 - 30

= 993

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
