Using the normal distribution, it is found that the correct option is:
In a <em>normal distribution</em> with mean
and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
In this problem:
- The mean on the Wechsler Scale is of 100, hence
.
- The standard deviation is of 17, hence
.
- Brianna had an score of 117, hence

Then:



Hence, the option d is correct.

That means the average of all data point equal:
(99+122+103+113+109+x)/6 = 103
===> (546+x)/6 = 103===> 546+x=618 & x=618-546=72, so x =72
X^4+y^4=81
there are 2 solutions
x=0 x=3
y=3 or y=0
f(x,y)=3^2+0^2=9 is a constant who has the graph a line || Ox
Answer:
36
Step-by-step explanation:
First you would solve what's in the parenthesis because the Order of Pemdas.
Second you would multiply the answer of what's in the parenthesis which is 3 to 12.
Third you would get the answer which is 36!
It is letter C (look carefully)
