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.

sorry friend I need some points and ya posted 3 of em
Step-by-step explanation:
The pair of numbers that have the greatest common factor of 3 are:
6 and 9
18 and 15
3 and 9
<h3>What is
greatest common factor?</h3>
The biggest number, which is the variable of at least two number is known as the Best Normal Element (GCF). It is the biggest number (factor) that partition them bringing about a Characteristic number. When every one of the elements of the number are found, there are not many variables which are normal in both.
The factors of 6 and 9 are:
6 ⇒ 1, 2, 3 and 6
9 ⇒ 1, 3, 9
The greatest common factor here is therefore 3.
The factors of 18 and 15 are:
18 ⇒ 1, 2, 3, 6, 9 and 18
15 ⇒ 1, 3, 5, and 15
Greatest common factor is also 3
The factors of 3 and 9 are:
3 ⇒ 1 and 3
9 ⇒ 1, 3, 9
Greatest common factor here is also 3.

Answer:
y= x+1
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Gradient of line = 
Using the above formula,
Gradient
Thus m=1. Substitute m=1 into the equation:
y= 1x +c
y= x +c
Susbt. a coordinate.
When x=3, y=4,
4= 3 +c
c= 4-3
c=1
Thus, the equation of the line is y= x+1.
