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.

The lengths of HJ and JK are 50 and 72 respectively.
Given: J is between H and K. the length of HJ=2x+4, JK=3x+3, and HK=22.
The line HJ and JK are collinear then the total length is given as: HJ+JK=HK
substitute values
⇒ (2x+4)+(3x+3)=22
⇒ 5x+7=22
⇒ 5x=22-7
⇒ 5x=15
⇒ x=3
Thus, the length of HJ is (2x+4)=(2*3+4)=10
And the length of JK is (3x+3)=(3*3+3)=12

Explanation:
The number of times the 6-sided number cube will be rolled will is
Let the numbers greater than 4 be represented below as
The number of sample space will be
The probability of rolling a number greater than 4 will be calculated below as
Hence,
To calculate the number of times a number greater than 4 will be rolled will be calculated below as
Hence,
The final answer is
Answer:
x>17/9
Step-by-step explanation:
-3(x-2) < 1/3
-3x+6 < 1/3
-3x < 1/3-6
-3x < -17/3
x > 17/9
39% has the same value as .39
