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.

Answer:
Er... um... huh?
Step-by-step explanation:
Answer:
$251
Step-by-step explanation:
To get this amount, we simply find o.4% of 250.
That equals 0.4/100 × 250 = 1.
This means she would have earned an interest amounting to $1 after the first month.
The total amount of money in her account after the first month = 250 + 1 = 251
Hence, she would have an amount of $251 in her account after the first month.
16 out of 24 would equal around 67%, and that as a grade would be a D.
However, grades MAY vary from school to school.
But on average:
A= 100 through 90, B= 89 through 80, C= 79 through 70, D= 69 through 60, and an F= 59 and below that.
Keep in my mind that if your grade has digits after the decimal, it will be rounded (in your case) and that may also change your grade, for example if your grade is 79.7%, then it will be rounded to 80%, and your grade will be a B.
Answer:
As we know that probability value must always be between 0 and 1, it can not be greater than 1 and it can not be less than zero or any negative values
A. Number 175% = 1.75 which is greater than 1, so cannot be the value of probability
B. The number 5.91 could not be a probability because it is larger than 1, to be the probability value the number must be greater than or equal to 0 and less than or equal to 1.
C. The number 0.66 can be a probability value because it lies in range 0 and 1.
D. The number 0.002 can be a probability because it is greater than zero and less than 1
E. The number negative 110% could not be a probability because it is negative. Yes probability can not be negative
