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.

To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.
To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).
8 * 5.35 = $42.80
However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)
$42.80 * 0.15 = $6.42
Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.
$42.80 + $6.42 = $49.22
Coach Velez spent $49.22 in all.

Answer:
Step-by-step explanation:
Given that in a genetics experiment on peas, one sample of offspring contained 376 green peas and 117 yellow peas.
Total no of peas = 376+117=493
No of green peas = 376
Probability of selecting a green pea =
Yes it is reasonably close to 3/4 = 0.75 since difference is only 0.0127 negligible.
