Answer:
(0,-3)
Step-by-step explanation:
hi, with this we can just do substitution (substitute x for y+3)
6(y+3)-5y=15
evaluate
6y+18-5y=15
y+18=15
y=-3
then we plug that in
x=-3+3
x=0
Answer:
Spencer is correct
Step-by-step explanation:
Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer
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.
