By graphing both equations, we see that the solutions of the system of equations are (1.05, 4.05) and (-4.97, - 1.97)
<h3>How to solve the system of equations?</h3>Here we have the system of equations:
y = x + 3
y = 13*(x + 5)*(x - 1).
To solve this system graphically, we need to graph both equations and see where the curves intercept.
The graph of the two equations can be seen below.
There are two solutions, one is (1.05, 4.05) and the other is (-4.97, - 1.97)

Answer: a) 0.6141
b) 0.9772
Step-by-step explanation:
Given : Mean :
Standard deviation :
The formula for z -score :
a) Sample size = 1
For x= 63 in. ,
The p-value =
Thus, the probability is approximately = 0.6141
b) Sample size = 47
For x= 63 ,
The p-value =
Thus , the probability that they have a mean height less than 63 in =0.9772.
