Answer:
The Estimate the number of students who took the scores between 82 and 98 = 16
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data The scores on a math test are normally distributed with a mean μ = 74
standard deviation of Population
S.D (σ) = 8
Let 'x' be the random variable of Normal distribution
<u><em>case(i)</em></u>:- when x = 82
<u><em>case(ii)</em></u>:- when x = 98
The probability that test scores between 82 and 98.
P(82≤x≤98) = P(1≤z≤3)
= P(z≤3) - P(z≤1)
= 0.5+A(3)-(0.5+A(1))
= A(3) -A(1)
= 0.4986 - 0.3413
= 0.1573
<u><em>Final answer</em></u>:-
The Estimate the number of students who took the scores between 82 and 98
= 100 X 0.1573 = 15.73 ≅16

Answer:
- Well let's look at the roots and define a parent function
- x=-2.5 x=0 x=4
- Now let's define the function
- y=(x+2.5)^2(x-4)
Your graph is missing the y axis
