Answer:
c)=
Step-by-step explanation:
The probability that a data value is between 54 and 66 is 81.9%
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:

Given that μ = 62, σ = 4
For x = 54:

For x = 66:

P(54 < x < 66) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 81.9%
The probability that a data value is between 54 and 66 is 81.9%

A = 6
b = 9
c = -10
hope this helps you!
6/11 or about 55%
To put into a fraction the total is the denominator and the 6 would be the numerator as it is the real diamond then divide the numerator by the denominator move your decimal two places round as needed
Y= 2x+4, because when you plug in x and y you then solve for b and get 4. The 2x is the same because the slope stays the same on parallel lines.
