y-intercept is the Y value when x is 0
Y = 60
so this means if a person studies 0 hours they will get a 60 on the test
So B would be the answe
So P(-0.7537 < z < 1.3190) = 0.9063 - 0.2254 = 0.6809
A = pi * r^2
A = 3.14 * 16
A = 50.24 square inches
50.24 / 12 = _______ square inches

Answer:
D. 144
Step-by-step explanation:
a straight line is 180° so you do 180-36
Mean - is the average of something. You basically find the sum of all the numbers then divide the sum by how many numbers you added so for example I have 1,3,4and 2
To find the average you add them first to get 10 then you divide this by 4 since I added 4 numbers.
Median - is the number that falls in the middle. First you gotta sort the numbers from smallest to biggest then pick the one in the middle for example is I have 7,5,9,2and 1. I gotta sort it —-> 1,2,5,7,9 then I pick the number in the middle which is 5. So 5 is the median
Mode- is the number that appears the most times. So if I have the set 3,7,5,3,9,4,1,3 the mode would be 3 because it appears the most times
