A set of data has a normal distribution with a mean of 51 and a standard deviation of 7 find the percent of data within the following interval from 30 to 72

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

40% off the regular price is the correct answer.

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
