85 hospitals at a moment during the day gives a mean noise level of 46 db. assume that the standard deviation of noise level is really 10 db. part one. assuming that the average noise level of hospitals is what it's supposed to be, what is the probability of a sample of 85 hospitals producing an average as high as your sample (p-value)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

i have no idea just need points sorry
