20% is .20/ 20/50 is 40% or .4 or 4/10/ 9% is .09 or 9/100 / 9/10 is 90% or .9/ 66% is .66 or 33/50 or 66/100/ 6/10 is 60% or 60/100 or .6/ 2% is .02 or 1/50 or 2/100. I didn't exactly understand the question, but I hope this answers your question.
Since the sample size is too small (n = 9, which is less than 10) we cannot use the normal model to describe the entire population.
Therefore, we expect the sample mean to be different from the population mean.
Domain is the set of x-values and range is the set of images f(x).
x F(x) = x + 7
-9 -9 + 7 = -2
-8 -8 + 7 = -1
-7 -7 + 7 = 0
-6 -6 + 7 = 1
-5 -5 + 7 = 2
-4 -4 + 7 = 3
-3 -3 + 7 = 4
So the range is {-2,4} <------ answer
Answer:
169
Step-by-step explanation:
Square root means what number times its self is a different number. In this case, 13 times 13 = 169 so 13 times itself is 169.
