The answer is 3...........
18% of 50 people said they liked strawberry. The word 'of' in math means multiply, so 18%•50 or .18•50. Multiply them together: .18•50=9.00 or just 9. 9 people like strawberry ice cream :)
Given that mean=56.1 and standard deviation=8.2, P(x>67.5) will be found as follows:
The z-score is given by:
z=(x-μ)/σ
thus the z-score will be given by:
z=(67.5-56.1)/8.2
z=11.4/8.2
z=1.39
thus
P(z=1.39)=0.9177
thus:
P(x>67.5)=1-P(z>0.9177)
=1-0.9177
=0.0823
Answer: A. 0.0823
Answer:
A. and C.
if you simplify the expressions, you will see which ones are equal to the expression given
Slope (y2-y1)/(x2-x1)
(-3-9)/(15-19) = -12/-4 = 3
The slope is 3
