Using the Empirical Rule, it is found that the standard deviation of the sample is of:
C. 4
By the <em>Empirical Rule</em>, 95% of the measures are within 2 standard deviations of the mean, that is, between 2 standard deviations below the mean and 2 standard deviations above the mean.
95% of people's heights are <u>between 168 and 184 centimeters</u>, hence, there are 4 standard deviations between 168 and 184 centimeters. Then:
Hence, option C is correct.
A similar problem is given at brainly.com/question/25807482
H(t) = -16t^2 +704t = -16(t^2 -44t)
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)
The side of a square is the square root of the area.
Side = sqrt(155)
Side = 12.45 inches. (Round answer as needed)
Answer:
72 trees.
Step-by-step explanation:
27 divided by 3 equals 9. so that means Matt can plant 9 trees in one hour so 9 is our unit rate ( what we multiply by) so now you multiply 9 by 8 and your answer is 72
