Answer:
0.945200708
Step-by-step explanation:
In this question, we are asked to calculate the probability that a person selected at random would live less than 65.
To solve this problem, what we need to do is to first calculate the z-score.
Mathematically, z = (x-mean)/standard deviation
According to the question, the mean is 53 years and the standard deviation is 7.5
Substituting these values in the z-score equation:
Z-score = (65-53)/7.5 = 12/7.5 = 1.6
We proceed to use the z-score table to obtain the probability. Using the table, z score of 1.6 corresponds to a probability of
0.945200708
Answer:
16666666666/100000000000.
Step-by-step explanation:
Answer:
L - W = 2 and 2L + 2W = 68
Step-by-step explanation:
The two equations here are going to be-
Length minus width equals 2
L - W = 2
And
Length x 2 + Width x 2 = 68
2L + 2W = 68
ANSWER:
EXPLANATION:
Given:
Since U and V are Matrices with equal dimensions(3 x 3 matrix), and
X + U = V.
To solve for X, we have:
X = V - U
