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
False.
Only log(x^2)=2log(x)
For example, let x=10
(log(10))^2=1^2=1
yet 2log(10)=2*1=2
Answer:
$ 2330
Step-by-step explanation:
a = $240
Earning at the end of fifth week = $ 680
increase in earnings per weak = ( 680 -240)/2 = 440/2 =110
d =110
l = a + (n-1)d
a20 = 240 + (19 * 110 ) = 240 + 2090 = 2330
Answer:
