Answer:
This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
Step-by-step explanation:
The past year showed an average life span of 71.8 years.

Population standard deviation = 8.9 years

We are supposed to find the mean life span today is greater than 70 years
i.e. P(X>70)
Formula : 

Z=−0.202
P(X<70)=0.4129
P(X>70)=1-P(X<70)=1-0.4129=0.5871
Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
Interest earned
7,500×0.055
=412.5
Deduct tax
412.5−412.5×0.2
=330
Add the remaining interest
330+7,500
=7,830
Calculate interest earned in the second year
7,830×0.055
=430.65
Deduct tax
430.65−430.65×0.2
=344.52
Add the remaining interest
344.52+7,830
=8,174.52. ...answer
Answer:
50 is the answer because you can divide 2 numbers to get this number.

Answer:
Common difference
Next three terms
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Find the common difference by subtracting the previous term from a term. We can use the terms 1/4 and 1/2:
Convert 1/2 into a fraction over 4:
1/2 · 2/2 = 2/4
Find the common difference by subtracting the fractions:
2/4 - 1/4 = 1/4. This is the common difference.
Find the next 3 terms by adding 1/4:
5/4 + 1/4 = 6/4 (Reduce fraction) = 3/2
6/4 + 1/4 = 7/4
7/4 + 1/4 = 8/4 (Reduce fraction)
Therefore, the next 3 terms are 3/2, 7/4 and 2.
Answer:
Following are the solution to the given question:
Step-by-step explanation:
The population std. dev of the dog weight=8
Calculating the payout w s.t:
therefore, we assume that the weight of the dog is a normal distribution with std. deviation that is 8.
