Answer:
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
Step-by-step explanation:
The 68-95-99.7 rule states that, for normally distributed measures:
68% of the values are within 1 standard deviation of the mean.
95% of the values are within 2 standard deviations of the mean.
99.7% of the values are within 3 standard deviations of the mean.
(a) What range of lengths covers almost all, 99.7%, of this distribution?
Those are those values within 3 standard deviations of the mean. So
From A to B, in which
The lengths from 32.1cm to 46.5cm covers 99.7% of this distribution.
Given:
• Amount to save, A = $28,000
,
• Time, t = 6 years
,
• Interest rate, r = 5.3% ==> 0.053
,
• Number of times compounded = quarterly = 4 times
Let's find the amount that must be deposited into the account quarterly.
Apply the formula:
Where:
FV is the future value = $28,000
r = 0.053
n = 4
t = 6 years
Thus, we have:
Let's solve for P.
We have:
Solving further:
Divide both sides by 28.0384237:
Therefore, the amount that must be deposited quarterly into the account is $998.60
ANSWER:
$998.60
A= Anthony
D=Daniel
M=Mya
A=2D
M=D+6
Add them all together
A+D+M=102
Substitute
(2D)+(D)+(D+6)=102
4D+6=102
4D=96
D=24
M=D+6
M=24+6
M=$30
Hope this helps.
