You receive an inheritance of $15,500, and you place the full amount into a bank account. The bank pays a simple interest rate o
g100num [7]
To solve this we need to figure out what 7.5% of 15,500 is. (It’s 1162.5). Now we know that after one year it is a total of 16,662.5. We then figure out what 7.5% of 16,662.5 is, which is 1,249.6875. You then add that to 16,662.5 which comes out to 17,912.1875. We then figure out 7.5% of that is 1,343.4140625. We then add that to the last total which is 19,255.6015625 and we simplify that to 19,256 and we find out that the final total is $19,256. But it wants how much have we earned which means we need to subtract the original from the new, which is 3756 and we add a unit.

Meaning the final answer is $3,756.

How do we round 8.465 nearest hundredths
kiruha [24]
The second number after the decimal is the hundredths place. To round to that place, you look at the number after it. In this case 6 is the hundredths place and 5 is the number after it. If the number after it is 5 or higher, the hundredths place number increases by 1, if it is less than 5 the hundredths place number doesn't change. So the answer is 8.47.

Human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -
STALIN [3.7K]

Answer:

97.27^{o}F

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

z=\frac{x-\mu}{\sigma}, where \mu = Mean, \sigma= Standard deviation.

Let us substitute our given values in z-score formula.

-1.5=\frac{x-98.20}{0.62}

Multiply 0.62 to both sides of equation.

0.62\times-1.5=0.62\times \frac{x-98.20}{0.62}

-0.93=x-98.20

Add 98.20 to both sides of equation.

-0.93+98.20=x-98.20+98.20

97.27=x

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
