Answer:

<em>z-score will be: 7.741.... and it will be unusual. </em>

Step-by-step explanation:

Human body temperatures have a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit.

So here, $\mu= 98.20$ and $\sigma= 0.62$

<u>Formula for z-score</u> is: $z= \frac{X-\mu}{\sigma}$

Thus, the z-score for 103.00 degrees Fahrenheit will be.......

$z(X=103.00)= \frac{103.00-98.20}{0.62}=7.741...$

As, here the z-score is more than 2 standard deviations above the mean, so 103.00 degrees Fahrenheit is unusual for human body temperature.

You have $20 in your bank account. You are out shopping at a video store with a

Butoxors [25]

This problem is a simple matter of subtraction.
We know our starting balance, which is 20. If we are buying something with our money, we are subtracting the amount we spend from the amount we have. If we're buying a DVD that costs 32 dollars, we subtract 32 from our starting balance, which is 20.

20 - 32 = -12

So, your account balance after you buy the DVD is -12. This means you are twelve dollars in debt.
