Answer:
The variable t is equal to 9.
Step-by-step explanation:
We are given t • 7 = 63. To solve this for t, we divide both sides of this equation by 7, obtaining:
t = 63/7 = 9
The variable t is equal to 9.
They each have $42 because 7 times 6 is 42 and combined they have $84 because 42 + 42=84.

Answer:
98 is your answer
Step-by-step explanation:
When the population mean and standard deviation are known, you use the standard normal distribution
<h3>How to determine the distribution?</h3>
There are several probability distributions; these include
- Normal distribution
- Poisson distribution
- Chi square distribution
- Binomial distribution
- Etc
Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,
Note that it is also referred to as the z-distribution
