Answer:
Step-by-step explanation:
First, convert the 4 mins into hours by dividing by 60;
4/60 =0.067
Add 0.067 to 75 hrs to get the total = 75+0.067 = 75.067
Therefore the total time Chris needs to make up for is 75.067 hrs
Total number of days Chris has = 25
Next,
IF in 25 days = he can cover 75.067hrs
then in 1 day he will cover = (1 * 75.067)/ 25
= 3.002
Therefore, Chris needs to do 3hrs each day to be able to complete the deadline
B, 190.
First you find the area of the circle (pi times radius squared) however, since you are given diameter, you must find radius by dividing diameter by 2. So, your radius is 9, then you plug it into the formula and you get 254.5. After multiplying this by 0.75 because you only want to find 75 percent of the area, you get the answer of 191m
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

Answer:
23.5 inches^2
Step-by-step explanation:
Area of triangle = 1/2 * base * height
area = 1/2 * (5+2) * (5+4)
area = 31.5 in^2
Area of rectangle = length * breadth
area = 4 * 2
area = 8 in^2
Area of figure = area of triangle - area of rectangle
area = 31.5 - 8
area =23.5 in^2
