Answer:
D
Step-by-step explanation:
When somethin is decreasing you would subtract the percent it was decreasing by, by 1.
.024 - 1 = .976
A median is the middle number of a data set.
To find it put the numbers in order.
78, 69, 69, 96, 99
Then find the middle number
78, 69, *69,* 96, 99
The median is 69
A mode is the number that appears the most in a set of numbers.
78, *69, 69,* 96, 99
The mode is 69
To find the mean or average of a set of numbers, add all the numbers together then divide by the number of numbers there are.
99+69+96+69+78 = 411
411/5 = 82.2
The mean is 82.2

Integers involve with negative, so D isn't the correct answer the correct answer will be A.
Answer:
80.56
Step-by-step explanation:
To find the rectangle area you just multiply its length by its width:
17 * 4 = 68
You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula: ![\pi*r^2](https://tex.z-dn.net/?f=%5Cpi%2Ar%5E2)
Since the radius (r) is 2 and
is 3.14, you have the following equation:
A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 <em>(A is Area)</em>
Sum the rectangle's area with the circle's area:
12.56 + 68 = 80.56
And vuoila! there's your answer.
Step-by-step explanation:
![4(y - 3) = 13 \\ \\ \therefore \: 4y - 4 \times 3 = 13 \\ \\ \therefore \: 4y - 12 = 13\\ \\ \therefore \: 4y = 13 + 12 \\ \\ \therefore \: 4y = 25 \\ \\ \therefore \:y = \frac{25}{4} \\ \\ \therefore \:y = 6\frac{1}{4}](https://tex.z-dn.net/?f=4%28y%20-%203%29%20%3D%2013%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%204y%20-%204%20%5Ctimes%203%20%3D%2013%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%204y%20-%2012%20%3D%2013%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%204y%20%20%3D%2013%20%2B%2012%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%204y%20%20%3D%2025%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3Ay%20%3D%20%20%5Cfrac%7B25%7D%7B4%7D%20%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3Ay%20%3D%20%206%5Cfrac%7B1%7D%7B4%7D%20)
