The mean is 10,724.28.
Explanation:
The mean is all of the values divided by the number of values there are.
So what you have to do is add all of the numbers and divide it by the amount of numbers there are.
10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.
Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.
Answer:
8 1/2
Step-by-step explanation:
F(1)=8000x0.55x1=4400
f(2)=8000x0.55x2=8800
(8800-4400)/2=2200
Answer:
10 units squared
Step-by-step explanation:
Looking at the figure, we can observe that it consists of two triangles: one on the left of the y-axis and one on the right. This means that we can find the separate areas of each triangle and then sum them to get the total area.
The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.
<u>Left Triangle</u>:
The base is 4 and the height is 4, so the area is:
A = (1/2) * b * h
A = (1/2) * 4 * 4 = (1/2) * 16 = 8 units squared
<u>Right Triangle</u>:
The base is 2 and the height is 2, so the area is:
A = (1/2) * b * h
A = (1/2) * 2 * 2 = (1/2) * 4 = 2 units squared
The total area is 8 + 2 = 10 units squared.
