Answer:
172.12 sq in
Step-by-step explanation:
The figure is comprised of a semicircle, and 2 rectangles
Area of semicircle = 1/2(3.14)4^2 = 25.12
Area of rectangle with length of 9 and width of 7 = 7(9) = 63
Area of rectangle with length of 14 and width of 6 = 6(14) = 84
Total area = 25.12 + 63 + 84 = 172.12 sq in

O(-1,1)
Answer:
B.
Step-by-step explanation:
GIven that and , and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:
The location of B is now determined after algebraic handling:
Then:
Which corresponds to option B.
The coordinate of point B will be (4, -2). Then the correct option is B.
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Point A is located at (-2, 2), and point M is located at (1,0).
If point M is the midpoint of AB.
Then the location of point B will be
We know that the mid section formula
Then the formula can be written as
x₂ = 2x - x₁ and y₂ = 2y - y₁
Then we have
x₂ = 2 × 1 + 2
x₂ = 4
y₂ = 2 × 0 - 2
y₂ = - 2
Then the coordinate of point B will be (4, -2).
Thus, the correct option is B.

b) To estimate the mean salary of professors at her university, Patricia collects data by recording the salaries of all professors included in 12 randomly selected departments.
c) Elizabeth wants to estimate the mean height of students at her school. She collects data by selecting a random group of students within her classroom.
d) To estimate the mean grade point average of students at her school, Annie collects data by recording the grade point average of every 25th student on the list of students after randomly selecting first student.
Answer:
(C) Elizabeth wants to estimate the mean height of students at her school. She collects data by selecting a random group of students within her classroom.
Step-by-step explanation:
In option C, the sample is an example of convenience sampling, It is not representative of the population of student being studied.
Convenience sampling is a type of non-probability sampling method in which the sample is taken from the part of the population easy to reach.
The sample are not chosen at random thereby undermining the ability to generalize the results from the sample to the entire population under study.
Answer:
Step-by-step explanation:
Hotel room = 87.00 a double room means for two people
breakfast = 9.00 X 2 = 18.00
Lunch 14.00 X 2 = 28.00
Dinner 16.00 X 2 = 32.00
add the amounts all together 87 + 18 + 28+ 32 =$165.00 for 2 people
If temperature in potter's kiln dropped 760 degrees in 4 hours. On average, 190 degrees of temperature drop per hour
A division is a process of splitting a specific amount into equal parts.
Given,
The temperature in potter's kiln dropped 760 degrees in 4 hours
We need to find the average of temperature drop per hour
To find this we have to divide 760 by 4.
Seven hundred sixty divided by four.
760/4
One hundred ninety
190
For an hour 190 temperature is dropped.
Hence, On average 190 temperature drop per hour.
