Rotations
Given a point A(x,y) on the plane. A rotation of 270° counterclockwise will map point A to A'(y,-x), i.e. we switch x and y and invert x.
The preimage of point A is located at (-1,5). When rotated 270° counterclockwise it will map to (5,1).
The image attached below shows both points

A nutritionist would like to estimate the number of times adults exercise each week. To collect information, the nutritionist emails the members of the local fitness center. Which of the following describes the bias that may arise from the results?
A- This is a convenience sample and likely overestimates the frequency of exercise.
B- This is a convenience and likely underestimated the frequency of exercise.
C- This is a voluntary response sample and likely overestimates the frequency of exercise.
D- This is a voluntary response sample and likely underestimates the frequency of exercise.
Answer:
This is a voluntary response sample and likely overestimates the frequency of exercise.
Step-by-step explanation:
I just took the unit test review. The people taking the survey took it voluntarily and it overestimates exercise because it was offered to gym members.
The statement describes the bias that may arise from the results is "This is a voluntary response sample and likely overestimates the frequency of exercise".
Given that,

The Celsius scale is devised so that 0° C is the freezing point of water (at 1 atmosphere of pressure) and 100°C is the boiling point of water (at 1 atmosphere of pressure). If you are more familiar with the Fahrenheit scale, then you know that water freezes at 32°F and boils at 212° F. The linear equation that relates temperature r measured in degrees Celsius and temperature y measured in degrees Fahrenheit is
Answer:
[tex]r=\frac{5}{9}(y-32)[/tex]
Step-by-step explanation:
The Celsius scale was developed by Swedish astronomer Andres Celsius in 1742. It is used to measure temperature in degree Celsius in which 0 degrees represents the freezing point of water, and 100 degrees represents boiling point of water at the standard atmosphere.
The Fahrenheit scale was proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. It is used to measure temperature in degree Fahrenheit in which 32°F represents the freezing point of water, and 212°F represents boiling point of water at the standard atmosphere.
Let r represent the temperature in degrees Celsius and y represent the temperature in degree Fahrenheit. The relationship between r and y is:
[tex]\frac{r-freezing\ point(^oC)}{boiling\ point\ (^oC)-freezing\ point(^oC)} =\frac{y-freezing\ point(^oF)}{boiling\ point\ (^oF)-freezing\ point(^oF)} \\\\Substituting:\\\\\frac{r-0}{100-0}=\frac{y-32}{212-32}\\\\\frac{r}{100} =\frac{y-32}{180}\\\\r= \frac{y-32}{180}*100\\\\r=\frac{5}{9}(y-32)[/tex]

April, May and June have
90
sweets between them. May has three-quarters of the number of sweets that June has.
April has two-thirds of the number of sweets that May has. How many sweets does June have?
help
Answer:
A
Step-by-step explanation:
The month of June has 40 sweets
Let the number of sweets in the month of June be P
Given that April, May and June collectively have 90 sweets
Given that May has three quarters of number of sweets as that of June
So we can write
[tex]\rm Number\; of \; sweets\; in \; May = \dfrac{3P}{4 } .......(1) \\[/tex]
Similarly it is given that April has two third of sweets as that of May month and hence we can write
[tex]\rm Number\; of\; sweets \; in \; April = \dfrac{2}{3} \times \dfrac{3P}{4} = P/2 ......(2)\\[/tex]
As the total number of sweets in April, May and June is 90
Let the number of sweets in May be "M" and in April be "A"
We can write the following equation and solve it further
[tex]\rm M + A + P = 90\\From \;equations \; (1) \; and \; (2) \\[/tex]
[tex]\rm P + 3P/4 + P/2= 90\\\\2.25 \; P = 90\\P = 40[/tex]
So we can conclude that the month of June has 40 sweets

A manufacturer produces cherry, peppermint, cinnamon, and orange-flavored gum. Each flavor is available with sugar or sugar-free. The gum
is sold in 2 ounce, 4-ounce, or 8 ounce packages,
How many different types of labels will the manufacturers have to produce?
Answer: The total number of different types of labels will the manufacturers have to produce = 24.
Step-by-step explanation:
Given: Choices for flavours = 4
Choices for sugar = 2 {either sugar or sugar free}
Choices for the qunatity = 3
By Fundamental counting principle,
Total number of different types of labels will have to produce = (Choices for flavors) x (Choices for sugar)x (Choices for the quantity )
= 4 x 2x 3
=24
Hence, the total number of different types of labels will the manufacturers have to produce = 24.
Which step should be taken to find the quotient of 132.9 ÷ 1,000?
A. Move the decimal point in 132.9 two places to the right.
B. Move the decimal point in 132.9 two places to the left.
C. Move the decimal point in 132.9 three places to the right.
D. Move the decimal point in 132.9 three places to the left.
Answer:
D. Move the decimal point in 132.9 three places to the left.
Step-by-step explanation:
Multiplication of a decimal by the nth power of 10:
We move the decimal point n places to the right.
Division of a decimal by the nth power of 10:
We move the decimal point n places to the left.
In this question:
There is a division by 1000, which is the 3rd power of 10, because [tex]10^3 = 1000[/tex]
So, we should move the decimal point three places to the left, and the correct answer is given by option D.

a rectangular tray is 820mm long and 400mm wide .find its area in m²
Answer:
0.328 [tex]m^{2}[/tex]
Step-by-step explanation:
820mm = 82cm = 0.82m
400mm = 40cm = 0.40m
0.82 x 0.40 = 0.328
If a rectangular tray is 820mm long and 400mm wide. Its area in m² will be: 0.328m²
Using this formula
Area=Length × Width
First step is to covert from millimeter to meter
1 millimeter=0.1 centimeter
Hence:
Length=820mm×0.1÷100
Length=0.82m
Width=400mm×0.1÷100
Width= 0.40m
Let plug in the formula
Area=0.82m x 0.40m
Area= 0.328m²
Inconclusion If a rectangular tray is 820mm long and 400mm wide. Its area in m² will be: 0.328m².
