Answer:
A is True
B is False
C is False
D is False
E is True
Lastly, F is False
Step-by-step explanation:
A would be= 71+27+50+50+50+48+48+47+47+45=518. Then you divide that by ten and you get 51.8
The mode is the most often reoccurring number We have 50 three times but 48 only twice.
The median is when you line all the numbers up in order and cross them out. It would look like this 71,57,50,50,50,48,48,47,47,45 however when y=we we cross the out we get both 50 and 48 in the middle when that happens we add them together and divide by two. That would get us 50+48=98/2=49 not 48
There are only two animals that can go faster than 50 mph ( The cheetah goes 57 mph and the Pronghorn antelope goes 57)
There are 7 animals faster than 47 mph so 7/10 as a percentage is 70%
The lowest and highest speed are 71 and 45 if we take those out we are left with 57+50+50+50+48+48+47+47 And that equals 49.625 which is lower than our old mean of 51.8
I hope this helps, have an amazing day!

Last year, Frank earned $7.48 per hour. This year the company decided to give him a 30% increase in his hourly rate. How much is Frank earning per hour this year? A. $7.78 O B. $9.72 O c. $10.48 D. $22.44 E $24.93
Answers
Answer:
B 9.72
Step-by-step explanation:
If we imagine 7.48 is 100% Then we can use multiply and divide to find 30%. It goes like this. x/7.48 = 30/100. Where x is the unknown. Take 30 times 7.48 which is 224.4 then divide by 100 we get 2.24 dollars. Added to 7.48 we get 9.72
Mark and his three friends ate out at Applebee's. (Hint* 4 total people) Their bill totaled $52.35. If they left the server a 20% tip, how much would each person pay splitting the bill evenly? (Round to the nearest dollar and cent)
Answers
Answer:
Unitary cost= $15.705
Step-by-step explanation:
Giving the following information:
Their bill totaled $52.35. They left the server a 20% tip.
First, we need to calculate the total cost of the meal:
Total cost= 52.35*1.2= $62.82
Now, we can split it into 4 equal parts:
Unitary cost= 62.82 / 4
Unitary cost= $15.705

Answers
Answer:
B
Step-by-step explanation:
There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.
For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.
Top left = (-3,4)
Bottom left = (-2, -4)
Top right = (3,4)
Bottom right = (1,-4)
(-3,4) is the point/dot on the top left corner.
(3,4) is the point on the top right corner.
(1,-4) is the point on the bottom right corner.
(-2,-4) is the point on the bottom left corner.

A= x^2 -30x+225 The polynomial represents the area (in square feet) of the square playground. a. Write a polynomial that represents the side length of the playground. b. Write an expression for the perimeter of the playground. (I factored it and got (x-15)^2)
Answers
Answer:
a) The polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.
b) The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].
Step-by-step explanation:
a) By Geometry, we know that area of the square is equal to the square of the side length. If [tex]A = x^{2}-30\cdot x +225[/tex] is the area of the square, then must be a perfect square trinomial, that is:
[tex](x-a)^{2} = x^{2}-2\cdot a\cdot x + a^{2}[/tex] (1)
Then, we must observe the following properties:
[tex]-2\cdot a = -30[/tex] (2)
[tex]a = 15[/tex]
[tex]a^{2} = 225[/tex] (3)
[tex]a = 15[/tex]
Therefore, the polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.
b) The perimeter of a square equals four times the side length. That is:
[tex]p = 4\cdot (x-15)[/tex]
The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].
The polynomial that represents the side length is x - 15, and the perimeter of the playground is 4x - 60
The expression of the area is given as:
[tex]A = x^2 - 30x + 225[/tex]
Expand the expression
[tex]A = x^2 - 15x - 15x + 225\\[/tex]
Factorize
[tex]A= (x - 15)^2[/tex]
The area of a square is:
[tex]A = l^2[/tex]
Where l represents the side length.
So, we have:
[tex]l = x - 15[/tex]
The perimeter is then calculated as:
[tex]P = 4l = 4*( x - 15)[/tex]
[tex]P = 4x - 60[/tex]
Hence, the perimeter of the playground is 4x - 60

The shape on the left is translated to the shape on the right.

The name of the shape on the right is M N O P Q R S prime because it is the image of the shape on the left.
The name of the shape on the right is M N O P Q R S prime because it is the pre-image of the shape on the left.

The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.
Answers
Answer:
D.) The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.
Step-by-step explanation:
So the first thing we have to do is look at the information given, we know that the shape on the left is translated into the shape on the right. When a shape is "translated" it simply means that the shape doesn't change in size or rotation it only glides or moves. So the shape on the right is the former shape and the shape on the left is the pre-image.
Knowing that the left shape is the pre-image goes ahead and eliminates answer choices B & C as both answers mention that the right side is the image before the transformation which because of what was previously mentioned, is incorrect.
This leaves only answer choices A and D. Finally we can narrow down the final answer by knowing that the apostrophe " ' " or prime should be placed after each letter not just at the end of letters. For example A'B'C'D' not ABCD'. If we apply this rule to the last to answer choices we can see that D is the correct answer.

A store is going out of business, they are advertising that "Everything is 40% Off!" You have had your eye on a new pair of shoes that were originally $156. What is the sale price of the shoes?
Answers
Answer:
$93.6
Step-by-step explanation:
The original price if this show is to be sold at $156
But the question tells us that everything is being sold with a 40% off.
So we should get 40% of 156
= 0.40 * 156
= $62.4
So this shoe would have it's new price to be $(156 - 62.4) = $93.6
So in conclusion given a 40 percent off, the sales price if the shoe would be $93.6

Show how the ordered pair (-5, -1) belong to the relation y = -x + 4.
Please fast I have a test
Answers
Answer:
(-5, -1), does not belong to the relation y = -x + 4
Step-by-step explanation:
From the question, we have;
The given ordered pair having a relation = (-5, -1)
The given relation, y = -x + 4
From the given relation, we get;
When y = -1
-1 = -x + 4
∴ -x = -1 - 4 = -5
x = 5
Similarly, when x = -5, we get;
y = -x + 4 = -(-5) + 4 = 5 + 4 = 9
y = 9
Therefore, (-5, -1), does not belong to the relation y = -x + 4 but (-5, -1), belongs to the relation y = x + 4
