Waldo and Freddy caught fish one weekend. The dot plots show the lengths of the fish they caught.
Which statement about the lengths of the fish caught by Waldo and Freddy appears to be true?
Answer:
C
Step-by-step explanation:
Freddy has a range of 22-15 while Waldo's range is 21-15. Thus, Freddy has a range of 7, greater than Waldo's 6.
The true statement is B. The median length of the fish caught by Waldo is greater than Freddy's.
What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
The data for Waldo's and Freddy's fish are not skewed to the right.
The median length of Waldo's fish is 18.82 inches and the median for Freddy's fish is 18.76, so the median length of waldo's fish is greater.
No need to check the other statements as only one statement would be true.

Jerome is painting a rectangular toolbox that is 20 inches by 10 inches by 8 inches. A tube of paint covers 300 square inches. Part B How many tubes of paint should Jerome buy?
Answer:
2.93 but rounding because he must purchase whole tubes: 3.
Step-by-step explanation:
So, to figure this out, we must recall the formula for sufrace area of a rectangle:
2*L*H+2*L*W+2*W*H
This is a bit long, so lets break it up into 3 seperate segments, and plug in values:
2*L*H
Plug in the values:
2*20*10
=
400
2*L*W
Plug in the values:
2*20*8
=
320
2*W*H
Plug in the values:
2*8*10
=
160
Now that we have solved for each segment, lets add them together to get our total surface area:
400+320+160
=
880
So this is the surface area.
Now, we know that a tube of paint covers 300 of the 880 surface area.
To find the exact amount, lets divide the 880 by the 300:
[tex]\frac{880}{300}[/tex]
Simply:
[tex]\frac{44}{15}[/tex]
This is sligthly less than 3, and doing it out, you actually get 2.93 with the 3 repeating.
Now we need to think about something. Lets say you are going to the grocery store, and you need 1.895893 lettuce. Do you think you will find 1.89 lettuce? No, you could get 1 or 2, but not 1.89 lettuce, that just doesnt make sense.
It is the same thing here, we have to round up. Note that when doing problems such as these, you will never round down. If you need 1.253 tubes of paint, you arent going to get 1. You are going to need 2. So note that you will always round up when you solving a problem like this.
So your answer is 3.
Hope this helps!

Step-by-step explanation:
The easy way to do this is to look at it graphically. an inverse function is reflected across the line y=x. f(x)=x(x-1) is an upward opening parabola when reflected, there are two y-values for all positive values of x. A function can only have one y for every x.

There are 4 blocks in the top of first tier of a pyramid. 8 blocks in the second tier. 16 in the third tier. 32 in the fourth tier. How many in the 12 tier?
Answer: 8192
Step-by-step explanation:
If you want to use an equation, the equation to solve this problem is 4 • (2^x-1).
You're looking for the 12th row so replace 12 for x.
4 • (2^11) = 8192

Consider the equations below:
y = 2x and 6x = 3y + 5
Are the lines parallel or perpendicular?
A Parallel because the product of the slopes is -1.
B Parallel because the slopes are the same.
C Perpendicular because the product of the slopes
is -1.
D Perpendicular because the slopes are the same.
==========================================================
Explanation:
Let's solve 6x = 3y + 5 for y
6x = 3y + 5
6x-5 = 3y
3y = 6x-5
y = (6x-5)/3
y = (6x)/3 - (5/3)
y = 2x - (5/3)
This final equation is in the form y = mx+b with m = 2 as the slope and b = -5/3 as the y intercept.
With the equation y = 2x, aka y = 2x+0, the m and b values are m = 2 and b = 0 respectively.
We see that both equations have the same slope (m = 2), but different y intercepts. Therefore, the two lines are parallel. If both y intercepts were the same as well, then we'd be talking about the same identical line.
If the slopes multiplied to -1, then the lines are perpendicular. In any other case, the two lines are neither parallel nor perpendicular.

Answer:
The center of the circle;
(2, -1)
The radius of the circle;
r = 4
Step-by-step explanation:
The first step is to complete the square on both x and y;
x^2 + y^2 -4x + 2y - 11 = 0
x^2 -4x +y^2 +2y = 11
We determine c1 to complete the square on x;
c1 = (b/2)^2
c1 = (-4/2)^2 = 4
We then determine c2 to complete the square on y;
c2 = (2/2)^2 = 1
The equation of the circle is then re-written as;
x^2 -4x + 4 +y^2 +2y + 1 = 11 +4 +1
We then factorize the expressions in x and y separately;
(x-2)^2 + (y +1)^2 = 16
The center of the circle is thus;
(2, -1)
The radius is the square root of 16;
r = 4
find the attached.

[tex] \sf \: 5(x - 9) + 3(x + 4) = 2(x - 6)[/tex]
Answer:
[tex] \huge{x = \frac{7}{2} }[/tex]
Step-by-step explanation:
5(x - 9) + 3(x + 4) = 2(x - 6)
First expand the terms in the bracket
That's
5x - 45 + 3x + 12 = 2x - 12
Simplify
8x - 33 = 2x - 12
8x - 2x = 33 - 12
6x = 21
Divide both sides by 6
[tex] \frac{6x}{6} = \frac{21}{6} \\ x = \frac{21}{6} [/tex]
Simplify
We have the final answer as
[tex]x = \frac{7}{2} \\ [/tex]

Use the net to find the size of the base and the height of each triangular face of this square pyramid. Enter your answers in the boxes.
Answer:
The answer is below
Step-by-step explanation:
The size of each box in the grid is 1 unit by 1 unit.
From the image, we can see that the size of the base of the square pyramid is 4 units by 4 units, hence:
Area of the base = 4 units * 4 units = 16 unit²
Also, as shown in the image, all the triangular face of the square pyramid are of the same size. the distance from the middle of the triangle base to the top of the vertex of the triangle is considered to be the height of the triangle. Hence, the height of each triangular face = 2 units

Answer:
Both 4x^2 and 64 are perfect squares
Step-by-step explanation:
If you are looking for the difference of squares, the two terms both have to be squares. We know that 64 is a square because it is 8 x 8. Also, we can say 4x^2 is a square because it can also be written as (2x)^2. We are basically looking for an option that tells us that they are square. This is option 1.
The second option is invalid because being an even number does not mean the number is a square.
The third option does not help the case much either. Just because there is a common perfect square factor, does not mean the numbers themselves are perfects squares.

write the product in standard form: (3y-5)(3y+5)
Answer:
9y^2 - 25
Step-by-step explanation:
This is the product of the sum and difference of two squares:
(a - b)(a + b) = a^2 - b^2 (a formula well worth memorizing)
Therefore, (3y - 5)(3y + 5) = 9y^2 - 25, which is in standard form.
