What’s the greatest mad
Answer: Jason's team.
Step-by-step explanation: When finding the MAD, you need to find the mean of the data, which they said is 10. The next step is to subtract numbers from the data from the mean, which is 10 for all three dot plots. For example, for Jason's team, we need to subtract all the 7's, 8's, 11's, 12's, and 13's, because those are the only parts of the plot with data. Let's try subtracting 7 - 10. The answer is -3, but we need to make it positive, because that's how data works, so it's actually 3. You keep doing this for all three plots, which is provided below:
Jason's Team: 3, 3, 2, 2, 2, 1, 2, 3, 3, 3.
Hannah's Team: 3, 2, 2, 1, 0, 0, 1, 1, 3, 3.
Dion's Team: 1, 1, 1, 1, 0, 0, 0, 0, 1, 3.
Now, the next step is adding all these values and dividing it by ten, since that's how many numbers there are for the data.
Jason's Team MAD: 2.4.
Hannah's Team MAD: 1.6.
Dion's Team MAD: 0.8
As you can see, Jason's Team has the greatest MAD, which is your answer.

Crop yield is the ratio of the number of bushels harvested to the number of acres used for the harvest. This year, the harvest at a farm was 9,396 bushels of soybeans, resulting in a crop yield of 40. 5 bushels per acre. To the nearest whole acre, how many acres were harvested? 232 acres 252 acres 285 acres 295 acres.
The total harvested area is 232 acres .
To determine the number of acres harvested, we simply have to divide the bushels of soybean by the crop yield.
Mathematically we can write it as,
What is the formula for the total land area?The total land area = bushels of soybean / bushels per acre
Substituting the known values,
[tex]Total land area = 9396 / 40.5 = 232[/tex]
Therefore, 232 acres were harvested.

Can someone work this one out with me please
Answer:
46°
Step-by-step explanation:
Since the side mn is tangent, the angle in M is a right angle. The sum of internal angles needs to add to 180°, so subtacting you're left with 46°
Hi there!
Since MN is tangent to Circle K, we know that MK and MN are PERPENDICULAR.
Therefore, m∠M = 90°.
Since we now know two angles in the right triangle, we can solve for m∠K knowing that angles in a triangle sum up to 180°.
180° = ∠M + ∠N + ∠K
180° = 90° + 44° + ∠K
Combine like terms:
180° = 134° + ∠K
Subtract:
180° - 134° = ∠K
∠K = 46°
If f(x)=2^x is translated 3 units up and 4 units to the left what is the equation for the transformed graph?
Answer:
Step-by-step explanation:
[tex]f(x) = 2^{x}[/tex]
translate 3 units up will change the y coordinate so will add 3 to y or f(x)
[tex]f(x) = 2^{x} +3[/tex]
translate 4 units to the left will change the x coordinates so will add 4 to the x to move towards left
[tex]f(x) = 2^{x+4} +3[/tex]
An electrician charges $55 an hour for labor and an initial fee of $95. The total cost c equals 55 times the number of hours x plus 95. Enter an equation for the relationship and use the equation to complete the table.
Answer:
C = 55h + 95
Step-by-step explanation:
That is the equation, I can't see a table but I'm assuming you would be given hours worked, so plug that in for the h value and solve to get a cost in $.
For example, if he worked for 2 hours then
C = 55(2) + 95
C = 110 + 95
C = $205

What is the value of x
Answer: 37
Step-by-step explanation:
74=2x
37=x
You are trying to get X by itself. Since it's 2x usually you would multiply it but in this case, divide it by itself into both sides so 74 divide 2 equals 37. If you know the order of operations then reverse it.
I'm just confused about how the answer choices are only 108 and 18.
Answer:
[tex]\huge\boxed{\sf x = 37}[/tex]
Step-by-step explanation:
Since, vertically opposite angles are equal:
74 = 2x
Divide 2 to both sides
74 / 2 = x

f(x)=x^3-7/x
f(x)=|-x|
f(x)=25-x^3
f(x)=72-x^4
By using the definition of even and odd functions, we will see that:
a) oddb) even.c) neitherd) even.What is an odd and an even function?A function f(x) is even if:
f(x) = f(-x)
And the function is odd if:
f(-x) = -f(x).
Now let's check it for all the given functions.
a) f(x) = x^3 - 7/x
-f(x) = -x^3 + 7/xf(-x) = (-x)^3 - 7/(-x) = -x^3 + 7/xSo this function is odd.
b) f(x) = |-x|
-f(x) = -|-x|f(-x) = |-(-x)| = |x| = |-x|This function is even.
c) f(x)=25-x^3
-f(x) = -25 + x^3f(-x) = 25 - (-x)^3 = 25 + x^3This function is neither odd nor even.
d) f(x) = 72-x^4
-f(x) = -72 + x^4f(-x) = 72 - (-x)^4 = 72 - x^4 = f(x)This function is even.

A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in feet per second, at which the cyclist travels?
PLEASE
Answer:
[tex]\boxed{33.5 \ \text{feet/second}}[/tex]
Step-by-step explanation:
To find the unit rate, we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.
Note: Since the cyclist travels at a constant rate, unitary method can be used.
[tex]\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}[/tex]
[tex]\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}[/tex]
Divide both sides by 25:
[tex]\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}[/tex]
[tex]\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}[/tex]

EXPLAIN YOUR ANSWER
SHOW YOUR WORK
Answer:
C) [tex]y=-0.5x+8[/tex]
Step-by-step explanation:
Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.
All the given options for the line of best fit are linear equations.
Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above and below the line.
Linear equation: [tex]y=mx+b[/tex]
(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)
From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 8. So this suggests that options C or D are the solution.
We can also see that the slope (gradient) of the line of best fit is approximately -0.5 (as the rate of change (y/x) is -1 unit of y for every +2 units of x).
Therefore, C is the solution, and the closet approximation to the line of best fit is [tex]y=-0.5x+8[/tex]
Carrie makes 27 liters of lemonade 8 people share their lemonade leafly
Answer: 3.375
Step-by-step explanation:
27 divided by 8 equals 3.375
Assuming each of the 8 person gets equal share of the whole 27 litre lemonade, the amount of lemonade each person would get is 3.375 litres.
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b = a[/tex] divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
For this case, we're specified that:
Amount of lemodnade Carrie made = 27l itresNumber fo people in which this lemonade will be divided = 8Assuming that they all get equal share and we want to know the amount each person will get, we get:
Amount of lemonade each of those 8 person would get = 27 litres / 8
[tex]27/8 = 3.375[/tex]
Thus, each person gets 3.375 litres of the considered lemonade.

Which expression represents the correct form for the quotient and remainder, written as partial fractions, of StartFraction 7 x squared minus 40 x + 52 Over x squared minus 6 x + 9 EndFraction?
Answer:
[tex]A + \frac{B}{x-3} + \frac{C}{(x-3)^{2} }[/tex]
Step-by-step explanation:
First, because the degree of the numerator is the same as the degree of the denominator, this fraction needs simplified further by long division. Upon simplification, the rational expression is [tex]7+\frac{2x-11}{x^2-6x+9}[/tex].
Next, the denominatior needs factored in order to split up the second part of the simplified expression into two different partial fractions. Such factorization yields us, [tex](x-3)^{2}[/tex].
Finally, we have all of our necessary information to set up all of our partial fractions.
This gives us [tex]A + \frac{B}{x-3} + \frac{C}{(x-3)^{2} }[/tex], which is our answer.
