(I'm doing each individual question)​

Answer:

The answer is (Choice C)  It is just right.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water. Peggy made a 12-liter batch of iced tea with 90 tea bags. What will Kermit think of Peggy's iced tea? Choose 1 answer: (Choice A)  It is too strong. (Choice B)  It is too weak. (Choice C)  It is just right.

Now, to find which of the choice is correct.

So, we find first the unit rate of Peggy's iced tea bags per liter:

If, Peggy made a 12-liter batch of iced tea with 90 tea bags.

Then, Peggy would made a 1-liter batch of iced tea with = [tex]\frac{90}{12} =7.5\ tea\ bags.[/tex]

Now, to get the unit rate of Kermit's iced tea bags per liter:

If, Kermit made a 2 liter of iced tea with 15 tea bags.

Then, Kermit would made a 2 liter of iced tea with = [tex]\frac{15}{2} =7.5\ tea\ bags.[/tex]

Thus, the quantity of tea bags per liter is same of both Kermit and Peggy.

Hence, Kermit will think of Peggy's iced tea that it is just right.

Therefore, the answer is (Choice C)  It is just right.

Answer:

The answer is 13

Step-by-step explanation:

To find this we have find greatest common factor of 26 and 65 which turns out to be 13

To prove this answer we divide the number of scones to 13

26/13=2 scones of strawberry in each bag

65/13=5 scones of blackberry in each bag

2 and 5 will be found in each of the 13 bags.

Hope it helped.

The required greatest number of bags Jason can​ fill is 13.

Given as Jason has 26 strawberry scones and 65 blackberry scones. He wants to make as many identical bags of scones as possible. Each bag should have an equal number of strawberry scones and an equal number of blackberry scones.

The greatest common factor is defined as a group of the set of numbers that is the most considerable and greatest factor that all the numbers include of.

Here,
strawberry scones = 26
blackberry scones = 65
Taking the greatest common factor for the number of bags that can be filled with scones,
HCF [26, 65] = 13

Thus, the required the greatest number of bags Jason can​ fill is 13.

Answer:

Step-by-step explanation:

I think the data is repeated

The given data should be

41, 38, 36, 57, and 43

So, we want to find the absolute mean deviation, absolute here means we will discard the negative sign and make it possible

So, let find the mean of data

X~ = Σx / N

x is the given data

And N is the number of data given

X~ = (41 + 38 + 36 + 57 + 43) / 5

X~ = 215 / 5

X~ = 43

The mean is 43, so we and to find now the data given deviate from the mean.

X....... X-X~.......….|X-X~|

36..... —7............... 7

38..... —5.............. 5

41...... —2............... 2

43....... 0.........., ...0

57...... 14............. 14

So, the sum of the mean deviation is expected to be 0

ΣX-X~ = -7 -5 - 2 + 0 + 14 = 0

As expected

But the sum of the absolute mean is

Σ|X-X~| = 7 + 5 + 2 + 0 + 14 = 28

The mean deviation is given as

M•D = Σ|X-X~| / N

M•D = 28 / 5

The mean absolute deviation is 5.6 thousand dollars

This question is not correct

Correct Question:

The following data points represent the yearly salaries of high school cheer leading coaches in Dakota County (in thousands of dollars). 43, 41, 38, 36 , 57. Find the mean absolute deviation (MAD) of the data set.

Answer:

5.6 thousand dollars

Step-by-step explanation:

Mean Absolute Deviation is mean of or the average of absolute deviation of a set of data from it's central point.

We were given the following sets of data in thousands( the yearly salaries of high school cheer leading coaches)

43, 41, 38, 36, and 57

We would determine the Mean Absolute Deviation in the following steps:

Step 1

The first step is calculate the mean of the salaries

= (43+ 41 + 38+ 36+ 57) ÷ 5

= 215 ÷ 5

= 43

The mean of the salaries is 43 in thousand dollars.

Step 2

The second step would be to find the absolute difference of the values by subtracting the mean of the salaries from each of the salaries of the high school teachers , find the absolute values, after which we would sum up this absolute values together and divide by the number of the observed values

The number of observed values = 5

[|43 - 43| + |41 - 43| + |38- 43| + |36 - 43| + |57- 43| ]÷ 5

= 0 + |- 2|+ |- 5 |+|-7| + |-14| ÷ 5

= (0 + 2+ 5 +7 + 14) ÷ 5

= (28 ÷ 5) in thousand dollars

= 5.6 in thousand dollars

Therefore, the mean absolute deviation (MAD) of the data set in thousand dollars is 5.6.

Answer:

Log8(16)=4/3

Step-by-step explanation:

LogA(B) =C is same thing as A^C=B every single time

The given equation 16 = 8^4/3 can be written in logarithmic form as log8(16) = 4/3.

The given equation, 16 = 8^4/3, can be rewritten in logarithmic form as log8(16) = 4/3.

In logarithmic form, the base (8) becomes the subscript of the logarithm, the number being raised to the power (16) becomes the argument of the logarithm, and the result of the exponentiation (4/3) becomes the value of the logarithm.

Therefore, the equation 16 = 8^4/3 can be written as the logarithmic equation log8(16) = 4/3.

262 1/2 cubic feet

Step-by-step explanation:

The volume of a prism is (length)(width)(height).

Here we have

V = (6 1/4 ft)(14 ft)(3 ft)

Converting 6 1/4 ft to an improper fraction, we get 25/4.

Then the above product is V = (25 ft/4)(14 ft)(3 ft)  = 262 1/2 cubic feet

The volume of the rectangular prism is 262.5 cubic feet. Thus, the correct option is D.

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as,

V = L x W x H

A rectangular prism with a length of 6 and one-fourth feet, a width of 14 feet, and a height of 3 feet. Then the volume of the rectangular prism is calculated as,

V = (6 + 1/4) x (14) x (3)

V = 25/4 x 42

V = 1050/4

V = 262 + 1/2 cubic feet

V = 262.5 cubic feet

Thus, the correct option is D.

Answer:

He buys 8 desks and 6 chairs can i have branliest

Step-by-step explanation:

Set up a system of equations

desks = y chairs = x

x+y=14

125x + 515y = 4870

Eliminate,

-125x -125y = -1750

125x + 515 y = 4870

390 y = 3120

y = 8

substitute in 8

x + 8 = 14

x = 6

Answer:

Step-by-step explanation:

Let number of chairs be x and number of desks be y

Total number of chairs and desks = 14

x + y = 14   --------------(i)

Total cost  = $ 4870

125x + 515y = 4870 ------------(ii)

Multiply equation (i) by (-125).

(i)*(-125)          -125x - 125y = -1750

(ii)                    125x +515y = 4870    {Now add}

                                  390y = 3120

y = 3120/390

y = 8

Plug in value of y in equation 1

x + 8 = 14

x = 14 - 8

x = 6

Number of chairs = 6

Number  of desks  = 8

Step-by-step explanation:

From the attached table,

The range of group A = 5 - 0 = 5

The range of group B = 4 - 1 = 3

Difference in range is not equal to $1

The mode of A = 1

The mode of B = 3

Difference in mode is not equal to $1

The median of A = (1 + 2)/2 = 1.5

The median of B = 3

Difference = 3 - 1.5 = $1.5

The mean of A = 16/15 = 1.07

The mean of B = 40/15 = 2.67

The difference = $1.6

Since this is a right triangle, you have to follow the Pythagorean Theorem to solve this problem. The 2 sides-12 and 9 miles- are the known sides, and we have to find what is the value of c. The first Pythagorean Triplet(It is the pythagorean theorem, it just the triplets) is 3,4,5. If you multiple each of the numbers of any number, you will get another triplet. So, if you multiple 3,4, and 5 by 3, you will get 9, 12, and 15.

The first and last option.

Step-by-step explanation:

This is true because in the first chart, different y values correspond to different x values. In the other chart and option, the same y value corresponded to multiple x values - when this happens, it is not a function. This is why the first option is a function. In the last option, you gave an equation to a parabola. When graphed, the parabola opens downwards.  Only parabolas that open upwards or downwards are considered functions. Parabolas that open left or right are not considered parabolas. You can test whether or not a parabola is considered a function by conducting the "Vertical Line Test."

Answer:

To determine if they are functions or not, each y value needs to have only one x value. There should never be 2 values with the same x.

The first one is a function.

The second one is not a function because there are two coordinates that have -1.

The third on is not a function because there are two of them that have 0.

The fourth one is a function because when listing the inputs and outputs, there are different x values for each y value.
