the answer is 49/40

Answer:

I think the answer is x is 16 and y is 20? I could be wrong tho

Step-by-step explanation:

First, subtract -7 from -1 to get 8.

Then, add the 12 and you get 16 for x.

First, subtract 7y from 9x to get 2y

Then, add 4 to get 20 for y.

Answer:

A. 4.5

Step-by-step explanation:

Given:

20, 12, 27, 23, 18, 20, 30, 26

Mean = 22

Required:

Calculate the Mean Absolute Deviation (M.A.D)

Since, we have the mean; we start calculating M.A.D by subtracting the mean from each data

20 - 22 = -2

12 - 22 = -10

27 - 22 = 5

23 - 22 = 1

18 - 22 = -4

20 -22 = -2

30 - 22 = 8

26 - 22 = 4

The we find absolute value of the result above

|-2| = 2

|-10| = 10

|5| = 5

|1| = 1

|-4| = 4

|-2| = 2

|8| = 8

|4| = 4

Lastly, we calculate the mean of the above to give M.A.D

[tex]M.A.D = \frac{2 + 10 + 5 + 1 + 4 + 2 + 8 + 4}{8}[/tex]

[tex]M.A.D = \frac{36}{8}[/tex]

[tex]M.A.D = 4.5[/tex]

Option A is correct.

The value of the mean absolute deviation is 4.5 hours if the mean of the data set is 22 hours, option first is correct.

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance is known as the MAD.

We have data:

20, 12, 27, 23, 18, 20, 30, 26

Mean of the data X = 22 hours

∑(x - X) = 36

MAD = 36/8 = 4.5 hours

Thus, the value of the mean absolute deviation is 4.5 hours if the mean of the data set is 22 hours.

Answer:

Step-by-step explanation:

l = 5 in

w = 5 in

h = 12 in

Surface area of rectangular prism = 2*(lw +wh + hl)

 = 2*(5*5 + 5*12 + 12*5)

  = 2*(25 +60 +60)

  = 2*145

  = 290 in²

Answer:

OA = 19.58

Step-by-step explanation:

If we draw the segments OA and OC, we will have an isosceles triangle OAC.

With the property of inscribed angles and central angles that are related to the same arc of the circunference, we have:

mAOC = 2 * mABC

mAOC = 2 * 50 = 100°

As the triangle OAC is isosceles, we have that mOAC = mACO.

Knowing that the sum of internal angles of a triangle is 180°, we have:

mACO + mOAC + 100 = 180

2 * mACO  = 80

mACO = 40°

Now, using the law of sines, we have:

OA / sin(ACO) = AC / sin(AOC)

OA / 0.6428 = 30 / 0.9848

OA = 30.463 * 0.6428 = 19.58

Answer:

the answer is 40

Step-by-step explanation:

you have to multiply 8x10=80 divied by 20 which equal 40

The cups of juice that Yesenia buys are:

Step-by-step explanation:

To solve this, you need to know the conversión below:

Now the paragraph mentions that Yesenia buys 1 quart of juice (that refers to a quart of gallon), then, having the conversion above we can operate with a rule of three:

Solving this we have:

In the first purchase, Yesenia actually buys 4 cups (that is the same to 1 quart of gallon), next she buys one eighth, then we operate again with the first conversion but using this new quantity:

Solving this we have:

By last, we add every purchase:

Answer:

D; y= 2.52x

Step-by-step explanation:

You half $5.04 (the cost of two lbs of cranberries) and get $2.52 then multiply by x (the lbs.) equals y the cost of all the lbs. of cranberries.

Therefore getting the equation of y= 2.52x

Answer: y=2.52x

Step-by-step explanation:

if you take any of the statements you can calculate it.

Let "x" be pounds, and "y" the total cost of x pounds.

2x=5.04

Divide by 2

x=5.04/2

x=2.52

The misleading one or the one that miss out information.

"Mean" Means the middle number of the total number. Like add all the number in the graph and divide by 2

Attached is the image of the entry way

Step-by-step explanation:

Given that each unit length represents 1 foot.

To find the area of the shape shown in the attached image, we need to divide the shape into two parts at about 4 ft from the bottom.

The top shape is a trapezoid of base length 4 ft, top length 7 ftand height 5 ft, while the bottom shape is a parallelogram with one side equal to 4 ft and height 4 ft

Area of a Trapezium = 1/2 × (a+b)h

a = 4ft, b= 7ft, h = 5ft

Substituting the values;

Area of trapezoid = 1/2 × (7 + 4)x 5

Area of trapezoid = 27.5 ft^2

Area of a parallelogram = length × height

Length = 4 ft, height = 4 ft

Substituting the values;

Area of parallelogram = 4 x 4

Area of parallelogram = 16 ft^2

Total area = area of trapezium + parallelogram

Total area = 27.5 + 16 = 43.5 ft^2

Cost per square foot = $ 1.85

Total cost = cost per square foot × area

Total cost = $1.85 per square foot × 43.5ft^2

Total Cost = $80.48

Answer:

Sal will pay $ 80.48  to tile his entryway.

Step-by-step explanation:

Separate the entryway into simpler shapes: a trapezoid and a parallelogram.

Find the area of the simpler figures. Count units to find the dimensions.

Trapezoid

A =   1/ 2

h(b₁ + b₂)

A =   1/ 2

(5)(4 + 7)

A =   1/ 2

(5)(11)

A = 27.5

The area of the trapezoid is 27.5 ft  

2 .

Parallelogram

A = bh

A = 4 · 4

A = 16

The area of the parallelogram is 16 ft  

2 .

Find the area of the entryway.

A = 27.5 + 16

A = 43.5

The area of the entryway is 43.5 ft  

2 .

Calculate how much Sal will pay to tile his entryway.

Area · Cost per foot =  Total Cost

43.5 · $1.95 =  $84.83

Sal will pay $84.83 to tile his entryway.

Answer:

The probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble =[tex]\frac{7}{34}[/tex]

Probability of selecting no red marble = [tex]1-\frac{7}{34}=\frac{27}{34}[/tex]

Now replacing it one marble is drawn again

So, Probability of getting white marble [tex]=\frac{9}{34}[/tex]

So,the probability of selecting a marble that is not red, replacing it and then one that  is white =[tex]\frac{27}{34} \times \frac{9}{34}=0.2102[/tex]

Hence the probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Answer: triangular pyramid

Step-by-step explanation: The net shown here is composed of 3 triangular faces and 1 triangular base. The triangular faces tell us that the figure is a pyramid and the triangular base tells us that it's a triangular pyramid. You can always check your answer by tracing the net, cutting it out, and folding it to see what kind of a figure is formed.

Answer: N= 135, M=45.

Step-by-step explanation:The formula to find the degree inside of a shape is: (n-2)180. This is an octagon, so it has 8 sides, plug this in for n.

8-2 * 180

1080                              divide by 8 to get the value of n

n=135

The formula for an angle outside of the shape is:

360/n   n is still eight, so plug this in for n

360/8

m=45

Answer:

n = 135 degrees ( ° ) ,

m = 45 degrees ( ° )

Step-by-step explanation:

* Sorry I didn't answer this before *

1. In this figure we can see that this visual is a representation of an octagon, provided it's 8 sides.

2. Knowing this, let us split this figure into triangle 180 degrees each ⇒ compute the total interior angles in degrees.

3. If you were to draw lines from one vertex to any other non-adjacent vertices, it would be that 6 triangles are formed.

4. One triangle ⇒ 180 degrees ( ° ) so that this octagon ⇒ 180° * number of triangles, or ⇒ 180 * 6 = 1080°

5. Knowing that this shape is a regular polygon, all angles are congruent such that if x represents one interior angle ⇒ 8x = 1080, ⇒ x = 135°. As n acts as one of the interior angles in this figure ⇒ n = 135 degrees ( ° )

6. Now through supplementary angles, the interior angle adjacent to angle m would form a linear pair, adding to 180°.

7. This would mean that m + interior angle = 180, and as all interior angles were found to be 135 degrees ⇒ m + 132 = 180 ⇒ m = 45 degrees ( ° )

Answer:I think one is x

Step-by-step explanation:

Answer:

x = 10 units

Step-by-step explanation:

The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).

Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units

If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)
