Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

135.6 ft²

Step-by-step explanation:

            In the triangular pyramid, base is an equilateral triangle, and the lateral faces are congruent triangles. So, to find the surface area add the area of base triangle with the area of 3 lateral triangles.

     a) Base area of pyramid:

            b= 8 cm

            h = 6.9 cm

         \(\boxed{\bf base \ area \ of \ pyramid = \dfrac{1}{2}*b*h}\)

                                                 \(= \dfrac{1}{2}*8*6.9\\\\=4*6.9\\\\= 27.6 \ ft^2\)

b) Area of one lateral surface area of pyramid:

                  b = 8 cm

     slant height = l = 9 cm

      \(\boxed{\text{\bf area of one lateral surface area of the pyramid = }\dfrac{1}{2}b*l}\)

                                                          \(\sf = \dfrac{1}{2}*8*9\\\\= 4 * 9\\\\= 36 \ ft^2\)

c) Lateral surface area of the pyramid = 3 * area of one lateral surface area of pyramid

                                                              = 3 * 36

                                                              = 108 ft²

d)TSA of pyramid:

      \(\boxed{\text{\bf Total surface area of pyramid = base area + lateral surface area}}\)

                                                         = 27.6 + 108

                                                        = 135.6 ft²

Answer:

C. The mean increases by 1.4°.

Step-by-step explanation:

if you count the number of numbers in the set {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} it is 12 numbers.

The formula for mean is,  \(mean=\frac{sum- of- the- terms}{number-of-terms}\)

so if you add all the numbers here →,  {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57}  you get a sum of 965.

Now 965 ➗12= 80.4166666667

If 98 is added we add 98 to 965 and get 1063.

That also means an additional number is being added so 12+1 = 13.

Now, 1063➗13= 81.7692307692

Ok now we approximate, 80.4166666667 is about 80.4 and 81.7692307692 is about 81.8.

Now we subtract 81.8-80.4 and get 1.4.

It was an increase of 1.4 in the mean so the answer is C.

Relative minimum: The coldest temperature outside the car was -4°C.

The negative interval is: between the 110th and 170th kilometers, the outside temperature was below zero.

The increasing interval was: over the first 50 km, the temperature outside the car got warmer.

The relative minimum or maximum of a graph is:

A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a "peak" in the graph).

A relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a "bottom" in the graph).

Thus, the relative minimum of the graph is -4°C.

The negative interval is between the 110th and 170th kilometers, the outside temperature was below zero.

The increasing interval was over the first 50 km, the temperature outside the car got warmer.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

Solve for x: 22x + 54 = -20 + 60x

Solve for x: 8 + 9.8x + 9 = 3.8x - 16 + 3.8x

Solve for x: -2x - 10 = -14x - 7

Step-by-step explanation:

First step is to Combine the like terms, which means to subtract 60 from 22 which will equal -38x+ 54 = -20 + x

Next you will add 20 with 54 and -20 which will give you -38x+ 74 = x

Finally you have to find x so swap out -38x with x and solve 74 + x = -38 and that will be your answer. Please do the same for the next two problems and you will be good to go!

Using the given values, we can calculate the volume for each option:

Option 1:

Radius = 2.5 inches

Height = 6 inches

Volume = 3.14 x (2.5²) x 6 = 117 in³

Option 2:

Radius = 1.5 inches

Height = 3 inches

Volume = 3.14 x 1.5² x 3 = 21.195 in³

Option 3:

Radius = 2 inches

Height = 2.25 inches

Volume = 3.14 x 2² x 2.25 = 28.26 in³

Add 5n to both sides

3m = 11 + 5n ( divide both sides by 3 )

m = \(\frac{11+5n}{3}\) , thus

Answer:

x = 1/3

Step-by-step explanation:

1. Remove  parenthesis.

3x −5/3 = 11x −5

2. Multiply both sides by 33.

3x -5 = 33x -15

3. Subtract 3x3x from both sides.

-5 = 33x -15 -3x

4. Simplify  33x-15-3x33x−15−3x  to  30x-15.

-5 = 30x - 15

5. Add 15 to both sides.

-5 + 15 = 30x

6. Simplify  -5+15 to  10.

10 = 30x

7. Divide both sides by 30.

10/30 = x

8. Simplify  10/30 to 1/3

1/3 = x

9. Switch sides.

x = 1/3
