In your class, 7 students do not receive a weekly allowance,5 students receive $3 , 7 students receive $5, 3 students receive $6 , and 2 students receive $8 .

a. What is the mean weekly allowance?

The mean weekly allowance is______
dollars.

Answers

Answer:

The mean weekly allowance is $3.5

Step-by-step explanation:

to find the average, we add up everything, and divide it by how many students there are.

0, 0, 0, 0, 0, 0, 0, 3, 3, 3, 3, 3, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 8, 8 <- this is what you add up

you get 84.  Then you divide this amongst all of the students.

7+5+7+3+2=24

84/24 = 3.5

Please give brainliest!

Hope this helps :)

the answer is $3.5
you multiply the amount of money with the amount of students then add it all together after you get your total ($84) you add the number of students including those who had no money (24) you then divide 84/24 your answer is $3.5

A tank can be filled in 22 and a fifth minutes. What fraction of it will be filled in 21 min

Answers

Answer:

I believe the answer is about 95 percent.

Step-by-step explanation:

The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...

22 1/5 over 100 = 21 over x

Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer

What I just wrote is the rule of proportions

Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

95% of the tank should be filled

A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions 18 inches by 9 inches. What is the height of the pyramid? 4 in. 12 in. 24 in. 36 in.

Answers

Answer: 4 inches

Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4

Based on the calculations, the height of this pyramid is equal to: D. 36 inches.

Given the following data:

Volume of pyramid = 1,944 cubic inches.Dimensions of rectangular base = 18 inches by 9 inches.

How to calculate the height of this pyramid?

Mathematically, the volume of a pyramid is calculated by using this formula:

Volume = 1/3 × b × h

Where:

b is the base area.h is the height.

For the base area, we have:

Base area = length × breadth

Base area = 18 × 9

Base area = 162 square inches.

Substituting the given parameters into the formula, we have;

1,944 = 1/3 × 162 × h

1,944 = 54h

h = 1,944/54

Height, h = 36 inches.

Every day, the Sandoval Family Restaurant serves 5/6 of a bottle of soda to their customers. How many days will 7 1/2 bottles of soda last?

Answers

Answer:

9 days

Step-by-step explanation:

1 day: 5/6        2 days:  10/6       3 days:   15/6        4 days:  20/6   5  days: 25/6

6 days:  30/6        7 days:  35/6         8 days:  40/6       9 days: 45/6

If you divide 45 and 6 by 3 you get 15/2.  If you put 15/2 into a mixed number you would get 7 1/2.  So 9 days would be your answer.

Answer:

7 1/2 bottles will last 9 days

Step-by-step explanation:

To answer this, divide '7 1/2 bottles' by '5/6 bottle per day:"

 7 1/2 bottles

-----------------------

 5/6 bottle/day

The unit "bottle"/"bottles" cancel, and so we are left with

 7 1/2 day

-------------------  and this is equivalent to   15 days/2  divided by 5/6 OR

    5/6

 15 days/2 times 6/5:

15(6)

--------- days = 18/2 days = 9 days (answer)

7 1/2 bottles will last 9 days.

Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.

To find x, we can use some facts from geometry and trigonometry.

• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.

• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.

• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.

• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have

tan(70°) = 12 / (x/2)

and solving for x gives

tan(70°) = 24/x

x = 24/tan(70°)

x = 24 cot(70°) ≈ 8.7

Then the total area of the nonagon is

54x = 54 • 24 cot(70°) ≈ 471.7

A weather forecast states that there is a 20% probability of rain on each of the next 3 days.


Complete the description of a simulation you could perform using random numbers to find the experimental probability that it will not rain on any of the next 3 days.



To simulate a 20% probability of rain over 3 days, let
of 10 numbers represent a day with rain. So,
of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.

Answers



answer: The experimental probability that it will not rain on any pf the next 3 day is 64/125


The probability of raining is 20%
Hence, the probability that there will be no rain, is (100-20) = 80%
The probabilty that there is no rain on the first day is 80/100 = 4/5


Hence, the required probaility is (4/5)3 = 64/125

The cost of a cleaning service includes labor and supplies. Supplies are 30% of the total cost. The cost of supplies for a certain cleaning service is $54.

What is the total cost of the cleaning service?

Enter your answer in the box.

Answers

Answer:

The total cost of the cleaning service is $180

Step-by-step explanation:

We have, 30% × x = 54

or,

30/100 × x = 54

Multiplying both sides by 100 and dividing both sides by 30,

we have x = 54 × 100/30

x = 180

If you are using a calculator, simply enter 54×100÷30, which will give you the answer.

A. 26
B. 3
C. 77
D. 416

Answers

I think it b to because the chances of it being 26 if their was only 9 truck there probably won’t be a crazy amount more.
The answer is B because 9/36 is a 1/4 chance, a 25%. If another parking lot for example also had 36 total and there were 3 trucks, it would be about a 10%. If there were 26 trucks, that would be like a 70% chance. 10% is closer to 25 than 75 so I’d say B!

Area: 7,089ft
Perimeter: 380ft

Answer:

The perimeter is 380 ft^2.

Step-by-step explanation:

To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.

To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.

Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

Dilated ∆ ABC about point C with a scale factor of 2

Translate ∆ A' B' C' to the 0.5 by 2 units.

Determining the scale factors of a triangle

From the triangles given, ∆ DEF was dilated to ∆ ABC

The dilated triangle is = ∆ ABC

To find the scale factor uses for the dilation of the triangle, the length of the triangle AC and DF are considered.

AC from the scale= -2 -(-7)

= 7-2= 5

DF= 9-6.5

= 2.5

Therefore the scale factor = 5/2.5 = 2

And since the scale factor of dilation is 2 this means that ∆ A' B' C' can be translated to the 0.5 by 2 units.
