Answer:

Volume of the shaded space = 4480.0 yd³

Step-by-step explanation:

Volume of the shaded space = Volume of cuboid - Volume of Pyramid placed inside

Volume of cuboid = Length × Width × Height

                              = 28 × 12 × 20

                              = 6720 yd³

Volume of pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Height})[/tex]

                                = [tex]\frac{1}{3}(28\times 12)(20)[/tex]

                                = 2240 yd³

Volume of the shaded space = 6720 - 2240

                                                  = 4480.0 yd³

Answer: The mean is 6.

Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.

Answer:

6.

Step-by-step explanation:

First you take the data on the dot plot, and write the numbers down from least to greatest.

The data set:

2,3,6,6,7,8,8,8

Now that you have the data reordered in a easier way to read, add up all the numbers that you got from the dot plot.

2+3+6+6+7+8+8+8=48

Next we count all the number in the data set we made.

2,3,6,6,6,7,8,8,8 = 8

The amount of numbers in this data is 8.

Lastly we then divide 48 by 8.

48/8= 6

So your answer is 6!

Answer:

[tex]6(7) + 7(11)[/tex]

Step-by-step explanation:

Given

The expression is:

[tex]6a + 7b[/tex]

[tex]a = 7[/tex]

[tex]b = 11[/tex]

Required

The corresponding expression when the values are substituted for the variables

We have: [tex]6a + 7b[/tex]

Substitute [tex]a = 7[/tex]

So, the expression becomes:

[tex]6(7) + 7b[/tex]

Substitute [tex]b = 11[/tex]

So, the expression becomes:

[tex]6(7) + 7(11)[/tex]

Answer:

A) [tex]f^{-1} (x)=\frac{5x+3}{2}[/tex]

Step-by-step explanation:

[tex]f(x)=\frac{2x-3}{5}[/tex]

[tex]y=\frac{2x-3}{5}[/tex]

[tex]x=\frac{2y-3}{5}[/tex]

[tex]\frac{5x+3}{2} =y[/tex]

[tex]y=\frac{5x+3}{2}[/tex]

So option (A)

Answer:

a) 15.866%

b) 0.68268

Step-by-step explanation:

The scores for all the sixth graders at Roberts School on a statewide test are normally distributed with the mean of 76 and a standard deviation of 10.

We solve the above question using z score formula

= z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 76

σ is the population standard deviation = 10

a) What percent of the scores were below 66?

x < 66

Hence,

z = 66 - 76/10

z = -1

Probability value from Z-Table:

P(x<66) = 0.15866

Converting to Percentage =

0.15866 × 100

= 15.866%

b) What is the probability that a student earned a score between 66 and 86?

For x = 66

Hence,

z = 66 - 76/10

z = -1

Probability value from Z-Table:

P(x≤ 66) = 0.15866

x = 66 = 0.15866

For x = 86

Hence,

z = 86 - 76/10

z = 1

Probability value from Z-Table:

P(x≤ 86) = 0.15866

x = 66 = 0.15866

Probability value from Z-Table:

P(x = 86) = 0.84134

The probability that a student earned a score between 66 and 86 is calculated as:

P(x = 86) - P(x = 76)

= 0.84134 - 0.15866

= 0.68268

Answer:

150 cm2

Step-by-step explanation:

one square would simply be base x height our base is 5 and height is 5 so i multiply that and get 25 since this is a cube all sides are equal so I will simply just multiply 25 by the number of sides since a cube has 6 sides our equation to get the answer would be 25 x 6 = 150 so 150 is our answer! Hope this is a good explanation! Have a good day!

Answer:

The answer is c

Step-by-step explanation:

5x+3y=19

multiply x 2: 10x+6y=38

2x-4y=-8

multiply by -5: -10x+20y=40

now you can add the two equations:

                    10x+6y=38

                    -10x+20y=40

add equations 0x+26y=78

                               Y=3

Answer:

56°

Step-by-step explanation:

180 = 40 + (2x) + (3x)

180 - 40 = 40 + 5x - 40

140/5 = 5x/5

x = 28

2(28)

= 56

Answer:

m∠A = 56°

Step-by-step explanation:

A triangle contains 180°. So

180 - 40 = 140

2x + 3x = 140

5x = 140

x = 28

Now, plug in the value for x.

2(28) = 56

Check your work.

40 + 56 + 84 = 180

Answer:

$(a + b) + cn cent

Step-by-step explanation:

Given :

Fixed charge = $a

Rent of a meter = $b

Charge per unit of electricity = c cents

The total cost of using n units of electricity :

For n units of electricity ;

Fixed charge is paid once

Meter rent is paid once

The cost of electricity = (number of units * cost per unit) = (n * c) = nc cents

Total cost of n units of electricity :

$(a + b) + cn cent

Answer:

1/10.

Step-by-step explanation:

The probability of getting an even card out of 10 cards numbered 1 - 10 is 1/2. The even numbers available are 2, 4, 6, 8, and 10 while the odd ones available are 1, 3, 5, 7, and 9. So half the outcomes could come out even.

The probability the second card is less than two is 1/5 (2/10 simplified). Since there are 10 cards with numbers 1-10, only two cards will have numbers less than 3, 1 and 2.

To find the total probability, multiply the two. (1/2) * (1/5) = 1/10. There is a 1 out of 10 chance that the first card is even and the second card is less than 3.
