Find the volume of the figure. Round to the nearest hundredth of a unit.

Answer:

In ten year you will be 10 years older than you are now and so will your brother. The 6 years difference will remain if no one dies.

Step-by-step explanation:

You are z years old

Your brother is 6 years younger than z years; z - 6 years

In 10 years time, you will be z + 10 years

Your brother will be z - 6 years + 10 years = z + 4 years

OR

In 10 years time, you will be z + 10 years

You brother is still 6 years younger than you, so is z + 10 years - 6 years = z + 4 years

The slope of line of best fit is 6.47887 which is approximately 6.5.

A line of best fit is a straight line that minimizes the distance between it and some data. The line of best fit is used to express a relationship in a scatter plot of different data points. It is an output of regression analysis and can be used as a prediction tool for indicators and price movements.

To calculate the slope of the equation, we need to solve for some parameters.

The equation of regression is given as

[tex]y = bX + a[/tex]

let's solve for the unknown parameters b and a.

[tex]b = \frac{SP}{SS_x}=\frac{3176.2}{490.24} = 6.47887 = 6.5[/tex]

The slope of the line of best fit is given as 6.5.

Answer:

$82.50

Step-by-step explanation:

82.5 times 0.7 = 57.75

doing 57.75 + 30% wouldn't work, so you have to increase the number (original price) being discounted until you get 57.75

also, the '0.7' is 70% which also means '30% off' because you took 30% away from the original price that was 100%

The number of mosquitoes will be increased by 5 inches of rain.

Maximum mosquito population = 25000

We are given the following in the question:

M(x) = 10x - x²

where M(x) denotes the number of mosquitos in millions and x denotes the amount of rainfall in inches.

To begin, we differentiate M(x) with respect to x, yielding

d(M(x)) /dx = d(10x - x²) /dx = 10 -2x

When we set the first derivative to zero, we get

d(M(x)) /dx = 0

10 - 2x = 0

x = 5

We get the same result when we differentiate M(x) with respect to x:

d²(M(x)) / dx² = -2

d²(M(x)) / dx² < 0

As a result of the double differentiation test, the maxima for M(x) occur at x = 5.

when the rainfall is 5 inches, the most mosquitoes are present.

Maximum mosquito population:

M(5) = 10(5) - (5)² = 25

As a result, the maximum number of mosquitos is 25000.

The cost of a t-shirt is $25, the cap costs $20 and the stuffed animal costs $15

Let t-shirts be represented by x, the cap is represented by y and stuffed animals are represented by z

Items purchased by family:

The total cost of the items was = $135

Equation: 4x+y+z=135--------(1)

Items purchased by couple 1:

2 t-shirts + 1 cap + 3 stuffed animals

The total cost of the items was = $115

Equation: 2x+y+3z=115------(2)

Items purchased by couple 2:

The measure of each angle are 36° and 144°

What is Supplementary angle?

Two angles are said to be supplementary if their sums total 180 degrees. A linear pair's two angles, like angles 1 and 2 in the illustration below, are always supplementary. But two angles don't have to be close to one another to be supplementary. In the following image, 3 and 4 are supplementary since their sums equal 180 degrees.

Let the provided angle be x, the supplementary angle be y.

y = x + 108 since x has 108° greater than y.

The total of the additional angles is 180°.

x + y = 180,

x + x + 108 = 180,

and x = 180 - 108.

2x = 72

x = 72/2

x = 36

Then,

y = x + 108

y = 36 + 108

y = 144

Consequently, the angles are 36° and 144°.

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

12b - 30

Factor out the common factor from the expression

So, we have

12b - 30 = 3 * 4b - 3 * 10

Factor out 3 from the expression

So, we have

12b - 30 = 3(4b - 10)

Factor out 3 from the expression

So, we have

12b - 30 = 6(2b - 5)

The expression above cannot be further simplified

This means that the expression has been completely factored and cannot be further factored

Because the prisms are stacked onto one another, they have a total volume of 320 cubic units

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following parameters

The volume of a prism is the prodict of its dimensions

This means that

Cube = Length^2

Cuboid = Base area * Height

So, we have the following equations

Shape 1 = a^3

Shape 2 =a^2b

Shape 3 =a^2c

Substitute the known values in the above equation

So, we have

Shape 1 = a^3 = 4^3 = 64

Shape 2 =a^2b = 4^2 * 6 = 96

Shape 3 =a^2c = 4^2 * 10 = 160

Add the above values

And most similar deliveries will be allowed since the likelihood of receiving a sample with much more than three damaged batteries is extremely low.

If at least three batteries fail to satisfy standards, the delivery would be approved.

This may be described as a binomial distribution, with n = 54 samples as well as a p = 0.03 probability of not satisfying the parameters of any battery.

If n ≤ 3 the package will be accepted.

The probability of this event is:

P(D ≤ 3) = P(D = 0) + P(D = 1) + P(D = 2) + P(D = 3)

P(D = k) = (n! ÷ (k!(n-k)!)) × [tex]p^{k}[/tex] × [tex](1 - p)^{n - k}[/tex]

P(D = 0) = (54! ÷ (0!(54)!)) × [tex]0.03^{0}[/tex] × [tex](0.97)^{54}[/tex]

P(D = 0) = 1 × 1 × 0.110

P(D = 0) = 0.110

P(D = 1) = (54! ÷ (1!(53)!)) × [tex]0.03^{1}[/tex] × [tex](0.97)^{53}[/tex]

P(D = 1) = 54 × 0.03 × 0.205

P(D = 1) = 0.3321

P(D = 2) = (54! ÷ (2!(52)!)) × [tex]0.03^{2}[/tex] × [tex](0.97)^{52}[/tex]

P(D = 2) = 1431 × 0.0009 × 0.205

P(D = 3) = (54! ÷ (3!(51)!)) × [tex]0.03^{3}[/tex] × [tex](0.97)^{51}[/tex]

P(D = 3) = 24804 × 0.000027 × 0.211

P(D = 3) = 0.141

We are given two box plots of a variable, for two different towns. Recall that the structure of a box plot is

where Q1 is the 25th percentile (or quartile 1), Q2 is the median and Q3 is the 75th percentile (or Quartile 3). This type of graphs tells us how the data is distributed, and more specially it can tell us how the data is spread across the different values the variable could take. So the way to analyze the spread from the graph is by considering the inter quartile range (IQR). This amount can be calculated by simply finding the difference between Q3 and Q1. If this range is really small, this would mean that the data is less spread and if this range is big, then this would mean that the data is more spread.

Using the given box plots, we can determine the following:

Town A: Q3 = 40, Q1 = 20, IQR = 40-20=20

Town B: Q3 = 45, Q1=35, IQR = 45-35 = 10

So, this would lead to option D.

Answer:

Tom is currently 5 and Bill is currently 11

Step-by-step explanation:

Let b = Bill's current age

Let t = Tom's current age

We have 2 unknowns so we need to equations to solve for this.

b = t + 6  

(b-3) = 4(t-3)  We have to subtract 3 from both Tom and Bill's current age

b- 3 = 4t - 12  Distribute the 4 and then substitute in t + 6 for b.

t + 6 -3 = 4t -12  Combine like terms

t + 3 = 4t -12  Subtract t from both sides of the equation

3 = 3t - 12  Add 12 to both sides of the equation

15 = 3t  Divide both sides by 3

5 = t  Tom is 5.  Since Bill is 6 years old, her is 11.

Check:

11 = 5+ 6

Three years ago, Tom would have been 2 and Bill would have been 8.  Bill is four times older than Tom.  2x4 = 8.

The number of breakfast Greg can eat from a box of cereal if he eats 1 1/2 servings for breakfast everyday is 8 breakfast.

Number of breakfast Greg can eat in a regular-sized box = A regular-sized box of cereal / servings of breakfast eaten everyday

= 12 ÷ 1 1/2

= 12 ÷ 3/2

= 12 × 2/3

= 24/3

= 8 breakfast

Cost of regular-sized box of cereal = $4.29.

Cost of one breakfast from a regular-sized box of cereal = Cost of regular-sized box of cereal ÷ Number of breakfast Greg can eat in a box

= $4.29 / 8

= 0.53625

Approximately,

$0.54 per breakfast

Number of breakfast Greg can eat in a family-sized box = A family-sized box of cereal / servings of breakfast eaten everyday

= 18 servings / 1 1/2

= 18 ÷ 3/2

= 18 × 2/3

= 36/3

= 12 servings

Therefore, the number of more servings of breakfasts Greg could eat from 1 family-sized box
