The statement that a box plot graphically shows the 10th and 90th percentiles is False.

A box plot is a graphical representation of a data set that displays key summary statistics, such as the median, quartiles, and potential outliers. It is also known as a box-and-whisker plot. The statement that a box plot graphically shows the 10th and 90th percentiles is False.

In a box plot, the box represents the interquartile range (IQR), which contains the middle 50% of the data. The lower and upper quartiles, representing the 25th and 75th percentiles respectively, are marked by the lower and upper edges of the box. The median, or the 50th percentile, is represented by a line or another symbol within the box.

While the box plot provides information about the spread of the data, it does not directly show the 10th and 90th percentiles. However, by extending the whiskers, which represent the range of the data, you can get a sense of the minimum and maximum values. The whiskers typically extend to the most extreme data points that are within a certain range, such as 1.5 times the IQR.

So, in summary, a box plot does not explicitly show the 10th and 90th percentiles, but it does provide information about the range of the data, which can give you an idea of the overall distribution.

Using the volume for rectangular prisms, the volume of the chimney is: 216 in.³.

The volume of a rectangular prism = (length)(width)(height).

The Chimney in Emily's house is a composite solid consisting of two rectangular prism. To find the volume, we have to decompose the figure into two rectangular prisms. Then solve for the volume of each before finding the total volume.

Volume of the bigger rectangular prism = (length)(width)(height) = (4)(4)(12)

Volume of the bigger rectangular prism = 192 in.³

Volume of the smaller rectangular prism = (length)(width)(height) = (4)(2)(3)

Volume of the smaller rectangular prism = 24 in.³

The volume of the chimney = volume of the two rectangular prism

The volume of the chimney = 192 + 24

The volume of the chimney = 216 in.³

Answer:

1/3 and -1/2

Step-by-step explanation:

You can use the factoring method to identify the solutions of x

6x^2+x-1

2 numbers have to multiply to 6 and subtract to 1 because x is the same as 1x

So, you get 3x and 2x

since you know that -1x1 is -1 you will get

(3x-1)(2x+1)=0

Now, since (3x-1) and (2x+1) multiply to get 0, if either (3x-1) or (2x+1) is 0 the statement will be valid

3(1/3)-1=0

2(-1/2)+1=0

a) The cube-shaped sculpture has edges that are 4 ft long, so the volume of the sculpture is 4^3 = 64 ft^3. The density of the marble is 170 lb/ft^3, so the weight of the sculpture is 64 ft^3 * 170 lb/ft^3 = 10,880 lb.

Since the sculpture weighs more than 10,000 lb, the pedestal should not be able to support it. The sculpture would require a pedestal that can support more than 10,000 lb.

b) The density of the marble is determined by the mass of the marble per unit volume. If the sculpture was half the size, it would have half the volume, but the same mass. So, the density of the marble would not change.

To estimate the number of sticks of butter needed to fill an empty bathtub, we can use the Fermi process.

First, we need to find the volume of the bathtub. A rectangular prism has a length of 60 inches, a height of 40 inches and a width of 20 inches. So, the volume of the bathtub is 604020 = 48000 cubic inches.

Next, we need to find the volume of a stick of butter. A stick of butter has a length of 4 inches, a width of 2 inches, and a height of 2 inches, so the volume of a stick of butter is 422 = 16 cubic inches.

Finally, we can divide the volume of the bathtub by the volume of a stick of butter to find the number of sticks of butter needed to fill the bathtub:

48000/16 = 3000 sticks of butter.

We can estimate that it would take around 3000 sticks of butter to fill an empty bathtub with the given measurements.

This exercise has nothing to do with inverse operations.

Let L represent the number of lawns Tyler mows, and D the number of dogs he walks.

If he earns $20 for each lawn mown, then mowing L lawns earns him $20L. For example, if he mows 1 lawn, he gets $20. If he mows 2 lawns, he earns $40. And so on.

The same could be said about dog-walking. If he earns $15 for each walk, then walking D dogs is worth $15D. For example, if he walks 1 dog, he gets $15; for 2 dogs, $30; and so on.

If after a week he has earned a total of $260, then

20L + 15D = 260

which can optionally be simplified a bit by dividing through both sides by 5 to get

4L + 3D = 52

Since you mentioned "inverse", I suspect you interpreted the question as asking how many lawns Tyler mowed and how many dogs he walked. This is impossible, you cannot determine exactly how many lawns or dogs were involved. But there are only 4 ways this can happen, since L and D must be counting numbers.

D = 4, L = 10

D = 8, L = 7

D = 12, L = 4

Question:

Davis wants to pour 5 gallons of punch into ½ gallon jugs How many jugs will he need?

A. 2½

B. 5½

C. 10

D. 15

Answer:

Number of jugs = 10

Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

Step-by-step explanation:

David has 5 gallons of punch that he wants to pour into jugs.

The capacity of 1 jug is ½ gallon.

The required number of jugs may be found as

Number of jugs = gallons of punch/capacity of jug

For the given case, we have

Gallons of punch = 5

capacity of jug (in gallons) = ½ = 0.5

So, the required number of jugs is,

Number of jugs = 5/½

Number of jugs = 5/0.5

Number of jugs = 10

Therefore, Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

The derivative of y = ecosh(4x) is y' = 4ecosh(4x)sinh(4x).

We can use the Chain Rule to solve this problem. The Chain Rule states that if f(g(x)) is the composite of two functions, f(x) and g(x), then the derivative of the composite is f'(g(x))g'(x). Here, f(x) = ex and g(x) = cosh(4x).

First, we will take the derivative of f(x). Using the Power Rule, we can take the derivative of f(x) = ex and get f'(x) = ex.

Next, we will take the derivative of g(x) = cosh(4x). The derivative of cosh(x) is sinh(x). Here, g'(x) = 4sinh(4x).

Finally, using the Chain Rule, we can take the derivative of y = ecosh(4x) and get y' = 4ecosh(4x)sinh(4x).

Step-by-step explanation:

The probability of a student doing well on an exam given that they spend time reading is approximately 0.983 or 98.3%.

To calculate the probability of a student doing well on an exam given that the student spends time reading, we need to use conditional probability.

Let's denote:

P(R) as the probability of a student spending time reading (P(R) = 0.59),

P(E) as the probability of a student doing well on an exam (P(E)),

P(E|R) as the probability of a student doing well on an exam given that they spend time reading (P(E|R) = 0.58).

The formula for conditional probability is:

P(E|R) = P(E and R) / P(R).

Given that P(E and R) = 0.58 (the probability of a student doing well on an exam and spending time reading) and P(R) = 0.59 (the probability of a student spending time reading), we can substitute these values into the formula:

P(E|R) = 0.58 / 0.59 = 0.983.

Therefore, the probability of a student doing well on an exam given that the student spends time reading is approximately 0.983 or 98.3%.

First right out all the data in numerical order from left to right.

2, 2, 2, 3, 4, 5, 7

The median is the middle number in the set.  If there is an even amount of data points, find the average of the two middle numbers.  If there is an odd number of data points, like in this data set, just take the middle number as you median.

There are 7 data points in this set so the fourth number in the set written in numerical order would be your median.

When writing this set out in numerical order, repeated numbers must be repeated, we find that the fourth, or middle, number is 3.  Therefore, 3 is the median of this data set.
