The number of trucks needed to deliver the rock in one trip will be 6.

Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:

V =  a x b x c

A transport company needs to deliver 500,000 pounds of rocks to a construction site.

The company owns a set of dump trucks- each with a container in the shape of a rectangular prism (figure A).

If each pound of rock has a volume of 0.01 cubic feet.

Then the total volume of rock that the transport company is responsible for.

Volume of rocks = 0.01 x 500,000

Volume of rocks = 5,000 ft³

Then the maximum volume of each dump truck will be

Volume of truck = 12 x 9 x 8

Volume of truck = 864 ft³

Then the number of the trucks are needed to deliver the rock in one trip will be

Number of trucks = 5000 / 864

Number of trucks = 5.787

Number of trucks ≅ 6

The arc length of the circle will be equal to 5.89 units.

The length of the curve on the circumference of the circle making an angle with the centre is called the length of the arc of the circle.

Given that:-

The length of the arc will be calculated as:-

Arc  =  Angle  x  radius

Arc  =  ( 3π / 4  )  x  2.5

Arc  =   5.89 units.

Choice B and Choice C

Step-by-step explanation:

Hello! This is how I solved this question:

(10 x 8 x 2) + (3 x 3 x 4) = 160 + 36 = 196ft^3

(10 x 3 x 2) + (5 x 4 x 2) = 60 + 40 = 100ft^3

(8 x 4 x 2) + (3 x 6 x 2) = 64 + 36 = 100ft^3

(8 x 10 x 3) + (4 x 5 x 2) = 240 + 40 = 280ft^3

Choice B and Choice C are the same values, and knowing that you need two of the same values for the volume of the figure must be the same. Giving you your two answers from simply multiplying and adding the answers.

Part A

The group of points labeled "T" can be thought of as the main cluster of points. Your teacher might have given another name for it, but this is how I think about it. All of these points are very close to a straight line.

The point R is known as an outlier. It is fairly far from the main cluster, in that it's not near the regression line. You can think of the points in the main cluster as houses along/near a straight road. The outlier house is unfortunately far from that road.

One possible reason for point R is that the student is very talented and can pick up music really easy, thereby not needing that much practice. Another reason is that the student already had tons of prior practice and experience, so they don't need as much practice currently.

============================================================

Part B

We have a strong positive linear association with the main cluster of data points. As mentioned earlier, a straight line is very close to these points. The closer they are to the same straight line, the stronger the correlation.

We have positive correlation because as x goes up, so does y. The variables increase together. Negative correlation happens when x and y go in opposite directions (one goes up, the other goes down).

The outlier point R pulls on the regression line to make it slightly not near the main cluster. The line tries its best to be near all of the points, and that includes the outlier. In some situations, the outlier is ignored and regression is done on the other set of points.

As you can probably guess, the outlier dilutes the strength of the correlation. The further the outlier, the weaker the correlation gets.

Answer:

The mean of the age data of the players is 20 and on average the age of each player is 1 far from mean.

The dot plot is the way of representation of the data. This data is plotted in the form of points or dots over an x-y axis. The dot plot is also known as the strip plot.

The data of the age of the player is,

18,19,20,21,21,21

The number of player are 6. Thus, the mean of the data is,

Mean=(18+19+20+21+21+21)/6

Mean=20

The distance form mean 20 of each player age is, 2,1,0,1,1,1. The mean deviation is,

Mean Deviation= (2+1+0+1+1+1)/6

Mean Deviation=1

Thus, the mean of the age data of the players is 20 and on average the age of each player is 1 far from mean.

The expected value of the net gain from selling the stock in 2 years is $-3.

The net gain is the total profit from selling the stock less the total cost of buying the stock

Total cost of buying the stock = 10 x $10 = $-100

The solution to the given quadratic expression using the completing the square is  x = ±√10 +8

This is a method of factoring quadratic expression. Given the quadratic function.

x^2 − 16x + 54 = 0

Subtract 54 from both sides

x^2 − 16x = -54

Complete the square

x^2 -16x +8^2 = -54 + 64

(x-8)² = 10
x - 8 = ±√10
x = ±√10 +8

The Probability of that more than 7 of them germinate is 0.2948.

We are to determine the probability that more than 7 of 10 seeds (i.e. 8, 0r 9 0r 10) germinate.

The probability that all 10 seeds germinate is equal 0.80¹⁰= 0.1073 = 10.73%.

The probability that only the first (only the second, etc ) seed does not germinate is equal 0.20 X 0.80⁹= 0.0268 = 2.68%.

The probability that 6 seeds germinate is the sum of the probabilities that only the first seed does not germinate, only the second one does not germinate, etc, and equals to 10 X 0.0268  = 0.268 = 26.8%.

The total probability that more than 7 of 10 seeds germinate is the sum of the probabilities that 10 seeds germinate and that 7 seeds germinate, i.e. 2.68 % + 26.8 % = 29.48 %.

Thus, The Probability of that more than 7 of them germinate is 0.2948.

Answer:

n = 7.

Step-by-step explanation:

Sum S of an AP = (n/2)[2a + d(n - 1)]

112 = (n/2)[2*25 - 3(n -1)]

n/2 (53 - 3n) = 112

n(53 - 3n) = 224

-3n^2 + 53n - 224 = 0

3n^2 - 53n + 224 = 0

(3n - 32 )(n  - 7 ) = 0

n = 7, 32/3

So n must be 7 as its a whole number.

Answer:

P(A) = 5/12

P(B) = 1/2

Step-by-step explanation:

A) Sum greater than 7

If the sum needs to be >7, then it can be 8, 9, 10, 11, and 12.

There are 26 out of 36 events where the sum is >7, thus P(A) = 15/36 = 5/12.

B) Sum is even

If we see in an overview of the sum distribution, there is a balanced division between odd and even numbers, thus the probability is very likely to be 1/2. Now let's make sure of it:

If the sum needs to be even, which means divisible by 2, then it can be 2, 4, 6, 8, 10, and 12.

There are 18 out of 36 events where the sum is even, thus P(B) = 18/36 = 1/2.
