D. 2000 gallons per hour

Answers

Answer 1

Answer: 4,000

Step-by-step explanation:

Answer 2

The solution is Option A.

The rate at which the swimming pool is being filled is 66.6 gallons per hour

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of gallons be = y

Let the time taken be = x

The total volume of the pool = 15000 gallons

The pool is filled at constant rate

Now ,

The coordinate data is given as

The value of A = A ( 15 , 1000 )

The value of B = B ( 30 , 2000 )

The value of C = C ( 45 , 3000 )

Now , the rate at which the swimming pool is filled is given by the slope of the points in the line

So , the slope of the 2 points is given by the formula

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 2000 - 1000 ) / ( 30 - 15 )

On simplifying the equation , we get

Slope m = 1000 / 15

Slope m = 66.66 gallons per hour

Therefore , the value of A is 66.6 gallons per hour

Hence ,

The rate at which the swimming pool is being filled is given by the slope of the line where slope m = 66.6 gallons per hour

juan rolls a fair regular octahedral die marked with the numbers $1$ through $8$. then amal rolls a fair six-sided die. what is the probability that the product of the two rolls is a multiple of $3$?

Answers

The probability that the product of the two rolls is a multiple of 3 is 1/2.

Probability:

Probability mean the fraction of the possibility of the required event.

The formula for the probability is

P(E) = n(E)/n(S)

Where

P(E) = Probability of the event

n(E) = number of required event

n(S) = Total number of event

Given,

Juan rolls a fair regular octahedral die marked with the numbers 1 through 8.

Then Amal rolls a fair six-sided die.

Here we need to find the  probability that the product of the two rolls is a multiple of 3.

We know that,

On both dice, only the faces with the numbers 3,6 are divisible by 3.

Let

P(a) = 2/8

P(a) = 1/4

it is  the probability that Juan rolls a 3 or a 6,

and Similarly,

P(b) = 2/6

P(b) = 1/3

Is the probability of Amal does.

By the Principle of Inclusion-Exclusion,

[tex]\[P(a \cup b) = P(a) + P(b) - P(a \cap b) = \frac{1}{4} + \frac{1}{3} - \frac{1}{4} \cdot \frac{1}{3} = \frac{1}{2} \Rightarrow \mathrm{(C)}\][/tex]

Thus the total probability is 1/2.

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.

What are the numerical values of x, segment PQ, QR and PR?

Given the data in the question;

Q is a point between P and RSegment PR = 5x - 3Segment PQ = 2x + 8Segment QR = x + 11Numerical value of x, segment PQ, QR and PR = ?

Since Q is a point between P and R.

PR = PQ + QR

Plug in the given values and solve for x.

5x - 3 = ( 2x + 8 ) + ( x + 11 )

5x - 3 = 2x + 8 + x + 11

5x - 3 = 3x + 19

5x - 3x = 19 + 3

2x = 22

x = 22/2

x = 11

Numerical value of segment PQ when x = 11 will be;

PQ = 2x + 8 = 2(11) + 8 = 30

Numerical value of segment QR when x = 11 will be;

QR = x + 11 = (11) + 11 = 22

Numerical value of segment PR when x = 11 will be;

PR = 5x - 3 = 5(11) - 3 = 52

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.

Answers

The location of point D on the number line is -5.15625

How to determine the location of point D?

The given parameters are:

A = 5

B = -10

AC : CB = 1 : 3

This means that

C = AC/(AC + AB) * (A - B)

This gives

C = 1/4 * (5 + 10)

Evaluate

C = 3.75

Also, we have:

BD : DC = 3 : 5

what are the two major advantages of experimental research over correlational studies? multiple select question. experiments are more efficient. causal relationships can be inferred. random assignment is possible. sample size is always greater in experiments.

Answers

The experimental research has two key advantages over correlational studies.

1. The possibility of random assignment

2. Causal connections can be assumed.

What benefit does experimental research have over correlational research?

Correlational studies merely examine the data that already exists, whereas experimental studies give the researcher the opportunity to influence the study's factors. Researchers can make inferences about how changes in one variable affect changes in another through the use of experimental investigations.

The factors in a correlation study are out of the control of the researcher or research team. The researcher merely measures the information she discovers in the outside world. She can then determine whether changes in one are related to changes in the other, or if the two variables are correlated. In such a study, experimenters gather existing data and use statistical methods to examine it, such as economic statistics from governments. The findings of correlation studies can lead to hypotheses that can be verified through a more focused experimental one.

A. What is the size of the game in standard

B. how many times larger was the game than the patch file

Answers

Part a: The size of the game in standard form is 240000 kilobytes

Part b: The game was 5 times larger than the patch file

Part A:

Size of the game downloaded by Ryan on his computer = 2.4 * 10^5

Size of the patch file for the game = 48000 kilobytes

Therefore, converting the size of the game into the standard form:

Size of the game = 2.4 * 10^5

= 2.4 * 100000

= 240000 kilobytes

Therefore, the size of the game is 240000 kilobytes in standard form

Part B:

Size of the game = 240000 kilobytes

Size of the patch file = 48000 kilobytes

Computing the size of the game with respect to the patch file we get:

=240000/48000

= 5

Hence, the game was 5 times larger than the patch file

Answers

By using the given pair of values we can see that the constant of proportionality is 8, and the proportional relation is:

y = 8*x

How to determine the proportional relation?

A proportional relation is a linear relation with an y-intercept of 0, so these are written as:

y = a*x

Where a is the constant of proportionality.

By knowing a pair of values x and y, we can find the value of a. In this case we can see that when x = 3, y = 24, replacing that in the general equation we get:

To the closest hundred, 341 is equivalent to 300. This is due to the fact that 341 is more similar in value to 300 than to 400. Because $1.89 is closer to $2.00 than to $1.00, when rounded off to the nearest dollar, it becomes $2.00.

The given statement is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.

A vector is defined by its length and direction. If two vectors have the same direction, they are parallel. The length is irrelevant.If the length of a vector is one, it is a unit vector. The direction is irrelevant.So, in order to locate a unit vector parallel to another vector, it must point in the same direction and be of length 1.For a given non-zero vector, there are an infinite number of parallel vectors to it but with different magnitudes. There is only one vector which is not only parallel to the given non-zero vector but also has a magnitude of 1, i.e., the unit vector parallel to it.Thus, it is true that for a given non-zero vector v in r³ there is a unique unit vector parallel to it.

Answers

The height of the building = 1026.328ft

Given the angle of elevation = 11°

The angle of elevation is the angle formed between the horizontal distance to the base of the building and the line of sight to the top of the building.

We know that tan x = opposite side/adjacent side.

Here the opposite side gives the height of the building and the adjacent side is the distance to the base of the building on the ground.

Distance to the base of the building on the ground = 1 mile = 5280 ft.

So tan 11° = h/5280

⇒ h= tan 11° x 5280 = 0.194 x 5280 = 1026.328 ft
