Answer: 3/4

Step-by-step explanation:

First we need to get the formula into slop form (Y = Mx + B) by moving Y to the other side. This can be done by adding 3y to both sides.

4x - 42 = 3y

or

3y = 4x - 42

Now that we have the formula, we need to divide everything by 3 in order to get 1y.

y = 3/4x - 14

In this formula, M is the slope, meaning your final answer is

3/4

a) The evaporation rate per square foot of surface area (in gal/A) is equals to the 1/12 gal/A.

b) The thirty-three gallons of water will evaporate from a pool of 200 square feet.

We have, Area of a pool = 200 square feet

and we have to determine quantity of water evaporate from a pool in gallons. For this, first we have to calculate the evaporation rate. Let's assume y = gallons of water and

x = surface area in square foot

From the data, dy/dx = (50-25) / (400-100)

=> dy/dx = 1/12

The above equation means that for every 12 square feet surface there is 1 gallons water of evaporation will happen. So, similarly for 100 square feet = 100/12 gallons water

=> 8.33 gallons

But for 100 square feet 25 gallons of evaporation will happen.

=> 25 - 8.33 = 16.67

b) Now we will calculate quantity of water will evaporate from a pool of 200 square feet. As we know, 1 gallon for 12 square feet, so number of gallons for 200 square foot = 200/12

= 16.66

Now we add 16.67 for answer that is 16.66+ 16.67 = 33.33 ~ 33 gallons of water. Hence, required value is 33 gallons.

Answer:

149

Step-by-step explanation:

12× 24 = 288

228 - 139 = 149

Answer:

B. 149

Step-by-step explanation:

If the students have already filled 139 balloons with air and are going to use all the bags. They would need to fill 149 more balloons.

The first step would be to find the total number of ballons by calculating 12x24 which will give you 288.

From here you would need to subtract the number of ballons that are already filled with air from the balloons that remain which would be 288-139. This would give you a total of 149 balloons that still need to be inflated.

The sequence in which the three classes might be served in order to achieve the WFQ weights is: Class 1: 25%, Class 2: 50%, Class 3: 75%

WFQ scheduling policy stands for the Weighted Fair Queuing scheduling policy. It is a packet scheduling technique that is utilized in Quality of Service (QoS) for network resources that are shared among different applications and users. The WFQ technique aims at equalizing the traffic and providing fair access to network resources. WFQ is an improvement over traditional Round Robin scheduling.

WFQ assigns the weights to different classes and sorts the packets in the buffer based on priority. It then serves the packets by assigning transmission time slots to them. The packets with the highest priority are served first and so on until all the packets have been served.

The WFQ scheduling policy is applied to a buffer that supports three classes of priority packets, and the weights are 0.25, 0.5, and 0.75 for the three classes. To achieve the WFQ weights, the three classes might be served in the following sequence: Class 1: 25%, Class 2: 50%, Class 3: 75%

Answer: \(25\ mph\)

Step-by-step explanation:

Given

Jane took 3 hours

First she rode 48 miles with let say with \(x\) mph

then she rode 15 miles with speed \((x+5)\) mph

Equate the time in each ride and equate it to total time

The forecast for May using a five-month moving average is 39 (Option E).

Moving average is used for smoothing out time series data to find any trends or cycles within the data. A five-month moving average is the average of the past five months. To calculate the moving average, add up the sales for the previous five months and divide it by five.

According to the question, the sales for the previous five months are: Nov. 39 Dec. 27 Jan. 40 Feb. 42 Mar. 41 April 47

We have to add the sales of these five months, which gives:

27 + 40 + 42 + 41 + 47 = 197

To find the moving average for May, we divide this sum by 5:

197 / 5 = 39.4

Since we have to round the answer to the nearest whole number, we round 39.4 to 39, which is option E.

x = {x | x ≠ 0, x ≠ ±7} is the domain of the given function h(x)  = 9x/x(x²-49). So, Option B is the correct option.

Functions are used to assign outputs to inputs. A function's domain is the collection of all potential inputs to the function. The domain of f(x)=x2 is all real numbers, for example, whereas the domain of g(x)=1/x is all real numbers except x=0.

Consider the function y = f(x) to have an independent variable x and a dependent variable y. If a function f provides a technique to successfully create a single value y using a value for x, that chosen x-value is said to belong to f's domain.

The given function is  h(x)  = 9x/x(x²-49)

We need to determine the domain of this function.

Let us equate the denominator of the function to zero to find x value.

x(x²-49) = 0

x = 0

x²-49 = 0

x = ± 7

Thus, x = 0,-7,+7

So, domain can be intervals between the x values obtained but cannot be equal to the x values.

Therefore, x = {x | x ≠ 0, x ≠ ±7} is the domain of the given function h(x)  = 9x/x(x²-49). So, Option B is the correct option.

In a binomial experiment with n=20 and p=0.70, we are asked to calculate the probabilities P(x=8), P(x=10), P(x=12), and P(x=17). We will use Excel to compute these probabilities and then match them to the correct values.

To calculate the probabilities in a binomial experiment, we can use the binomial probability formula:

P(x) = (nCx) * p^x * (1-p)^(n-x)

where n is the number of trials, p is the probability of success, x is the number of successful outcomes, and nCx represents the number of combinations of n items taken x at a time.

Using Excel, we can use the BINOM.DIST function to calculate these probabilities. We will specify the value of x, the number of trials (n), the probability of success (p), and set the cumulative parameter to FALSE to get the probability of a specific value.

For P(x=8), we will use the formula: "=BINOM.DIST(8,20,0.70,FALSE)".

For P(x=10), we will use the formula: "=BINOM.DIST(10,20,0.70,FALSE)".

For P(x=12), we will use the formula: "=BINOM.DIST(12,20,0.70,FALSE)".

For P(x=17), we will use the formula: "=BINOM.DIST(17,20,0.70,FALSE)".

After calculating these probabilities using Excel, we can match the results with the provided options to determine the correct values for each probability.

Use the percent proportion to solve:

Percent/100 = Part/Whole

In this case:

62/100 = 190.5/W    (W for whole, we are trying to find the whole)

Cross multiply:

62w = 100(190.5)

Multiply 100 by 190.5:

62w = 19,050

Answer:

Y= -3/4 x -3

Step-by-step explanation:

The probability of getting a score of 80% or higher is 0.18750.

We are given that;

The probability of getting a score = 80%

Now,

We can use the binomial probability formula:

\($$P(X) = {n \choose x} p^x (1-p)^{n-x}$$\)

where P(X) is the probability of getting x successes out of n trials, p is the probability of success on each trial and (1-p) is the probability of failure on each trial.

In this case, we have:

n = 5 the number of questions on the quiz

x = 4 or x = 5, the number of correct answers needed to get 80% or higher

p = 0.5, the probability of guessing correctly on each question

(1-p) = 0.5, the probability of guessing incorrectly on each question

So, we can plug these values into the formula and calculate the probabilities for x = 4 and x = 5:

\($$P(X=4) = {5 \choose 4} (0.5)^4 (0.5)^{5-4} = \frac{5!}{4!(5-4)!} (0.5)^4 (0.5)^1 = \frac{5}{1} (0.0625) (0.5) = 0.15625$$$$P(X=5) = {5 \choose 5} (0.5)^5 (0.5)^{5-5} = \frac{5!}{5!(5-5)!} (0.5)^5 (0.5)^0 = \frac{1}{1} (0.03125) (1) = 0.03125$$\)

To find the probability of getting 80% or higher, we need to add these two probabilities:

\($$P(X \geq 4) = P(X=4) + P(X=5)\)

= 0.15625 + 0.03125 = 0.18750$$

Therefore, by probability the answer will be 0.18750.
