Given equation:

Add - 6|x - 14| to both sides:

Add - 5 to both sides

No solution since the left side can't be negative as an absolute value.

The missing factor in the second equation is 1, and the completed equation is: -24y + (-5) = -4(6y + 5/4)

We know that the GCF of -24y and -20 is 4. To find the missing factor in each equation, we can divide both terms by the GCF of 4.

For the first equation, we have:

-24y = 4 * (-6y)

Dividing both sides by 4, we get:

-6y = -24/4

Simplifying, we get:

-6y = -6

Therefore, the missing factor in the first equation is -1, and the completed equation is:

-24y + 20 = -4(6y - 5)

For the second equation, we have:

-20 = 4 * (-5)

Dividing both sides by 4, we get:

-5 = -20/4

Simplifying, we get:

-5 = -5/1

Therefore, the missing factor in the second equation is 1, and the completed equation is:

-24y + (-5) = -4(6y + 5/4)

The probability that at least one of the two students will fail the examination is 0.7.

To find the probability that at least one of the two students will fail the examination, we can use the principle of complementary probability.

Let's denote the event of student A failing the examination as A and the event of student B failing as B.

We are given that P(A) = 0.5, P(B) = 0.2, and the probability that both student A and student B will fail the examination is denoted as P(A ∩ B).

The complementary probability of at least one student failing is equal to 1 minus the probability that both students pass the examination.

In other words:

P(at least one student fails) = 1 - P(both students pass)

To find P(both students pass), we can use the concept of independent events.

If the events A and B are independent, then:

P(A ∩ B) = P(A) \(\times\) P(B)

However, since we are not given information about the independence of A and B, we cannot assume they are independent.

Therefore, we cannot directly calculate P(both students pass) using the given information.

However, we can make use of the principle of inclusion-exclusion to calculate the probability that at least one student fails.

The principle states that:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Using this principle, we can calculate P(at least one student fails) as:

P(at least one student fails) = P(A) + P(B) - P(A ∩ B)

Substituting the given values, we have:

P(at least one student fails) = 0.5 + 0.2 - P(A ∩ B)

Unfortunately, without knowing the value of P(A ∩ B), we cannot provide a specific numerical answer.

However, we can conclude that the probability of at least one of the two students failing the examination is equal to 0.7 minus the unknown value of P(A ∩ B).

Answer:

a) f(x-1) = 2x^2-11x-1

b) x = -1.5 or 5

Step-by-step explanation:

a) To get f(x-1)

We proceed to substitute x-1 for x as follows

f(x-1) = 2(x-1)^2 -7(x-1) -10

f(x-1) = 2(x^2 - 2x + 1) -7(x-1)-10

f(x-1) = 2x^2 -4x + 2 -7x + 7-10

f(x-1) = 2x^2-11x-1

b) What we have to do here is substitute 5 for f(x) and solve for x

5 = 2x^2 -7x-10

2x^2 -7x -10-5 = 0

2x^2 - 7x - 15 = 0

2x^2 -10x + 3x -15 = 0

2x(x-5) + 3(x-5) = 0

(2x + 3)(x-5) = 0

2x + 3 = 0 or x -5 = 0

2x = -3 or x = 5

x = -3/2 or x = 5

x = -1.5 or 5

Step-by-step explanation:

Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.

To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.

Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.

Both Billy and Sam have the same proportion of cement in their mortar, which is 80% of the total mass. Billy's mixture has more cement than Sam's.

Billy and Sam make mortar by mixing cement and sand. Billy uses 360 kg of cement and 90 kg of sand, while Sam uses 340 kg of cement and 85 kg of sand. We need to determine which of them has a higher proportion of cement.

Let's calculate the proportion of cement in Billy's mortar:

Proportion of cement in Billy's mortar = (mass of cement / total mass of mixture) x 100%

Proportion of cement in Billy's mortar = (360 / (360+90)) x 100%

Proportion of cement in Billy's mortar = 80%

Now let's calculate the proportion of cement in Sam's mortar:

Proportion of cement in Sam's mortar = (mass of cement / total mass of mixture) x 100%

Proportion of cement in Sam's mortar = (340 / (340+85)) x 100%

Proportion of cement in Sam's mortar = 80%

Therefore, both Billy and Sam have the same proportion of cement in their mortar.

In other words, the amount of cement in their mixture is 80% of the total mass of the mixture. Billy's mixture has more cement than Sam's mixture.

The sampling method that is most likely to be appropriate for calculating confidence intervals is simple random sampling.

This method ensures that every member of the population has an equal chance of being selected for the sample. This reduces the risk of bias and ensures that the sample is representative of the population. Stratified sampling is also a useful method for calculating confidence intervals, especially when the population has subgroups that need to be represented in the sample. However, other sampling methods like convenience sampling or quota sampling are not appropriate for calculating confidence intervals as they can introduce bias into the sample and do not guarantee a representative sample. Therefore, it is important to use an appropriate sampling method when calculating confidence intervals to ensure that the results accurately reflect the population.

The probability that both Rachel and Robert are in the picture is 3/16.

The terms probability and possibility are interchangeable. It is a mathematical branch concerned with the occurrence of a random event. The value is between 0 and 1. In mathematics, the probability was introduced to predict the likelihood of events occurring.

Given that

Rachel and Robert both begin at the same point

Rachel completes a lap every 90 seconds.

Robert completes a lap every 80 seconds.

The photographer captures 1/4th of the track, centered on the starting line.

As a result, the photo captures 1/8th of the track on either side of the starting line.

The photographer captures it between 10 and 11 minutes, or 600 and 660 seconds.

Let us calculate the time interval between 600 and 660 seconds during which Rachel and Robert will be running in the quarter-length region of the track centered on the starting line. Specifically, 1/8th of the track length on each side of the starting line.

Robert will complete 1/8th of a lap in 10 seconds. So, between 630 and 650 seconds, Robert will be in the area of the ground captured by the photographer.

Rachel finishes one lap in 90 seconds. As a result, Rachel will take the starting line at the 630th second (after 7 laps).

Rachel will complete 1/8th of a lap in 90/8 seconds. So, Rachel will be in the area of the ground captured by the photographer from (630 - 90/80) seconds to (630 + 90/80) seconds.

i.e., for a duration of 90/80 seconds out of the 60 seconds both of them are in the frame captured by the photographer.

Required probability = {time window in which both Rachel and Robert are in the favorable zone}/{time window in which the photographer captures the picture}

= {90/8}/60

= 3/16

Therefore the probability that both Rachel and Robert are in the picture is 3/16

The interest rate required to get a total amount of $38,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 9 years is 9.0909 % per year.

The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR .

r = n[(A/P)1/nt - 1]

r = 1 × [(38,000.00/22,000.00)1/(1)(9) - 1]

r = 0.0909090

Then convert r to R as a percentage

R = r × 100

R = 0.0909090 × 100

R = 9.0909 %/year
