Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 2 )

This means subtract 4 from the original x- coordinate and add 2 to the original y- coordinate, that is

a point (4 , - 4 ) → (4 - 4, - 4 + 2 ) → (0, - 2 )

The resulting graph would result in moving input x by --4  horizontally and Output y by +2 vertically.

Translations are defined by saying how much a point is moved to the left/right and up/down. Vertically translating a graph is equivalent to shifting the base graph up or down in the direction of the y-axis. A graph is translated k units vertically by moving each point on the graph k units vertically.

Given the point  (x - 4, y + 2), we can clearly observe that the graph would move vertically by +2 units while the input will be in the -ve x-axis direction from right to left and thus will move negatively by -4.

Hence, The resulting graph would result in moving input x by --4  horizontally and Output y by +2 vertically.

The reference angle for the angle with the measure 2x/3 is 54⁰

You should understand that a reference angle is the acute angle to a given angle.

The given angle is 2x/3

We should understand that since the angle has the variable x

= x + 2x/3 = 90⁰

Simplifying the fraction to have

(3x+2x)/3 = 90

Cross and multiply we have 5x=270⁰

Making x the subject

x= 270/5

x=54⁰

The solutions to the quadratic equation 6x² = -3x + 1 to the nearest hundredth are -0.73 and 0.23.

Given the quadratic equation in the question:

6x² = -3x + 1

To solve the quadratic equation 6x² = -3x + 1, we can rearrange it into standard form, where one side is set to zero:

6x² + 3x - 1 = 0

Now we can solve the equation using the quadratic formula, which states that for an equation in the form ax² + bx + c = 0, the solutions for x are given by:

\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\)

Here; a = 6, b = 3, and c = -1.

Let's substitute these values into the quadratic formula:

\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\\\\ x= \frac{-3 \±\sqrt{3^2-4\ *\ 6\ *\ -1} }{2*6}\\\\x = \frac{-3 \±\sqrt{9+24} }{12}\\\\x = \frac{-3 \±\sqrt{33} }{12}\\\\x = -0.73, \ x=0.23\)

Therefore, the values of x are -0.73 and 0.23.

The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.

The Mean is defined as the ratio of sum of numbers present in the data to the total numbers present in the data. Median is defined as the ratio of sum of middle numbers present in the data. Mode is defined as the most recurring number present in the data. Midrange is the ratio of the largest and smallest number in the data to 2.

Let's see how to calculate Mean, Median, Mode and Midrange.

Mean = 13 + 15 + 18 + 18 + 21 / 5

Mean = 85 / 5

Mean = 17

Median = 18 (as it is the middle term of the data)

Mode = 18 (as it is most recurring number)

Midrange = 21 + 13 / 2

Midrange = 34 / 2

Midrange = 17

Therefore, The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.

After making payments for 15 years, the amount still owed on the mortgage would be approximately $145052.36.

To determine how much will still be owed after making payments for 15 years, we can use the formula for the remaining balance on a mortgage:

Remaining balance = P ((1 + r)ⁿ - (1 + r)ᵇ) / ((1 + r)ⁿ - 1)

where:

P = the initial loan amount (in this case, $219,000)

r = the monthly interest rate (which is the annual interest rate divided by 12)

n = the total number of monthly payments (which is 30 years times 12 months per year, or 360 months)

b = the number of monthly payments made so far (which is 15 years times 12 months per year, or 180 months)

First, we need to calculate the monthly interest rate:

r = 4.5% / 12 = 0.00375 = 0.375%

Next, we can plug in the values to get:

Remaining balance = $219,000 ((1 + 0.00375)³⁶⁰- (1 + 0.00375)¹⁸⁰) / ((1 + 0.00375)³⁶⁰ - 1)

Carter is a salesperson who sells computers at an electronics store.

He gets paid a base pay amount each day and a commission for every computer sale he makes.

Carter's total pay on a day depends on the number of computers he sells, represented by x.

The relationship between x and Carter's total pay, represented by P, is linear.

linear means the graph is a straight line, not a curve

A table with select values of x and P is given.

The task is to determine Carter's base pay regardless of computer sales.

Table of select values of x and P:

x P

0 30

1 40

2 50

3 60

4 70

5 80

To determine Carter's base pay, we need to identify the amount he earns when he doesn't sell any computers, represented by x = 0. Looking at the table, we see that when x = 0, Carter's total pay is $30. Therefore, his base pay is $30.

The area as just a function of width is given by the function.

(2w - 7) inches.

The width of such a rectangle if its size is 60 square inches.= 7.5 inches

A quadratic problem is a sort of problem in mathematics that deals with the a variable multiplied on it's own – a process known as squares. The area of a square is defined as its side length multiplied twice itself in this language. The term "quadratic" is derived from the Latin word quadratum, which means "square."

For the part A.

Let w indicate the rectangle's width.

A rectangle's length is 7 inches just under twice its width, w. That is, the length is (2w - 7) inches.

For the part B.

If the rectangle has a surface size of 60 square inches, it signifies that

w(2w - 7) = 60

2w² - 7w = 60

2w² - 7w - 60 = 0

(2w² + 8w - 15w - 60) = 0

2w(w + 4) - 15(w + 4) = 0

2w - 15 = 0 or w + 4 = 0

w = 15/2

w = - 4

Because w cannot be negative,

w = 15/2

= 7.5 inches

Answer: Yes

Step-by-step explanation:

1 ton = 2000 pounds and 500 is 1/4 of 2000

Answer: Yes

Step-by-step explanation:

We know that 1 ton is 2000 pounds. We can use this fact to figure out if 500 pounds is equivalent to 1/4 tons. To do so, we can use a proportion.

\(\frac{2000 pounds}{1 ton} =\frac{500pounds}{x}\)

\(2000x=500\)

\(x=\frac{500}{2000} =\frac{5}{20} =\frac{1}{4}\)

Now, we know that 500 pounds is equivalent to 1/4 tons. Therefore, 2 tons and 500 pounds is equivalent to \(2\frac{1}{4}\) tons.

Answer:

1. 69.15% probability that the project will be completed on day 32 or earlier

2. 15.87% probability that the project will be delayed

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation(which is the square root of the variance) \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\(\mu = 30, \sigma = \sqrt{16} = 4\)

1. What is the probability that the project will be completed on day 32 or earlier?

This is the pvalue of Z when X = 32. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{32 - 30}{4}\)

\(Z = 0.5\)

\(Z = 0.5\) has a pvalue of 0.6915

69.15% probability that the project will be completed on day 32 or earlier

2. Suppose the official deadline for the project is 34 days. What is the probability that the project will be delayed?

This is 1 subtracted by the pvalue of Z when X = 34. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{34 - 30}{4}\)

\(Z = 1\)

\(Z = 1\) has a pvalue of 0.8413

1 - 0.8413 = 0.1587

15.87% probability that the project will be delayed
