The rule for the reflection is that when reflecting over the x-axis, the x-coordinate remains the same but the y-coordinate changes to the opposite sign.

The x-coordinate must remain constant when reflecting across the x-axis, but the y-coordinate must change to the opposite sign. When reflecting over the y-axis, the y-coordinate remains the same but the x-coordinate changes to the opposite sign.

A figure is transformed into a reflection by a transformational process. In a point, a line, or a plane, figures can be reflected. The image and preimage coincide when reflecting a figure in a line or a point.

Every point of a figure is translated to an image across a fixed line via a reflection. The fixed line is referred to as the reflection line.

What is the rule for the reflection?

Answer:

4.3 hours

Step-by-step explanation:

Let the number of hours Sally does a job = x

Let the number did hours Joan does a job be equal to y

Sally and Joan were able to dust the house in 3 hours together.

1/x + 1/y = 1/3

It takes Joan 10 hours to finish the same job alone.

Hence,

1/x + 1/10 = 1/3

1/x = 1/3 - 1/10

Least common dey = 30

1/x = 10 - 3/30

1/x = 7/30

Cross Multiply

x × 7 = 30

7x = 30

x = 30/7

x = 4.2857142857 hours

Approximately = 4.3 hours

Without help, it would take Sally 4.3 hours to finish the same job.

The probability of a student having a quiz grade of 90 or greater is 7.4%.

The probability of a student having a quiz grade of 90 or greater can be calculated using the standard normal distribution. The formula used to calculate this probability is P(x ≥ 90) = 1 - P(x < 90).

The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. To convert our quiz grade to a z-score, we must subtract the mean (80) from our quiz grade (90) and divide by the standard deviation (7). This gives us a z-score of 1.43.

To calculate the probability of a quiz grade of 90 or greater, we subtract the cumulative probability of a z-score of 1.43 from 1. This can be done using a z-table or a calculator. The result of this calculation is 0.0740 or 7.4%.

In conclusion, the probability of a student having a quiz grade of 90 or greater is 7.4%.

Answer:

A

Step-by-step explanation:

\(\boxed{slope = \frac{y1 - y2}{x1 - x2} }\)

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Thus, using the above formula,

The probability that a randomly chosen labor force participant has a high school diploma or fewer years of education given that he or she is unemployed is approximately 0.999 or 99.9%.

To find the probability that a randomly chosen labor force participant has a high school diploma or fewer years of education given that he or she is unemployed, we can use Bayes' theorem.

Let's define the following events:

A: Labor force participant has a high school diploma or fewer years of education.

B: Labor force participant is unemployed.

We are looking for P(A|B), the probability that a labor force participant has a high school diploma or fewer years of education given that he or she is unemployed.

According to the information given:

P(A) = 0.381 (38.1% of the labor force has a high school diploma or fewer years of education)

P(B|A) = 0.051 (5.1% of those with a high school diploma or fewer years of education are unemployed)

P(B) = (P(A) * P(B|A)) + (P(A') * P(B|A')) [using the Law of Total Probability]

P(A') = 1 - P(A) = 1 - 0.381 = 0.619 (complement of having a high school diploma or fewer years of education)

P(B|A') = 0.035 (3.5% of those with some college or an associate's degree are unemployed)

P(B|A) = 0.028 (2.8% of those with a bachelor's degree or more education are unemployed)

Substituting these values into the equation for P(B):

P(B) = (0.381 * 0.051) + (0.619 * 0.035)

Now we can calculate P(A|B) using Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)

Substituting the values we have:

P(A|B) = (0.051 * 0.381) / P(B)

Calculating P(B):

P(B) = (0.381 * 0.051) + (0.619 * 0.035) = 0.019431

Substituting the calculated value of P(B) into the equation for P(A|B):

P(A|B) = (0.051 * 0.381) / 0.019431 ≈ 0.999

Therefore, the probability that a randomly chosen labor force participant has a high school diploma or fewer years of education given that he or she is unemployed is approximately 0.999 or 99.9%.

Compute the Gaussian density for the following cases. (a) x=0, m=0, s-1. Give the name of question5a (b) x-2, m=0, s-1. The value of the account on January 1, 2021, would be $2,331.57.

To calculate the value of the account on January 1, 2021, we need to consider the compounding interest for each year.

First, we calculate the value of the initial deposit after three years (12 quarters) using the formula for compound interest:

Principal = $1,000

Rate of interest per period = 8% / 4 = 2% per quarter

Number of periods = 12 quarters

Value after three years = Principal * (1 + Rate of interest per period)^(Number of periods)

                           = $1,000 * (1 + 0.02)^12

                           ≈ $1,166.41

Next, we calculate the value of the additional $1,000 deposit made on January 1, 2019, after two years (8 quarters):

Principal = $1,000

Rate of interest per period = 2% per quarter

Number of periods = 8 quarters

Value after two years = Principal * (1 + Rate of interest per period)^(Number of periods)

                         = $1,000 * (1 + 0.02)^8

                         ≈ $1,165.16

Finally, we add the two values to find the total value of the account on January 1, 2021:

Total value = Value after three years + Value after two years

                ≈ $1,166.41 + $1,165.16

                ≈ $2,331.57

Therefore, the value of the account on January 1, 2021, is approximately $2,331.57.

In order to have an equation with no solution, the variable x should not appear in the equation and the final sentence must be false.

So, using the variable 'y' to represent the missing number and simplifying the equation, we have:

Since we want the variable x to disappear (this way we will have 0 = 20, which is false), we need the coefficient (10 - y) to be zero:

So the missing number is 10.

The value of the missing sides are

x = -12

y = 109

z = -102

Consecutive Interior Angles: These are the angles that are on the same side of the transversal and inside the parallelogram. They are supplementary, which means their sum is 180 degrees.

-z + 1 + 77 = 180

-z = 180 - 1 - 77

-z = 102

z = -102

Alternate Interior Angles: These are the angles that are on opposite sides of the transversal and inside the parallelogram. They are also congruent, meaning they have the same measure.

y - 6 = -z + 1

y - 6 = 102 + 1

y = 103 + 6

y = 109

The total area of the colored rectangles is 62 square feet

Given that: the room is  12 x 16 with an 8 x 10 piece of linoleum centered in the room

The shape will be treated as a composite rectangle. Thus, the room can be divided into smaller rectangles as shown in the image attached.

For the Yellow part:

Length(L) = 8 + 2 = 10 feet

width(W) = 3 feet

Area(A) = L × W

A = 10 × 3 = 30 square feet

For the Blue part:

Length(L) = 2 feet

Width(W) = 3 + 10 = 13feet

Area(A) = L × W

A = 13 × 2 = 26 square feet

For the Green part:

Length(L) = 2 feet

width(W) = 3 feet

Area(A) = L × W

A =  2 × 3 = 6 square feet

Total colored area = Area of Yellow +  Area of Blue +  Area of Green

Total colored area = 30 + 26 + 6 = 62 square feet

Answer:

52 in^2

Step-by-step explanation:

If the diameter = 3 in, then the radius = 1.5 in.

To find the surface area, you need to find the area of the two circle areas (the base and the top of the cylinder) and the "sides" of the cylinder. If you look at the net shape of a cylinder, look at the picture below. That middle region aka the "side" of the cylinder is actually a rectangle. The length of the rectangle is also the circumference of the circle and the width is also the height of the can.

So:

2 * Area of the circle + rectangle = total surface area of the can

= 2(πr^2) + 2πrh

= 2π(1.5^2) + 2π(1.5)(4)

= 2π(2.25) + 12π

= 4.5π + 12π

= 16.5π
