Answer:

Yes, the length of the intercepted arc will have the same measurement. When a central angle intercepts an arc of a circle, the measure of the angle is equal to the measure of the intercepted arc. In this case, both angles ABC and DEF are right angles, which means that they each intercept half of the circle. Therefore, the length of the intercepted arcs will be the same.

The points that are in the solution set are (-1, -1) and (2, -1).

Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.

To calculate the number of gallons of gas Simon needs for his trip, you can use the following formula:

Gallons = Miles / Miles per gallon

First, convert the distance of 2,804 miles to miles per gallon by dividing by the car's average mileage per 2

gallons:2,804 / 48.6 = 57.75 mpg

Then, use this value to calculate the number of gallons of gas Simon needs for his trip:

Gallons = Miles / Miles per gallon

Gallons = 2,804 / 57.75

Gallons ≈ 48.6 gallons

Therefore, Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.

The answer should be rounded to the nearest tenth, so the final answer is 48.6 gallons.

When skiing down a mountain with a vertical height of 1150 feet and a base-to-top distance of 2300 feet, the angle of elevation from the base to the top of the mountain is approximately 26.56 degrees.

When skiing down a mountain with a vertical height of 1150 feet and a base-to-top distance of 2300 feet, the angle of elevation from the base to the top of the mountain is given by tan⁻¹(1150/2300).

How to find the angle of elevation from the base to the top of the mountain?

The angle of elevation of an object from a point is the angle between the horizontal and the line of sight from the observer to the object above the horizontal. We can use the inverse tangent function to calculate this angle of elevation.

Step 1: Find the tangent of the angle of elevation: Let the height of the mountain be h and the distance from the base to the top of the mountain be d. Then tan(θ) = h/d.

Step 2: Inverse tangent of the height and distance of the mountain: Take the inverse tangent of the quotient to find the angle of elevation from the base to the top of the mountain. θ = tan⁻¹(h/d).Here, h = 1150 feet and d = 2300 feet. Substituting these values in the formula θ = tan⁻¹(1150/2300), we can find the angle of elevation from the base to the top of the mountain.θ = tan⁻¹(1150/2300) = 26.56 degrees.

So, the angle of elevation from the base to the top of the mountain is approximately 26.56 degrees.

The probability of the outcome being a red counter, or a blue counter is equal, therefore Trevor is wrong.

We know that Trevor has a bag of counters with 26 red counters and 26 blue counters and that he has already randomly picked one red counter 5 times but he places them back in the bag again and mixes them, but he thinks that the next counter he picks has a greater probability of being blue than red.

Trevor is wrong as we know that the likelihood of an occurrence is denoted by a numerical value known as probability. This value falls between 0 and 1 or can be represented as a percentage between 0% and 100%. The higher the probability of an event, the greater the chances of its occurrence. An impossible event has a probability of 0, while a certain event has a probability of 1.

To calculate probability, divide the number of ways the event can occur by the total number of outcomes.

Coach A can make 120 free throws in 3 minutes for number of free throws that Coach A can make varies directly with the amount of times she spends shooting the baskets.

A mathematical connection when two variables are involved in which the ratio of their values is constant is known as direct variation. Alternatively said, if one variable is multiplied by a specific amount, the second variable will also be multiplied by the same value. The two variables in this connection may be represented as a percentage, where the constant of proportionality is the ratio of their values, and the two variables are on opposite sides of an equal sign.

Given that, she can make 20 baskets in 30 seconds.

Thus, using proportion we have:

Free throws / Time = Free throws per unit time

20 baskets / 30 seconds = 2/3 baskets per second

Now, for 3 minutes or 3(60)n= 180 seconds we have:

Free throws = Time x Free throws per unit time

In order to determine the volume of a solid of revolution revolving around an axis that is alternatively the x or y-axis, the technique of cylindrical shells can be employed.

The general steps for doing this are as follows:

First, recognizing the area to revolve and the central axis must take place.

Second, an expression for the distance from the pivotal point to every single point within the region should be established; let us denote this distance as 'r'.

Then, discovering the measurement of each individual cylindrical shell can also be necessary by obtaining the distinction between two separate vertical points within the region; we shall refer to this tallest height identified as 'h.'

z = (sample mean - population mean) / (population standard deviation / sqrt(sample size))
z =[tex] (28 - 26.9) / (3.6 / sqrt(35))[/tex]
z = [tex] 1.1 / (3.6 / 5.916)[/tex]

When you put together 8 copies of the unit fraction 1/2, you are essentially adding 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2.

To add fractions, you need to make sure the denominators are the same. In this case, all the fractions already have the same denominator of 2.

So, we can add the numerators together:

1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 8/2

Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

The probability that Joe will be accepted at one, and only one, the university is E. 0.45.

The probability that Joe will be accepted at one, and only one, university can be calculated using the following approach. First, we need to find the probability of Joe being accepted at each university individually and the probability of him not being accepted at each university. The acceptance rate for applicants with similar qualifications is 25 percent for University A and 40 percent for University B.

Let's use the following notations:

P(A) - probability of being accepted at University A

P(B) - probability of being accepted at University B

P(A') - probability of not being accepted at University A

P(B') - probability of not being accepted at University B

We are given:

P(A) = 0.25

P(B) = 0.40

To find the probability of not being accepted, we subtract the probability of being accepted from 1:

P(A') = 1 - P(A) = 1 - 0.25 = 0.75

P(B') = 1 - P(B) = 1 - 0.40 = 0.60

Now, we want to find the probability of Joe being accepted at one university and not at the other. There are two possibilities:

(1) he gets accepted at University A and not at University B or

(2) he gets accepted at University B and not at University A.

We can use the multiplication rule for independent events and the addition rule for mutually exclusive events to calculate this probability:

P(A and B') + P(A' and B)=

P(A) * P(B') + P(A') * P(B) =

(0.25 * 0.60) + (0.75 * 0.40) =

0.15 + 0.30 = 0.45

So, the probability that Joe will be accepted at one, and only one, university is 0.45. Therefore, the correct option is E. 0.45.
