This question is based on the equation of circle. Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

Given:

A circle with center (4, -7) and radius 9.

We need to determined the equation describes a circle with center (4, -7) and radius 9.

According to the question,

As we know that, the equation of a circle in standard form is

⇒ (x - h)² + (y - k)² = r²

Where (h, k) are the coordinates of the center and r is the radius.

Here, it is given that,  (h, k) = (4, - 7) and r = 9.

Therefore, by putting the given values.

We get,

⇒ (x - 4)² + (y - (- 7))² = 9², that is

⇒ (x - 4)² + (y + 7)² = 81 ← equation of circle

Therefore, the equation of circle is  (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

Answer:

the answer is A or F (both are the same answer which is 40)

Answer:

a. 0.8944 = 89.44% probability that the player functions for at least 8 hr

b. 0.9938 = 99.38% probability that the cassette player works for at most 11 hr

c. z* = 10.024 hr

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 p-value, we get the probability that the value of the measure is greater than X.

Mean value of 9 hr and a standard deviation of 0.8 hr

This means that [tex]\mu = 9, \sigma = 0.8[/tex]

a. What is the probability that the player functions for at least 8 hr?

This is 1 subtracted by the pvalue of Z when X = 8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{8 - 9}{0.8}[/tex]

[tex]Z = -1.25[/tex]

[tex]Z = -1.25[/tex] has a pvalue of 0.1056

1 - 0.1056 = 0.8944

0.8944 = 89.44% probability that the player functions for at least 8 hr.

b. What is the probability that the cassette player works for at most 11 hr?

This is the pvalue of Z when X = 11. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{11 - 9}{0.8}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a pvalue of 0.9938

0.9938 = 99.38% probability that the cassette player works for at most 11 hr.

c. Find a number z* such that only 10% of all cassette players will function without battery replacement for more than z* hr.

This is the 90th percentile, which is X when Z has a pvalue of 0.9, that is, X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 9}{0.8}[/tex]

[tex]X - 9 = 1.28*0.8[/tex]

[tex]X = 10.024[/tex]

So

z* = 10.024 hr

Answer:

12x-3y

Step-by-step explanation:

combine like terms: the 10x and the 2x can be combined making it 12x and then you keep the -3y making it 12x-3y

Answer:

12x - 3y

Step-by-step explanation:

All you have to do for this question is combine like terms. It isn't wanting you to solve for anything, so it's pretty fast to do. Since the 2 and 10 both have x values next to them, you can combine them. They are both positive, so you can simply add them together. This gives you 12x. Because the -3 and 12 have different values next to them, you cannot combine them. So you are left with 12x - 3y. This is your answer.

I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day and good luck!!

Answer and Step-by-step explanation:

1. Line - This figure is a line because it has two arrows, one at each end of the figure. Lines are continuous, meaning they go on forever.

2. Line Segment - This is a line segment because it has and end point at each side of the figure. Line segments are segments of a line, and are not continuous.

3. Ray - This is a ray because it has 1 endpoint and 1 arrow. It goes on forever in one direction, but stops at the other end.

Answer:$7,450

Step-by-step explanation:

Answer:

0.375 lb

Step-by-step explanation:

For this one all you need to do is convert 6 oz to pounds and to do this

For example to convert an ounce measurement to a pound measurement, use a simple formula. Since one ounce is equal to 1/16 of a pound, the formula for the conversion is:

pounds = ounces ÷ 16

1. Take measurement

2. Divided ounces by 5

3. Round the result to desired decimal places.

And don't just put this answer because I am not very sure.

1.875 pounds of dog food can be eaten by 5 dogs per day.

What information do we have?

Number of dogs = 5

Each dog eats per day = 6 oz

Total dog food eaten per day = Number of dogs × Each dog eats per day

Total dog food eaten per day = 5 × 6

Total dog food eaten per day = 30 oz

1 pound = 16 oz

So,

Total dog food eaten per day = 30oz / 16oz

Total dog food eaten per day =  1.875 pound

Answer:

315 (C)

Step-by-step explanation:

If it takes 45 minutes to make 3 bracelets, (considering she spends equal time on each) she's making 1 bracelet every 15 minutes. There are two ways you can solve this.

45/3 = 15 times 21 (bracelets) = 315

Or,

21/3 is 7, so multiply 7 and 45 to get 315 as well.

(Second Question) If we're finding percentages you always want to find a number out of 100. We can get to 100 evenly by multiplying 25 by 4. Do the same for 15 so the ratio stays equal, and you get 60, or: 60%.

Given:

Two cards are selected from a standard deck of 52 playing cards.

The first card is not replaced before the second card is selected.

To find:

The probability of selecting a four and then selecting a two.

Solution:

We know that,

Total number of cards = 52

Number of four cards = 4

Number of two cards = 4

Now,

[tex]\text{Probability}=\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}[/tex]

Probability of selecting a four = [tex]\dfrac{4}{52}[/tex]

After selecting a card, then number of remaining cards is 51.

Probability of selecting a two = [tex]\dfrac{4}{51}[/tex]

So, the probability of selecting a four and then selecting a two is

[tex]P=\dfrac{4}{52}\times \dfrac{4}{51}[/tex]

[tex]P=\dfrac{1}{13}\times \dfrac{4}{51}[/tex]

[tex]P=\dfrac{4}{663}[/tex]

Therefore, the required probability is [tex]\dfrac{4}{663}[/tex].

Answer:

Carol makes 6 more points then Abby.

Step-by-step explanation:

Since Abby made 2 three pointers, that means that she made 6 points in total (2x3). And since Carol made 4 three pointers, it means that she made 12 points in total (4x3). To find how many more points Carol made then Abby, you have to subtract the amount of points that Abby made from the amount of points that Carol made. Doing this, you will see that Carol made 6 more points then Abby.
