Answer:

B-

point s

Step-by-step explanation:

I just did the quiz, this is the correct answer

Point S is the endpoint of the rays.

Option B is the correct answer.

What is a ray?

In geometry, a ray is a straight line that starts from a specific point (called the endpoint) and extends infinitely in one direction.

A ray can be thought of as a part of a line that has one endpoint and continues indefinitely in one direction.

We have,

A ray is a line that starts from a specific point and extends infinitely in one direction.

The starting point of the ray is called the endpoint, and the other end of the ray extends indefinitely.

Therefore, a ray does not have an endpoint in the direction it extends, but only at its starting point.

From the figure,

The ray SR, SU, and ST have one common starting point.

i.e Point S.

Thus,

Point S is the endpoint of the rays.

Find the mode and the mean of the following set showing number of hours of operating life 25 flashlight batteries:20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.

Answers

Answer:

mode: 22

mean: 21

Step-by-step explanation:

For mode, look for the number that occurs the most (22). I remember this because MODE kinda sounds like MOST. Remember that the mean is just another word for average. I remember this because I think its MEAN that they'd make another word for average, although the term average is way easier to remember. So, add all numbers (525) and divide them by 25.

525 divided by 25= 21

(it might be safe to double check my work)

The mean of the set showing number of hours of operating life 25 flashlight batteries is, 21.8

The mode of the set showing number of hours of operating life 25 flashlight batteries is, 22

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The set showing number of hours of operating life 25 flashlight batteries is,

⇒ 20, 21, 19, 22 , 18 , 23 , 25 , 22 , 23 , 20 , 23 , 20 , 22 , 21 , 24 , 21, 22 , 23 , 19, 21, 22 , 22 , 24 , 26 , 22.

Now, We can arrange the numbers in ascending order as;

⇒ 18, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 22, 22, 22, 22, 22, 22, 23, 23, 23, 23, 24, 24, 25, 26

Thus, The mean of the set is,

⇒ Mean = 18 + 19 + 19 + 20 + 20 + 20 + 21 + 21 + 21 + 21 + 22 + 22 + 22 + 22 + 22 + 22 + 22 + 23 + 23 + 23 + 23 + 24 + 24 + 25 + 26 / 25

⇒ Mean = 545 / 25

⇒ Mean = 21.8

And, The mode of the data set is the most often number in data set.

Hence, The mode of the set = 22

Let n be equal to 156% of 70. Which of the following proportions is true?

Answers

Answer:

156/100=n/70

Step-by-step explanation:

1.56/70=109.2

156/100=1.56

109.2/70=1.56

as far as im concerned 1.56 and 1.56 is equal lol

The true property is (156/100) = (n/70).

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Given that n is equal to 156% of 70

n=156% of 70

n=156% × 70

n= (156/100) × 70

(n/70) = (156/100)

Or, (156/100) = (n/70)

Hence, the true property is (156/100) = (n/70).

help me answer this question in the picture :)))

Answers

Answer:

x = 15p

-75

Explanation:

remove brackets:

4px + 4 = 64

solving for x --> 4px = 64 - 4 then--> 4px = 60

then diving both sides by 4p --> x = 60\4p --> x = 15p

now solving for x when p is -5

we will substitute the -5 in the equation we got --> x= 15 (-5)

which will give us --> x = -75

4(px + 1) = 64
The value of x in terms with p is: 3.
The value of x when p is -5 is: -3

Explanation: 64 divided by 4 equals to 16. So whatever p and x are has to equal to 15 (because there’s a +1). So it’s naturally be 5 times 3 which is 15. P standing for 5 and x standing for 3. The first one just asks what x is, and it’s 3. And the second one asks what x would be if it was -5 instead of 5. So naturally it would be -3 because a negative times a negative is a positive and the answer we have is a positive. The first answer is 3 and the second is -3.

Answers

Answer:

Step-by-step explanation:

This question has to deal with approximation.

We have:

[tex]Men = 29867[/tex]

[tex]Women =16928[/tex]

To get the required answer, we have to approximate the given parameters.

For men, we have:

[tex]Men = 29867[/tex]

[tex]Men =30000[/tex]  -- Approximated

For women, we have:

[tex]Women =16928[/tex]

Juan read 300 pages in 5 days and Jose read 150 pages in 3 days are these reading rates equivalent

Answers

Answer:

No, they aren't equivalent.

Step-by-step explanation:

First divide 300 by 5 to figure out how many pages he read in each day.

That would be 60 pages each day.

Then, divide 150 by 3.

That would be 50.

Since 60 ≠ 50, the reading rates are not equivalent.

Hope I helped :)

Answer:

No.

Explanation:

If you divide 300 by 5, you get Juan's reading rate which is 60 pages per day. If you divide 150 by 3, you get Jose's reading rate which is 50 pages per day. Their reading rates are not equal.

First, we have to find the t value in Jumel’s equation that will get him $75. So our equation is 75=60+0.05t. Then solve for your t value (subtract 60 from each side, divide by 0.05). You should get 300 as your t value. After this, just plug 300 into Ashley’s equation to find the cost. Your answer should be $150

Part C: Because both the equations are linear, both plans will cost the same at the point of intersection on a graph. This is where a certain t value for equation will produce the same c value, or cost
