Step-by-step explanation:

Answer:

Step-by-step explanation:

x-2y = 2

-x+2y = 2

set 1st eq. equal  to 2nd equation since they both equal 2

x -2y = -x + 2y

2x = 4y

x = 2y

1/2x = y

(x, 1/2x )    :P

Answer:

I can't understand

Step-by-step explanation:

I will just try to rewrite your question so someone lese can answer it.

"What is the probability of a chance event, with a probability of 0.05, to happen when compared to a chance event with a probability of 0."

or just what is the probability(how high or low are the chances) of an event with a very low chance of happening when compared to an event that can never happen.

Answer:

Step-by-step explanation:

to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.

A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)

B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis

Answer:  M=2.4R

Step-by-step explanation:

If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...

24/10=2.4

so now we can set up our equation...

M=2.4R

this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.

Answer:

Book of 240 pages has 12 booklets in total

Book of 160 pages has 8 booklets in total.

Total booklets both the books have in total = 20

Step-by-step explanation:

Given - There are two books: one of 240 pages and the other of 160 pages. If the 2 books are made up of booklets with the same number of pages (between 16 and 28),

To find - How many booklets do the two books have in total?

Proof -

Given that, Number of pages of a booklet is between 16 and 28.

So, The number that lies between 16 and 28 will have to divide the number of pages of both the books.

(Because given that both the books are made up of booklet with the same number of pages)

By inspection, we get

The number of pages of a booklet = 20

because

240/20 = 12 and 160/20 = 8

∴ we get

1 booklet = 20 pages

i.e.

20 pages = 1 booklet

⇒1 page = [tex]\frac{1}{20}booklet[/tex]

⇒240 pages = [tex]\frac{240}{20}booklet[/tex] = 12 booklet

So, we get

The book of 240 pages has 12 booklets in it.

Now,

1 page = [tex]\frac{1}{20}booklet[/tex]

⇒160 pages = [tex]\frac{160}{20}booklet[/tex] = 8 booklet

So, we get

The book of 160 pages has 8 booklets in it.

∴ we get

Book of 240 pages has 12 booklets in total

Book of 160 pages has 8 booklets in total.

So, Total booklets both the books have = 12 + 8 = 20

Answer:

Step-by-step explanation:

Rounded volume: 524 cubic inches.

Step-by-step solution:

The formula for the volume of a sphere is:

Where r is the radius of the sphere.

The radius is half the diameter, therefore it is r=10/2=5

We plug it into the formula and we get:

Then we get:

If we do it in our calculator we get 523.599 that rounded to the nearest whole is 524 cubic inches .

Step-by-step explanation:

Answer:

We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.

Step-by-step explanation:

We are given;

Population mean; μ = 30 minutes

Population standard deviation; σ = 3 minutes

Sample size; n = 10

Sample mean; x¯ = 25

Significance level = 5% = 0.05

Let's define the hypotheses;

Null hypothesis; H0: μ = 30

Alternative hypothesis: Ha: μ ≠ 30

Let's find the test statistic;

z = (x¯ - μ)/(σ/√n)

z = (25 - 30)/(3/√10)

z = -5.27

From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;

p < 0.00001

This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.

Answer:

A. Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
