Nga, Kai, and Jason volunteer in the school library. They want to find the average number of pages of a library book. It would b

e unreasonable to calculate the number of pages in every book to find the average. They decide they need to find a valid sample.
Inga suggests choosing 100 books from the history section to get a sample.

Kai suggests randomly selecting 100 books from the library’s entire catalog.

Jason suggests using 100 books from the teen fiction section to get a sample.

Who suggested the best way to produce a random sample that is not biased?

Assume that y varies directly with x, then solve.
Volgvan

Answer:

12

Step-by-step explanation:

y = kx

2⅔ = k(¼)

8/3 = k/4

k = 4×8/3 = 32/3

y = (32/3)x

y = (32/3)(1⅛)

y = (32/3)(9/8)

y = 3×4 = 12

3 times the measure of an angle is 14 less than the measure of its complement. What is the measure of the angle?
Sedbober [7]
Let the measure of the angle be x and from that the measure of its complement is 90 - x. The equation that best represent the given condition above is,
                            3x = (90 - x) - 14
The value of x from the equation above is 19. Thus, the answer is letter A.

Five divided by 8765
storchak [24]
That is mathematically impossible but maybe the other way around is possible. If you did 8765 divided by 5 you would get 1753. I hope this is what you want :)

Question 8 Multiple Choice Worth 1 points)
satela [25.4K]

Answer:

cos 0=90 degrees

Step-by-step explanation:

If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

\sin(90)  =  \cos(0)

and since sin 90 equal 1 cos of 0 equal 1.

What if we switch angles

Well they are still equal

\sin(0)  =  \cos(90)

But this time sin of 0 is 0 and cos 90 is 0.

A.T.Q

Applied force=800N

Area=0.2m²

Pressure=800/0.2=4000Pa
