Answer:

Option C is correct

Step-by-step explanation:

Given that The owner of a movie theater wants to survey theater customers about their favorite types of movies.

If he surveys every 10th man that will not be a random sample and hence need not represent the population.

If only 25 teenagers are surveyed then opinion would be biased because of their age and will not represent the full population.

C) 50 randomly selected people leaving the movie theater

is the correct method of survey since 50 is a reasonable sample size for public going out from theatre and also all type of people are covered here.

D) 10 women waiting in line to buy movie tickets

is false because they are only women and also they are still waiting to get tickets.

So Option C is right.

The answer is length = 10 yd, width = 2 yd
proof
The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20

Where will her cut be located? Round to the nearest tenth. x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1 A

Arte-miy333 [17]

Answer:

The correct answer is 25.2 in.

Step-by-step explanation:

It is given that number line goes from 0 to 60 which can be used to represent a ribbon of length = 60 inches.

2 inches of the ribbon are frayed so actual length = 58 inches

Please refer to the attached image for the ribbon.

A is at 0

C is at 60

B is at 2

P is the point to divide the remaining ribbon in the ratio 2:3.

Part AB of the ribbon is frayed.

BP: PC = 2:3

Let BP = 2 $x$ and PC = 3 $x$

Now, BP + PC = BC = 58 = 2 $x$ + 3 $x$ = 5 $x$

So,

$5x =58\\\Rightarrow x =11.6$

BP = $2\times x = 2 \times 11.6 = 23.2\ inches$

Location of the Cut = 2 + 23.2 = 25.2 inches

Alternatively, we can use the formula directly:

$x = \dfrac{m} {m + n } (x_2 - x_1) + x_1$

$x_1 = 2\\x_2 = 60$

m: n is the ratio 2:3

$x = \dfrac{2} {2 +3 } (60- 2) + 2\\\Rightarrow 0.4 (58 )+2\\\Rightarrow 23.2+2 \\\Rightarrow \bold{25.2\ inches}$

Solve for θ if sinθ = 0.45. Round answer to the nearest degree.

marysya [2.9K]

If you look in a table of sines, you find that sin(θ) = 0.45 corresponds to an angle of about 26°45', so is nearest to 27°.
