Answer:

x = 17.6

Step-by-step explanation:

use sine

⇒ sine = $\frac{opposite}{hypotenuse}$

⇒ sine 62 = $\frac{20}{x}$

sine of 62 is 0.88

⇒ 0.88 = $\frac{20}{x}$

multiply 20 on both sides

⇒ 0.88 x 20 = $\frac{20}{x}$ x 20

⇒ 17.6 = x

58 divided by 7 What is the remainder in fraction form

Maru [420]

Since 7*8= 56 if you divide 58 by 7 you would get 8 with a remainder of 2. The remainder goes over the divisor so it would be 8 and 2\7

PRECAL Find the compliment of 0.25 Find the supplement of 7π/8

balandron [24]

The unit of measurement is not specified, so for the sake of this problem, we'll assume it's radians (If you need it in degrees, I'll be happy to edit).

Find the compliment of 0.25:

Complementary angles add up to 90 degrees. In radians, this would be π/2. If you're unsure how I got this, check degrees to radian conversions.

The compliment of 0.25 would be $\dfrac{\pi}{2} - \dfrac{1}{4}$ (1/4=0.25)

$\dfrac{\pi}{2} - \dfrac{1}{4}$

$= \dfrac{\pi}{2} - \dfrac{1}{4} = \dfrac{2\pi-1}{4}$

(This is the simplified form in case you're homework needs it in this form)

That's the compliment. In decimal (rounded to the nearest hundredth), this would be 1.32 radians.

Find the supplement of 7π/8:

Supplementary angles add up to 180 degrees. In radians, this would be π.

The supplement would be the following:

$\pi- \dfrac{7\pi}{8}$

$=\dfrac{8\pi}{8}-\dfrac{7\pi}{8}=\dfrac{\pi}{8}$

Thus, the supplement is π/8 radians. If any of this struck you as confusing, comment and I'd be happy to clarify.

At a restaurant a manger recorded the sales for one of his servers named

TiliK225 [7]

Answer: b. Damarias median sale is $52

Step-by-step explanation:

Hi, the correct option is b. Damarias median sale is $52.

If we rank the sales order from lowest to highest

28 46 48 48 52 52 59 60 71 192

Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

Feel free to ask for more if needed or if you did not understand something.

69. A statistics instructor believes that fewer than 20% of Evergreen Valley College (EVC) students attended the opening midnigh

Oduvanchick [21]

Answer:

a. at least 20%, when in fact, it is less than 20%.

Step-by-step explanation:

Type 1 Error is to reject null hypothesis when it is actually true.

Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.

In mathematics fewer than 20% means less than 20%.

So the null hypothesis is that less than 20 % students attended the show.

We have to reject this hypothesis .

We can reject this hypothesis when we assume that the % is greater than or equal to 20 %

At least 20% means greater than or equal to 20%.

So the best choice is option a.

at least 20%, when in fact, it is less than 20%.
