Answer:

x is 37° and y is 97°

Step-by-step explanation:

${ \tt{x + 23 \degree = 60 \degree}} \\ { \tt{x = 60 - 23}} \\ { \tt{x = 37 \degree}}$

${ \tt{y + 23 \degree = 120 \degree}} \\ { \tt{y = 120 - 23}} \\ { \tt{y = 97 \degree}}$

Answer:

x=23, y=157

Step-by-step explanation:

23 and x are on equalivent sides of the rhombus so they are equal. To solve for y you have to multiple 23 by 2. Getting 46 you subtract that from 360 to get 314. Dividing 314/2 you get 157.

the angle theta is located in quadrant 1 and cos of theta is 3/8. what is the value of sin of theta ?

ra1l [238]

Answer: sin of theta = (√55)/8

Step-by-step explanation:

Cosine is the x-value divided by the hypotenuse. We now know that since cosine is 3/8, that the hypotenuse is 8. In order to find the third side of the triangle (which would be the v-value), we must use Pythagorean theorem. The third side is square root 55. Sine equals the y-value divides by the hypotenuse. We know both of those values, so Sine of theta = square root of 55 divided by 8.

9/10 ÷ 5/10<br> can you please explain?

frozen [14]

Answer:

Step-by-step explanation:

Hello,

Dividing by 1/2 is like multiplying par 2, right ?

Dividing by 5/10 is like multiplying par 10/5, right ?

and then

$\dfrac{\dfrac{9}{10}}{\dfrac{5}{10}}=\dfrac{9}{10}\times \dfrac{10}{5}=\dfrac{9}{5}$

as 10/10=1

Thanks

Suppose the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes. W

butalik [34]

Answer:

C) Uniform distribution

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.

We can calculate the probability.

Uniform probability distribution

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformily distributed over a 90 minute interval, that is, between 0 and 90, so $b = 90$ and $a = 0$ .

We want to find $P(X \leq 15) = \frac{15-0}{90-0} = 0.167$
