Answer:

x = 22, y = 20

Step-by-step explanation:

well 66 and 2x-22 are corresponding angles so those are congruent so you set that up like 2x - 22 = 66 to find x and for y 66 and 5y + 14 are supplementary angles so they equal 180 so you set that one up like (5y + 14)+ 66 = 180 and then its just basic math

Answer:

$\boxed {\boxed {\sf z=2.2}}$

Step-by-step explanation:

The z-score tells us how many standard deviations a value is away from the mean.

The formula is:

$z=\frac{x- \overline{x}}{s}$

where x is the value, $\overline {x}$ is the mean, and s is the standard deviation.

We want to find the z-score for the score of an 83, the mean is 72, and the standard deviation is 5.

$x=83 \\\overline {x}= 72 \\s=5$

Substitute the values into the formula.

$z=\frac{83-72}{5}$

Solve the numerator.

$z=\frac{11}{5}$

Divide.

$z=2.2$

The z-score is 2.2, which means the score of 83 is 2.2 standard deviations above the mean.

Determine whether the events are independent (I) or dependent (D). Place your answer in the blank provided. 1. Ramiro draws a ma

Stels [109]

Answer:

Independent events

Step-by-step explanation:

Given that:

Ramiro draws a marble from a jar without replacement and then flips a coin

Let $E_1$ be the event that Ramiro draws a marble without replacement and;

Let $E_2$ be the event of flipping a coin.

Let's have an analogy so that we can better understand the concept of independent and dependent events.

Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.

The event $E_1$ does not in any way affect the event $E_2$ of a head or a tail showing up in a flip of a coin.

Therefore, we say that $E_1$ and $E_2$ are independent events.

Suppose the event $E_1$ affects or influence the event $E_2$ , then we can say they are dependent events.
