Answer:

1.20%

2.Negative association

Step-by-step explanation:

1. There are 4 movies that are dramas with love interest out of 20 movies.

\frac{4}{20}  = 0.2

or 20%.

2. In the scatter plot, as x increases, y decreases so that means we have a negative correlation.

Joe went to the fair and tried his hand at the shooting gallery. He earned 20 points each time he hit the target but lost 50 poi
Lubov Fominskaja [6]
Answer: Joe hit the target 4 times.

Explanation: We can write this scenario as a system of equations.

Let’s express the number of times he hits the target with x.
Let’s express the number of times he misses the target with y.

“He earned 20 points each time he hit the target but lost 50 points when he miss. Joe ended the night with negative 470 points...”

20x - 50y = -470

“...after 15 shots.”

x + y = 15

Let’s write the whole system of equations.

20x - 50y = -470
x + y = 15

Let’s solve the second equation for y.

x + y = 15

Subtract x from both sides.

y = 15 - x

Let’s substitute y in the first equation with 15 - x.

20x - 50(15 - x) = -470

Distribute -50 among 15 and -x in the term -50(15 - x).

20x - 750 + 50x = -470

Combine like terms on the left side.

70x - 750 = -470

Add 750 on both sides.

70x = 280

Divide both sides by 70.

x = 4

Since we know that x = 4, we know that Joe hit the target 4 times.

2x+8= -16<br><br>3x-26= 10<br><br>sovle for x
Ksenya-84 [330]

2x + 8 = 16

2x = 16 - 8

2x = 8 (divide both sides by 2 to get x)

2x/2 = 8/2

x = 4

3x-26=10

3x=10+26

3x=36

X=12

How do you write 8.517 in a decimal form and word form?
vivado [14]
8.517 is already in decimal form. I’m pretty sure in word form it’d be eight and five tenths, 1 hundredths, and 7 thousandths.
