7. Which of the following relations is a function?A.{(2, 3), (-2, 3), (3, 2), (-3,-2)}
B.{(8,-4), (-4, 8), (-4, -8), (-8,4)}
C.{(9, -1), (-1, 9), (9, 2), (2, -1)}
D.{(5, -7), (4, 6), (-3, 8), (5,9)}

Answers

Answer 1
Answer:

A function means that each x can only have one y-value

B, C, and D are NOT functions because they have x-values that have multiple y-values.

For example

B. has two values for -4:

(-4, 8) and (-4, -8)

C. has two values for 9:

(9, -1) and (9, 2)

D. has two values for 5:

(5, -7) and (5, 9)

This makes A. the only function

Hope this helped!

If a/b = c/d , b ≠ 0, and d ≠ 0, then ad = ______ by the Means-Extremes Product Property.

Answers

(a)/(b)=(c)/(d)\nad=bc
(a)/(b)=(c)/(d) \ \ \ |* b \na=(bc)/(d) \ \ \ |* d \nad=bc

If a/b=c/d (b≠0 and d≠0), then ad=bc.

A soccer player boasts that he is able to kick a ball past 100 yards on 5 consecutive tries. You know that he's usually able to kick that distance 20% ofthe time. You create a model of how he kicks and run a simulation based on it, using (0 - 1) to represent his successes at kicking past 100 yards.

56421 88976 54893 20015 46504 98746 13210 77410

How many consecutive kicks past yards does the model show for the player?
A. 3 B. 2 C. 0 D. 1

Answers

Let 0-1 be successes and 2-9 be failures. Using the simulation, we get:

5642188976548932[001]546504987461321077410

Answer: 3

Step-by-step explanation:

Estimate the answer by rounding 863 x 534 to the nearest 100

Answers

Answer:

Step-by-step explanation:

If I rounded to the nearest hundred it would look like this 900 and 500.

because the closest hundred type number is 900 and the same for the number 500

Answer:

450,000

Step-by-step explanation:

To estimate the answer by rounding 863 x 534 to the nearest 100, follow these steps:

1. Multiply the tens digit of both numbers: 8 x 5 = 40

2. Round each number to the nearest 100: 863 ≈ 900 and 534 ≈ 500

3. Multiply the rounded numbers: 900 x 500 = 450,000

4. The estimated answer to the nearest 100 is 450,000.

Therefore, when rounding 863 x 534 to the nearest 100, the estimated answer is 450,000.
