Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3

Answers

Answer: C: 4

Step-by-step explanation:

The domain of the function f(x) is: -6 < x ≤ 4, and the value that is in the domain of the function f(x) is 4

How to determine the value in the domain?

The function is given as:

f(x) = 2x + 5,   -6 < x ≤ 0

f(x) = 2x + 3,   0 < x ≤ 4

The above means that the domain of the function f(x) is:

-6 < x ≤ 0 and 0 < x ≤ 4

When combined, we have:

-6 < x ≤ 4

This means that x is greater than -6 but does not exceed 4

Hence, the value that is in the domain of the function f(x) is 4

Answer: -1

Step-by-step explanation:

-8 (-8x - 6) = -6x - 22

distribute

64x + 48 = -6x -22

get rid of the smallest x by adding 6x to both side

70x + 48 = -22

minus 48 to both sides

70x = -70

divide both side by 70

x = -1

X = -1

The dot plot shows predictions for the winning time in the 200-meter sprint. The winner finished the race in 22.3 seconds. What is the greatest percent error among the predictions?

Answers

Answer:

3.2%

Step-by-step explanation:

Answer:

The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Step-by-step explanation:

Given that,

The dot plot shows predictions for the winning time in the​ 200-meter sprint.
The winner finished the race in 22.5 seconds.

We have to determine,

What is the greatest percent error among the​ predictions.

According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds. 

Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)

Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).

Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).
