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%).

Answers

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.

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

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1

New equation: 7 / 1

Simply the newer equation and you have your answer

7 ÷ 1 = 7 / 1 ➡️ 7

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

What is the area of the top of the water buoy as shown in the figure?

84.78 square in.
37.68 square in.
113.04 square in.
28.26 square in.

Answers

Answer:

The answer is 28.26 square in

Step-by-step explanation:

As, the diameter if the top = 6 inches

And the area of a circle = 3.14(pi) x radius^2

So here radius = Diameter /2 = 6/2 = 3

So radius = 3 inches

So area = 3.14 x (3)^2

= 3.14 x 9

= 28.26 square in

the answer is 28.26 square inch.
