Every weekend Jill bikes 7.5 miles from home to the tennis court. His cousin Jun does the same thing. He bikes 80% as far as Jill. How many miles does Jun bike from home to the tennis court every weekend?Please show how you got your answer.

Answers

80% of 7.5 is 6.
so if he travelled 80% further, it would be 7.5+6 which is
13.5

Answer:

53.2

Step-by-step explanation:

MY REASONING FOR THIS IS BECAUSE 80% of 9.5= 7.6 and because a weekend has 7 days then you have to multiply 7.6*7 which is 53.2.

The answer is 420.

Step-by-step explanation:

Because since we know it wants 140 grams of fish. And twice as many pasta than fish. You can simply just do this: 140 x 2 = 280. So 140 + 280 will = 420. There you go!

420 grams
Do 140 x 2 to get the pasta (double the fish) to get 280. Then add the grams of fish back 280 + 140 which equals 420 grams

Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Answers

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
