Answer:

Step-by-step explanation:

Average Speed = Total Distance / Total Time

Total Distance = 50+ 70 + 10 + 60 = 190 Miles

Total Time = 1 + 1 + 1/2 + 1/2 =  3 hours

Average speed = 190 / 3 = 63.3 mph

A dilation is a transformation whose preimage and image are _____
Paha777 [63]

Answer:

proportional/noncongruant

Step-by-step explanation:

This is because when you dilate an image it changes size and that means the image is not congruent to the preimage but they will stay proportional since they keep the same shape.

  A health researcher is interested in comparing 3 methods of weight loss: low calorie diet, low fat diet and high exercise regi
vlada-n [284]

The weight loss in these three methods does not differ because the average weight loss is very similar in all 3.

<h3>How to calculate the average weight loss?</h3>

To calculate the average weight loss in these three situations, we must add all the values and divide the result by the number of values, for example:

  • 7 + 7 + 5 + 4 + 6 = 29
  • 7 + 8 + 8 + 9 + 5 = 37
  • 7 + 9 + 7 + 8 + 8 = 39

  • 39 ÷ 5 = 7.8
  • 37 ÷ 5 = 7.4
  • 29 ÷ 5 = 5.8

According to the above, it can be inferred that the hypothesis that the difference between one program and another is not significant enough to consider one plan more or less effective than another, because radically differences are not shown in each case.
