A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist
vladimir2022 [97]

Answer:

0.25 miles per minute, travels 5 miles in 20 minutes

Step-by-step explanation:

First, we have to find out how many miles he can travel in a minute.

We know that he travels 15 miles every hour, and we know that one hour is 60 minutes.

  • 15 mi./ 1 hr = 15 mi. / 60 minutes

So, we can divide 15 miles by 60 minutes in order to get his pace for miles per minute

  • 15 ÷ 60 = 0.25 miles per minute

Then we can just multiply 0.25 miles by 20 minutes

  • 0.25 × 20 = 5

which gives us 5 miles in 20 minutes

The dot plots show 9 scores on a 10 question trivia game for two students. Select all the statements that must be true.
Burka [1]

Answer:

The correct statements are b, c and e.

Step-by-step explanation:

Consider the dot plot for Noah and Jada's score in the trivia game.

From the dot plot it is quite clear that the data form a bell-shaped curved or a normal curve.

For the normal distribution:

Mean = Median = Mode

Noah's mean score = 5

Jada's mean score = 3

The standard deviation of a data set is the measure of dispersion of the observations of that data set from their mean.

On closely studying the graphs we can see that the Noah and Jada's scores are almost at a same distance from the mean, i.e. the spread of Noah's score is same as the spread of Jada's score.

So, the correct statements are:

b. The standard deviation of Noah's scores is equal to the standard deviation of Jada's scores.

c. The mean of Noah's scores is greater than the mean of Jada's scores.

e. Using only Noah's scores, the mean is equal to the median
