one of the ideas that you have explored in previous courses is how to describe a set of data. one of the ways that you may
have seen before is finding an average (also called a mean). read the math notes box for this lesson to review what a
mean is and how to find it. then find the mean for each set of data below. homework
2. jane's quiz scores: 82.64.73.91.85
b. the number of cats your teammates have as pets: 0.1.3.2
c. the number of minutes pam talked on the phone: 35.40, 12, 16, 25, 10

d

step-by-step explanation:

d

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
