What is the mean and median???

Answers

Answer:

average amount=mean.  middle number=median

Step-by-step explanation:

The mean is a type of average. It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. ... Then divide the sum by how many values there are. So if you have five values, add them all together, then divide the result by five. That is the mean.

The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above

Answer:

median: 25  |  mean: 24.9

Step-by-step explanation:

(21+22+22+24+25+25+25+25+26+26+26+27+27+28)/14 = 349/14=24.9

21  22  22  24  25  25 25  25  26  26  26  27  27  28

25 are the middle numbers when they are put in order, and therefore 25 is the median. (average of 25 and 25 is 25.)

Solve the inequality: m/2 - 1 > 7 *

Answers

Answer:

m > 16

Step-by-step explanation:

m/2 - 1 > 7

Take the - 1 to the other side so that it becomes positive and adds onto 7 to become 8

m/2 > 7 +1

m > 8 x 2

Multiply both sides by 2 so you would get 8 x 2 to receive 16

m > 16

m/2 - 1 > 7

m/2 > 7 + 1

m/2 > 8

m/2 • 2 > 8 • 2

m > 16

Write the equation of the following line in slope-intercept form

Answers

Answer:

y = 2/5x + 4

Step-by-step explanation:

Points on the line:

(0,4) and (5,6)

Slope formula:

m=(y2-y1)/(x2-x1)

m=(6-4)/(5-0)

m= 2/5

y - y1 = m(x - x1)

y - 4 = 2/5(x - 0)

y - 4 = 2/5x

y = 2/5x + 4

y= 2/5x +4 ; that is the equation

The average distance from the Sun to the Earth is 1.5 × 10^11 meters and the speed of light is 3 × 10^8. If distance = rate times time, how many seconds on average does it take for the Sun's light to reach Earth?

Answers

Answer:

1.503⋅10^11

light years

The time taken for the Sun's light to reach Earth is t = 5 x 10² seconds

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed be represented as S

Now , the value of S is

S = D / T

where , the distance D = 1.5 × 10¹¹ meters

S = 3 × 10⁸ m/s

And , T = D / S

On simplifying , we get

Time taken T = 1.5 × 10¹¹ / 3 × 10⁸

T = 0.5 x 10³

T = 5 x 10² seconds

Hence , the time taken is T = 500 seconds
