Answers

Answer:

25 minutes

Step-by-step explanation:

median before = 53

median after = 28

53-28 = 25

Other info

The median marks the mid-point of the data and is shown by the line that divides the box into two parts (sometimes known as the second quartile). Half the scores are greater than or equal to this value and half are less.

The difference of the set of median shown = 25 minutes.

the answer is 25 53-28=25.

Answers

The first question. 7/24

Explanation: first you need to get the fractions to the same denominator so you use lowest common multiples
The lowest common multiple of 8 and 3 is 24 so you times both 3 and 8 by 3 giving you 9/24 and then you times both 1 and 3 by 8 giving you 8/24
When you add these together you get 17/24 so the rest of that would be 7/24

Eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily:

A scatter plot is shown with the title Lemonade Sales. The x-axis is labeled High Temperature, and the y-axis is labeled Cups of Lemonade Sold. Data points are located at 30 and 4, 40 and 6, 40 and 8, 50 and 2, 55 and 10, 65 and 14, 70 and 16, 75 and 14, 85 and 19, 90 and 20.
Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade sold. (2 points)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept. (3 points)

Answers

Answer:

The answer for part A: If the city is hotter in temperature more people will want the cold refreshing lemonade.

Part B: The line of best fit is a line that will have the same amount of point on each side so you should draw a straight line and then make sure it has the same amount of point on each side. To calculate the slope use Y2-Y1/X2-X1, Y-intercept is the point that intercepts the Y-intercept.

Step-by-step explanation:

Part A: Because if it is hot outside you will sweat more being less hydrated which is why more people would want a drink especially lemonade.

Answers

4x - 8 + 4y

Hope this is right

Answer:

4x - 8 + 4y

Step-by-step explanation:

When an expression inside a pair of brackets is multiplied by a value, all you need to do is multiply each term inside the brackets by that coefficient:

4(x - 2 + y)

= 4 × x - 4 × 2 + 4 × y

= 4x - 8 + 4y

The complement of angle M is 10 degrees. What is the measure, in degrees, of angle M?

Answers

Complementary angles add up to 90 degrees.

Let x = complement of angle M is 10 degrees.

We want to solve x + M = 90.

Let's solve for M.

10 + M = 90

M = 90 - 10

M = 80.

The measure of angle M is 80 degrees.
