The time between a flash of lightning and the sound of its thunder can be used to estimate the distance from a lightning strike. The distance from the strike is the number of seconds between seeing the flash and hearing the thunder divided by 5. Suppose you are 17 miles from a lightning strike. Write and solve an equation to find how many seconds there would be between the flash and thunder.

Answer:

No, the slope with the equation is 1/5 and the slope of the table is 2/1  or 2

Step-by-step explanation:

Slope is the change in y over the change in x.

Equation

y = mx + b when an equation is written in the slope intercept form of a line, the m is the slope.

y = [tex]\frac{x}{5}[/tex] - 3  can be writing

y = [tex]\frac{1}{5}[/tex] x - 3  It is easier to see that the slope is [tex]\frac{1}{5}[/tex]

Table

Look at the y's.  The are change by 2 each time.  Now, look at the x's.  They are changing by 1 each time.  So, the slope is:

[tex]\frac{2}{1}[/tex] or just 2

The slope with the equation is 1/5 and the slope of the table is 2/1 or 2

A team manager has to select a runner for the 100m sprint. He has two athletes in mind.
Here are the race times this season:

Athlete A - 14.2 14.8 13.8 15.1 14.1

Athlete B - 14.4 14.3 14.6 14.2 14.5

Using an appropriate average, determine which athlete the team manager should select for the 100m race.

Answers

Answer:

Whichever athlete the team manager chooses does not matter

Step-by-step explanation:

Athlete A Average = 14.4

Athlete B average = 14.4

Both athletes have the same average so it would not matter who is chosen for the 100m race

Answers

Absolute value makes the number positive, so now you have -5+18, then adding a negative to a positive is the same as subtracting. Therefore, 18-5=13. Answer should be A}
-5 + 18 = 13 A because the absolute value cancels out the negative on the 18 meaning you could just take away 5 from 18 leaving you with 13

Answer:

Step-by-step explanation:

nyjnnndd

Given statement solution is :- The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.

To find the median of the given data set, we need to arrange the values in ascending order:

0, 0, 1, 2, 3, 4, 4, 5, 7, 8

The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.
