<h2>Answer</h2>

It will take Carl 1.76 minutes to run 1.5 laps

<h2>Explanation</h2>

We know from our problem that Chris runs a lap in 1.17 minutes, so he will run half a lap in half the time:  \frac{1.17}{2} =0.585 minutes.

We have the time it takes Chris to run 1 lap and the time it takes him to run half (0.5) laps, so, to find how long it takes him to run 1.5 laps, we just need to add the two times:

Total time = 1.17 minutes + 0.585 minutes

Total time= 1.755

Since we need to round to two places, we check if the number after the 2nd place  is 5 or bigger; if it is, we add 1 to the number on the 2nd place. The number after the 2nd place is 5, so we add 1 to the 5 in the 2nd place to get:

Total time = 1.76 minutes

Carl will run 1.5 laps in 1.76 minutes

Andrei [34K]

Answer:

She wants to take unusually of the good and bad games into account

Step-by-step explanation:

Given that a basketball coach keeps track of the points scored per game for all of her players.  A trophy is given to the player with the highest mean score at the end of the season.

Mean vs median:

Mean is the arithmetic average of all the entries while median is the middle entry after arranging in ascending order.

Median is not affected by extreme items but mean is very much affected by unusually high or low scores.

Here since the trophy is decided to be given to the highest mean score it is obvious that

She wants to take unusually of the good and bad games into account

Because of this only, mean is taken instead of median.

Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x. 
 
                                      364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.

uysha [10]

Answer:


Step-by-step explanation:   emma's amount be X .  justin has $7.50+x because he has $7.50 more than emma.Since emma has 7.50+x-$12.to get everyones amount add what they have together which is=$7.50+x+$7.50+x-12 which in total is $63.00.after the calculations you get x=30.now distribute the x equally. so justin has $7.50+30=37.50.we also distribute it with emma's which is 7.50+30-12=25.5.

justin=$37.50

Emma=$25.50

to be sure add 37.50+25.50=$63
