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

Referring to the table below, find the probability that a worker
contacted at random will be 35 - 44 years old. Express the answer as a
decimal rounded to the nearest hundredth and as a percent.

Answers

Answer:

A; .31 + 31%

Step-by-step explanation:

What I did: I put 17,172 over 55,208 as a fraction and to get the percentage I compared the denominator to 100, after this you multiply 17,172 by 100 then divide that by 55,208 to get 31.1316147 which rounds out to 31, once you put that over the 100 that is the percentage ( I may not have explained it the best way possible or the most efficient method, but thats how I got my answer ).


Here is what I did:


……17,172……………?…………….….17,172 x 100 = A
—————— = ————…………..A/55,208 = ? ...55,208………….100…………..…..(? = 31.1316147)

Step-by-step explanation:

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.

What is the value of −5 + |−18|?

A} 13
B}23
C} −13
D} −23

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

What will be the actual dimensions of Laurie’s garden?

Answers

The dimensions in ft will go from 8cm by 4cm to, 21.25ft by 10

1/2 is 0.5 as a decimal. So 8.5 multiplied by 2.5 is 21.25, 4 multiplied by 2.5 is 10.

Answer:

The length is 10 and the width is 21.25

Step-by-step explanation:

You time 2.5 × 4 = 10 to get the width

You time 2.5 × 8 = 20 and 1 half of 2.5 is 1.25.

So you add 20 + 1.25 = 21.25 and that is your width.

So the answer is length is 10 and width is 21.25
