Answer:
Below.
Step-by-step explanation:
To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the rectangles.
So to find the number of students with grade U (< 160) it is:
120 * 0.2 + 40*0.5
= 24 + 20
= 44.
The number for Grade E
= (200 - 160) * 0.5
= 40 * 0.5
= 20.
The others can be found in the same way.
Answer:
5088
Step-by-step explanation:
The initial value of the car is $19340
The rate of decrease is 12.5%
The value of the car after 10 years is given by

Substitute the values to get;




To the nearest dollar we have $5088
The correct answer is choice C
The mean points of the team is the average points per game
Dom's claim is wrong
<h3>How to determine if Dom is right</h3>
The number of players in the team is:
n = 8
The mean score per game is:
Mean = 12
The mean of a dataset is calculated as:

So, we have:

Multiply both sides by 8

When Dom's point is removed, we have:


There are 7 players left.
So, the mean point is:


The mean score is not 10.
Hence, Dom's claim is wrong
