30 girls who tried out for the lacrosse team Euclid middle school 12 were selected of the 40 boys Who tried out 16 were selected are the ratios of the number of students on the team to the number of students trying out the same for both boys and girls

Answers

Answer:

Yes, the ratio of the number of students on the team to the number of students trying out is same for both girls and boys.

The ratio is: 2:5

Step-by-step explanation:

It is given that:

Out of 30 girls who tried out for the lacrosse team Euclid middle school 12 were selected.

This means that the ratio of the number of girls on the team to the number of girls trying out is:

12/30=2/5

Also, 40 boys Who tried out 16 were selected .

This means that the ratio of the number of boys on the team to the number of boys trying out is:

16/40=2/5

Hence, we get that the ratio is same for boys and girls i.e. 2:5

12/30=2/5
16/40=2/5
The ratio is the same because they both simplify to 2/5

6. 2

Based on the table, what is the mean hockey score?

5.2

ANSWER

The mean hockey score is 3.2

Step - by - step Explanation

The data given is a frequency distribution table.

The mean is calculated using the formula,

$Mean = (\sum \:fx)/(\sum \: f)$

We obtain

$\sum fx$

by multiplying each score by the corresponding number of students and add the products as shown in the picture above

By substitution,

$Mean= (60)/(19)$

$Mean= 3.157$

Hence the mean hockey score is 3.2 to the nearest tenth.

Answer: 3.2

Step-by-step explanation:

Mean is sum of values, divided by number of examples.

If we write down score for each student, we will receive a long list of scores:

0,0,1,2,2,2,3,3,3,3,3,3,4,4,5,5,5,6,6

Now let's sum total scores achieved by students:

0+0+1+2+2+2+3+3+3+3+3+3+4+4+5+5+5+6+6 = 60

So sum of our values (scores) is 60.

Number of examples in our case is number of students, so, total number of students is:

2+1+3+6+2+3+2=19

So mean score in this group can be calculated as:

mean
