The table shows preferences of dancing or playing sports for male and female students:
GuDViN [60]

The conditional relative frequency for female students who prefer playing sports is 34%.

<h3>How to determine the statistic calculated?</h3>

The table of values is given as:

                        Sports   Dancing Row totals

Male students      18             16        34

Female students  18             35       53

Column totals       36            51         87

Mason's calculation is given as:

P = 21%

This is gotten by

18/87 = 21%

The above represents the joint relative frequency of female students who prefer playing sports.

To calculate the conditional relative frequency, he should divide 18 by the row total.

So, we have

18/53 = 34%

Hence, the conditional relative frequency for female students who prefer playing sports is 34%.

Q5. The ratio of boys to girls in a group is 7:1. If there are 48 more boys
Airida [17]

Answer:

There are 8 girls

Step-by-step explanation:

We see that right now there are 6 more boys than girls and if there were 2 girls there would be 14 boys meaning there would be 12 more boys than girls if you continue in this pattern you would get-

7:1= 6 more boys                   35:5=30 more boys                                                

14:2= 12 more boys                42:6= 36 more boys

21:3=18 more boys                 49:7= 42 more boys

28:4= 24 more boys               56:8= 48 more

This shows us that if there are 8 girls in  group there are 56 boys meaning there are 48 more boys than girls if the group had 8 girls

Simplify the following numbers
Mademuasel [1]

Answer:

177147

Step-by-step explanation:

3^{6} is the same as 3 times itself 6 times like 3x3x3x3x3x3 which is 729.

3^{5} is the same as 3 times itself 5 times and you probably know what that's like but it equals 243.

No all we have to do is do a little multiplying, which would be 729 x 243 getting the answer.

177147

Hope this helps and have a great day!
