Step-by-step explanation:

Step-by-step explanation:

Let the ratio of boys and girls be 5x and 7x

According to question-

no. of boys +no. of girls =total students

5x + 7x = 36

12x = 36

x = 36/12

x = 3

Therefore,

No. Of boys = 5x =5 * 3 =15

No. Of girls = 7x = 7 * 3 = 21

Answer:

There are 6 more girls than boys in a class of 36 with a boy ratio of 5:7

Step-by-step explanation:

5:7  where 5 + 7 = 12

therefore 12 x 3 = 36

3 x 5 = 15 boys

3 x 7 = 21 girls

21-15 = 6 more girls.

What is the median number for the numbers 4,8,10,5,9?
kumpel [21]
The median for a set of numbers would be the one that appears closest to the middle of the set.

For the set 4, 8, 10, 5, 9, in order to find the median, we must first sort them numerically.

4, 5, 8, 9, 10

Now, which of these 5 numbers is the closest to the middle?
The answer to that would be 8, since it is actually the number in the middle.

The median number for the numbers 4, 8, 10, 5, 9 is 8.

Answer:

Option a

Step-by-step explanation:

Given two normal distribution samples

I group has 106 as mean and 8.5 as std deviation with sample size = 60

II group has 121 as mean and 6.3 as std deviation with sample size =38

We find mean difference =-15

For margin of error finding, we have to find the combined std error for the difference

Variance of difference = Sum of variances

STd error for difference = 1.50

Hence for 99% margin of error =2.58(1.50)

= 3.87
