Given:

The two ways table.

To find:

The number of girls in year 9.

Solution:

Using the two ways table, we get

Boys in year 10 = Total student in year 10 - Girls in year 10

= 256 - 123

= 133

Boys in year 9 = Total boys - Boys in year 10 - Boys in year 11

= 407 - 133 - 125

= 149

Girls in year 9 = Total students in year 9 - Boys in year 9

= 303 - 149

= 154

Therefore, the number of girls in year 9 is 154 and the correct option is C.

(6(1) = -5<br> 1) Find (4) in the sequence given by<br> (6(n) = b(n − 1) +9

Sloan [31]

Answer:

f(4) = 22

Step-by-step explanation:

I think that you type wrongly.

we have f(1) = -5

and f(n) = f(n-1) + 9

Find f(4)

Then

with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4

with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13

and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22

So f(4) = 22

Hope you understand.

What is the median please help please help

Paladinen [302]

Answer:

54.5

Step-by-step explanation:

To find the median, first we have to put the numbers in ascending/increasing order.

43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set

36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.

The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.

36, 43, 50, 50, 51, 58, 59, 60, 69, 73

51 + 58 = 109

109/2 = 54.5
