Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
we have the points (2,14) and (4,28)
Find out the constant of proportionality k
For (2,14) ---->
For (4,28) ---->
so
the value of
therefore
The equation is
When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
Answer:A
Step-by-step explanation: Add the 1s first, you get 3, then add 3/8 and 5/8 and you Get 1. 3 +1 is 4 plus the remainder of 1/8
Answer:
1/3
Step-by-step explanation:
add all of the totals including the missing pair
we now have 24
7+1 is 8
24 minus 8 is 16
24 can be split into 2 groups of 8
and we have 2/3 left. which makes our solution 1/3
