Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
Answer:
I graphed the two points on a graph in the attachment! Hope this helps! :)
Step-by-step explanation:
Answer:
Number of births to women below 22 years of age: 830
% of births occurred to women of age between 34 and 36: 6.35%
Step-by-step explanation:
There are two parts to this question:
To calculate the number of births, we look at the histogram below.
We see that each bar has a number on top, suggesting that particular for the age limit. Number of births to women below age of 22, we start adding all numbers below the mark of 22 on x-axis:
⇒ 39+134+29+363 = 830
To calculate the percentage, we divide the number of births in that particular interval by total number of births and then multiply by 100.
To calculate the total number of births, we add all the numbers on the top of the bars:
⇒ 39+ 134+294+363+391+425+460+474+432+343+250+163+98+49+17+4+1 Total births = 3937

It would be 3 because you can divide all of them in to rows of three and still have the same kind of plants in each row.
