B, since to vary (vari) means to alter or change up. The inverse of something is the opposite.
Answer:
Step-by-step explanation:
first of all arrange this data from ascending to descending order.
11,15,15,15,16,17,18,19,20,22,23
use formula
N+1/4 (N means no of observations)
11+1/4
12/4
3 rd term
therefore Q1=15
Answer:
That cannot be the full question
Step-by-step explanation:
Answer:
degrees
Step-by-step explanation:
Sum of 3 angles in a triangle is 180..
The angles given are:
60
7x + 12
1
So we sum to 180 and write:
Also, straight angle is 180 degrees, thus Angle 1 and (14x + 9) angle is sum to 180, thus we can write:
Or we can write this as:
We substitute this expression for Angle 1 into 1st equation we got and solve for x first,
Since x = 9, the angle "14x + 9" would be:
14(9) + 9 = 135
Hence Angle 1 would be:
Answer:
<u>D) 8:15</u>
The first thing you do is add up all the apples which equals <u>15</u>. And then you see how many red apples there are which is <u>8</u>. Then you write your ratio which is <u>8:15</u>.
Your answer is <em><u>D) 8:15</u></em>
