Direct variation equal is written as : y = kx
K is the constant of variation.
12 = k4
12/4 = k
k = 3
y = 3x
Answer: <span>B. y = 3x </span>
Integers are like whole numbers, but they also include negative numbers so true
where
is the numbers of 1s, which is the same as the number of terms being summed in either
or
. It's easy to see what that number is from
; factoring a 2 from each term, you end up adding up the consecutive integers between 1 and 52, so
.
So
, and
.
Answer:
By using a simple formula - 2πr
Where,
π = 3.14
r = Radius of the Circle
(Check the image)
To calculate the average, we will use the following rule:
average = sum of scores / number of scores
sum of scores = 85+72+89+90 = 336
number of scores = 4
average = 336/4 = 84%
