If
you would like to know how much baking powder is needed to make 3000 jumbo muffins, you can calculate this using the following steps:<span>
8 jumbo blueberry muffins ... 1 1/2 teaspoons of
baking powder
3000 jumbo muffins ...
x teaspoons of baking powder = ?
8 * x = 1 1/2 * 3000
8 * x = 3/2 * 3000
8 * x = 4500
x = 4500 / 8
x = 562.5 teaspoons
The correct result would be 562.5 teaspoons of baking powder.</span>
Direct variation is written in the form y = k * x or x = y * k. And, inverse variation is written in the form y = k/x or x = y/k.
For the first problem, if we isolated the y, we would get:
4y = 3x - 1
y = (3/4)x - 1/4
This is written as y = mx + b, which isn’t the form of direct or inverse variation, so the answer is NEITHER.
For the second equation, we could divide by 2 on both sides to isolate x and see if it is in the correct form:
x = 4/y
This is inverse form, so the second question is INVERSE with a constant of variation as 4.
The probability of getting a total that is a factor of 21 is 0.22
<u>Explanation:</u>
Factor of 21 is = 1, 3, 7, 21
Out of all the factors of 21, we cannot get 21 when the two die are rolled as the maximum sum that can be obtained is 12
The possible combinations are:
(1,2) (1,6)
(2,1) (2,5)
(3,4)
(4,3)
(5,2)
(6,1)
Total outcome = 6 X 6
= 36
Number of outcomes that is the factor of 21 is 8
The probability of getting a total that is a factor of 21 is 
p(21) = 0.22
Therefore, the probability of getting a total that is a factor of 21 is 0.22
