Let x=number 1 let y=number2
there sum is equal to 70
then
number1+number2=70
substituting
x+y=70
y=70-x
let there product will be p
p=xy
substituting
p=x(70-x)
which is choice c
Answer:
Step-by-step explanation:
There's only 1 '6' on an ordinary die with 6 sides, so the probability of rolling a 6 is 1/6.
That of NOT rolling a 6 is the complementary probability: 1 - 1/6 = 5/6.
Answer: the length is 36 meters. The width is 12 meters
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the length of the rectangle.
There's a rectangle that's drawn with a length that is three times the width. This means that
L = 3W
The area of a rectangle is expressed as L×W. If we know that the area of the rectangle totals to be four hundred thirty two square meters, it means
LW = 432 - - - - - - - 1
Substituting L = 3W into equation 1, it becomes
3W×W = 432
3W^2 = 432
W^2 = 432/3 = 144
W = √144
W = 12
L = 432/W = 432/12 = 36
To find the percentage divide the colums with yes by the total column and divide the columns with the no by the total columns
also divide the men (both yes and no) numbers by the totals
