hope this helps have a great day/night!!! :))
To find the percentage,we need to form a fraction first:
The nominator would be: the students who have not blue eye and were not wearing orange at the same time (50)
The denominator: students with not blue eyes (20)
Hence we can form the fraction: 20/50
To find the percentage, we can multiply the fraction by 100%:
20/50x100%
=2/5 x 100%
= 200/5 %
= 40%
Therefore the answer is 40%.
Hope it helps!
Answer:
x=±1. are the factors of the quadratic equation.
Step-by-step explanation:
Given quadratic expression, f(x)=-12x - 2x + 60x² +14x-60
Rearranging and adding the terms in the expression and equating to zero.
f(x)= 60x² -60=0
60(x² - 1) =0
The zero product property states that if the product of a⋅b=0 then either a or b equal zero or both of them must be equal to zero. This basic property helps us solve the quadratic equations like (x+2)(x-5)=0 where x =-2,5.
from the zero product property we can infer that 60≠0⇒x² - 1=0
⇒(x+1)×(x-1) = 0
⇒x=±1.
Therefore, x=±1. are the factors of the quadratic equation.
Answer:
A) 2 2/3 pages per hour
Step-by-step explanation:
You would multiply 1/4 times 4 to get 1 hour
then you would multiply 2/3 times 4 which is 2 2/3
Answer:
-20,2m-11,8
Step-by-step explanation:
rewrite it
2y+14,6m+3,8-(34,8m+15,6-2y)
remove the opposites
and then simplify
-20,2m-11,8
im not sure if this makes sense
