Answer:
a) 7 : 20
b)There will be 35 people with blue eye
Step-by-step explanation:
a)
This question is asking you the ratio of the number of people with blue eyes to the total number of people.
So seven people with blue eyes to the total number of 20 people.
7 : 20
b)
you got the ratio 7 : 20, this also means that there will be 7 people with blue eyes in every 20 people.
so you use 100 divides by 20, you will get the number five, this means there are 5 groups of 20 in 100 people.
so then you use 5 times 7, then you got the number 35.
That means, there are 35 people with blue eyes in 100 people.
Answer:
D
Step-by-step explanation:
To determine the roots equate the factors to zero, that is
(x + 2)(x² + 7x + 10) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x² + 7x + 10 = 0
(x + 2)(x + 5) = 0
x + 2 = 0 ⇒ x = - 2
x + 5 = 0 ⇒ x = - 5
roots are x = - 5 and x = - 2 with multiplicity 2
