Answer:
Your question was incomplete, as the values are not given.
I guess these are the values you are talking about.
Hair Type Brown Blond Black Red Totals
Wavy 20 5 15 3 43
Straight 80 15 65 12 172
Totals 100 20 80 15 215
Now w have to find out the probability of a child with red, straight hair.
Total no of children with straight hair are = 172
The children having straight red hair = 12
The probability of selected child = 12/172.
Answer:
The statement is wrong. a-b can be positive but not always.
Step-by-step explanation:
There can be three possible situations that are:
- a>b
- a<b
- a=b
Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3
In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3
In the third condition, the result will always be zero because both the integers will cancel each other. Such as 5-5=0
Answer:
The perimeter of the other polygon is
Step-by-step explanation:
we know that
If two figures are similar, then the ratios of its perimeter is equal to the scale factor
Let
z---> the scale factor
x----> the perimeter of the other polygon
y----> the perimeter of the larger polygon
so
we have
substitute and solve for x
