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:
undefined
Step-by-step explanation:
The slope is found by using the formula
The points are (1,4) and (1,-3)
m = (y2-y1)/(x2-x1)
= (-3-4)/ (1-1)
= -7/ 0
When we divide by 0 the answer is undefined
Answer:
The percentage increase in volume of the prism is impossible to find. This is because the current dimension or the diagram from which the dimension of the prism could be determined is not given.
However I will explain the methods to follow in finding this percentage increase, assuming that the current dimension of the prism is given.
Step-by-step explanation:
Assuming the volume the of prism is x ft³. After adding 1 ft to each dimension, the volume becomes y ft³.
The percentage increase = (y/x) × 100
= z%
That is,
Percentage increase = [(New volume) ÷ (Old volume)] × 100
The resulting value, z% is the percentage increase.
