Answer:
1) 25.7% of the population is lactose intolerant.
2) 14% of the lactose intolerant people is Asian
Step-by-step explanation:
Population distribution according to race:
- 82% white
- 14% black
- 4% Asian
Lactose intolerance of races
- 15% of whites
- 70% of blacks
- 90% of Asians
Assume US population consists of 1000 people.
820 people are white, 140 people are black and 40 people are Asian.
Then 15% of 820 white, 70% of black, 90% of Asian is lactose intolerant.
- 15% of 820 is 123, which gives the white lactose intolerant people
- 70% of 140 is 98, which gives the black lactose intolerant people
- 90% of 40 is 36, which gives the Asian lactose intolerant people.
<u>Step1</u>
Then total lactose intolerant people in the US population is 123+98+36=257
Total population is 1000 people, therefore =25.7% of the population is lactose intolerant.
<u>Step2</u>
There are 36 Asian lactose intolerant people. Total lactose intolerant people is 257. = 14% of them is Asian.

Answer:
4/3
Step-by-step explanation:
Given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)

= 36/27
=4/3
