Answer:
85%
Step-by-step explanation:
There are two ways to solve this.
1. You can find the percent of birds, and then subtract that from 100%.
To find the percent of birds, divide 45/300 or make the denominator 100 by dividing both parts by 3.
45/300 (as a fraction)
=15/100
That is the same as 15%.
Subtract that from 100% and you get 85%.
2. You find the number of non-bird animals and make that a percent.
300-45=255 non-bird animals
255/300 (as a fraction)
=85/100
That is the same as 85%.
So either way, the answer is 85%.
Answer:
(820 ; 980)
Step-by-step explanation:
Given :
Sample size, n = 80
Number of bilingual from sample = 36
Sample proportion, phat = x / n = 36 / 80 = 0.45
Margin of Error = 4% = 0.04
Interval = sample proportion ± margin of error
0.45 ± 0.04
(0.41 ; 0.49)
(0.41 * 2000 ; 0.49 * 2000)
(820 ; 980)
Answer:
m= 1/3
Step-by-step explanation:
to find slope: y2-y1/ x2-x1 so,
3-2/4-1= 1/3
