Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500
Answer:
8 books
Step-by-step explanation:
Earning for each ticket is $0.25 and for each book is $2
If total earning for 4 tickets and x books is $17, then the equation is:
- 0.25*4 + 2x = 17
- 1 + 2x = 17
- 2x = 16
- x = 16/2
- x = 8
So Molly purchased 8 books
9,-2 because i used to always get confused but i’m not sure that’s the right answer
P(x)=-15+7/4=-2
P(y)=12-4/4=2
P=(-2,2)
