Let’s say we want to find the size of a deer population. Suppose that we capture 80 deer, tag them, and release them back into t

he forest. After some time has passed—allowing the marked deer to thoroughly mix with the rest of the population—we come back and capture another 100 deer. Out of these deer, we find that 20 are already marked. Using this information, what can you estimate the deer population to be?
A. 1,000
B. 400
C. 200
D. 800
E. 600

Answer:

400

Step-by-step explanation:

20/100 = 80/x

Cross multiply and divide

100 X 80 = 8000 / 20 = 400

( x_{1} , y_{1} )

( x_{2} , y_{2} )

rate of change or slope m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{rise}{run}

y = mx + b

"b" is y-intercept

A deer population is estimated to be 4,350. The growth rate of the population is given by the equation y=4350(1.07) . What is th
HACTEHA [7]

Answer:

Step-by-step explanation:

Analyzing the growth rate of 1.07:

If the growth rate is a number greater than 1, we have exponential growth; if the growth rate is a number greater than 0 but less than 1, we have exponential decay.

Our growth rate is actually growth.  But the rate of growth is not 107%.  The rate of growth means that we already had 100% of the population and that it is growing by 7% each year.  100% + 7% = 107%; as a decimal, 1.07

So the rate of growth is 7%

A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fai
azamat

Answer:

Probability (Both fail)  = 0.001369

Probability (None fails) =0.927369

Probability (at least one fails)   = 0.072631

Step-by-step explanation:

given data

Probability (fail) P = 0.037

two alternators is  independent

solution

we get here first  probability that both will fail will be

Probability (Both fail) = 0.045²    ................1

Probability (Both fail)  = 0.001369

and

now we get probability that neither will fail

Probability (None fails) = (1-0.037)²              ...............2

Probability (None fails) =0.927369

and

now we get probability that at least one fails

Probability (at least one fails)  = 1 - Probability (non fails)     .................3

Probability (at least one fails)   = 1 - 0.927369

Probability (at least one fails)   = 0.072631
