Answer: 14 meters

Step-by-step explanation:

Use the pythagorean theorem to solve.

12 ² + 8 ²= c ²

208= c ²

√ 208 = √ c ²

14.42= c

14 meters

Silvia wants to buy a car that costs $9,768.00. She deposits $6,600.00 into a savings account that pays simple interest at a rat
ozzi
Comparing the cost of the car to the deposit, $3,168.00 the amount required to be added to the deposit
$3,168 is the interest
rate = 8%
time = T
principal = 6,600.00
I = ( PRT)/100
T = 100 I/PR
=(100*3168)/(6600*8)
= 6
She should leave the money for six years.

American kestrels live in More Mesa near your professor’s house. Suppose that there are 100 birds, of which a random sample of s
Ulleksa [173]

Answer:

P(X=3) = 0.2013

Step-by-step explanation:

After taking and tagging the first 20 birds, then we have a proportion of 20% of tagged birds within the population, that is

p=\frac{n}{N}

p=\frac{20}{100}=0.20

Supposing that the probability (0.20) of capturing a bird <em>remains constant</em>, we may resolve it as it follows:

Capturing 10 birds can be considered as a binomial experiment with a success probability p = 0.2

Let, P(X=x)=nCx*p^{x}*(1-p)^{n-x} be the expression of the binomial distribution, for our case we have:

p=0.2

x = 3

n=10

Then,

P(X=3)=10C3*0.2^{3}*0.8^{10-3}

P(X=x)=0.2013

Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%
