Answer:
0.4
Step-by-step explanation:
Use the formula for conditional probability.
P(B|A) = P(A&B)/P(A) = 0.20/0.50 = 0.4
A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.
from the given table
when x=0 , y=20
when x= 1 , y = 30
We use this information to find exponential growth equation
General form of exponential growth is

WE plug in the given values and find out value of a and b
when x=0 , y=20

20 = a
Now we find out b
when x= 1 , y = 30

divide both sides by 20

So exponential function becomes

Now we find the insect population at the end of week 11
We plug in 11 for x


Round the answer to nearest whole number
1730 is the insect population at the end of week 11
Answer:
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.
Sample proportion
<u><em>Step(ii)</em></u>
The 95% confidence interval estimate of the proportion of people who say that they voted


(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)
(0.6996 - 0.02838 , 0.6996 + 0.02838)
(0.67122 , 0.72798)
<u><em>Final answer</em></u>:-
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Answer:
THE CORRECT ANSWER IS D " THE THEORETICAL PROBABILITY OF PULLING A BLUE PEN BASED ON THE EXPECTED FREQUENCY WILL GET CLOSER TO 1/2 AS THE NUMBER OF TRIALS INCREASES. "
Are we solving for h?
V=πr²h+r²h
V=h(πr²+r²)
V/(πr²+r²) = h
