Answer:

The winner received 12,800 votes and the loser received 12,400.

Step-by-step explanation:

Divided the votes in half, then took 100 votes from the winner, defined W, and added 100 to the loser, defined L to give the Loser a lead of 200. Then switch 300 votes from the losers number to the winner. You'll end up with 12,800 and 12,400 and you can check by switching 300 voters from winner (12,800) to loser (12,400) to make the loser win by 200 votes. 12,800 and 12,400 also add up to 25,200.

The future worth of a certain item or money deposited at a certain percentage is obtained by the equation,

F = P x (1 + i)^n

F is the future worth, P is present worth, i is the percentage, and n is the number of years.

n = 2013 - 1938
n = 75

Substituting the known values,

300,000 = 100 x (1 + i)^75

The value of i from the equation is 0.1126.

The answer to this item is 11.26%.

Answer:

Null Hypothesis: p = 0.65.

Step-by-step explanation:

The null hypothesis is the expected population population, from an assumption deriving for example, from a previous experiment.

According to a researcher who was quoted in a New York Times article in March, 2011, 65% of U.S. community college students must take at least one remedial course in English

This means that the expected value of the population proportion is $p = 0.65$ , which is the null hypothesis.

Null Hypothesis: p = 0.65.

givi [52]

The options given don't correspond to the values in the question. The options are from another question where mean is 5.3 and the probability being looked for is for exactly 3 occurrences and 5 occurrences

Answer:

A) 0.6511

B) Poisson distribution

Step-by-step explanation:

We are given;

Mean: μ = 5.4 minutes

Now, we want to find the probability that there are more than 5 occurrences in ten minutes.

This will be written as;

P(x > 5) = 1 - P(x < 5)

P(x < 5) = P(x = 4) + P(x = 3) + P(x = 2) + P(x = 1) + P(x = 0)

We will use Poisson distribution for this. The formula is;

P(x) = [(e^(-μ)) × μ^(x)]/x!

P(0) = [(e^(-5.4)) × 5.4^(0)]/0! = 0.004517

P(1) = [(e^(-5.4)) × 5.4^(1)]/1! = 0.02439

P(2) = [(e^(-5.4)) × 5.4^(2)]/2! = 0.06585

P(3) = [(e^(-5.4)) × 5.4^(3)]/3! = 0.11853

P(4) = [(e^(-5.4)) × 5.4^(4)]/4! = 0.16

Thus;

P(x < 5) = 0.16 + 0.11853 + 0.06585 + 0.004517 = 0.3489

Thus;

P(x > 5) = 1 - P(x < 5) = 1 - 0.3489 = 0.6511

B) like seen from solution A above, we used Poisson distribution formula.

Thus, random variable x satisfies Poisson distribution

Answer:

c tomato 2.5

pepper = 3.5

Step-by-step explanation:

Let t= the price of tomato plants

p =the price of pepper plants

3t+ 4p = 21.50

5t+ 2p = 19.50

Multiply the second equation by -2

-10t -4p =-39

Add this to the first equation to eliminate p

-10t -4p =-39

3t+ 4p = 21.50

---------------------

-7t = -17.5

Divide by -7

t = 2.5

Now find p

5t+ 2p = 19.50

5( 2.5) + 2p = 19.50

12.5+2p = 19.50

Subtract 12.5 from each side

2p =7

p =3.5

We want the price of 1 tomato and 1 p

3.5+2.5
