Answer:

(5,4), (2, -7), (4, -3)

Step-by-step explanation:

The first option is (-2,5), (7,2), (5, 4).

The domain for this pair of ordered pairs is {-2,5,7}

The second set is (5,4), (2, -7), (4, -3)

The domain is {2,4,5}

The third set is (2, -7), (4, -3), (-2,5), (5, 4)

The domain is {-2,2,4,5}

The fourth set is (4,-3), (-2,5), (5,4), (7,2)

The domain is {-2,4,5,7}

Therefore the correct choice is the second option

In how many ways can we choose a 12 member jury from 30 possible people?

Pachacha [2.7K]

This is a problem dealing with permutations and combinations.
Order does not matter in this problem.
Since order doesn't matter, it is a combination.
Repetition matters, since you can't have the same person count as two people.

There are twelve slots.

_ _ _ _ _ _ _ _ _ _ _ _

Each slot needs to be multiplied by the next.

_*_*_*_*_*_*_*_*_*_*_*_

Now we have to fill in the slots.
Each slot will be filled with a number one less than the one before it. It has to be one less, since repetition matters.
The numbers will be decreasing from 30, since there are 30 possible people.

30 * 29 * 28 * 27 * 26 * 25 * 24 * 23 * 22 * 21 * 20 * 19

Multiply these numbers together and you get your answer.

Aleksandra started studying how the number of branches in her tree grows over time. Every 1.5 years, the number of branches incr

vova2212 [387]

Answer:

N = 52 * (9/7)^(t/1.5)

Step-by-step explanation:

This problem can be modelated as an exponencial problem, using the formula:

N = Po * (1+r)^(t/1.5)

Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.

In our case, we have that N is the final number of branches after t years, Po = 52 branches, r = 2/7 and t is the number of years since the beginning (in the formula we divide by 1.5 because the rate is defined for 1.5 years)

Then, we have that:

N = 52 * (1 + 2/7)^(t/1.5)

N = 52 * (9/7)^(t/1.5)

Determine the point estimate of the population mean for the confidence interval of (15, 32). Enter up to 1 decimal place. Point

netineya [11]

Answer:

The point estimate of the population mean for the confidence interval of (15,32) is 23.5

Step-by-step explanation:

We are given the following information in the question:

Confidence interval for population mean is (15, 32).

We have to find the point estimate for population mean.

Formula:

$\mu = \displaystyle\frac{\mu_1+\mu_2}{2} = \frac{15+32}{2} = 23.5$

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5
