Answer:

Option D:The statement does not make sense. A sample is a subset of the population and cannot be larger than the population.

Step-by-step explanation:

The statement does not make sense. A sample is a subset of the population and cannot be larger than the population.

We measure characteristics of a sample to infere properties of the population. In real cases, the samples are much smaller than the population.

The sample size is calculated in order to achieve the desired level of confidence in the estimation. This confidence usually increases by the root of the sample size.

The members of the Student Activity Council on your campus are meeting to select three speakers for a​ month-long event celebrat
Komok [63]

The number of different ways that three speakers can be​ selected is 10 ways

Given the names of choice to be Ben, Will, Stewart, Hilary, and Kate. This means that we have a total of 5 name choices.

If the members of students activities are to select three speakers among these people, the number of ways this can be done is by using the combination rule as shown;

nCr=\frac{n!}{(n-r)!r!}

From the question, n = 5 and r = 3. On substituting

5C3=\frac{5!}{(5-3)!3!}\\5C3=\frac{5!}{2!3!}\\5C3=\frac{5 \times 4 \times 3!}{2 \times 3!} \\5C3=\frac{20}{2}\\5C3 = 10 ways

Hence the number of different ways that three speakers can be​ selected is 10 ways.

What is the value of k in y = kx, if y = 12 when x = 24?
Brrunno [24]

Answer:

k = 0.5

Step-by-step explanation:

Substitue y = 12, x = 24 into y = kx.

12 = k × 24

24k = 12

k = 12 ÷ 24

k = 0.5 (final answer)

Suppose you invested $10,000 part at 6% annual interest and the rest at 9% annual interest. If you received $684 in interest aft
victus00 [196]
Assuming simple interest (i.e. no compounding within first year), then
At 6%, interest = 10000*0.06=$600
At 9% interest = 10000*0.09 = $900

Two ways to find the ratio
method A. let x=proportion at 6%
then
600x+900(1-x)=684
Expand and solve
300x=900-684=216
x=216/300=0.72 or 72%
So 10000*0.72=7200 were invested at 6%
10000-7200=2800 were invested at 9%

method B: by proportions
Ratio of investments at 6% and 9%
= 900-684 : 684-600
=216 : 84
= 18 : 7
Amount invested at 6% = 18/(18+7) * 10000 = 0.72*10000 = 7200
Amount invested at 8% = 7/(18+7)*10000=0.28*10000=2800
