D. Because the interest is compounded more frequently, you will get more money. This is because it allows you to earn interest on previous interest more frequently.

Answer : D

The same amount of principal is invested in different accounts earning the same interest rate.

The account will not grow without interest

Lets assume , initial amount P= 100, rate of interest = 5%=>r= 0.05 and

number of years, t= 1

Calculate the simple interest

A = P + P*r*t = 100 + 100*.05*1= 105

In simple interest, $100 invested , amount earned = $105

Now we calculate earning interest compounded annually

A= P(1+\frac{r}{n})^{t*n}

Lets assume , initial amount P= 100, rate of interest = 5%=>r= 0.05 and

number of years, t= 1, for compounded annually n= 1

A= 100(1+\frac{0.05}{1})^{1*1}= 105

For interest compounded annually, $100 invested , amount earned = $105

Now we calculate earning interest compounded daily

A= P(1+\frac{r}{n})^{t*n}

Lets assume , initial amount P= 100, rate of interest = 5%=>r= 0.05 and

number of years, t= 1, for compounded annually n= 365

A= 100(1+\frac{0.05}{365})^{1*365}= 105.26

For interest compounded daily, $100 invested , amount earned = $105.26

So, An account compounded daily will have greatest accumulated value at the end of one year

Create a table and graph y=x+1 demos<br>​
DerKrebs [107]

Answer:

The table will be:

x          y=x+1

1            2

2           3

3           4

4           5

5           6

The graph is shown in figure attached.

Step-by-step explanation:

We need to create table and graph the expression: y=x+1

Table is made, such that we take value of x and find value of y

You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.

So our table will be:

x          y=x+1

1            2

2           3

3           4

4           5

5           6

Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.

The graph is shown in figure attached.

a poll shows that 64% of americans personally worry a great deal about federal spending and the budget deficit.
marysya [2.9K]

In the research, it should be noted that this is a Proportion, because worry or not worry is categorical

<h3>What is a proportion?</h3>

A population proportion is the percentage of the population that possesses a particular trait.

For illustration, suppose there are 1,000 people in the population and 237 of them have blue eyes. There are 237 blue eyed people out of every 1,000 people, or 237/1000.

Therefore, it should be noted that this is a Proportion, because worry or not worry is categorical.

According to the University of Nevada Center for Logistics Management, 6% of all mer-
Fudgin [204]

Answer:

a) The point estimate of the proportion of items returned for the population of

sales transactions at the Houston store = 12/80 = 0.15

b) The 95% confidence interval for the proportion of returns at the Houston store = [0.0718 < p < 0.2282].

c) Yes.

We set an hypothesis and construct a test statistics. The test statistics result gives us:

Z calculated  = 2.2545, and this gives us the p-value = 0.0121. We assumed 95% confident interval. Hence, the level of significance (α) = 5%. Conclusively, since the p-value ==> 0.0121 is less than (α) = 5%, the test is significant. Hence, the proportion of returns at the Houston store is significantly different from the returns  for the nation as a whole.

Step-by-step explanation:

a) Point estimate of the proportion = number of returned items/ total items sold = 12/80 = 0.15.

b) By formula of confident interval:

CI(95%) = p ± Z*\sqrt{\frac{p*(1-p)}{n} }  =  0.15 \pm 1.96 *\sqrt{\frac{0.15*(1-0.15)}{80} },

CI(95%) = [0.0718 < p < 0.2282]

c) The hypothesis:

H_{0}: The proportion of returns at the Houston store is not significantly different from the returns  for the nation as a whole.

H_{a}: The proportion of returns at the Houston store is significantly different from the returns  for the nation as a whole.

The test statistics:

Z = \frac{\hat{p} - p_{0}}{\sqrt{\frac{p*(1-p)}{n} }}, where p_{0} is the proportion of nation returns.

Z calculated  = 2.2545, and this gives us the p-value = 0.0121. We assumed 95% confident interval. Hence, the level of significance (α) = 5%. Conclusively, since the p-value ==> 0.0121 is less than (α) = 5%, the test is significant. Hence, the proportion of returns at the Houston store is significantly different from the returns  for the nation as a whole.
