bazaltina [42]

Answer:

sorry i only know the answer of c

it's 8.2 gallons

Step-by-step explanation:

12 gallons = 420 miles

12 gallons = 420 miles? gallons =287 miles

420 miles ÷ 12 gallons = 35miles/gallon

420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons

Suppose you take $5800 and invest it with an 8% interest rate for 16 years compounded continuously, how much money will you have

VladimirAG [237]

Answer:

$20,860.51

Step-by-step explanation:

The multiplier of the investment is e^(rt), where r is the interest rate and t is the time period. In this case, the balance will be ...

A = 5800·e^(0.08·16) = 5800·e^1.28 ≈ 5800·3.5966397 = 20,860.51

You will have about $20,860.51.

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hi

kenny6666 [7]

Using the z-distribution, we have that:

The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.

The margin of error is of 0.8 in.

The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the sum of all observations divided by the number of observations. Hence:

$\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1$

The margin of error of a z-confidence interval is given by:

$M = z\frac{\sigma}{\sqrt{n}}$

In which:

z is the critical value.
$\sigma$ is the population standard deviation.
n is the sample size.

We have to find the critical value, which is z with a p-value of $\frac{1 + \alpha}{2}$ , in which $\alpha$ is the confidence level.

In this problem, $\alpha = 0.99$ , thus, z with a p-value of $\frac{1 + 0.99}{2} = 0.995$ , which means that it is z = 2.575.

Then, the margin of error is:

$M = z\frac{\sigma}{\sqrt{n}}$

$M = 2.575\frac{1.2}{\sqrt{15}}$

$M = 0.8$

The margin of error is of 0.8 in.

The interval is:

$\overline{x} \pm M$

$\overline{x} - M = 44.1 - 0.8 = 43.3$

$\overline{x} + M = 44.1 + 0.8 = 44.9$

The interpretation is:

Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

How can you tell whether a positive or negative association exists

stira [4]

Answer:

You can tell whether or not something is positive or negative by looking at the specific number for example if you look at this number -5 you know its a negative number because it has a - sign.Although when its positive it does not have any kind of format of signs according to my calculations.

Hope this helps!

Please give me 5 stars if it did i would very much appreciate it !!
