A $60,000 piece of machinery depreciates in value at a rate of 11% per year. About what will its value be in 5 years?

kicyunya [14]

Answer:

$27000

Step-by-step explanation:

11% of 60000 is 3300 per year. You need the value for five years so multiply 3300 * 5 to get 33000. 33000 is the total depreciation of the five years. Then subtract 33000 from 60000 to get 27000.

The equatorial radius of the planet Jupiter is measured 40 times by a process that is practically free of bias. These measuremen

Nina [5.8K]

Answer:

The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.

Step-by-step explanation:

Sample size of 30 or larger, so we can use the normal distribution to find the confidence interval.

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.93}{2} = 0.035$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.035 = 0.965$ , so $z = 1.81$

Now, find M as such

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

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.81*\frac{28}{\sqrt{40}} = 8$

The lower end of the interval is the sample mean subtracted by M. So it is 71492 - 8 = 71484 km.

The upper end of the interval is the sample mean added to M. So it is 71492 + 8 = 71500 km.

The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.

What is the y-intercept of the equation of the line that is perpendicular to the line y = x + 10 and passes through the point (1

Svetlanka [38]

You need to substitute the x and y values into the original and subtract 15 from each side to get b. You should get a b value of -20

Which equation is equivalent to 4s=t+ 2?S= 1-2S=4/t+2S =t+2/4 S=t+6

Marina CMI [18]

SOLUTION:

We are to make S the subject of the formula;

$\begin{gathered} 4S\text{ = t + 2} \\ \text{Divide both sides by 4} \\ \frac{4S}{4}\text{ = }\frac{t\text{ + 2}}{4} \\ S\text{ = }\frac{t\text{ + 2}}{4} \\ \\ \end{gathered}$

The correct option is the third one.
