Step-by-step explanation:

Given

I. 0.1 II. 0.009 III. 0.09 IV. 1

Required

Write in descending order

In descending order means, from greatest to least.

From the given list of numbers,

The greatest is 1 (IV)

Followed by 0.1 (I)

Followed by 0.09 (III)

Then, the least is 0.009 (II)

So, the order is: IV, I, III and II

This table shows some values of an exponential function. x у 01.25 1 2.50 25 3 10 What is the function?

Helen [10]

Answer:

$y= 1.25(2)^{x}$

Step-by-step explanation:

$y= 1.25(2)^{x}$

For x=0

$y= 1.25(2)^{0} = 1.25$

For x=1

$y= 1.25(2)^{1} = 1.25(2)=2.5$

For x=2

$y= 1.25(2)^{2} = 1.25(4)=5$

For x=3

$y= 1.25(2)^{3} = 1.25(8)=10$

A 2003 survey showed that 14 out of 250 Americans surveyed had suffered some kind of identity theft in the past 12 months. What

ivann1987 [24]

Answer:

The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

A 2003 survey showed that 14 out of 250 Americans surveyed had suffered some kind of identity theft in the past 12 months.

This means that $n = 250, \pi = \frac{14}{250} = 0.056$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a p-value of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.056 - 1.96\sqrt{\frac{0.056*0.944}{250}} = 0.0275$

The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.

the area of rectangular park is 3/5 square mile, the length of the park is 7/8 mile,what is the width of the park

Luba_88 [7]

Area=LengthxWidth so 3/5=7/8xWidth. To get width by itself you must divide both sides by 7/8. When dividing fractions you can flip the fraction and multiply so multiply (3/5)(8/7). To do this just multiply the numerators and denominators to get 24/35 so width = 24/35
