Lindsey purchased a random sample of 25 tomatoes at the farmers market. The 95% confidence interval

In a manufacturing process, a machine produces bolts that have an average length of 5 inches with a variance of .08. If we rando

xz_007 [3.2K]

Answer:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And replacing:

$\mu_{\bar X}= 5$

And the deviation:

$\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126$

And the distribution is given:

$\bar X \sim N(\mu= 0.08, \sigma= 0.126)$

Step-by-step explanation:

For this case we have the following info given :

$\mu= 5. \sigma^2 =0.08$

And the deviation would be $\sigma = \sqrt{0.08}= 0.283$

For this case we select a sample size of n = 5 and the distirbution for the sample mean would be:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And replacing:

$\mu_{\bar X}= 5$

And the deviation:

$\sigma_{\bar X}= \frac{0.283}{\sqrt{5}}= 0.126$

And the distribution is given:

$\bar X \sim N(\mu= 0.08, \sigma= 0.126)$

I need help with this !! chart

Burka [1]

Answer:

Make coordinates with this table.

Step-by-step explanation:

What I think from these tables is that you can make coordinates with these points. Here are the instructions for you to follow-

See the "y" and "x". These are the axis. So make coordinates with these. Ex- (0,3), (1,5) and so on
Plot these coordinates in a graph paper.
After plotting them, you might find the shape it made.

I hope it helps you.

You have just signed up for a broadband home internet service that uses coaxial cable. which connector type will you most likely

vampirchik [111]

F type connector

The F-connector is a coaxial RF connector commonly used for "wireless" terrestrial television, cable television, and common for satellite television and cable modems, usually with RG-6/U cable or with RG -59 / U.

F connector is also known as threaded connector. There are two main types: 7mm (6.8mm) is the most common and used in coaxial cable, and 5mm connector is used in thin coaxial cable commonly used in satellite system.

The F-connector is an accessory that connects a coaxial cable to an electronic device or wall outlet.

Type F connectors are highly mechanical and electrically stable coaxial screw connectors for cable television (CATV), set-top boxes, cable modems and satellite television applications up to 4 GHz

Joe is looking for a new laptop case. His computer is 18 x 13.5 inches. What is the perimeter and area of the laptop case?

sineoko [7]

Answer:

Perimeter =63 inches

Area = 243in²

Step-by-step explanation:

Given data

Length of computer = 18in

Width of computer = 13.5in

From the given data the computer has a rectangular shape

Perimeter of the computer = L+L+W+W= 2L+2W

Perimeter = 2(18)+ 2(13.5)

Perimeter = 36+27=63 inches

Area of rectangular shape = L*W

Area = 18 x 13.5= 243in²
