The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.

<h3 /><h3>How to get the angle in radians?</h3>

Remember the relation:

180° = 3.14 radians.

Then:

60° = (60°/180°)*3.14 rad = 1.05 rad.

Now, for a circle of radius R, an arc defined by an angle θ has a length:

L = θ*R

Then the length of this arc is:

L = 1.05*1 unit = 1.05 units.

Can anyone help me pls I will mark brainlist !! :)))
Kay [80]

Answer:

14 inches

Step-by-step explanation:

The volume of a rectangular prism is V=l*w*h

Given the info in the problem, we have:

840=l*10*6

840=60l

14=l

The length of the prism is therefore 14 inches because volume is length*width*height and since we already have the volume, height, and width, we need to get the variable for length by itself.

Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the pop
Andreyy89

Answer:

The smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.

Step-by-step explanation:

The complete question is:

The mean salary of people living in a certain city is $37,500 with a standard deviation of $2,103. A sample of n people will be selected at random from those living in the city. Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income. Round your answer up to the next largest whole number.

Solution:

The (1 - <em>α</em>)% confidence interval for population mean is:

CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

The margin of error for this interval is:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

The critical value of <em>z</em> for 90% confidence level is:

<em>z</em> = 1.645

Compute the required sample size as follows:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

      n=[\frac{z_{\alpha/2}\cdot\sigma}{MOE}]^{2}\\\\=[\frac{1.645\times 2103}{500}]^{2}\\\\=47.8707620769\\\\\approx 48

Thus, the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.
