$1536 divided by $256 is $6 per bracelet.

The cost for a company to manufacture "x".... 
These statements tell you what X is. (The word cost refers to what the function will tell us. In other words C(x) = The Cost for the Company)) 

So as we keep going the problem goes onto: 
.... bracelets
So the number of bracelets is X. 

The function is: C(x) 

And how functions work are quite simple. You plug in a number (x) and get out a number (y).

So, C(256) = 1536

So, they made 256 bracelets at a cost of 1536 dollars. 

This is no different than if I said the function was: 
C(x) = 6x
And then asked, what would the function equal when x = 256. It's the same thing, so don't let it trip you up! 

Answer 1: 1536$
Answer 2: 256

Vlad1618 [11]

Answer:

Confidence =1-\alpha=1-0.01=0.99

And then the confidence level would be given by 99%

Step-by-step explanation:

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Assuming the X follows a normal distribution

X \sim N(\mu, \sigma)

The distribution for the sample mean is given by:

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

\bar x =512 represent the sample mean

\sigma=100 represent the population standard deviation

n= 100 sample size selected.

The confidence interval is given by this formula:

\bar X \pm z_{\alpha/2} \frac{\sigma}{\sqrt{n}}   (1)

The marginof error for this case is given by Me=25.76. And we know that the formula for the margin of error is given by:

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

25.76=z_{\alpha/2} \frac{100}{\sqrt{100}}

And we can find the critical value z_{\alpha/2} like this:

z_{\alpha/2}=\frac{25.76(\sqrt{100})}{100}=2.576

And we know that on the right tail of the z score =2.576 we have \alpha/2 of the total area. We can find the area on the right of the z score using this excel code:

"=1-NORM.DIST(2.576,0,1,TRUE)" or using a table of the normal standard distribution, and we got 0.004998=\alpha/2, so then \alpha=0.00498*2=0.009995 \approx 0.01, and then we can find the confidence like this:

Confidence =1-\alpha=1-0.01=0.99

And then the confidence level would be given by 99%

There are 6 diagonals that can be drawn from one vertex of an octagon, true or false.

It's False; an octagon has 8 vertices. When you remove the starting vertex and the two adjacent vertices we're left with 5 possible diagonals

Edge length = 63 feet

Volume = (length) x (width) x (height)

Volume = (63 ft) x (63 ft) x (63 ft) = (63 ft)³ = 250,047 ft³ .
=====================================

1 yard = 3 ft
63 ft = 21 yards

Volume of the cube = (21 yd) x (21 yd) x (21 yd) = (21 yd)³ = 9,261 yd³
======================================

A slightly different way:

1 yard = 3 ft
1 yard³ = (3 ft)³ = 27 ft³

Volume of the cube = (250,047 ft³) x (1 yd³/27 ft³) = 250,047/27 = 9,261 yd³
