eric can spend a maximum of $270 on office supplies. Each rem of paper costs $6. Each ink catridge costs $18. Which of the follo

Vladimir [108]

If we say A = ream of paper and B = cost of ink than we can set-up an expression to calculate when A is equal to a number what the number of B will be. Maximim of 270$ so anything we buy must be equal to this. Ream of paper cost 6$ each so 6A represents the number of reams bought since we said A is number of reams of paper. Ink Cartridges are 18$ each so 18B would represent this based on B = to cost of ink. Now setting up our equation 6A + 18B = 270 When A = 1 B = 14.67 Ink Cartridges When A = 1 Ream ofpaper

If it is assumed that the heights of men are normally distributed with a standard deviation of 2.5 inches, how large a sample sh

Volgvan

Answer:

30 men

Step-by-step explanation:

In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:

$0.90 < Z\frac{s}{\sqrt{n}}$

Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:

$0.90 > 1.960\frac{2.5}{\sqrt{n}}\\n >(\frac{1.960*2.5}{0.9})^2\\n>29.64$

Rounding up to the nearest whole number, the sample size should be at least 30 men.

What is seven less than three times a number.

Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.

Which of these statements best describes the relation shown in Item 1?

Misha Larkins [42]

Answer:

It is a many-to-one relation

Step-by-step explanation:

Given

See attachment for relation

Required

What type of function is it?

The relation can be represented as:

$\left[\begin{array}{c}x\\ \\-5\\-2\\1\\5\end{array}\right]$ $\left[\begin{array}{c}y\\ \\10\\11\\4\\10\end{array}\right]$

Where

$x = domain$ and $y = range$

Notice that the range has an occurrence of 10 (twice)

i.e.

$(x_1,y_1) = (-5,10)$ and $(x_2,y_2) = (5,10)$

In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
