Answer:  The answer is (B) making about the same amount in today's dollars.

Step-by-step explanation:  Given that our boss is impressed with our work and give us a 3% raise.

We are to select the correct statement if there is an inflation of 3%.

Since the raise of 3% and inflation rate of 3% occur simultaneously, so there will not be much change in the amount of money we are making in dollars.

Thus, (B) is the correct option.

Solve graphically the inequality \[ x ≥ 2 \]
Xelga [282]

1) Graph the corresponding equation \( x = 2 \); this will split the plane into two regions. One of the region represents the solution set.

2) Select a point situated in any of the two regions obtained and test the inequality. If the point selected is a solution, then all the region is the solution set. If the selected point is not a solution, then the other (second) region represents the solution set.

3) Test: In this example, let us for example select the point with coordinates (3 , 2) which is in the region to the right of the line x = 2. If you substitute x in the inequality \( x ≥ 2 \) by 3 it becomes \( 3 ≥ 2 \) which is a true statement and therefore (3 , 2) is a solution. Hence, we can conclude that the region to the right of the vertical line x = 2 is a solution set including the line itself which is shown as a solid line because of the inequality symbol \( ≥ \) contains the \( = \) symbol. The solution set is represented by the blue hash region in the graph below including the line x = 2.

The principal at Riverside High School would like to estimate the mean length of time each day that it takes all the buses to ar
Lilit [14]

Answer:

C) 11

Step-by-step explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

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".

\bar X represent the sample mean for the sample  

\mu population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

Since the Confidence is 0.90 or 90%, the value of \alpha=0.1 and \alpha/2 =0.05, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that z_{\alpha/2}=1.64

The margin of error is given by this formula:

ME=z_{\alpha/2}\frac{s}{\sqrt{n}}    

And on this case we have that ME =7 and we are interested in order to find the value of n, if we solve n from the last equation we got:

n=(\frac{z_{\alpha/2} s}{ME})^2  

And replacing the values that we got we have:

n=(\frac{1.64(14)}{7})^2 =10.758 \approx 11

HELP ME PLSSSSSS!!!!!!!!!!!!!!!
xxMikexx [17]

Answer:

<em>No.</em>

Step-by-step explanation:

<em>5c-6=4-3c</em>

<em>5c-6+6=4-3c+6 Add six to both sides</em>

<em>5c=-3c+10 Simplify</em>

<em>5c+3c=-3c+10+3c Add 3c to both sides</em>

<em>8c=10 Simplify</em>

<em>8c/8=10/8 Divide both sides by 8</em>

<em>c=5/4 <<< Simplify and you get that</em>

<em>So they (Student A) are/is not correct.</em>

Hope this helps, have a good day. c;
