Answer:

12

Step-by-step explanation:

3*4 = 12

12/6 = whole number

6/4 is not a whole number

12 is the lowest it could be.

Also those kids have issues.

A marketing consultant observed 50 consecutive shoppers at a supermarket. One variable of interest was how much each shopper spe
Diano4ka-milaya [45]

Answer:

a. \\ \mu = USD\;51.34; b. The 95% interval is USD [45.82, 56.86].

Step-by-step explanation:

The mean amount a customer spends at the grocery store

The mean is the sum of all of the data divided by the number of observations for this case, that is, n = 50.

The sum of all of the data is: 5.24+11.97+13.59+15.52+15.69+19.96+20.54+22.59+27.25+27.29+28.25+30.00+31.63+33.01+37.21+40.36+40.90+42.83+45.66+46.67+47.49+49.32+50.12+51.71+52.2 1+53.57+56.16+56.36+56.88+58.65+59.42+60.20+60.48+62.23+62.50+67.95+70.45+73.08+74.15+74.48+74.78+75.75+76.27+76.47+78.92+84.09+84.91+85.06+88.45+88.91 = 2567.17.

The mean \\ \mu is

\\ \mu = \frac{2567.17}{50}

\\ \mu = \frac{2567.17}{50} = 51.34

Then, <em>the mean amount a customer spends at the grocery store is</em> USD 51.34.

The 95% confidence interval for the mean amount spent

For the 95% confidence interval for the mean, we have the value for the <em>mean = </em>51.34, as we have just found, the value for the<em> standard deviation</em> is already given as USD 20.00. There are 50 observations, so n = 50.

Moreover, for a 95% confidence, the value for the corresponding z-score is z = 1.96 (this is the confidence coefficient). Then, the formula for finding the "limits" values for the confidence interval is as follows:

For the upper limit  

\\ \overline{X} + 1.96*\frac{\sigma}{\sqrt{n}}

\\ 51.34 + 1.96*\frac{20}{\sqrt{50}}

\\ 51.34 + 5.52

\\ 56.86

For the lower limit

\\ \overline{X} - 1.96*\frac{\sigma}{\sqrt{n}}

\\ 51.34 - 1.96*\frac{20}{\sqrt{50}}

\\ 51.34 - 5.52

\\ 45.82

Thus

The 95% confidence is USD [45.82, 56.86].

Mathematically

\\ P(45.82 \leq \mu \leq 56.86) = 0.95

There is a probability of 0.95 that the values are between [45.82, 56.86], both inclusive.

We have to remember here that we are dealing with a sample. This sample has a standard deviation, called standard error of the sample, and is \\ \frac{20}{\sqrt{50}} \approx 2.83.

So, the population mean is, with a 95% confidence, between the values [45.82, 56.86], both inclusive.

We can see the graph below that represents the former.

Can anyone help me with this Function
mr Goodwill [35]

Answer:

\Large \boxed{\sf \ \ 6x^2-2x-6 \ \ }

Step-by-step explanation:

Hello, please consider the following.

(f-g)(x)=f(x)-g(x)=6x^2-4-(2x+2)\\\\=6x^2-4-2x-2=\large \boxed{6x^2-2x-6}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Help me!<br> what is the domain or range?
Lapatulllka [165]
Domain is [-10,∞) 
2 is included , only at x=2 new function begins
Range is the values of y , so range  is [-7]∪[-4,6
I think, it should be  like this.

Which of the following functions is graphed below?
denis-greek [22]

The option that is the functions is graphed below is known as option A = Y= (x+4) -2.

<h3>What is the function about?</h3>

The function graphed above is Y=|x+4|-2 because  when you solve for the graphs,  the number in the x-axis is always changed or turned to  the other side and there one can see that it would be -4 would be +4, and +4 and also -4.

Note that

Y = (x+4) -2.

x = (0 + 4) - 2

x = 4-2

x =2

Therefore, plug x into the equation.

Y = (x+4) -2.

= ( 2 + 4) - 2

= (6) -2

= 4

Therefore, The option that is the functions is graphed below is known as option A = Y= (x+4) -2.
