This is a linear polynomials(or first degree polynomials). It is a form of y=ax+b.The line passes through (4, 5) and (2, 2), so we can build a dualistic equation:    ｛5=4k + b
   ｛2=2k + b
solve this equation, we can know that k=1.5 and b=-1, then the function is y=1.5x - 1, D is correct.
If y=1.5x - 1, then y-2=1.5x-1-2=1.5x-3=1.5(x-2), so A is correct, too.
y-4=1.5x-1-4=1.5x-5, so B is incorrect.
y-5=1.5x-1-5=1.5x-6=1.5(x-4), so C is correct.    Now we can know the answer: the correct options are A,C and D    Sorry my English expression is not very good, but hope it can help you:)

Add all cups of sugar, which would be 20. Divide it by 5 (the number of students in the class). 20/5 = 4.

Answer:

$654.16-2.02\frac{165.23}{\sqrt{42}}=602.66$

$654.16+2.02\frac{165.23}{\sqrt{42}}=705.66$

So on this case the 95% confidence interval would be given by (602.66;705.66)

Step-by-step explanation:

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".

$\bar X=654.16$ represent the sample mean

$\mu$ population mean (variable of interest)

s=165.23 represent the sample standard deviation

n=42 represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=42-1=41$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.025,41)".And we see that $t_{\alpha/2}=2.02$

Now we have everything in order to replace into formula (1):

$654.16-2.02\frac{165.23}{\sqrt{42}}=602.66$

$654.16+2.02\frac{165.23}{\sqrt{42}}=705.66$

So on this case the 95% confidence interval would be given by (602.66;705.66)

PLS HELPP QUICK QUESTION AND OPTIONS ARE BELOW IN ATTACHED FILE....

podryga [215]

Altogether there are 14 flavours of oatmeal.
The number of grams of fiber (per serving) is shown in the list/table.

What you're expected to do is to count the number of flavours that has the given number of grams of fibre (0-1, 2-3,...) and drag the appropriate tile to the appropriate location in the graph.

For example, for 0-1 grams of fibre. I see there is are 2- "1", and no zeroes. So there is only one single flavour that has 0-1 gram of fibre in a serving. You will need to drag the tile marked "2" in the first position (0-1).

For 2-3 grams, I see 3 "2" and 3 "3" for a total of six flavours. So you would drag the tile marked "6" to the second position in the graph (2-3).

Similarly, for 4-5 grams, I see 4-"4" and 1-"5", so again you drag the tile marked "5" to the third position on the graph.

Do the same for 6-7 grams, I see only 1-"6", so drag the tile marked "1" to the fourth position, then you're done!

Check: 2+6+5+1=14 ✔
