Using the interpretation of the confidence interval, it is found that the correct option is:

e) No, the confidence interval contains 0, so 0 is a plausible value for the true mean increase in number of miles driven on 25 gallons. An increase of 0 would indicate the gas mileage has not increased.

It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.

In this question, the 99% confidence interval for the increase is of (-3.95, 64.35). It contains 0 and negative values, hence those are plausible values, and this is not enough evidence that the mean has increased, hence option e is correct.

The remainder of the expression x/(x + 1) is a negative one. Then the correct option is D.

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expression is given below.

[tex]\rm \rightarrow \dfrac{x}{x+1}[/tex]

Add and subtract 1 in the numerator, then we have

[tex]\rm \rightarrow \dfrac{x+1-1}{x+1}\\\rm \rightarrow 1 -\dfrac{1}{x+1}[/tex]

Then the remainder will be a negative one.

It looks weird but trust me

Ok so first you have to mutiply 2*2 whitch is 4

(4^2 * -1^3)^2

now what is the 1 with the exponet of 3? It will stay at -1

(4^2 * -1) ^2

what is 4^2? it is the same a 4*4

Answer: Angle sum

Step-by-step explanation:

well, the original price was 500 bucks, but went down to 325, namely 500 - 325 = 175, so she'll be saving 175 bucks.

if we take 500 to be the 100%, what is 175 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 500 & 100\\ 175& x \end{array} \implies \cfrac{500}{175}=\cfrac{100}{x}\implies \cfrac{20}{7}=\cfrac{100}{x} \\\\\\ 20x=700\implies x=\cfrac{700}{20}\implies x=35[/tex]

The work for the possible next step which Sharina need to do is to distribute the 3 to each term in the parentheses by multiplying.

Simplified form of a term is the simplest way of expression the term, by applying the required operations of mathematics. To simplify the equation, the BODMOS method is used.

Sharina simplified the expression 3(2x – 6 – x 1)2 – 2 4x.

The table of Sharina's work

In this table, rows 3 and 4 are blank. The next term to be filled in the 3rd row. The equation solved by her in the second row is,

[tex]3(x^2 - 10x +25) -2 +4x.[/tex]

According to the rule of BODMAS, she first has to open the bracket by distribute the 3 to each term in the parentheses by multiplying.

Hence, the work for the possible next step which Sharina need to do is to distribute the 3 to each term in the parentheses by multiplying.

The coordinates of the final point after the two reflections is (-7, -4)

For a point (x, y), a reflection across the x-axis gives the point (x, -y), while for a point (x, y) a reflection across the y-axis gives (-x, y).

In this case, we have the point (7, 4), first we reflect across the x-axis, so we get the point (-7, 4).

Now we reflect across the y-axis, so the sign of the y-component changes, and we get (-7, -4)

So the coordinates of the final point after the two reflections is (-7, -4).

We have this stem-and-leaf plot

[tex]\begin{array}{r|l}\text{stem} & \text{leaf}\\\cline{1-2}5 \ & \ 0 \ 4\\6 \ & \ 5 \ 7 \ 8\\7 \ & \ 5 \ 8\\8 \ & \ 2 \ 4 \ 5 \ 5 \ 5 \ 6 \ 7 \ 8 \ 9\\9 \ & \ 0 \ 0 \ 0 \ 0 \ 4 \ 6 \ 7 \ 9\\\end{array}[/tex]

where something like [tex]5 \big| 0[/tex] represents the number 50.

The most frequent leaf is "0" in the very bottom row. It shows up four times, which is the most of any of the other leaf.

This leaf ties to the stem of 9.

stem = 9 & leaf = 0 leads to the data value 90.

Therefore, the mode is 90

The process is an isochoric process. Then the tire pressure change in response to the change in temperature is 2.65 atm.

It is a branch of science that deals with heat and work transfer.

An automobile tire at 30.0°C has a pressure of 3.00 atm.

The temperature decreases to -5.00°C.

Assume that there is no volume change in the tire.

Then for the constant volume process, we have

[tex]\dfrac{P_1}{P_2} = \dfrac{T_1}{T_2}\\\\\dfrac{3}{P_2} = \dfrac{303}{268}\\\\P_2 \ = 3\times \dfrac{268}{303}\\\\P_2 \ = 2.65[/tex]

what is an exterior angel theorem

Answer:

C.  The x-coordinate of the vertex must be 6

Step-by-step explanation:

The parabola intercepts the x-axis when y = 0.

Therefore, if the quadratic equation has the points (2, 0) and (10, 0) then the x-intercepts or "zeros" are x = 2 and x = 10.

The x-coordinate of the vertex is the midpoint of the zeros.

[tex]\sf \implies midpoint=\dfrac{2+10}{2}=6[/tex]

Therefore, the solution is option C.

Additional Information

The leading coefficient of a quadratic tells us if the parabola opens upwards or downwards:

We have not been given this information and so therefore cannot determine the way in which it opens.

As we do not know the way in which way the parabola opens, we cannot determine if the parabola will have a negative or positive y-intercept.

We have not been given the full quadratic equation, and so we cannot determine if the parabola is wider (or narrower) than the parent function.

Find the quadratic equation

[tex]\\ \rm\Rrightarrow (x-2)(x-10)=y[/tex]

[tex]\\ \rm\Rrightarrow y=x(x-10)-2(x-10)[/tex]

[tex]\\ \rm\Rrightarrow y=x^2-10x-2x+20[/tex]

[tex]\\ \rm\Rrightarrow y=x^2-12x+20[/tex]

Convert to vertex form of parabola

[tex]\\ \rm\Rrightarrow y=x^2-2(6x)+20+16-16[/tex]

[tex]\\ \rm\Rrightarrow y=x^2-2(6x)+36-16[/tex]

[tex]\\ \rm\Rrightarrow y=(x-6)^2-16[/tex]

A sample median of 1,005 visitors would be most likely to occur for the sample size given by: Option A: 20

As the value of n (the sample size) grows larger, the sampling distribution tends to being normal. For an approximate normal distribution, its mean, median, and mode all are approx coincident. And as the sample size increases, the sample mean tends to being the population mean as per the weak law of large numbers. For n > 30, we can approximate it using normal distribution usually.

We're given that:

So, as we know, as the sample size increases, the sample mean and sample median and sample mode, all will tend to the population mean, median and mode (assuming population is large enough that they're all same).

Thus, the smaller the sample size, the more likely it is for holding 1005 as sample median instead of approx 893.

So, size 20 is most likely to have that median as it is the smallest sample size given.

Thus, a sample median of 1,005 visitors would be most likely to occur for the sample size given by: Option A: 20

You can prove triangles’ congruence with things called axioms (or postulates). For triangles, there are four:

(S means Side, A means Angle)

SAS

SSS

ASA

AAS

If you go round a triangle, in order (so aside, then the next angle, next side, etc.), and find that everything from one of these postulates is equal, you have two congruent triangles.

(These triangles’ sides and angles, which are marked on the image, are equal to the other’s)

This diagram shows the SAS axiom, as the equal parts of the triangle go in order of a side (Y to Z), an angle (Y to Z to X), and another side (Z to X).

The greatest possible probability in any experiment is 1 as the least possible probability in any experiment is 0.

Probability simply means the likelihood of the occurence of an event.

In this case, the greatest possible probability in any experiment is 1 as the least possible probability in any experiment is 0.

Also, a probability around 0.5 means that the event is neither likely nor unlikely.
