The total cost for driving 150 miles would be $75.50.

The probability that the claim of James is correct is 1%.

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is its standard error. The standard error of the mean is the term used when the statistic is the sample mean.

In order to know if the claim of James is correct or not, firstly we need to determine the standard error. The standard error is the ratio of the standard deviation and the square root of the sample. Therefore, the standard error can be written as,

[tex]\rm Standard\ Error, SE =\dfrac{\sigma}{\sqrt n} = \dfrac{0.4}{\sqrt5} =0.178[/tex]

Thus, the standard error is 0.178.

Further, The z-score is defined as the distance from the sample to the population mean in units of standard error. Therefore, the z-score can be written as,

[tex]z = \dfrac{X-\mu}{SE}=\dfrac{(3- 2.5)}{0.178} = 2.81[/tex]

Using the Z-table in order to know the probability of the claim of James is correct or not, therefore, at this z-score, the probability is 0.9974≈1.00%.

Hence, the probability that the claim of James is correct is 1%.

The z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is  z = 2.14;  s = 4;  n = 81.

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

The formula of the margin of error is given by the formula,

[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]

A.)  z = 2.14;  s = 4;  n = 9

The margin of error is,

[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]MOE = 2.14\times \dfrac{4}{\sqrt{9}}\\\\\\MOE =2.85[/tex]

B.) z = 2.14;  s = 4;  n = 81

The margin of error is,

[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]MOE = 2.14\times \dfrac{4}{\sqrt{81}}\\\\\\MOE =0.9511[/tex]

C.)  z = 2.14;  s = 16;  n = 9

The margin of error is,

[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]MOE = 2.14\times \dfrac{16}{\sqrt{9}}\\\\\\MOE =11.413[/tex]

D.)  z = 2.14;  s = 16;  n = 81

The margin of error is,

[tex]MOE = Z_{\gamma}\times \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]MOE = 2.14\times \dfrac{16}{\sqrt{81}}\\\\\\MOE =3.80[/tex]

hence, the z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is  z = 2.14;  s = 4;  n = 81.

Answer:

  11. s = 14

  12. k = 24

Step-by-step explanation:

There are two "special" right triangles that show up in trig and geometry problems.

The isosceles right triangle has angles of 45°-45°-90°, and side length ratios 1 : 1 : √2.

The half-equilateral triangle has angles of 30°-60°-90°, and side length ratios 1 : √3 : 2.

You will do yourself a favor if you remember and learn to recognize these triangles.

__

The hypotenuse of the isosceles right triangle is 14√2. This tells you the basic ratio has been multiplied by 14. The side length is ...

  s = 14

__

The half-equilateral triangle has middle-length side 12√3. This means the basic ratio has been multiplied by 12. The triangle short side is 12, and the long side is twice that:

  k = 24

Given a defined function

f(x), we can evaluate the function at any constant by replacing every x

with that constant.So if f(x)=3x+5x, then f(a+2)=3(a+2)\+5a+2

The given rectangles 2 and 3 are similar.

Similar figures mean when two figures are of the same shape but are of different sizes. In other words, two figures are called similar when they both have a lot of the same properties but still may not be identical.

From the rectangle 2 and 3,

18/40 = 36/80

9/20 = 9/20

So, figure 2 and 3 are similar

Answer: Loss of 925

==============================================

Work Shown:

Total cost = 8250+175 = 8425

Total revenue = 7500

Profit = revenue - cost = 7500 - 8425 = -925

Profit = -925

The negative profit means the merchant lost money.

Answer: The merchant lost 575 dollars or whatever you call them.

Step-by-step explanation:

7500+175=7675

8250-7675= 575

Answer: Obtuse Triangle

Step-by-step explanation:

It is not right, because a^2 + b^2 doesn’t equal c^2. It is Actually obtuse because a^2 + b^2 is greater than c^2 because 20^2+50^2 =2900 which is greater than 2601 or 51^2.

Point A is an outlier because if we were to put the best fit line along with the points according to the most amount of points, point A is the farthest away from the line and thus is the outlier.

Answer:

They are decimal points.

Let's do

[tex]\\ \rm\Rrightarrow x+iy[/tex]

[tex]\\ \rm\Rrightarrow 0+0i[/tex]

Answer:

8

Step-by-step explanation:

Integers are whole numbers or opposite of whole numbers.

The slope is 111/11.

How?

Change of y is 1000-1=999.

Change of x is 100-1=99.

The slope is 999/99=111/11.

So if we start at (1,1) and we rise 111 and run 11 right, we get (12,112).

*Rise effects y and run effects x.

If we do that again from (12,112) we get (23,223).

Following the pattern of going up 111 and right 11 from each new location discovered we get all the of these points:

Start (1,1)

(12,112)

(23,223)

(34,334)

(45,445)

(56,556)

(67, 667)

(78, 778)

(89, 889)

(100, 1000) which is the end.

So we just need to count tthe points between begin point and end point which is 8 points.

3x3 = 9

9+1 = 10

Therefore 3 is the answer

Note*

To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. To evaluate, substitute 3 for x in the expression, and then simplify.

By simplifying given statement we got that if the quotient of [tex]8.4\times10^ 9[/tex] and a number n results in [tex]5. 6\times 10 ^{27}[/tex] then n is equal to [tex]1.5\times10^{-18}[/tex]

Result obtained after division is called quotient

Here given that "The quotient of 8. 4 times 10 Superscript 9 and a number n results in 5. 6 times 10 Superscript 27"

We can write it as

The quotient of [tex]8.4\times10^ 9[/tex] and a number n results in [tex]5. 6\times 10 ^{27}[/tex]

we can write it as

[tex]\frac{8.4\times10^ 9}{n} =5. 6\times 10 ^{27}[/tex]

Now we can simplify it as

[tex]n= \frac{8.4\times10^ 9}{5. 6\times 10 ^{27}} \\\\n= \frac{8.4}{5.6} \times\frac{10^9}{10^27} \\\\n= 1.5\times 10^{-18}[/tex]

By simplifying given statement we got that if the quotient of [tex]8.4\times10^ 9[/tex] and a number n results in [tex]5. 6\times 10 ^{27}[/tex] then n is equal to [tex]1.5\times10^{-18}[/tex]
