The test statistic for this scenario is 1.14. To calculate the test statistic, we can use the formula:

(test statistic) = (sample proportion - hypothesized proportion) / standard error

Here, the hypothesized proportion is the national proportion of red cars on the road, which is 0.12. The sample proportion is the proportion of red cars in the sample, which is 35/210 = 0.167.

To calculate the standard error, we use the formula:

\(standard error=\sqrt{\frac{(hypothesized proportion * (1 - hypothesized proportion)) }{ sample size} }\)

Plugging in the values, we get:

standard error = √[(0.12 * (1 - 0.12)) / 210] = 0.032

Now, we can calculate the test statistic:

test statistic = (0.167 - 0.12) / 0.032 = 1.14

The test statistic tells us how many standard errors the sample proportion is away from the hypothesized proportion. In this case, the test statistic is 1.14, which means that the sample proportion of Phillies fans driving red cars is 1.14 standard errors away from the national proportion of red cars on the road. We would need to compare this test statistic to a critical value from a t-distribution to determine if the difference is statistically significant at a given level of significance.

The input value that produces the same output value for f(x) and g(x) on the graph is x = 1.To find the input value that produces the same output value for both functions, we need to determine the x-coordinate of the point(s) where the two lines intersect.

These points represent the values of x where f(x) and g(x) are equal.

The line labeled f(x) passes through the points (-2, 4), (0, 2), and (1, 1). Using these points, we can determine the equation of the line using the slope-intercept form (y = mx + b). Calculating the slope, we get:

m = (2 - 4) / (0 - (-2)) = -2 / 2 = -1

Substituting the point (0, 2) into the equation, we can find the y-intercept (b):

2 = -1(0) + b

b = 2

Therefore, the equation for f(x) is y = -x + 2.

Similarly, for the line labeled g(x), we can use the points (-3, -3), (0, 0), and (1, 1) to determine the equation. The slope is:

m = (0 - (-3)) / (0 - (-3)) = 3 / 3 = 1

Substituting (0, 0) into the equation, we can find the y-intercept:

0 = 1(0) + b

b = 0

Thus, the equation for g(x) is y = x.

To find the input value that produces the same output for both functions, we can set the two equations equal to each other and solve for x:

-x + 2 = x

Simplifying the equation:

2x = 2

x = 1.

Therefore, the solution to the differential equation with the given initial condition is: u(t) = -1/4 ln(6t² + e⁻⁶⁸)) - 1/4 ln(2).

Initial value problems are another name for differential equations with initial conditions. The example dydx=cos(x)y(0)=1 is used in the video up above to demonstrate a straightforward starting value issue. You get y=sin(x)+C by solving the differential equation without the initial condition.

For the separable differential equation to be solved:

\(u du/dt = e^(4u) 6t\)

The variables can be rearranged and divided:

\(u du e^(-4u) du = 6t dt\)

Integrating both sides, we get:

\((1/2)e^(-4u) = 3t^2 + C\)

where C is the integration constant. We utilise the initial condition u(0) = 17 to determine C:

\((1/2)e^(-4(17)) = 3(0)^2 + CC = (1/2)e^(-68)\)

When we put this C value back into the equation, we get:

\((1/2)e^(-4u) = 3t^2 + (1/2)e^(-68)\)

After taking the natural logarithm and multiplying both sides by 2, we arrive at:

\(-4u = ln(6t^2 + e^(-68)) + ln(2)\)

Simplifying, we have:

\(u = -1/4 ln(6t^2 + e^(-68)) - 1/4 ln(2)\)

Adding 10 to every value in the data set does not affect the standard deviation.

Given data set:

X: 40, 30, 45, 35, 25

Calculate the mean (x-bar):

Mean = (40 + 30 + 45 + 35 + 25) / 5 = 175 / 5 = 35

Calculate the deviations from the mean (x - x-bar):

(x - x-bar) = 40 - 35 = 5

(x - x-bar) = 30 - 35 = -5

(x - x-bar) = 45 - 35 = 10

(x - x-bar) = 35 - 35 = 0

(x - x-bar) = 25 - 35 = -10

Square the deviations [(x - x-bar)²]:

(x - x-bar) = 5² = 25

(x - x-bar)² = (-5)² = 25

(x - x-bar)² = 10² = 100

(x - x-bar)² = 0² = 0

(x - x-bar)² = (-10)² = 100

Calculate the sum of the squared deviations:

Sum of (x - x-bar)² = 25 + 25 + 100 + 0 + 100 = 250

Now, Variance = (Sum of (x - x-bar)²) / (n - 1) = 250 / 4 = 62.5

Standard Deviation = √Variance = √62.5 ≈ 7.91

Now, let's add 10 to every value in the data set:

New data set:

X: 50, 40, 55, 45, 35

New Mean = (50 + 40 + 55 + 45 + 35) / 5 = 225 / 5 = 45

Calculate the new deviations from the new mean:

(x - x-bar) = 50 - 45 = 5

(x - x-bar) = 40 - 45 = -5

(x - x-bar) = 55 - 45 = 10

(x - x-bar) = 45 - 45 = 0

(x - x-bar) = 35 - 45 = -10

Square the new deviations [(x - x-bar)²]:

(x - x-bar)² = 5² = 25

(x - x-bar)² = (-5)² = 25

(x - x-bar)² = 10² = 100

(x - x-bar)² = 0² = 0

(x - x-bar)² = (-10)² = 100

Calculate the new sum of squared deviations:

Sum of (x - x-bar)² = 25 + 25 + 100 + 0 + 100 = 250

Calculate the new variance:

New Variance = (Sum of (x - x-bar)) / (n - 1) = 250 / 4 = 62.5

Answer:

The number of best sellers on the shelf are 13.333 best sellers

Step-by-step explanation:

The question is a word problem with the following specifications;

Proportion of the books, B, on the shelf that are number 1 best seller = 1/2 of B

Proportion of the books that are Number 3 book = 1/4 of (1 - 1/2) of B

Proportion of the books that are Number 2 book = 1/2 - 1/4 of (1 - 1/2) of B

Given that there are 5 copies of Number 2 book we have;

1/2 - 1/4 × (1 - 1/2) × B = 3/8 × B = 5

Which gives the number of best sellers on the shelf as B = 40/3 books

If there is a grammatical misunderstanding, we should have;

There appear to be an error in grammar as the statement maybe should have read as follows

Half of the books on he shelf are copes of the Number 1 best seller. The remainder are 1/4 copies of the Number 3 book.....

Which gives;

Proportion of the books that are Number 3 book = 1/4 of B

Proportion of the books that are Number 2 book = (1 - 1/2 - 1/4) of B

Given that there are 5 copies of Number 2 book we have;

(1 - 1/2 - 1/4) × B = 1/4 × B = 5

Which gives the number of best sellers on the shelf as B = 20 books.

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

To calculate log manually, the Taylor or Maclaurin series is generally used.

An accurate method to calculate the value of logarithms would be.

If we need to calculate the value log(25) as an example:

1) Divide 25 by the nearest power of 10. The condition must be 25 ≥ 10n.

2) The value of n is 1 because 25 ≥ 101. So the initial answer is 1.xxxxxx.

3) Divide 25 by 101. The result is 2.5.

4) Raise 2.5 by 10. So 2.510 ≈ 9536.7

(The number is raised to 10)

5) For the next values, the same process will be used.

6) Divide 9536.7 by the nearest power of 10.

7) 9536.7 ≥ 103 so n=3. The answer is now 1.3xxxxx.

8) 9536.7 / 103 = 9.5367

9) Raise 9.5367 to 10. 9.536710 = 6222733625

10) 6222733625 ≥ 10n so n=9. The answer is now 1.39xxxx.

11) Repeat the same process until you get the desired precision.

12) So log (25) ≈ 1.39794.
