The decision to reject or not reject the null hypothesis depends on the chosen significance level. The smaller the significance level, the stronger the evidence needed to reject the null hypothesis.

In hypothesis testing, the significance level is the probability of rejecting the null hypothesis when it is true. It is usually set at 0.05 or 0.01. The P-value is the probability of obtaining a test statistic as extreme as the one observed, assuming the null hypothesis is true.

For a P-value of 0.081, we can say that there is some evidence against the null hypothesis but not strong enough to reject it.

If the significance level is set at 0.05, we should not reject the null hypothesis because the P-value is greater than the significance level.

However, if the significance level is set at 0.10, we may choose to reject the null hypothesis because the P-value is equal to or less than the significance level.

For part a, since the alpha level is 0.10, the null hypothesis should be rejected if the P-value is less than or equal to 0.10. Since the P-value is 0.081, which is greater than 0.10, we do not reject the null hypothesis. Therefore, the answer is B.

For part b, since the alpha level is 0.05, the null hypothesis should be rejected if the P-value is less than or equal to 0.05. Since the P-value is 0.081, which is greater than 0.05, we do not reject the null hypothesis. Therefore, the answer is C. In hypothesis testing, the null hypothesis is a statement that assumes there is no significant difference between the sample data and the population data. The hypothesis test is used to determine the validity of the null hypothesis by calculating the probability of observing the sample data if the null hypothesis is true. The significance level is the threshold value used to determine whether to reject the null hypothesis. It is usually set to 0.05 or 0.01. The P-value is the probability of obtaining a test statistic as extreme as or more extreme than the one observed, assuming the null hypothesis is true. If the P-value is less than or equal to the significance level, we reject the null hypothesis. Otherwise, we do not reject it.

Answer:

the answer would be 12/5

Answer:

29% of the drive

Step-by-step explanation:

The plot of the problem is:

Transmitter at origin (0,0)  

City to the north at (0,70)

City to the east at (74,0)

The path from city to city is a line with slope:

m = (-70)/74 = -35/37

and y-intercept at y = 70, so the equation is y = (-35/37)*x + 70.

The transmitter reach the area enclosed by the next circle:

x^2 + y^2 = 53^2

See the picture attached

The intersection is gotten from the picture or solving:

x^2 + [(-35/37)*x + 70]^2 = 53^2

the points approximately are: (24.1, 47.2) and (45.8, 26.7)

From Pythagorean theorem the total distance of the trip is:

d1 = √(70^2 + 74^2) ≈ 101.9 miles

And the distance when the signal is picked up is:

d2 =√ [(45.8 - 24.1)^2 + (47.2 - 26.7)^2] ≈ 29.9 miles

You will pick up a signal from the transmitter in (d2/d1)*100 = 29% of the drive.

The coordinates of point D 0.25 x-axis for the points A(2, 6), B(0, 0), C(-5, 8), and D(-2, 10) are (-2, -2.5) when point D is reflected across the x-axis. This is obtained by negating the y-coordinate of point D and keeping the x-coordinate the same.

To find the coordinates of point D 0.25 x-axis, we need to reflect point D across the x-axis. This will result in the y-coordinate of point D being negated while the x-coordinate remains the same.

The coordinates of point D are (-2, 10), so when we reflect it across the x-axis, we get the new coordinates:

D 0.25 x-axis = (-2, -10/4) = (-2, -2.5)

Therefore, the coordinates of point D0.25∘rx-axis for the given points A, B, C, and D are (-2, -2.5).

The coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).

What is transformation of points?

The reflection is the kind of transformation that takes place whenever a shape's points cross a line. When the points are reflected over a line, the image is on the opposite side of the line from the pre-image and is located at the same distance from the line. The image point is reflected from each point (p, q).

Given:

Quadrilateral ABCD has coordinates A(−2, 0), B(0, 4), C(4, 6), and D(2, 2).

First to find the coordinates after applying the transformation  

(x, y) ⟶ (–x, y).

So,

A(-2, 0) ⟶ A'(2, 0)

B(0, 4) ⟶ B'(0, 4)

C(4, 6) ⟶ C'(-4, 6)

D(2, 2) ⟶ D'(-2, 2)

Now applying the transformation (x, y) ⟶ (x, –y)

A'(2, 0) ⟶ A"(2, 0)

B'(0, 4) ⟶ B"(0, -4)

C'(-4, 6) ⟶ C"(-4, -6)

D'(-2, 2) ⟶ D"(-2, -2)

Hence, the coordinates of the image of ABCD after applying the given transformation are, A"(2, 0), B"(0, -4), C"(-4, -6), and D"(-2, -2).

The minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.

Given that a box contains 6 red, 8 green, 10 blue, 12 yellow, and 15 white balls.

As the question says that the minimum number of balls chosen must ensure that we get 9 balls of the same color, so we must consider the balls of those colors which are more than 9 in number.

Here, 10 blue, 12 yellow, and 15 white balls are considered as they are more than 9.

By applying the Pigeon principle,

we can get.,

9 blue + 9 yellow + 9 white – 3 + 1 = 25

As we are picking randomly so we can get all the red and green balls before the above 25 balls.

Therefore we add the balls 6 red + 8 green + 25 = 39

Hence, the minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.

Two values have frequency 2, so both are modes. They are 5 and 6. Therefore, the mode is 5 and 6.

Given measure: 3, 5, 4, 6, 10, 5, 6, 9, 2, 13.(D) To calculate \(x_2\), first we need to sort the data in ascending order: 2, 3, 4, 5, 5, 6, 6, 9, 10, 13

Now, we need to find the median, which is the middle value of the data. Since the data has even number of values, we will calculate the mean of middle two values, that is:(5+6)/2 = 5.5 Therefore, \(x_2 = 5.5\).\( \frac{2}{x}= \) To find the value of x, we will first cross-multiply and then take the reciprocal of both sides:\[\frac{2}{x} = y \Rightarrow 2 = xy \Rightarrow x = \frac{2}{y}\] Therefore, \( \frac{2}{x}= \frac{2}{y}\).

(b) To calculate Fried m, we will use the formula: \[f_m = L + \frac{(n/2 - F)}{f} \times c\]where L is the lower limit of the modal class, F is the cumulative frequency of the class preceding the modal class, f is the frequency of the modal class, c is the class interval, and n is the total number of values.

First, we will calculate the class interval:c = (upper limit of class - lower limit of class) = (7-6) = 1 Next, we will construct a frequency table to find the modal class:| Class Interval | Frequency ||-------------------|------------|| 2-3 | 1 || 3-4 | 1 || 4-5 | 1 || 5-6 | 2 || 6-7 | 2 || 7-8 | 1 || 9-10 | 1 || 10-11 | 1 || 13-14 | 1 |The modal class is the class with highest frequency.

Here, two classes have frequency 2, so both are modes. They are 5-6 and 6-7.

Therefore, L = 5, F = 2, f = 2, n = 10, and c = 1. Substituting the values, we get:\[f_m = L + \frac{(n/2 - F)}{f} \times c = 5 + \frac{(10/2 - 2)}{2} \times 1 = 7\] Therefore, Fried m = 7.

(c) To find the mode, we look for the value(s) with highest frequency. Here, two values have frequency 2, so both are modes. They are 5 and 6. Therefore, the mode is 5 and 6.

Answer:

(8, - 1 )

Step-by-step explanation:

x - 2y = 10 → (1)

x + 3y = 5 → (2)

subtract (2) from (1) term by term to eliminate x

(x - x) + (- 2y - 3y) = 10 - 5

0 + (- 5y) = 5

- 5y = 5 ( divide both sides by - 5 )

y = - 1

substitute y = - 1 into either of the 2 equations and solve for x

substituting into (2)

x + 3(- 1) = 5

x - 3 = 5 ( add 3 to both sides )

x = 8

solution is (8, - 1 )

Answer:

x = 8, y = -1.

Step-by-step explanation:

x - 2y = 10

x + 3y = 5      Subtracting this equation from the first one:

0 - 5y = 5

y = -1

Plug y = -1 in the second equation:

x + 3(-1) = 5

x - 3 = 5

x = 5 + 3

x = 8.

The miles will be around 303 miles, both Uhaul and Penske will have the same total cost.

To determine at what point both companies have the same total cost, we need to set up an equation.

Let x be the number of miles driven.
For Uhaul, the cost will be $50 + $0.99x.
For Penske, the cost will be $350.
Setting these two expressions equal to each other, we get:
$50 + $0.99x = $350
Simplifying this equation, we get:
$0.99x = $300
U-Haul: Cost_UH = 50 + 0.99 * miles

Penske: Cost_P = 350

Set the equations equal to each other to find the number of miles where the costs are equal.

50 + 0.99 * miles = 350

Solve for the number of miles.

0.99 * miles = 350 - 50 0.99 * miles = 300 miles = 300 / 0.99

Calculate the number of miles and round to the nearest whole number if needed.

miles ≈ 303

So,

At approximately 303 miles, both companies will have the same total cost for renting a truck for one day.
Dividing both sides by $0.99, we get:
x ≈ 303.03

It is important to note that this calculation assumes that the only cost for Uhaul is the rental fee and mileage charge, and does not include any additional fees or charges that may be incurred during the rental period.

It is also important to consider other factors such as the availability of trucks, customer service, and any additional services offered by the rental companies before making a final decision.

Step-by-step explanation:

By definition, a function relates each element in the domain to only one element in the range. This means that each vertical line you draw through the x-axis can intersect the function at only one point. ... y = 2x +1. This is the equation of a straight line with slope 2 and y-intercept 1, so it is a function.
