Answer: The population is 730 and the sample is 102.

Step-by-step explanation:

When we have a given set of elements, N elements, the population is N.

And if we do statistics with A of these N elements, the sample is A.

In this case, the population is the set of the 730 drivers, then the population is 730.

And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).

Then the sample will be 102.

Then the correct option is:

The population is 730 and the sample is 102.

Answer:

1) The equation of the line is y =  \(\frac{-1}{2}\) x + 4

2) The equation of the line is y = -12x + 8

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

Let us solve the two questions

1)

∵ points (-2, 5) and (2, 3) lie on the same line

→ Find the slope m

∵ Δ x = 2 - (-2) = 2 + 2 = 4

∵ Δ y = 3 - 5 = -2

∴ m = \(\frac{-2}{4}=\frac{-1}{2}\)

∴ The slope of the line is \(\frac{-1}{2}\)

→ Substitute the value of m in the form of the equation above

∴ y =  \(\frac{-1}{2}\) x + b

→ To find b substitute the x and y in the equation by the coordinates

   of a point on the line

∵ Point (-2, 5) lies on the line

∴ x = -2 and y = 5

∵ 5 =  \(\frac{-1}{2}\)(-2) + b

∴ 5 = 1 + b

- Subtract 1 from both sides

∴ 5 - 1 = 1 - 1 + b

∴ 4 = b

→ Sustitute it in the equation

∴ y =  \(\frac{-1}{2}\) x + 4

The equation of the line is y =  \(\frac{-1}{2}\) x + 4

2)

∵ The slope of the line is -12

∴ m = -12

∵ The line passes through point (0, 8)

∵ b is the value of y at x = 0

∴ b = 8

→ Substitute the values of m and b in the form of the equation above

∴ y = -12x + 8

The equation of the line is y = -12x + 8

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

To find the probability of at least one head in two flips of a coin, we can use the complement rule. The complement of the event "at least one head" is "no heads."

The probability of getting no heads in two flips of a coin is (1/2) x (1/2) = 1/4.

Therefore, the probability of getting at least one head in two flips of a coin is:

1 - (probability of no heads) = 1 - 1/4 = 3/4

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

In other words, if you flip a coin twice, the probability of getting at least one head is relatively high, and you are more likely to get at least one head than to get no heads at all.

Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.

here, we have,

Given the rule of transformation:

(x, y) → (x+2, y+3)

If we move horizontally 2 units to the right, 2 is added to the x-coordinate of any given point, and then 3 units up.

In other words,

(x, y) → (x+2, y+3) means Translation 2 units right and 3 units up.

For example,

Let say if we have the point A(4, 5)

Using the translation rule:

(x, y) → (x+2, y+3)

A(4, 5) → A'(4 + 2, 5 + 3) → A'(6, 8)

Therefore, the new position of A(4, 5) after translating 3 units right and 2 units up would be: A'(6,8).

Hence, (x, y) → (x+2, y+3) means a translation 2 units to the right and 3 units up.

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.

To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.

The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.

When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.

Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.

Therefore, the water will be approximately 7 inches deep in the larger container.

The z-score for the value 63.49 is approximately 0.24.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

Yes, it is possible to calculate a z-score for the value 63.49 assuming that the data follows a normal distribution.

The z-score measures the number of standard deviations a data point is away from the mean of the distribution. To calculate the z-score, we first need to calculate the mean and standard deviation of the dataset.

The mean can be calculated by adding up all the values and dividing by the total number of values:

Mean = (59 + 60 + 61 + 62 + 62 + 63 + 63 + 63 + 64 + 64 + 65 + 66 + 67 + 68) / 14 = 63

The standard deviation can be calculated using the following formula:

Standard deviation = sqrt((1/N) * sum((xi - x_mean)²))

where N is the number of values, xi is each value in the dataset, and x_mean is the mean of the dataset.

Using this formula, we can calculate the standard deviation of the dataset:

Standard deviation = sqrt((1/14) * ((59 - 63)² + (60 - 63)² + ... + (68 - 63)²))

Standard deviation ≈ 2.02

Now we can calculate the z-score for the value 63.49 using the following formula:

z-score = (x - x_mean) / standard deviation

where x is the value we want to calculate the z-score for.

z-score = (63.49 - 63) / 2.02 ≈ 0.24

Therefore, the z-score for the value 63.49 is approximately 0.24.

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly can be calculated as follows:

Given, Principal = Rs 1200Time = 1.5 yearsInterest rate = 40% per annum, compounded quarterly

Let r be the quarterly rate of interest. Then we can convert the annual interest rate to quarterly interest rate using the following formula: \text{Annual interest rate} = (1 + \text{Quarterly rate})^4 - 1$$

Substituting the values, we get:0.40 = (1 + r)^4 - 1 Solving for r, we get:r = 0.095 or 9.5% per quarter

Now, we can use the formula for the amount of money after time t, compounded quarterly: $A = P \left( 1 + \frac{r}{4} \right)^{4t}

Substituting the values, we get:A = Rs 1200 x $\left(1 + \frac{0.095}{4} \right)^{4 \times 1.5}= Rs 1893.09

Therefore, the amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

When operating under Instrument Flight Rules (IFR) with a Visual Flight Rules (VFR) on-top clearance, the altitude to be maintained depends on the specific clearance and regulations in place.

Generally, when flying VFR-on-top, the pilot is authorized to operate in VFR conditions above a layer of clouds or other obscuring phenomena. In terms of altitude, the pilot is expected to maintain a cruising altitude appropriate for the direction of flight and comply with the relevant airspace regulations. This typically involves flying at the appropriate altitude for the specific airspace class, as defined by the Federal Aviation Regulations (FARs) or the applicable regulatory authority. It's important for pilots to review and understand the specific requirements and altitude restrictions outlined in their VFR-on-top clearance, as well as any additional instructions provided by air traffic control.

The estimated values of f '(0), f '(1/2), f '(2), f '(3), and f '(4) are approximately 0, positive, greater, greater, and greater, respectively, based on the graph of f(x) = \(x^{3}\)

By analyzing the graph of f(x) = x^3, we can estimate the values of the derivatives f '(0), f '(1/2), f '(2), f '(3), and f '(4) by zooming in on the graph using a graphing device.

When x is close to 0, the slope of the graph of f(x) is also close to 0. Therefore, we can estimate that f '(0) is approximately 0.

Similarly, when x is close to 1/2, the slope of the graph of f(x) is positive and relatively steep. Hence, we can estimate that f '(1/2) is a positive value.

As x increases, the slope of the graph of f(x) becomes steeper. Therefore, we can estimate that f '(2) is greater than f '(1/2) and f '(3) is greater than f '(2).

Finally, as x gets larger, the slope of the graph of f(x) continues to increase but at a decreasing rate. Hence, we can estimate that f '(4) is greater than f '(3) but less than f '(2).

By zooming in on the graph of f(x) using a graphing device, we can obtain more accurate estimations for the values of f '(0), f '(1/2), f '(2), f '(3), and f '(4).

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200
