The hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.To convert the hybrid car's fuel consumption rate from miles/gallon to kilometers/liter, we need to multiply by a conversion factor of 0.425 (1 mile = 1.609 kilometers, 1 gallon = 3.785 liters).

So the car's fuel consumption rate is 54.1 miles/gallon x 0.425 km/mile ÷ 3.785 liters/gallon = 6.09 km/liter.To find how many liters of gasoline the car will consume traveling 132 km, we can use the formula:

Gasoline consumed = distance traveled ÷ fuel consumption rate

Gasoline consumed = 132 km ÷ 6.09 km/liter = 21.65 liters (rounded to two decimal places).Therefore, the hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.

Answer:

-1.5

Step-by-step explanation:

The gradient of a line can be found using the formula:

gradient = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

So for the line that passes through (3, 7) and (1, 10), the gradient can be found as:

gradient = (10 - 7) / (1 - 3)

gradient = 3 / -2

gradient = -1.5

So the gradient of the line that passes through (3, 7) and (1, 10) is -1.5.

The solution is Option B.

The angles ∠2 and ∠7 are alternate exterior angles

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

Let the parallel lines be represented as m and n

Now , the transversal line is t

The angles formed on line m is ∠1 , ∠2 , ∠3 and ∠4

And , the angles formed on line n is ∠5 , ∠6 , ∠7 and ∠8

Now , the angles ∠2 and ∠7 are situated outside or exterior and is represented by alternate exterior angles

So , pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

The answer is c. Statistic because the value is a numerical measurement describing a characteristic of a sample.

A statistic is a value that summarizes a characteristic of a sample. In this case, the percentage of employees in the sample who own a television (45%) is a statistic because it summarizes a characteristic of the sample of employees that was selected. A parameter, on the other hand, is a value that summarizes a characteristic of a population. For example, if we were to consider the percentage of all employees in the company who own a television, then the mean or median percentage of television ownership would be a parameter because it would describe a characteristic of the entire population of employees.

Answer:  Therefore, we purchased 4 adult tickets and 7 child's tickets.

Step-by-step explanation:

Through the information provided, we set up a system equation:

a + c = 11

7.50a + 5.00c = 65

By the first equation, we convert it into a form, then we get a = 11 - c. Then we plug in the a = 11 - c to the second equation:

  7.50(11 - c) + 5.00c = 65

82.5 - 7.50c + 5.00c = 65

            82.5 - 2.50c = 65

                     - 2.50c = 65 - 82.5

                     - 2.50c = - 17.5

                               c = - 17.5/- 2.50

                               c = 7

And we plug c = 7 back into the first equation, which is a + c = 11.

a + c = 11

a + 7 = 11

      a = 11 - 7

      a = 4

Therefore, we purchased 4 adult tickets and 7 child's ticket.

Part (a)

4/15 is the probability of getting a rotten orange

After one is taken and not put back, there are

meaning 3/14 is the probability of a second rotten orange.

Two rotten in a row has the probability (4/15)*(3/14) = 2/35. I skipped a few steps so let me know if you need to see in more detail how I got to that result.

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

Part (b)

We want to calculate the probability exactly one of the two oranges selected is rotten.

There are two possible cases here:

Let's determine the probability for case 1.

4/15 was mentioned earlier in part (a) as the probability of a rotten orange. There are 15-4 = 11 non-rotten oranges and 15-1 = 14 remaining since we aren't replacing the first selection. That gives 11/14 as the probability the 2nd selection is fresh.

We get (4/15)*(11/14) = 22/105 as the probability for case 1 to happen.

Through similar calculations, the probability for case 2 is (11/15)*(4/14) = 22/105

Cases 1 and 2 are mutually exclusive. Both cannot happen simultaneously. There is no overlap. This fact allows us to add the results to get:

22/105 + 22/105 = 44/105

That fraction cannot be reduced.

The board should be 28 inches long.

What is an expression?

An expression or mathematical expression in mathematics is a finite combination of symbols that is well-formed in accordance with context-dependent principles.

Let's call the length of the first part "x". Then, the length of the second part would be x + 6 inches. The total length of both parts is 50 inches, so we can set up an equation to solve for x:

x + (x + 6) = 50

Expanding and solving for x:

2x + 6 = 50

2x = 44

x = 22

So, the first part should be 22 inches long, and the second part should be 22 + 6 = 28 inches long.

The calculated test statistic (t = -0.527) is not less than -1.894 or greater than 1.894.

A hypothesis test can be performed to determine whether the mean volume of beverage in the cans differs from 12 ounces using the following steps:

(1)State the null hypothesis and the alternative hypothesis.

The null hypothesis is that the mean volume of beverage in the cans is equal to 12 ounces (μ = 12). The alternative hypothesis is that the mean volume of beverage in the cans is not equal to 12 ounces (μ ≠ 12).

(2)Select a level of significance (α).

In this case, the level of significance is α = 0.05.

(3)Calculate the sample mean and standard deviation.

The sample mean can be calculated as:

mean = (11.96 + 12.10 + 12.04 + 12.13 + 11.98 + 12.05 + 11.91 + 12.03) / 8 = 12.04375

The sample standard deviation can be calculated as:

[tex]s=\sqrt((11.96 - 12.04375)^2 + (12.10 - 12.04375)^2 + (12.04 - 12.04375)^2 + (12.13 - 12.04375)^2 + (11.98 - 12.04375)^2 + (12.05 - 12.04375)^2 + (11.91 - 12.04375)^2 + (12.03 - 12.04375)^2) / (8 - 1))[/tex] [tex]s=0.277764079[/tex]

(4)Calculate the test statistic.

The test statistic can be calculated as:

t = (mean - 12) / (s / sqrt(8))

(5)Determine the critical value(s) from the t-distribution table with 7 degrees of freedom (8 - 1).

At a significance level of 0.05 and 7 degrees of freedom, the critical value from the t-distribution table is approximately ±1.894.

(6)Compare the test statistic to the critical value(s).

If the test statistic is less than -1.894 or greater than 1.894, then the null hypothesis can be rejected. Otherwise, the null hypothesis cannot be rejected.

(7)Conclude the hypothesis test.

In this case, the calculated test statistic (t = -0.527) is not less than -1.894 or greater than 1.894. Therefore, we cannot reject the null hypothesis. This means that there is not enough evidence to conclude that the mean volume of beverage in the cans is different from 12 ounces.

The instantaneous rate of change of R(t) at time t is the limit of the average rate of change of R(t) as h approaches 0. In this case, the instantaneous rate of change of R(t) at time t = 1 is R'(1) = 9000 dollars/day.

The average rate of change of a function is the ratio of how much the output of the function changes over a given period to the length of that period. We can calculate this for the function R(t) = 210 + 30t3 by considering the time intervals [t, t+h] at h = 1, 0.1 and 0.01 days.

For h = 1 day, the average rate of change of R(t) is 90 dollars/day. This can be calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+1)3 = 1080, by the length of the period, h = 1 day.

For h = 0.1 day, the average rate of change of R(t) is 900 dollars/day. This is calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+0.1)3 = 9, by the length of the period, h = 0.1 day.

For h = 0.01 day, the average rate of change of R(t) is 9000 dollars/day. This is calculated by dividing the difference in output of the function at t and t+h, i.e., 30t3+30(t+0.01)3 = 0.9, by the length of the period, h = 0.01 day.

The estimated quantity of dye left in a healthy pancreas 30 minutes after the injection, rounded to the closest hundredth of a grams, is 0.07 grams.

As per the question given,  

After the dye is injected, a healthy pancreas will secrete 4% of the remaining amount of dye each minute. Let's use exponential decay to model the amount of dye remaining in the pancreas over time.

The amount of dye remaining after t minutes can be expressed as:

R(t) = 0.3 * (1 - 0.04)^t

We want to find the amount of dye remaining after 30 minutes, so we can substitute t=30 into the equation and calculate:

R(30) = 0.3 * (1 - 0.04)^30

R(30) = 0.3 * (0.96)^30

R(30) = 0.3 * 0.2312
