​

Answer:

yes

Step-by-step explanation:

yes

Answer:

Option (2).

Step-by-step explanation:

Let f(x) and g(x) are the two functions with domain A and B.

Then (fg)(x) will be the function with domain A∩B

(fg)(x) = f(x)g(x)   Domain : A∩B

In this question two functions are,

c(x) = \(\frac{5}{(x-2)}\) and d(x) = (x + 3)

Domain : (x - 2) > 0 ⇒ x > 2

              and (x - 2) < 0 ⇒ x < 2

Or domain of (cd)(x) will be C = (-∞, 2)∪(2, ∞).

Similarly, d(x) = x + 3

Domain : All real numbers

             : D = (-∞, ∞)

(cd)(x) = c(x)d(x)

          = \(\frac{5}{(x-2)}\times (x+3)\)

Domain of (cd)(x) will be,

Domain : C∩D = (-∞, 2)∪(2, ∞) ∩ (-∞, ∞)

             : (-∞, 2) ∩ (2, ∞)

Therefore, domain of (cd)(x) will be all real values except 2.

Option (2) will be the answer.

Answer:

The equation of the perpendicular line (PR) to line PQ is; y = -0.5x - 1.5

Step-by-step explanation:

The line is perpendicular to line adjoined by points P(-3,0) and Q(0,6)

The slope of line PQ is;

Slope = change in y ÷ change in x = \(\frac{6 - 0}{0 -- 3}\) = 2

The product of slopes of two perpendicular lines = -1

Hence the slope of line PR = -1 ÷ slope of line PQ = -1/2

Taking another point (x,y) and point P(-3,0) the equation of line PR is;

Slope = \(\frac{y - 0}{x - -3} = -\frac{1}{2}\)

Cross-multiplying gives;

2y = -x - 3 , y = -x/2 - 3/2 , y = -0.5x - 1.5

Based on the given confidence interval, the null hypotheses (c) and (d) can be rejected at the 5% significance level.

To determine which null hypothesis can be rejected at the 5% significance level, we need to compare it with the confidence interval.

The 99% confidence interval (9, 15) means that we are 99% confident that the true population mean falls between 9 and 15.

At the 5% significance level, we reject a null hypothesis when the hypothesized value falls outside the confidence interval.

Let's analyze each option:

(a) The population mean is less than or equal to 15.

Since the upper bound of the confidence interval is 15, this null hypothesis cannot be rejected.

(b) The population mean is greater than or equal to 9.

Since the lower bound of the confidence interval is 9, this null hypothesis cannot be rejected.

(c) The population mean is greater than or equal to 15.

Since the lower bound of the confidence interval is 9, which is less than 15, this null hypothesis can be rejected.

(d) The population mean is 12.

Since the null hypothesis specifies a specific value (12), and the confidence interval (9, 15) does not include 12, this null hypothesis can be rejected.

Based on the given confidence interval, the null hypotheses (c) and (d) can be rejected at the 5% significance level.

The probability of at least 4 of the next 5 flights being overbooked is 1.0%.

The probability of an event occurring is determined by analyzing the data from a sample.

A histogram is often used to visualize the distribution of data, which can be used to calculate the probability of an event occurring.

By examining the histogram, you can determine the probability of a certain event occurring based on the height of the corresponding bar in the graph.

From the histogram, it is clear that the probability of at least 4 of the next 5 flights being overbooked is 1.0%.

This is because there is only one bar in the histogram that corresponds to the probability of 4 out of 5 flights being overbooked.

This bar has a height of 1.0%, which indicates a 1.0% probability of at least 4 out of 5 flights being overbooked.

Step-by-step explanation:

Answer:

It says double, so it means that:

_____ x 2 = 50

In order to find _____, you must reverse the equation.

50 / 2 = _______

This means that:

50 / 2 = 25

So, ______ = 25

Answer:

Your number is 25.

Step-by-step explanation:

If you divide 50 by two, or basically the opposite of doubling a number, you get 25. To confirm this, 25 multiplied by 2, or 25 doubled, is equivalent to 50.

Kristen is attempting to solve the equation \(0=\sqrt{6x}-x\). Hence, option b. is the correct answer.

A radical equation has no solution if the square root of a negative number is involved in the equation. The left-hand side of equation b, √(6x), is always non-negative. But the right-hand side, -x, can be negative. So, there is no value of x that can satisfy the equation.

In other words, there is no real number x that would make the left-hand side equal to the right-hand side, so equation b has no solution.

Hence, Kristen is attempting to solve equation 0 = √(6x) - x.

In circle f, segment eb is a diameter that divides the circle into two equal sectors. The length of segment fb is 3 units, so the radius of the circle is 3 units.

To find the area of one of the sectors in circle f, we need to know the radius of the circle. Since a diameter of the circle is segment eb, and the length of segment fb is 3 units, then the radius of the circle is 3 units. To find the area of one sector, we can use the formula A = (1/2)r^2, where r is the radius. In this case, the radius is 3 units, so the area of one sector is A = (1/2)(3^2), or A = 4.5 units^2. To find the area of the whole circle, we can multiply the area of one sector by 2, since there are two equal sectors in the circle. Thus, the area of the whole circle is A = 2(4.5) = 9 units^2.

The answer is 50 grams of salt in the tank at all times.

To find the number of grams of salt in the tank at time t, we need to use the formula:

a(t) = a(0) + (r - p) * t

where a(0) is the initial amount of salt in the tank, r is the rate at which brine is being pumped into the tank, p is the rate at which the solution is being pumped out of the tank, and t is the time elapsed.

In this case, a(0) = 50 grams, r = 3 grams per minute (since the brine contains 1 gram of salt per liter and 3 liters are being pumped in per minute, so 3 grams of salt are being added per minute), and p = 3 grams per minute (since the solution is being pumped out at the same rate as it is being pumped in). Therefore, we can simplify the formula to:

a(t) = 50 + 0 * t
a(t) = 50 grams

This means that the amount of salt in the tank remains constant over time, since the rate at which it is being pumped in and out is equal. Therefore, the answer is 50 grams of salt in the tank at all times.

Because of the size of the black section,

Answer:

a = 44° , b = 136°

Step-by-step explanation:

a and Θ are alternate angles and are congruent , so

a = 44°

b and Θ are same- side interior angles and sum to 180°, that is

b + Θ = 180°

b + 44° = 180° ( subtract 44° from both sides )

b = 136°
