The probability of awarding the scholarship to a student who is either a math major or an engineering major is 0.2787 .Option (c) is the correct answer.

In this question, we are asked to find the probability of awarding the scholarship to a student who is either a math major or an engineering major. Total students (n) = 61 Chemistry majors (C) = 23 Math majors (M) = 12 Engineering majors (E) = 9 Undecided (U) = 17Students with declared majors in Math and Engineering (M ∩ E) = 4

We have to find P(A) = P(student is either a math major or an engineering major).To solve this problem, we will use the addition rule of probability. The addition rule states that the probability of event A or B occurring equals the probability of event A plus the probability of event B minus the probability of both A and B occurring. P(A) = P(M ∪ E) = P(M) + P(E) - P(M ∩ E)

Here, P(M) = probability that the student is a math major= number of math majors / total students = 12/61 P(E) = probability that the student is an engineering major= number of engineering majors / total students = 9/61 P(M ∩ E) = probability that the student has declared both math and engineering majors = 4/61So,P(A) = P(M ∪ E) = P(M) + P(E) - P(M ∩ E)P(A) = 12/61 + 9/61 - 4/61= 17/61≈ 0.2787

The statements that is true is option C FG ⊥ HB and FG ║ DE, that is FG is perpendicular to HB and parallel to DE.

Geometry's use of parallel and perpendicular lines is crucial, and their distinctive qualities make it simple to distinguish between them. If two lines are in the same plane, are spaced equally apart, and never cross one another, they are said to be parallel. Perpendicular lines are those that cross at an angle of 90 degrees. Two straight lines are said to be parallel if they are located in the same plane and never cross one another. On the other hand, two lines are said to be perpendicular when they cross each other at a 90° angle.

From the given figure we observe that, the angle between the segments FG and HB is 90 degrees thus,

FG ⊥ HB.

Also, DE ⊥ HB, thus the segments FG ║ DE.

Hence, the statements that is true is option C FG ⊥ HB and FG ║ DE, that is FG is perpendicular to HB and parallel to DE.

The 95% confidence interval for the proportion of nonconforming items is (0.093, 0.250). This indicates that there is a 95% chance that the true proportion of nonconforming items lies between 9.3% and 25%.

To calculate the 95% confidence interval for the proportion of nonconforming items, we first calculate the sample proportion p of nonconforming items: p = 16/300 = 0.053.

Next, we calculate the standard error of the sample proportion, which is SE = √(p(1-p)/n) = √(0.053(1-0.053)/300) = 0.01.

Finally, we calculate the lower and upper limits of the 95% confidence interval for the proportion of nonconforming items by subtracting and adding 1.96 x SE to the sample proportion, respectively. This gives us the confidence interval of (0.093, 0.250).

Step-by-step explanation:

We can use the trigonometric function sine to determine the angle the ladder makes with the ground. Let's call this angle theta. We have:

sin(theta) = opposite/hypotenuse

where the opposite side is the height of the ladder on the wall (15 ft) and the hypotenuse is the length of the ladder (19 ft). Solving for theta, we get:

theta = sin^-1(15/19) ≈ 50.47°

Since this angle is less than 75°, the ladder will be safe at this height.

From the given data, the probability that the sample proportion is between 0.45 and 0.51 is approximately 0.7372 and between 0.42 and 0.54 is 0.9772.

To solve this problem, we can use the central limit theorem, which states that the distribution of sample proportions will be approximately normal for large sample sizes.

Given that the population proportion is p = 0.48 and the sample size is n = 350, we can calculate the standard error of the sample proportion as:

SE = √(p × (1 - p) / n) = √(0.48 × 0.52 / 350) = 0.025

We want to find the probability that the sample proportion is within three percentage points of the population proportion, or in other words, between 0.45 and 0.51. To do this, we can standardize the sample proportion using the standard error:

z = (P - p) / SE = (0.45 - 0.48) / 0.025 = -1.2

z = (P - p) / SE = (0.51 - 0.48) / 0.025 = 1.2

Using a standard normal distribution table or calculator, we can find the area under the curve between these two z-values, which represents the probability that the sample proportion is within three percentage points of the population proportion:

P(-1.2 < z < 1.2) = 0.7372

To find the probability that the sample proportion is within six percentage points of the population proportion, or between 0.42 and 0.54, we can use the same approach:

z = (P - p) / SE = (0.42 - 0.48) / 0.025 = -2.4

z = (P - p) / SE = (0.54 - 0.48) / 0.025 = 2.4

Again, using a standard normal distribution table or calculator, we can find the area under the curve between these two z-values:

P(-2.4 < z < 2.4) = 0.9772

If The total revenue earned (in dollars) from selling the books is given by the function R-34.60N. the equation relating P to N is P = 18.95N - 750.

Profit made (P) can be calculated by subtracting the total production cost (C) from the total revenue earned (R), so:

P = R - C

P = 34.60N - (18.95N + 750)

P = 34.60N - 18.95N - 750

P = 15.65N - 750

Therefore, the equation relating P to N is P = 18.95N - 750.

The equation shows that the profit made by the company is a linear function of the number of books printed. The slope of the line is the revenue per book (34.60 dollars), minus the cost per book (18.95 dollars), which is 18.95 dollars.

The intercept of the line is the fixed cost for editing (750 dollars). The equation can be used to estimate the profit for any given number of books printed, and to determine the break-even point, which is the number of books that need to be sold to cover the total production cost.

Answer:

Step-by-step explanation:

Option B, 18 million, is the answer to this question.

In September 1998, the population of West Goma in millions was modeled by the function f(x) = 17.9e0.002x, and the population of East Goma in millions was modeled by the function g(x) = 13.6e0.017x. Here, x represents the year, with x=0 corresponding to September 1998.

To find out the point of intersection where the populations are equal, we equate both formulas and solve for x:

17.9e0.002x = 13.6e0.017x

Taking the natural logarithm of both sides of the equation gives:

x ln(17.9) + 0.002x = x ln(13.6) + 0.017x

Simplifying and rearranging terms, we get:

ln(17.9) - ln(13.6) = (0.017 - 0.002)x

0.079 = 0.015x

Solving for x, we get:

x = 5.27 years

Since x is the year, when x = 5.27, it corresponds to the year 1998 + 5.27 ≈ 2003.

When the populations are equal, the population will be f(5.27) ≈ 18 million for West Goma.

The given paths of the receiver and defensive player can be described parametrically, using the parameter t, as:

Receiver: x = 5, y = 50 - 10t

Defensive: x = 10 - 0.9t, y = 54 - 10.72t

We can use the parameter t to represent the time that has elapsed since they started moving. The parametric equations describe the x and y coordinates of each player as functions of t.

By plugging in different values of t, we can determine the positions of the players at different points in time. In this case, the receiver moves horizontally while the defensive player moves at an angle, so their equations are different.

After the 15% increase in her hourly rate, Carmen's new hourly rate will be $18.40 per hour.

Carmen currently makes $480 in a month by working 30 hours. To find her hourly rate, we can divide her total earnings by the number of hours she worked:

Hourly rate = Total earnings ÷ Number of hours worked

So Carmen's current hourly rate is:

Hourly rate = $480 ÷ 30 = $16 per hour

If Carmen gets a 15% increase in her hourly rate, we can calculate her new hourly rate by multiplying her current hourly rate by 1.15 (since a 15% increase means the new rate is 115% of the current rate):

New hourly rate = Current hourly rate x 1.15

New hourly rate = $16 x 1.15

New hourly rate = $18.40 per hour

This means she will earn $2.40 more per hour than she did before the increase.
