Find the solution to -2/9=4/m.

Option D (9) is not a probability and is not a possible answer choice for a probability question.

To find the probability of the intersection of events A and B (denoted as P(A ∩ B)), we need to know how many elements are in both A and B. Since there are 2 repeated elements between the events, this means that there are a total of 7 - 2 = 5 distinct elements between them.

Therefore, P(A ∩ B) = 5/7.

Note that none of the answer choices provided match this result exactly. Option A is the closest with a probability of 4/7, but this is the probability of A alone, not the intersection of A and B. Option B (2/7) is the probability of B alone and option C (5/7) is the probability of either A or B occurring, not the intersection.

76.62 to 88.66

A manager records the repair cost for 4 randomly selected stereos. A sample mean of $82.64 and standard deviation of $14.32 are subsequently computed.

The 90% confidence interval for the mean repair cost for the stereos is 76.62 to 88.66. The population is assumed to be approximately normal. The given data are: Sample mean, x¯= $82.64 Standard deviation, s = $14.32.

The sample size, n = 4. For a given confidence level, the interval within which the population mean lies is known as the confidence interval.

To find the 90% confidence interval for the mean repair cost for the stereos, we use the formula below: Lower limit= x¯ - z (σ / √n)Upper limit= x¯ + z (σ / √n)Here, z is the z-score associated with a 90% confidence level. We can get this value from the standard normal distribution table.

At a 90% confidence level, the z-score is 1.645. Lower limit= 82.64 - 1.645 (14.32 / √4)= $76.62. Upper limit= 82.64 + 1.645 (14.32 / √4)= $88.66.

Therefore, the 90% confidence interval for the mean repair cost for the stereos is 76.62 to 88.66.

Answer:

Step-by-step explanation:

The missing step is the factorization of the quadratic

(x+3)(x+2)  

The coefficient for the interval -T ≤ x ≤ 0 in the function g(x) is 1. However, the coefficient for the interval 0 ≤ x ≤ 2π depends on the specific form of the function f(x). Without additional information about f(x), we cannot determine its coefficient for that interval.

To solve for the coefficients in the function g(x), we need to consider the conditions given:

g(x) = { 1, -1, -T ≤ x ≤ 0

{ 1, f(x + 2π) = g(x)

We have two pieces to the function g(x), one for the interval -T ≤ x ≤ 0 and another for the interval 0 ≤ x ≤ 2π.

For the interval -T ≤ x ≤ 0, we are given that g(x) = 1, so the coefficient for this interval is 1.

For the interval 0 ≤ x ≤ 2π, we are given that f(x + 2π) = g(x). This means that the function g(x) is equal to the function f(x) shifted by 2π. Since f(x) is not specified, we cannot determine the coefficient for this interval without additional information about f(x).

The coefficient for the interval -T ≤ x ≤ 0 is 1, but the coefficient for the interval 0 ≤ x ≤ 2π depends on the specific form of the function f(x).

The probability of graduating, given the student is female, is 70%. And The probability of being a female student who will graduate is 59.5%.

a. The probability that a randomly selected female student will graduate is 70% or 0.70.

b. The probability that a randomly selected student is female and will graduate is calculated by multiplying the probabilities of each event. Assuming independence, the probability is 0.85 (female) multiplied by 0.70 (graduate), resulting in 0.595 or 59.5%.

c. The two probabilities are different because the first probability (a) considers all female students, including those who may not graduate, while the second probability (b) focuses on the intersection of female students and those who will graduate. Therefore, the second probability is a subset of the first, leading to a lower probability.

Therefore, the probability that the student attends class on a certain Friday is 1/2, and the probability that the student is absent is also 1/2. The long-run probability that the student either attends class or does not attend class is simply 1, since these are the only two possible outcomes.

Let's use A to represent the event that the student attends class on a certain Friday, and let's use B to represent the event that the student is absent on a certain Friday. We are asked to find the long-run probability that the student either attends class or does not attend class.

We can use the law of total probability and consider the two possible scenarios:

Scenario 1: The student attends class on a certain Friday

If the student attends class on a certain Friday, then the probability that she will attend class the next Friday is 1/3, and the probability that she will be absent is 2/3. Therefore, the probability that the student attends class on two consecutive Fridays is:

P(A) * P(A|A) = P(A) * 1/3

Scenario 2: The student is absent on a certain Friday

If the student is absent on a certain Friday, then the probability that she will attend class the next Friday is 4/5, and the probability that she will be absent again is 1/5. Therefore, the probability that the student is absent on two consecutive Fridays is:

P(B) * P(A|B) = P(B) * 4/5

The probability that the student attends class or is absent on a certain Friday is 1, so we have:

P(A) + P(B) = 1

Now we can solve for P(A) and P(B) using the system of equations:

P(A) * 1/3 + P(B) * 4/5 = P(A) + P(B)

P(A) + P(B) = 1

Simplifying the first equation, we get:

2/3 * P(B) = 2/3 * P(A)

P(B) = P(A)

Substituting into the second equation, we get:

2 * P(A) = 1

P(A) = 1/2

The cash ratio is 0.80, or 0.80:1, which means that the company has $0.80 in cash and cash equivalents for every $1 of current liabilities that it owes.

The cash ratio is a financial ratio that measures the ability of a company to pay off its current liabilities using only its cash and cash equivalents.

The formula for the cash ratio is:

Cash Ratio = (Cash and Cash Equivalents) / (Total Current Liabilities)

Using the information given in the question:

Cash and cash equivalents = $60,000

Total current liabilities = $75,000

Plugging these values into the formula:

Cash Ratio = $60,000 / $75,000 = 0.80

Therefore, the cash ratio is 0.80, or 0.80:1, which means that the company has $0.80 in cash and cash equivalents for every $1 of current liabilities that it owes.

The table and the given points on the coordinate plane provide information about the relationship between the number of hours of

pet-sitting (x) and the amount of money earned (y) by Melissa, who charges a fixed rate of $1.25 per hour for pet-sitting.

The equation of the line passing through the points (1, 1.25) and (4, 5) can be found by using the slope-intercept form:

y - y_1 = m (x - x_1),

where m is the slope and (x_1, y_1) is a point on the line.

Using the two given points, we have:

m = (y_2 - y_1)/(x_2 - x_1)
