Answer:

4 miss days per year

Step-by-step explanation:

Let the previous employees miss days be = x

As given, miss days now are 75% less than previous

x - 75%x = 1/365

0.25x = 1/365

x = 1 / (365 x 0.25)

x = 4/365

So, average back then could have been 4 days per 365 days

The function g(x) is a transformation of the cube root parent function f(x) = ∛x will be g(x) = ∛(x - 4) - 3. Then the correct option is D.

A statement, principle, or policy that creates the link between two variables is known as a function.

The function g(x) is a transformation of the cube root parent function that will be given below.

f(x) = ∛x.

If we subtract h in the variable of the function then the function shifts toward the left by h units.

And if we subtract k in the function then the function shifts downward by k units.

Then the function g(x) will be

g(x) = ∛(x - 4) - 3

Then the correct option is D.

The value of (gor)(1) is 0, indicating that the composition of the functions g and r, evaluated at x = 1, results in an output of 0. Similarly, the value of (rog)(1) is also 0, indicating that the composition of the functions r and g, evaluated at x = 1, also gives an output of 0.

The composition of two functions, denoted as (fog)(x), is obtained by substituting the output of the function g into the input of the function f. In this case, we have two functions q(x) = -4x + 1 and r(x) = 3x - 2. To evaluate (gor)(1), we first evaluate the inner composition (or the composition of g and r) by substituting x = 1 into r(x). This gives us r(1) = 3(1) - 2 = 1. Next, we substitute this result into q(x), obtaining q(r(1)) = q(1) = -4(1) + 1 = -3. Therefore, (gor)(1) = -3.

Similarly, to evaluate (rog)(1), we first evaluate the inner composition (or the composition of r and g) by substituting x = 1 into g(x). This gives us g(1) = -4(1) + 1 = -3. Next, we substitute this result into r(x), obtaining r(g(1)) = r(-3) = 3(-3) - 2 = -11. Therefore, (rog)(1) = -11.

Since the given task asks to find when the compositions of the functions are equal to 0, neither (gor)(1) nor (rog)(1) is equal to 0.

Thus, the probability that two people picked at random both own a dog is 0.1296 or 1296/10000.

To solve this problem, we need to use the formula for calculating the probability of independent events: P(A and B) = P(A) x P(B).

In this case, let A be the event that the first person owns a dog and B be the event that the second person owns a dog.

We know that P(A) = 0.36, or 36% chance that the first person owns a dog. Since the events are independent, P(B) is also 0.36.

So, the probability of both events occurring (both people owning dogs) is:

P(A and B) = P(A) x P(B)
= 0.36 x 0.36
= 0.1296

This can also be expressed as a fraction:

P(A and B) = 36/100 x 36/100
= 1296/10000

Therefore, the probability that two people picked at random both own a dog is 0.1296 or 1296/10000.

The numbers that cannot be probabilities are: square root of 2, -53, 5/3, and 1.31.

Probability is a measure of the likelihood of a particular event occurring in a random experiment. It is a value between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

In statistics, probability is used to make predictions or draw inferences about a population based on a sample of data. For example, if we were to flip a coin, the probability of getting heads is 0.5, or 50%. In general probability can be defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, which is the mathematical framework behind the random experiments.

From the set of numbers, 0, 0.08, and 3/5 are all possible values of probability.

Therefore, square root of 2, -53, 5/3, and 1.31 cannot be probabilities.

We get the squares of the number as 1 , 4 , 9 , 16.......as given below, hence we get square of any number by product with itself.

The outcome of multiplying an integer by itself is referred to as the resultant number's square. In essence, a square number is a result of multiplying two identical numbers. The best illustration of a square number in geometry is the area of a square with side lengths of "n" (where n is an integer).

As an illustration, (-7)² = -7 -7 = 49 (two negative signs multiplied by each other result in a positive sign). The value of multiplying -7 and -7 is 49, which is a positive square number.

a. The equilibrium interest rate,  is determined by the risk-free interest rate, the probability of repayment, and the cost of default.

b. The probability of the government repaying its loan can be calculated using the loan repayment threshold and the distribution of the output.

c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default.

a. To find the equilibrium interest rate,  we need to consider the risk-free interest rate, the probability of repayment, and the cost of default. The equilibrium interest rate is given by the formula: r = r + (c/p), where r is the risk-free interest rate, c is the cost of default, and p is the probability of repayment.

b. The probability that the government will repay its loan can be calculated by determining the percentage of the output distribution that exceeds the loan repayment threshold. Since 0.5 of the output is required to repay the loan, we need to calculate the probability that the output exceeds L/0.5.

c. If the interest rate, r, is equal to or greater than the equilibrium interest rate, the borrowing country would default. This can be proven by comparing the repayment threshold (L/0.5) with the loan repayment amount (L + Lr). If the repayment threshold is greater than the loan repayment amount, the borrowing country would default.

So, Lana gave away 26.32% of he Pokemon cards  to her little brother.

To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.

In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:

(125 / 475) * 100 = 0.2632 * 100 = 26.32%.

Lana gave away 26.32% of her Pokemon cards to her little brother.

Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:

Percentage given away

= (Cards given away / Total cards) * 100

In (a) the probability that a student is both a sophomore and a history major is 38/63, and (b) the probability that a history major is also a sophomore is 38/30.

(a) To find the probability that a student is both a sophomore and a history major, we need to determine the number of students who satisfy both conditions and divide it by the total number of students in the class. Since 7 students are neither sophomores nor history majors, we subtract this number from the total number of students: 63 - 7 = 56. Out of the 56 remaining students, we know that 38 are sophomores and 30 are history majors. The probability that a student is both a sophomore and a history major is given by the ratio of the number of students satisfying both conditions (intersection) to the total number of students: 38/63.

(b) Given that the student selected is a history major, we are only considering the students who are history majors, which is a total of 30. We need to find the probability that a history major is also a sophomore. To do this, we need to determine the number of history majors who are sophomores and divide it by the total number of history majors: 38/30.

To calculate the present value of a zero-coupon bond, we can use the formula: Present Value = Future Value / (1 + Interest Rate)^n

where Future Value is the par value of the bond, Interest Rate is the annual market interest rate, and n is the number of years. In this case, the Future Value is $2,000, the Interest Rate is 10% (or 0.10), and the number of years is 5. Using Excel, we can calculate the present value as follows:
1. In cell A1, enter the Future Value: 2000
2. In cell A2, enter the Interest Rate: 0.10
3. In cell A3, enter the number of years: 5
4. In cell A4, enter the formula for calculating the present value: =A1 / (1 + A2)^A3
5. Press Enter to get the result.

The present value of the 5-year zero-coupon bond with a $2,000 par value and an annual market interest rate of 10% is $1,620.97.

The formula for present value calculates the current worth of a future amount by discounting it back to the present using the interest rate. In this case, the future value is $2,000, and we divide it by (1 + 0.10)^5 to account for the effect of compounding over 5 years. The result is the present value of $1,620.97, which represents the amount that is considered equivalent to receiving $2,000 in 5 years at a 10% interest rate.
