Answer:

$ 23.75

Step-by-step explanation:

Discount = 75% of 95

               = \(\frac{75}{100}*95\)

               = 0.75 * 95

              = $ 71.25

Amount to be paid after discount = 95 - 71.25

                                                       = $ 23.75

Step-by-step explanation:

Average waiting time for FCFS: 8.75

Average waiting time for SJF: 4.75

To solve this scheduling problem using FCFS (First-Come, First-Served) and SJF (Shortest Job First) algorithms, let's go step by step:

Schedule order for FCFS:

The FCFS algorithm schedules processes based on their arrival time. So, the schedule order for FCFS is as follows:

Pl -> P2 -> P3 -> P4

Average waiting time for FCFS:

To compute the average waiting time for FCFS, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P2 | 3 | 10 | 3

P3 | 4 | 6 | 13

P4 | 5 | 1 | 19

Average waiting time = (0 + 3 + 13 + 19) / 4 = 8.75

Therefore, the average waiting time for FCFS is 8.75.

Schedule order for SJF:

The SJF algorithm schedules processes based on their running time. The process with the shortest running time gets executed first. If multiple processes have the same running time, the process with the earliest arrival time is selected first. The schedule order for SJF is as follows:

Pl -> P4 -> P3 -> P2

Average waiting time for SJF:

To compute the average waiting time for SJF, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P4 | 5 | 1 | 3

P3 | 4 | 6 | 6

P2 | 3 | 10 | 10

Average waiting time = (0 + 3 + 6 + 10) / 4 = 4.75

Therefore, the average waiting time for SJF is 4.75.

The cutoffs for the middle 90 percent of a normal distribution with a mean of 0.600 and a standard deviation of 0.056 are 0.395 and 0.805.

To find the cutoffs for the middle 90 percent of a normal distribution, we need to determine the values that correspond to the 5th and 95th percentiles.

Since the distribution is normal with a mean of 0.600 and a standard deviation of 0.056, we can use statistical tables or a calculator to find these values.

Finding the lower cutoff:

The 5th percentile corresponds to the value below which 5% of the data lies. Using the mean and standard deviation, we can find this value.

Subtracting 1.645 (the z-score corresponding to the 5th percentile) multiplied by the standard deviation from the mean, we get:

\(Lower\ cutoff = 0.600 - (1.645 * 0.056) = 0.395 (rounded\ to\ 3\ decimal\ places)\)

Finding the upper cutoff:

The 95th percentile corresponds to the value below which 95% of the data lies.

Adding 1.645 (the z-score corresponding to the 95th percentile) multiplied by the standard deviation to the mean, we get:

\(Upper\ cutoff = 0.600 + (1.645 * 0.056) = 0.805 (rounded\ to\ 3\ decimal\ places)\)

Therefore, the cutoffs for the middle 90 percent of the normal distribution with a mean of 0.600 and a standard deviation of 0.056 are approximately 0.395 and 0.805.

Answer:

No

Step-by-step explanation:

Prime numbers have to be only divisible by one and themselves (2 numbers), but one is,\(1*1\) so it is only divisible by one number, thus it is not prime.

Answer:

B and C

Step-by-step explanation:

Both B and C

B)

2/5 = 0.4 (which terminate as decimals)

Similarly

C)

-1/4 = -0.25 (also terminates)

But A and D do not terminate

As for A) 1/3= 0.33333333..........

and for D) 7/9= 0.777777777......

In both cases the decimals are a never ending sequence or in other words does not terminate at all. They are irrational numbers.

Answer:

y = \(\frac{3}{2}\) x

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = \(\frac{3}{2}\) and y- intercept c = 0 , then

y = \(\frac{3}{2}\) x + 0 , that is

y = \(\frac{3}{2}\) x

The marginal propensity to consume (MPC) for Australia in 2021, when total income (Y) is 10, is 0.3.

The consumption function for Australia in 2021 is given as C = 0.0052 + 0.3Y + 20, where C represents the total consumption and Y represents the total income. To calculate the MPC, we need to determine how much of an increase in income is consumed rather than saved. In this case, when Y = 10, we substitute the value into the consumption function:

C = 0.0052 + 0.3(10) + 20

C = 0.0052 + 3 + 20

C = 23.0052

Next, we calculate the consumption when income increases by a small amount, let's say ΔY. So, when Y increases to Y + ΔY, the consumption function becomes:

C' = 0.0052 + 0.3(Y + ΔY) + 20

C' = 0.0052 + 0.3Y + 0.3ΔY + 20

To find the MPC, we subtract the initial consumption (C) from the new consumption (C') and divide it by the change in income (ΔY):

MPC = (C' - C) / ΔY

MPC = (0.0052 + 0.3Y + 0.3ΔY + 20 - 23.0052) / ΔY

Simplifying the equation, we can cancel out the terms that don't involve ΔY:

MPC = (0.3ΔY) / ΔY

MPC = 0.3

Step-by-step explanation:

For f(1) = 0 the statement is true that (x - 1) is the factor of the function.

Polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given a function,

f(x) = x⁶ - x⁴ + 2x² - 2

and f(1) = 0

substitute the values,

f(x) = x⁶ - x⁴ + 2x² - 2

f(1) = 1⁶ - 1⁴ + 2(1)² - 2

f(1) = 0

so when x = 1 function is zero,

so x - 1 = 0 and (x - 1) is one of the factor of function f(x).

Hence the statement is true.

Step-by-step explanation:

Rate : 10 dollars a week

You will have saved up $4,680 in 9 years.

To approximate the area under the curve of the function f(x) = 2 + 2 over the interval [2, 8] using three rectangles with right endpoints, we need to follow the following steps:

Determine the width of each rectangle: Δx = (b-a)/n, where b is the upper bound of the interval, a is the lower bound of the interval, and n is the number of rectangles. In this case, b = 8, a = 2, and n = 3, so Δx = (8-2)/3 = 2.

Determine the height of each rectangle: We will use the right endpoint method, which means that the height of each rectangle will be equal to the value of the function at the right endpoint of each subinterval. In this case, the right endpoints of the subintervals are x = 4, 6, and 8, so the heights of the rectangles will be f(4), f(6), and f(8), respectively. Evaluating the function at these points, we get:

f(4) = 2 + 2 = 4

f(6) = 2 + 2 = 4

f(8) = 2 + 2 = 4

Calculate the area of each rectangle: A = base x height. Since the width of each rectangle is 2 (as we calculated in step 1), the area of each rectangle will be:

A1 = 2 x 4 = 8

A2 = 2 x 4 = 8

A3 = 2 x 4 = 8

Add up the areas of all the rectangles to get an approximation of the total area under the curve:

Approximate area = A1 + A2 + A3 = 8 + 8 + 8 = 24

Therefore, the approximate area under the curve of the function f(x) = 2 + 2 over the interval [2, 8] using three rectangles with right endpoints is 24 square units.

B)  A dilation with a center of dilation at the origin, followed by a translation down and a translation to the left.

The graph's curve "moves to the left/right/up/down," "it expands or compresses," or "it reflects" when a function is transformed. For instance, simply advancing the graph of the function g(x) = x2 by 3 units will yield the graph of f(x) = x2 + 3. Function transformations are very useful for graphing the functions by simply moving, expanding, compressing, or reflecting the curve, as opposed to having to start from scratch with the graphing.

A function transformation "moves," "resizes," or "reflects" the parent function's graph, depending on the case. Function transformations can be broadly divided into three categories:
