Since the calculated F-value of 7.098 is greater than the critical value of 5.79, we reject the null hypothesis and conclude that the population variance of total sales during active price competition is higher than during duopoly and tacit collusion at the 5% level of significance.

For the above issue, the null and alternate hypotheses are as follows:

The population variations of total sales under duopoly, active price competition, and tacit cooperation are all identical.

In contrast to duopoly and implicit collusion, total sales population variance is larger under active price competition.

To test the null  hypothesis, we must use a two-tailed F- test with a 5 % threshold of significance. The ratio of the sample variances is used to determine the F- statistic.

F = s1² / s2²

Where:
s1² - Sample Variance (Active price competition)

s2² -  SAmple variance (Duopoy and Tacit collusion)


Since n1-1 = 3
and n2-1 = 6

F = 114.09 / 16.08
F = 7.098

Having derived same, we know that the critical values of F for a two-tailed test with 3 and 6 degrees of freedom at 5% level of significance are:

Critical Value (3) = 5.14
Critical Value (6) = 5.79

Therefore, since the F-value > Critical Value in both cases, we must reject the null hypothesis.

Step-by-step explanation:

The formula for computing accrued amount(principal + interest) is given by

[tex]A = P\left (1 + \dfrac{r}{n}\right )^{nt}[/tex]

where

P =principal amount
r = annual interest rate as a decimal
n = number of times compounded per year
t = number of years
A = amount accrued at the end of t years

We are given
A = 62702.95
P = 4000
n = 4 since we are compounding quarterly, i.e. 4 times a year
t = 20

Plugging in known values into the equation we get
[tex]62702.95 = 4000\left(1 +\dfrac{r}{4}\right)^{4 \cdot 20}\\\\62702.95 = 4000\left(1 +\dfrac{r}{4}\right)^{80}\\\\[/tex]

The answer is 8.54

If P(A) is 0.64, then P(A') is 0.36. P(A) is probability of occurrence of event A.

This question pertains to Probability principles. Probability is a measure of the possibility of an event occurring. Many occurrences cannot be foreseen with absolute accuracy. We can only anticipate the likelihood of an event occurring using it.

A is an occurrence in this context. A' denotes the event's complement.  

For example, if Event A is getting heads on a coin toss, then Event A' is getting tails.

This demonstrates one thing:

A ∪ A' = U, here U is the universal set.

P ( U) = 1

P (A) + P(A') = 1

0.64 + P (A') = 1

P(A') = 1 - 0.64

Step-by-step explanation:

To calculate Michelle’s monthly credit card payment, we need to find the total amount she owes and then divide it by the number of months she has to pay it off.

First, we need to find the total balance on Michelle’s credit cards:

$4,380 + $1,365 + $2,480 + $5,000 = $13,225

Next, we need to find the weighted average interest rate of her credit cards. To do this, we multiply each balance by its corresponding APR and add up the results. Then we divide by the total balance:

($4,380 x 0.17) + ($1,365 x 0.19) + ($2,480 x 0.23) + ($5,000 x 0.15) = $1,038.55

$1,038.55 ÷ $13,225 = 0.0785, or 7.85%

Now we can use the total balance and the weighted average interest rate to calculate Michelle’s monthly payment using the formula for a fixed payment on a loan:

P = (r(PV)) / (1 - (1 + r)^-n)

Where:

P = monthly payment

r = monthly interest rate (as a decimal)

PV = present value of the loan

n = number of payments

r = 0.16 ÷ 12 = 0.01333 (monthly interest rate)

PV = $13,225

n = 36

P = (0.01333(13,225)) / (1 - (1 + 0.01333)^-36) = $367.36

Therefore, Michelle’s monthly credit card payment would be $367.36 if she consolidated all of her credit card debt into a single credit card with an interest rate of 16% and paid it off in 36 months. The answer is (a) $367.36.

The radian measure that is equivalent to 300° is equal to 5π/3. So, correct option is D.

To convert degrees to radians, we use the conversion factor of π/180, which means that one degree is equal to π/180 radians. Therefore, to convert 300° to radians, we multiply 300 by π/180:

300° * π/180 = 5π/3

To understand this conversion, we need to remember that radians are a unit of measurement for angles, just like degrees. However, while degrees divide a circle into 360 equal parts, radians divide a circle into 2π equal parts. One full rotation is equal to 2π radians, which is also equal to 360°.

Since 5π/3 radians is less than one full rotation, it represents an angle that is less than 360°. In fact, 5π/3 radians is equivalent to 300°, which is a well-known angle used in many contexts, such as in geometry, trigonometry, and physics.

In summary, to convert 300° to radians, we multiply it by the conversion factor π/180, which gives us the equivalent angle measure of 5π/3 radians.

So, correct option is D.

Answer: The area of the floor of the hall is approximately 599.2448 square meters.

Step-by-step explanation: Let's assume the breadth of the hall be x meters. Then, the length of the hall will be 2x meters and the height will be 3x meters.

The volume of the hall can be found as follows:

Volume = Length × Breadth × Height

36000 = 2x × x × 3x

36000 = 6x³

x³ = 6000

x = ∛6000 ≈ 17.32 meters

Therefore, the breadth is approximately 17.32 meters, the length is 2 × 17.32 = 34.64 meters, and the height is 3 × 17.32 = 51.96 meters.

The area of the floor can be found by multiplying the length and breadth:

Area = Length × Breadth

Area = 34.64 × 17.32

Area = 599.2448 m²

Therefore, the area of the floor of the hall is approximately 599.2448 square meters.

Step-by-step explanation:

We know that the vertex of the parabola is at the origin, so the equation must have the form:

y = a x^2

where a is a constant.

We also know that the directrix is y = -1.5, which means that the focus is located at (0, 1.5).

Using the formula for the distance between a point (x, y) and a line ax + by + c = 0, which is given by:

d = |ax + by + c| / sqrt(a^2 + b^2)

we can find the value of a. The distance from the vertex (0, 0) to the directrix y = -1.5 is equal to the distance from the vertex to the focus (0, 1.5), so we have:

d = |y - (-1.5)| / sqrt(1^2 + 0^2) = sqrt(x^2 + (y - 1.5)^2) / sqrt(0^2 + 1^2)

Simplifying this equation, we get:

sqrt(x^2 + (y - 1.5)^2) = |y + 1.5|

Squaring both sides, we get:

x^2 + (y - 1.5)^2 = (y + 1.5)^2

Expanding and simplifying, we get:

x^2 = 3y

So the equation of the parabola with vertex at the origin and directrix y = -1.5 is:

y = (1/3)x^2

Therefore, the correct answer is: y = (1/3)x^2.
