Mr.Green washed the most laundry with .375 of it done

what remains is .291

Step-by-step explanation:

3/8 or 3 divided by 8 is .375

Answer:

1. Mr. Green washed more laundry 2. 7/24 of the laundry still needs to be washed

Step-by-step explanation:

If you find a common denominator you can compare them. I used the common denomiator of 24. Next, you need to change both fractions so that they have the same denominator. To do that we have to multiply both the numerator and denominator of 3/8 by 3. When you do that, you end up with 9/24. Then you have to do the same for 1/3 but this time multiplying the numerator and the denominator by 8. That will leave us with 9/24 and 8/24 which proves that Mr. Green did more laundry.

For the second question, we will need to add the two amounts of laundry already washed and then find out how much remains from there. We can use the fractions that already have a common denominator from the explanation above. Now we have to add 9/24 and 8/24 together. Once we add them together, we will get 17/24 which is how much laundry is already done. Now, we need to take the remaining amount from 17/24 which is 7/24, and that represents how much laundry sitll needs to be washed.

The number of ways the cricket club can assign 11 of its 14 members to the 11 distinct positions on the cricket field is 8,008,840, using the concept of combinations.

In the explanation, we'll provide a step-by-step calculation using the concept of combinations.

To summarize the answer, there are 8,008,840 possible ways to assign 11 members to the 11 positions.

To explain the calculation, we'll use the concept of combinations. In this scenario, we need to select 11 members out of 14 without regard to their order or position. Since the order doesn't matter, we use combinations rather than permutations.

The formula for combinations is given by C(n, r) = n! / (r! * (n - r)!), where n is the total number of members (14) and r is the number of members to be selected (11).

Using this formula, we can calculate the number of ways to assign 11 members to the 11 positions as follows:

C(14, 11) = 14! / (11! * (14 - 11)!)

         = 14! / (11! * 3!)

         = (14 * 13 * 12 * 11!) / (11! * 3 * 2 * 1)

         = (14 * 13 * 12) / (3 * 2 * 1)

         = 2184

Therefore, there are 2,184 possible ways to assign 11 members to the 11 positions on the cricket field.

L = k/f, where k is the variational constant, is the formula for the inverse variation.

A mathematical relationship between two variables in which they vary in opposing directions is referred to as an inverse proportion, also known as an inverse relationship. When one variable increases while the other decreases, this is known as having inverse proportions.

Using the variables length of violin 'l' and frequency of vibration 'f'

If the length of violin 'l' is inversely proportional to the frequency of vibration 'f', this is expressed as:

l α 1/f

l = k/f

The distance between the two points in a radical form is √85 units

From the question, we have the following coordinate points that can be used in our computation:

(-8,-4),(1,-6)

The distance between the points is calculated as

distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where

(x, y) = (-8,-4),(1,-6)

Substitute the known values in the above equation, so, we have the following representation

distance = √[(1 + 8)² + (-6 + 4)²]

Evaluate

distance = √85

The probability of event A given that event B has occurred is equal to the probability of event A, which is 0.7.

If A and B are independent events, then the occurrence of event B does not affect the probability of event A. Therefore, we can use the formula for conditional probability, P(A|B) = P(A ∩ B) / P(B), to calculate the probability of event A given that event B has occurred.

However, since A and B are independent, we know that P(A ∩ B) = P(A) x P(B), which gives us:

P(A | B) = P(A ∩ B) / P(B) = (P(A) x P(B)) / P(B) = P(A) = 0.7

This makes sense because the independence of A and B implies that knowing the outcome of event B does not provide any additional information about the probability of event A.

Answer:

3 hours and 24 minutes

Step-by-step explanation:

Each our is 60 minutes long, so we have to times 60 by x until we get to 204, or close to it.

The closest we can get to 204 is 180, which is 60 times 3, hence the 3 hours.

Now we have to do 204-180, which is 24.

So the movies is 3 hours and 24 minutes long.

Hope this helps!

Answer:

Step-by-step explanation:

Recall that 60 min = 1 hr.

First divide 204 min by (60 min / 1 hr):

  204 min

----------------- = 3.4 hr

60 min/1 hr

Break this up further:  3.4 hr = 3 hr plus 0.4 hr

                                                = 3 hr plus 0.4 hr (60 min / 1hr)

                                                 = 3 hr plus 24 min

One car travel South at 64 mi/h and the other travels west at 48 mi/h. The distance between the cars increases with rate at 80 mi/h.

To find the rate of change, we need to find the derivative of the variables with respect to time.

Let:

p = distance between 2 cars

q = distance between car 1 and the start point

r = distance between car 2 and the start point

Using the Pythagorean Theorem:

p² = q² + r²

Take the derivative with respect to time:

2p dp/dt = 2q dq/dt + 2r dr/dt

dq/dt = speed of car 1 = 64 mi/h

dr/dt = speed of car 2 = 48 mi/h

The distance of car 1 and car 2 from the start point after 4 hours:

q = 64 x 4 = 256 miles

r = 48 x 4 = 192 miles

Using the Pythagorean theorem:

p² =256² + 192²

p = 320 miles

Hence,

2p dp/dt = 2q dq/dt + 2r dr/dt

p dp/dt = q dq/dt + r dr/dt

320  x dp/dt = 256 x 64 + 192  x 48

dp/dt = 80

Given the cumulative distribution function (CDF) f(x) = x^2 on the interval [0, 1], we need to find the probability P(0.7 ≤ x ≤ 1). The probability that x lies between 0.7 and 1 with the given CDF is 0.51.

To do this, we'll use the CDF to calculate the probabilities at the given bounds and then subtract the lower bound probability from the upper bound probability.
For the upper bound (x = 1), the CDF value is:
f(1) = 1^2 = 1
For the lower bound (x = 0.7), the CDF value is:
f(0.7) = (0.7)^2 = 0.49
Now, subtract the lower bound probability from the upper bound probability to find the probability in the given interval:
P(0.7 ≤ x ≤ 1) = f(1) - f(0.7) = 1 - 0.49 = 0.51

The derivative of F(x) is \(F'(x) = x^{(1/3)\).

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.

Let's compute F'(x):

F(x) = ∫[0 to x] \(t^{(1/3)} dt\)

To differentiate the integral with respect to x, we'll use the Leibniz integral rule:

F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)

According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.

\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\)   [applying the chain rule to the upper limit]

Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.

\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)

\(F'(x) = x^{(1/3)\)

Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

Therefore, the integral ∫ (3cos(8x) - 2sin(4x) + 2sec(tan(x))) dx cannot be expressed in terms of elementary functions.

To evaluate the integral ∫ (3cos(8x) - 2sin(4x) + 2sec(tan(x))) dx, we can simplify each term and then integrate term by term.

Let's start by simplifying each term:

∫ 3cos(8x) dx - ∫ 2sin(4x) dx + ∫ 2sec(tan(x)) dx

To integrate each term, we can use standard integration formulas:

∫ cos(ax) dx = (1/a) sin(ax) + C

∫ sin(ax) dx = -(1/a) cos(ax) + C

∫ sec²(u) du = tan(u) + C

Applying these formulas, we have:

(3/8) ∫ cos(8x) dx - (2/4) ∫ sin(4x) dx + 2 ∫ sec(tan(x)) dx

= (3/8) (1/8) sin(8x) - (1/2) (-1/4) cos(4x) + 2 ∫ sec(tan(x)) dx

= (3/64) sin(8x) + (1/8) cos(4x) + 2 ∫ sec(tan(x)) dx

Now, we need to evaluate the integral of sec(tan(x)) dx. This integral does not have a simple closed-form expression, so we cannot integrate it directly. It is often denoted as "non-elementary" or "special" integral.

The steps of the analytical problem-solving model include: identifying the problem, exploring alternatives, building an implementation plan, implementing a solution, and evaluating the situation.

Analytical problem solving, as we've defined it above, refers to the approaches and methods you use rather than the particular issue you're trying to resolve.

Analytical issue solving is a crucial prerequisite for problem resolution; the problem itself does not determine whether you need it.

Analytical problem solving involves recognising a problem, investigating it, and then creating ideas (such as causes and solutions) around it.
