If the probability that the Islanders will beat the Rangers in a game is 0.88, what is the probability that the Islanders will win at least three out of four games in a series against the Rangers? Round your answer to the nearest thousandth.

Answers

Answer 1
To calculate the probability that the Islanders will win at least three out of four games in a series against the Rangers, we need to consider all the possible combinations of games they could win.

The probability that the Islanders win exactly three games in the series is:

P(3 wins) = (4 choose 3) * (0.88)^3 * (0.12)^1 = 0.59205

where "4 choose 3" represents the number of ways to choose 3 games out of 4.

Similarly, the probability that the Islanders win all four games is:

P(4 wins) = (4 choose 4) * (0.88)^4 * (0.12)^0 = 0.59969568

Therefore, the probability that the Islanders win at least three out of four games in the series is the sum of the probabilities of winning exactly three games and winning all four games:

P(at least 3 wins) = P(3 wins) + P(4 wins) = 0.59205 + 0.59969568 = 1.19174568

However, probabilities cannot exceed 1, so we need to adjust for overcounting by subtracting the probability of winning all four games when we've already counted it as part of the probability of winning three games:

P(at least 3 wins) = P(3 wins) + P(4 wins) - P(4 wins | 3 wins)
where P(4 wins | 3 wins) is the conditional probability of winning all four games given that they've already won three games.

P(4 wins | 3 wins) = P(1 win out of 1 game) = 0.88

P(at least 3 wins) = P(3 wins) + P(4 wins) - P(4 wins | 3 wins)
= 0.59205 + 0.59969568 - 0.88
= 0.31174568

Therefore, the probability that the Islanders will win at least three out of four games in a series against the Rangers is approximately 0.312 to the nearest thousandth.

A:Kika; $300


B:Kika; $700


C:Mato; $700


D:Mato; $300

Answers

Mato will pay about $700 more in interest than Kika ($625 - $1,300 = $675, which rounds to $700). The answer is C: Mato; $700

Mato will pay more in interest because he has a higher interest rate and a shorter repayment period. To calculate the amount of interest each will pay, we can use the formula:

Interest = (Loan amount) x (Interest rate) x (Time in years)

For Kika:
Interest = $5,000 x 0.052 x 5
Interest = $1,300

For Mato:
Interest = $5,000 x 0.075 x (2/12)
Interest = $625

Therefore, Mato will pay about $700 more in interest than Kika ($625 - $1,300 = $675, which rounds to $700). The answer is C: Mato; $700.

Write the quadratic equation in standard form that represents the volume of the box:[tex]w^2 - 6w = 0[/tex]

Find the length, width, height  a box with volume of 6 [tex]ft^3[/tex], given the formula V = lwh.

Solve the quadratic equation for x and find the length and width of the box:

w(w - 6) = 0 (factor the quadratic)

w = 0 or w = 6 (apply the zero product property)

Since a box can't have a width of 0, we reject the solution w = 0.

So, the only solution is w = 6.

To find the length, we use the formula l = V/wh:

l = 6/(6h) = 1/h

The length depends on the value of h, but we can choose h = 1/6 ft to get a reasonable set of dimensions:

length = 1 ft

width = 6 ft

height = 1/6 ft

Therefore, the quadratic equation that represents the volume of the box is[tex]w^2 - 6w = 0[/tex], and the dimensions of the box are length = 1 ft, width = 6 ft, and height = 1/6 ft.

Answers

The area of glass value is 0.18 square meters.

The longer diagonal of the kite-shaped window has a measure of 25 cm + 35 cm = 60 cm.

The shorter diagonal has a measure of 30 cm + 30 cm = 60 cm as well.

To find the area of the window, we can use the formula -

Area = (1/2) × d1 × d2

Write an equation passing through the point and parallel to the given line.

Answers

The Equation of the line which is parallel to the line "y = 3x + 6", and also passes through (4,7) is "y = 3x - 5".

In order to find an equation of a line which passes through point (4,7) and is parallel to line "y = 3x + 6", we use the fact that parallel lines have the same slope.

The given line ""y = 3x + 6" has a slope of 3,

So, the "parallel-line" we want to find must also have a slope of 3.

Now, by using the "point-slope" form of the equation of a line, which is : y - y₁ = m(x - x₁),

where m is slope and (x₁, y₁) is a point on the line,

So, we substitute "m = 3" and (x₁, y₁) = (4,7) to get:

⇒ y - 7 = 3(x - 4),

⇒ y - 7 = 3x - 12,

⇒ y = 3x - 5

The mean of a continuous uniform distribution is simply the average of the upper and lower limits of the interval on which the distribution is defined. true or false

Answers

True. In a continuous uniform distribution, all values within a specified interval are equally likely to occur. The mean or expected value of this distribution can be found by taking the average of the upper and lower limits of the interval.

This can be represented mathematically as (a+b)/2, where a and b are the lower and upper limits of the interval. For example, if we have a continuous uniform distribution on the interval [0,10], the mean value would be (0+10)/2 = 5.

This means that on average, we would expect a randomly selected value from this distribution to be around 5. It's important to note that the mean of a continuous uniform distribution is not affected by the shape or spread of the distribution, as all values have an equal chance of occurring.

Let (x) = -x^4 -8x^3 +6x - 2. Find the open intervals on which is concave up (down). Then determine the x-coordinates of all inflection points a f.

Answers

The x-coordinates of all inflection points a f of the function[tex]f(x) = -x^4 - 8x^3 + 6x - 2[/tex]are (-4, f(-4)) and (0, f(0)).

To find the intervals of concavity and the inflection points of the function[tex]f(x) = -x^4 - 8x^3 + 6x - 2,[/tex] we need to find the second derivative and analyze its sign.

First, we find the first derivative:

[tex]f'(x) = -4x^3 - 24x^2 + 6[/tex]

Then, we find the second derivative:

[tex]f''(x) = -12x^2 - 48x[/tex]

To determine the intervals of concavity, we need to find where f''(x) is positive or negative.

[tex]f''(x) = -12x^2 - 48x = -12x(x + 4)[/tex]

f''(x) is negative for x < -4 and x > 0, and positive for -4 < x < 0.

Therefore, the function f(x) is concave down on the intervals (-∞, -4) and (0, ∞), and concave up on the interval (-4, 0).

To find the inflection points, we need to find where the concavity changes. This occurs at x = -4 and x = 0.

At x = -4, the function changes from concave down to concave up. Therefore, (-4, f(-4)) is an inflection point.

At x = 0, the function changes from concave up to concave down. Therefore, (0, f(0)) is also an inflection point.

Thus, the inflection points of f(x) are (-4, f(-4)) and (0, f(0)).

To calculate the probability of drawing a diamond or a spade card from a standard deck of cards, we need to find the total number of diamond and spade cards in the deck. There are 13 cards in each suit, so there are 26 diamond and spade cards in total. The deck has 52 cards in total, so the probability of drawing a diamond or a spade card is:

P(diamond or spade) = 26/52 = 1/2 = 50%

To calculate the probability of rolling a 2 on a six-sided die, we need to find the total number of possible outcomes, which is 6 (since there are 6 sides on the die), and the number of favorable outcomes, which is 1 (since there is only one face with a 2 on it). Therefore, the probability of rolling a 2 on a six-sided die is:

P(rolling a 2) = 1/6 = 16.67%

To find the probability of both events happening together (drawing a diamond or a spade card and rolling a 2 on a six-sided die), we multiply the probabilities of each event:

P(diamond or spade AND rolling a 2) = P(diamond or spade) * P(rolling a 2)

A circumscribed angle is an angle whose sides are to a circle

Answers

A circumscribed angle is an angle whose sides are tangent to a circle. In other words, the angle is formed by two intersecting chords of the circle. The vertex of the angle is located outside of the circle, while the two endpoints of the angle lie on the circle.

Circumscribed angles have some important properties in geometry. For example, the measure of a circumscribed angle is half the measure of its intercepted arc (the arc of the circle that lies inside the angle). Additionally, if two angles intercept the same arc of a circle, they are congruent.

Circumscribed angles also appear frequently in trigonometry, where they are used to define the sine, cosine, and tangent functions. The sine of a circumscribed angle is defined as the ratio of the length of the opposite side of the angle to the length of the circle's radius. The cosine of a circumscribed angle is defined as the ratio of the length of the adjacent side of the angle to the length of the radius.

Finally, the tangent of a circumscribed angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Estimate the volume of the snowpack in the park in cubic meters. (Give your answer as a whole or exact number.) V= ____billion m

Answers

The estimated volume of the snowpack in the park is approximately 1.94 billion cubic meters.

To estimate the volume of the snowpack in the park, we need to calculate a double integral of the function d(x, y) over the domain D:

V = ∬_D d(x, y) dA

We can evaluate this integral by using iterated integrals. First, we integrate with respect to x over the interval [0, 30] (since the line y = 180 - 2x intersects the x-axis at x = 90):

V = ∫_0^30 (∫_0^(180-2x) (-0.024x + 0.012y + 1.2) dy) dx

Simplifying the inner integral:

V = ∫_0^30 [-0.024xy + 0.006y^2 + 1.2y]_0^(180-2x) dx

V = ∫_0^30 (-0.432x^2 + 21.6x - 5832) dx

Simplifying the integral:

V = [-0.144x^3 + 10.8x^2 - 5832x]_0^30

V = -0.144(30)^3 + 10.8(30)^2 - 5832(30)

V = 1.942592 billion cubic meters (rounded to nine decimal places)

If the water boils at 196°F, approximate the altitude of the campers. Give the result to the nearest hundred feet

Answers

The Colorado hikers are at an altitude of 8753.1694 feet.

Here we have been given the equation T = -1. 83a + 212.

Here, T is the boiling point in Fahrenheit of water, while a is the altitude of the place.

We know that the campers in hiing in Colorado boil water for ea. The water boils at a temperature of 196°F, we need to find the altitude.

Here we are going to clearly take T = 196°F

Substituting the value in the above equation will give us

196 = - 1.83a + 212

Taking the variable to the Right Hand Side will give us

196 + 1.83a = 212

Taking 196 to LHS to separate the constant and variable will give us

1.83a = 212 - 196

Solving LHS gives us

1.83a = 16

Taking 1.83 to the other side will give us

a = 16/1.83

or, a = 8.7431694 thousands feet

= 8753.1694 feet

Hence, the Colorado hikers are at an altitude of 8753.1694 feet.

Two sisters, working together can clean the house in 3 hours. The older sister works 3 times faster than the younger sister when cleaning the house. How long will it take the younger sister to finish the same job by herself? Type just the number don't include words

Answers

The time taken by the younger sister to finish the same work by herself is 12 hours.

To solve the problem of how long it will take the younger sister to finish the job by herself, let's use the following terms:

1. Older sister's work rate = O
2. Younger sister's work rate = Y
3. Time taken by the younger sister alone = T

Given that the older sister works 3 times faster than the younger sister, we have:  O = 3Y.

Also, the sisters together can finish the job in 3 hours. Therefore, their combined work rate is equal to completing 1/3 of the job per hour. So,

O+Y=1/3.

Now, we can substitute O with 3Y:  3Y+Y=1/3. Combine the terms and simplify:

4Y=1/3

Now, solve for Y:

Y=1/12

Since Y is the work rate of the younger sister, to find the time it takes for her to complete the job alone (T), we can use the following formula:

Work rate × Time = 1 job.

So, Y × T = 1.

Substitute Y with  1/12:

[tex]\frac{1}{12} \times T=1[/tex]

Now, solve for T:

T = 12.

Therefore, it will take the younger sister 12 hours to finish the job by herself.

20 hours each week.


Which combinations allow Susan to work no more than 20 hours in one week and earn


at least $2402


Select the three correct combinations.

Answers

The required inequalities are h + l ≤ 20, 10h + 15l ≥ 240 and 20h + 25l ≥ 440

Given, for tutoring elementary students in math Susan earns $10 per hour. She earns $15 per hour for cleaning in the library.

Let h be the number of hours Susan works in one week tutoring elementary students.

Let l be the number of hours Susan works in one week cleaning the library.

Given that each week Susan cannot work more than 20 hours.

So, h + l ≤ 20 ....(1)

Susan's total earnings must be at least $240 per week.

10h + 15l ≥ 240    ...(2)

Multiplying equation (1) by 10

10h + 10l ≤ 200    ...(3)

Adding equations (2) and (3)

20h + 25l ≥ 440

Thus, the three required inequalities are h + l ≤ 20, 10h + 15l ≥ 240 and 20h + 25l ≥ 440
