Answer:

  61/121

Step-by-step explanation:

With replacement, the different outcomes have probabilities ...

  P(r, r) = (5/11)(5/11) = 25/121

  P(r, b) = (5/11)(6/11) = 30/121

  P(b, r) = (6/11)(5/11) = 30/121

  P(b, b) = (6/11)(6/11) = 36/121

These outcomes are mutually exclusive, so the probability of any combination of them is the sum of their individual probabilities.

  P(x, x) = P(r, r) +P(b, b) = 25/121 +36/121 = 61/121

The probability of two the same color is 61/121.

The true proportion of the side lengths of the quadrilaterals is A'B'/AB

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

Quadrilaterals ABCD and A'B'C'D

These quadrilaterals are similar

So, it means that the corresponding side lengths are proportional

So. we have

Side length = AB

Corresponding side length = A'B'

The true proportion is then represented as

k = Corresponding side length/Side length

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

k = A'B'/AB

Hence, the proportion is A'B'/AB

a. The given geometric series with a = 486, r = 1/3 is convergent.

To determine if a geometric series is convergent, we need to check if the common ratio (r) is between -1 and 1 (excluding -1 and 1). In this case, 1/3 satisfies the condition, so the series is convergent.

To find the sum (S) of a convergent geometric series, we can use the formula:

S = a / (1 - r)

Plugging in the values, we have:

S = 486 / (1 - 1/3)

S = 486 / (2/3)

S = 729

Therefore, the sum of the series is S = 729.

b. The given geometric series with a = 2 and r = 5 is divergent.

In this case, the common ratio (r = 5) is greater than 1, which means the series is divergent. Therefore, the sum of the series is not applicable (N/A) or "Soo" (using the input pallet).

c. The given geometric series with a = 4 and r = 3 is divergent.

Similar to the previous case, the common ratio (r = 3) is greater than 1, indicating that the series is divergent. Thus, the sum is not applicable (N/A) or "Soo."

d. The given geometric series with a = -28125 and r = 1/5 is convergent.

The common ratio (r = 1/5) satisfies the condition of being between -1 and 1, making the series convergent.

To find the sum (S) of this convergent geometric series, we can use the formula:

S = a / (1 - r)

Plugging in the values, we have:

S = -28125 / (1 - 1/5)

S = -28125 / (4/5)

S = -140625

Therefore, the sum of the series is S = -140625.

The statement "the t distribution is a family of similar probability distributions" is True.

The t-distribution is indeed a family of similar probability distributions. It is used in statistics to model the distribution of a random variable when the sample size is small and the population standard deviation is unknown. The shape of the t-distribution depends on the degrees of freedom, which is determined by the sample size. As the degrees of freedom increase, the t-distribution approaches the shape of the standard normal distribution.

The t-distribution is symmetric and bell-shaped like the normal distribution, but it has heavier tails, which means it has more probability in the tails and less in the center compared to the normal distribution. The t-distribution plays a crucial role in hypothesis testing and constructing confidence intervals when working with small samples.

1. The graph opens downward.

2. The graph has a maximum value.

4. The maximum height is approximately 22.704 yards.

5. Increasing the coefficients makes the parabola narrower and steeper, while decreasing them makes it wider and flatter.

1. The graph of the quadratic function y = -0.0352x² + 1.4x + 1 opens downwards. This can be determined by observing the coefficient of the squared term (-0.0352), which is negative.

2. The graph of the quadratic function has a maximum value. Since the coefficient of the squared term is negative, the parabola opens downward, and the vertex represents the maximum point of the graph.

3. To graph the quadratic function y = -0.0352x² + 1.4x + 1, we can plot points and sketch the parabolic curve. Here's a rough representation of the graph:

Graph of the quadratic function

The x-axis represents the distance (in yards) the football is kicked (x), and the y-axis represents the height (in yards) the football reaches (y).

4. To find the maximum height of the football, we can determine the vertex of the quadratic function. The vertex of a quadratic function in the form y = ax² + bx + c is given by the formula:

x = -b / (2a)

In this case, a = -0.0352 and b = 1.4. Plugging in the values, we have:

x = -1.4 / (2 * -0.0352)

x = -1.4 / (-0.0704)

x ≈ 19.886

Now, substituting this value of x back into the equation, we can find the maximum height (y) of the football:

y = -0.0352(19.886)² + 1.4(19.886) + 1

Performing the calculation, we get:

y ≈ 22.704

Therefore, the maximum height of the football is approximately 22.704 yards.

5. If the coefficients of the "2" and "a" terms were increased, it would affect the shape and position of the graph. Specifically:

Increasing the coefficient of the squared term ("2" term) would make the parabola narrower, resulting in a steeper downward curve.

Increasing the coefficient of the "a" term would affect the steepness of the parabola. If it is positive, the parabola would open upward, and if it is negative, the parabola would open downward.

On the other hand, decreasing the coefficients would have the opposite effects:

Decreasing the coefficient of the squared term would make the parabola wider, resulting in a flatter downward curve.

Decreasing the coefficient of the "a" term would affect the steepness of the parabola in the same manner as increasing the coefficient, but in the opposite direction.

These changes in coefficients would alter the shape of the parabola and the position of the vertex, thereby affecting the maximum height and the overall trajectory of the football.

The domain of the function g(x) = x² - 100 is(-∞, -10] ∪ [10, ∞)

The domain of the function g(x) = x² - 100 can be expressed using interval notation as follows:Domain: (-∞, -10] ∪ [10, ∞)

The given function g(x) = x² - 100 is a polynomial function.

There are no restrictions or limitations on the domain of a polynomial function, i.e., all real numbers can be used as input to the function.

However, in this particular function, we have a subtraction of 100.

Since we cannot have a square root of a negative number, we need to ensure that the radicand (x² - 100) is non-negative.

Thus, we have:x² - 100 ≥ 0⇒ x² ≥ 100⇒ x ≤ -10 or x ≥ 10

The rate of change of the angle of elevation is -2π/3 radians/second.

We can use the tangent ratio to solve this problem. Since the rope is attached to the boat, we can draw a right triangle with the rope as the hypotenuse. The angle of elevation is the angle formed by the rope and the horizon.

The pulley is 5 feet above the water level, so the length of the opposite side (the side adjacent to the angle) is 5 feet. The length of the hypotenuse is 12 feet, since the boat is 12 feet from the dock.

Using the tangent ratio, we can calculate the angle of elevation:

tan(θ) = opp/hyp = 5/12

θ = arctan(5/12) = 0.927 rad

Now, since the rope is being pulled in at 3 ft/sec, the length of the hypotenuse is decreasing at a rate of 3 ft/sec. Therefore, the rate of change of the angle of elevation is:

rate of change of θ = -(3 ft/sec) / (12 ft) = -2π/3 radians/second

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time. The speed of the car is 50 km/h. The speed of truck is 70 km/h.

You can determine an object's speed if you know how far it moves in a given amount of time. For instance, an automobile is moving at a pace of 70 miles per hour if it covers 70 miles in an hour (miles per hour).

Given,

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time.

Let s represent the truck's speed and (s+20) represent the car's speed.

to determine each vehicle's time

Time = Speed / Distance

truck time = 350/s

Time in an automobile is 350/(s+20)

Truck time - car time = 2 hours

So,

(350/s) - [350/(s+20)] = 2

LCM is s(s+20)

[350(s+20) - 350s]/s(s+20) = 2

Cross multiplying,

350(s+20) - 350s = 2s(s+20)

Simplifying the equation,

350s + 7000 - 350s = 2s² + 40s

Now, we have quadratic equation to simplify,

2s² + 40s - 7000 = 0

Dividing the equation by 2

s² + 20s - 3500 = 0

Factorizing,

s= 50

s= -70 (impossible because of the sign)

Hence the truck's speed is s = 50 km/h.

The speed of the car is s + 20 = 70 km/h.
