suppose the die is tossed and we are told that the result is a number greater than 4 4 . based on this information, what is the probability that the result was a 6 6 ?

If fires occur at points uniformly chosen on (0, A), then [tex]a = \frac{A}{2}[/tex] is the second derivative where should the station be located so as to minimize the expected distance from the fire.

From the question, a fire station is to be located along a road of length A, A < ∞.

If fires occur at points uniformly chosen on (0, A), then we have to find where should the station be located so as to minimize the expected distance from the fire.

E∣X−a∣ = [tex]\int^{A}_{0}|x-a| \frac{1}{A} dx[/tex]

E∣X−a∣ = [tex]\int^{a}_{0}|a-x| \frac{1}{A} dx+\int^{A}_{a}|x-a| \frac{1}{A} dx[/tex]

Now integrating.

E∣X−a∣ = [tex]\frac{1}{A}\left(\frac{a^2}{2}+\frac{A^2}{2}-aA-\left(\frac{a^2}{2}-a^2\right)\right)[/tex]

E∣X−a∣ = [tex]\frac{a^2}{A}-a+\frac{A}{2}[/tex]

If we set the derivative to zero, we get [tex]\frac{2a}{A}-1=0[/tex], where [tex]a = \frac{A}{2}[/tex] is the derivative. One can look at the second derivative, which is always positive, to see if this is the minimizer.

Null hypothesis: H₀ : μ = 55

Alternative hypothesis: H₁: μ [tex]\neq[/tex] 55

Given,

Rating = 55 mpg

For a two-tailed alternative hypothesis, it involves the "not equal to symbol,≠ ". This can never be in the null hypothesis. In order to reject the null hypothesis, the test statistic must be smaller than the critical value on the left tail or greater than the critical value on the right tail.

the claim is the jeep has a 55 mpg rating and we want to test whether the rating is correct or incorrect. So, it is a two-tailed hypothesis because the rating can be less than or more than 55 mpg.

Therefore, H₀ : μ = 55

H₁: μ [tex]\neq[/tex] 55

a. The probability of exactly two US adults having a mental illness in a sample of six is 0.235904

B. The probability of at least one US adult having a mental illness is >=21

C. The probability of less than three US adults having a mental illness is <=3

a. The probability of exactly two US adults having a mental illness in a sample of six is given by the binomial probability formula:

P(X = 2) = (6 choose 2) * (0.2)^2 * (0.8)^4 = 0.235904

b. To find the probability of at least one US adult having a mental illness, we need to find the probability of zero or one or two or three or four or five or six US adults having a mental illness.

This can be found by summing the probabilities of each event:

P(X >= 1) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

c. To find the probability of less than three US adults having a mental illness, we need to find the probability of zero or one or two US adults having a mental illness.

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

Note that the binomial probability formula can be used to find the individual probabilities as well.

Answer: consecutive interior angles and x=66°

Step-by-step explanation:

The angles are consecutive interior angles. The property is consecutive interior angles are supplementary.

2x+24+24=180          [combine like terms]

2x+48=180                 [subtract both sides by 48]

2x=132                       [divide both sides by 2]

x=66

Therefore, the angle is consecutive interior angles and x=66°.

We know that the formula for the percent error is:

Percent Error = (Absolute Error ÷ Actual Value) × 100

where, Absolute Error = ∣Actual Value - Estimated Value|

In this situation, the actual value is 65 mph and the Estimated value is 55 mph.

So, using above formula for absolute error,

Absolute Error = ∣Actual Value - Estimated Value|

Absolute Error = ∣65 - 55|

Absolute Error = 10

The rate at which the volume of the snowball is changing at the instant the radius is 6 cm is -241.27 cm³/min.

The volume of a sphere is given by the formula V = 4/3πr³, where r is the radius of the sphere. To find the rate at which the volume is changing, we need to take the derivative of this equation with respect to time, using the chain rule.

dV/dt = 4/3π(3r²) dr/dt

We know that the radius of the snowball is decreasing at a constant rate, so we can find the value of dr/dt by using the information given in the problem. The radius is decreasing from 34 cm to 18 cm in 30 minutes, which means that:

dr/dt = (34 - 18) cm / 30 minutes = -0.5333 cm/min

Now that we know the rate at which the radius is changing, we can substitute it into the equation for dV/dt and find the rate at which the volume is changing.

We know that the radius is 6 cm at the instant the volume is changing, so we can substitute that into the equation:

dV/dt = 4/3π(3r²) dr/dt = 4/3(π)(3)(6 cm)²(-0.5333 cm/min) = -241.27 cm³/min

So, the rate at which the volume of the snowball is changing at the instant the radius is 6 cm is -241.27 cm³/min.

Note that the negative sign indicates that the volume is decreasing.

The shortest possible height of the vase rounded to the nearest tenth of a centimetres is 45.650.

The concept of rounding the numbers will be used here to find the answer. Concerning this, we must know, that a number will be rounded to next digit, if the subsequent number if 5 or more than 5.

We know 6 preceedes 7 and the number is rounded to nearest tenth. So, the just possible number will be 45.69. However, as mentioned, it will be rounded to 45.7. The same will happen for till 45.65. Proceeding before this, we get 45.64 which will not be rounded to 45.7. Thus, the smallest possible number is 45.65 centimetres.

For example, for the rational function [tex]f(x)=\frac{1}{x}[/tex], there's a horizontal asymptote at y=0 because as x approaches infinity, y gets increasingly closer to 0.

Answer: 26 units

Step-by-step explanation:

Let's label the left side as side a, the bottom as side b, and the hypotenuse (the diagonal side) as side c.

As you can see, side a is 8 units, and side b is 7 units. To calculate side c, you need to plug both a and b in to the Pythagoras' theorem, which states that a² + b² = c².

> 8² + 7² = c²

> 64 + 49 = c²

> 113 = c²

> c = 10.63 which would round up to 11.

Now adding up all the sides together, a + b + c = 7 + 8 + 11 = 26 units

The probability that the ticket drawn at random has a multiple of four or five is 2/5.

We have to determine the probability that the ticket drawn at random has a multiple of four or five.

Tickets number 1 to 20 are mixed up and then a ticket is drawn at random.

Total number of tickets = 20

The possible numbers of tickets that are multiple of four or five = 4, 5, 8, 10, 12, 15, 16, 20

So total number of outcome that are multiple of four or five = 8

So, the probability that the ticket drawn at random has a multiple of four or five = Total number  of outcome that are multiple of four or five/Total number of tickets

The probability that the ticket drawn at random has a multiple of four or five = 8/20

The probability that the ticket drawn at random has a multiple of four or five = 2/5

Imagine Y to be number of papers till we get all grades once. Hence

Yi= Number of papers till we get i th newer grades

Expected value of Y₆= ?

The difference between getting a new grade maybe represented as

Xi= Yi+1 - Yi

Using above equation for Y₆, we get

[Y₆]= ∑⁵i=o Xi

which means, we need to get 5 different grades from the first grade.

Number of tries to see second new grade maybe represented as

X₁= {(6-1)/6}, which, for generalization is written as Xi=geo{(6-i)/6}

Xi represents the success probability of seeing further new grade.

Expected value of Xi is inverse of parameter of geometric distribution, which is,

[Xi] = 6/(6-i) = 6.{1/(6-i)}

Expected value of Y₆= [∑⁵ i=0 Xi] = ∑⁵ i=0 [Xi]

Substituting value of [Xi] in the above expression

6.∑⁵i=0 {1/(6-i)} = 6. ∑⁶i=1 (1/i)
