g suppose we roll 20 fair six-sided dice. what is the probability that the minimum of the dice is 1?

Answers

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

Let X be a random variable representing the minimum value among 20 fair six-sided dice rolls. We are interested in finding P(X = 1).

The event {X = 1} occurs if and only if all 20 dice rolls result in a 1. The probability of a single dice rolling a 1 is 1/6, and the rolls are independent, so the probability of all 20 dice rolling a 1 is (1/6)^20. Hence,

P(X = 1) = (1/6)^20 = 1.275 * 10^-9.

Probability of getting minimum value of 20 fair dice rolls to be 1 is (1/6)^20 = 1.275 * 10^-9.

solve the sum-of-forces equation just derived, 0=∑ify,i=pa−(p dp)a−rhoagdy , to obtain an expression for dp and thus a differential equation for pressure.

Answers

The pressure gradient is a function of the pressure itself, the local acceleration due to gravity, and the density of the fluid.

The sum-of-forces equation is 0=∑ify,i=pa−(p dp)a−ρagdy. Rearranging the equation to isolate dp yields the following expression:

dp = (pa - ρagdy) / p

Differentiating both sides with respect to y yields the differential equation for pressure:

dp/dy = (a(pa - ρagdy) - (dp)(pa)) / p

This equation can be further simplified using the product rule to yield:

dp/dy = pa2/p2 - ρag/p.

This differential equation shows that the pressure gradient is a function of the pressure itself, the local acceleration due to gravity, and the density of the fluid.

Let random variable S represent the age of the attendees at a local concert. The following histogram shows the probability distribution of the random variable S.
Alfonso claims that the distribution of S is symmetric with a mean age of 36. Does the histogram support Alfonso's claim?

Answers

The histogram doesn't support Alfonso's claim and the correct option is 5: No, the distribution is skewed to the left with a mean age greater than 36.

What is a histogram?

A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.

Consider the given histogram at the photo below. It is an left-skew histogram, since it has a long tail to the left side.

We need to estimate the mean of the given data. To do so, we need to multiply each class midpoint with its probability, and sum them.

For example, for the first one, the midpoint is 32 and the probability is 0.03 (read the value on the y-axis). For, the second one, the midpoint is 33 and the probability is 0.04, for the third the midpoint is 34 and the probability is 0.05, and so on. All needed values are presented below.

1. midpoint = 32, probability= 0.03

2. midpoint = 33, probability = 0.04

3. midpoint = 34, probability = 0.05

4. midpoint = 35, probability = 0.1

5. midpoint = 36, probability =0.11

6. midpoint = 37, probability = 0.13

7. midpoint = 38, probability = 0.2

8. midpoint = 39, probability = 0.09

So, it is obtained that -

μ = 0.03 · 32 + 0.04 · 33 + 0.05 · 34 + 0.10 · 35 + 0.11 · 36 + 0.13 · 37 + 0.25 · 38 + 0.20 · 39 + 0.09 · 40

μ = 37.15

Tory and emilio's motorboats travel at the same speed Tory pilots her boat at 30 km before docking. Emilio continues for another 3 hr, traveling a total of 100 km before docking. How long did it take to navigate the 30 km​

Answers

The actual time it took Tory to travel 30 km is 0 hours.

As per the data given in the question,

Speed of the boat of both the person Tory and Emillio are same.

Let's call the time it took Tory to travel 30 km as "t" (in hours).

Emilio travelled for t + 3 hours, and during that time, he covered a total distance of 100 km.

So, we can write the equation:

30 + (t + 3) * 30 = 100

Solving for t:

30 + 30t + 90 = 100

30t = -60

t = -2

Since time cannot be negative, the actual time it took Tory to travel 30 km is 0 hours.

No, it does not follow that y is an interval or a ray in x. A convex subset of an ordered set is a set that contains all the points between any two points in the set.

This means that a convex subset of an ordered set could be a collection of points, it could be an interval, or it could be a ray. A proper subset of an ordered set is any subset except the entire set, so a proper subset of an ordered set could be any of these possibilities.

How are the average rate of change and the instantaneous rate of change related for ƒ(x) = 2x + 5?

Answers

The average rate of change and the instantaneous rate of change are same for ƒ(x) = 2x + 5. The solution has been obtained by using the concept of rate of change.

What is rate of change?

The pace at which one quantity changes in relation to another is described by the rate of change function. Simply expressed, the amount of change in one item is divided by the same amount of change in another to determine the rate of change. The relationship between how one quantity changes in relation to a change in another quantity is provided by the rate of change formula.

The average rate of change is:

[tex]r_{avg} =\frac{f(b)-f(a)}{b-a}[/tex], on interval [a,b]

Here, we are given  ƒ(x) = 2x + 5

So,

[tex]r_{avg} =\frac{(2b+5)-(2a+5)}{b-a}[/tex]

[tex]r_{avg} =\frac{2b-2a}{b-a}[/tex]

[tex]r_{avg} =2[/tex]

The slope of f assessed at a single point, such as f′(c), where c is a predetermined point, is the definition of the instantaneous rate of change.

So, for ƒ(x) = 2x + 5,

f′(c) = 2

Therefore, instantaneous rate of change is 2.

Hence, the average rate of change and the instantaneous rate of change are same for ƒ(x) = 2x + 5.

What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

For 1 minute 20 feet

For 60 minutes , 60*20=1200 feet

1 hour = 60 minutes

Thus, we have 1200 feet per hour

The cube root symbol is represented by the number "3". In the square root case, only the root symbol—also known as a radical—was employed. Therefore, the cube root of different numbers can be symbolically represented as follows: 5 divided by its cube = 3. 11 has a cube root of 311 and so on.

What does a cube of 3 inches mean?

The cube root of three is the same as the number 1.442224957031. The cube root of three has the radical representations 33 and 31/3. " denotes the square root.

The cube root formula aids in computing the cube root of any given number that is represented by the symbol in radical form. It can be determined by first determining the number's prime factorization and then using the cube root formula. Assume that x is any number such that it equals y, y, and y.

Match each graph to its equation

Answers

Answer is
Graph A = equation a

Graph B = equation c

Graph C = equation b

Graph D = equation d

Step by step

Equation a is a positive slope of 2 with a y intercept of 3. Only A and B have positive slopes (going up from left to right) and only A has the y intercept of +3, so A is your match with equation a

Equation b is a negative slope of 2 (going down left to right) with a y intercept of 3. Graph C is the only other graph with a y intercept of 3, so graph C is a match to equation b.

Equation c is a slope of positive slope of 2 with a y intercept of -3. Graph B is a positive slope with a y intercept of -3, so graph B is a match to equation c.

Equation d is a negative slope of -2 with a negative y intercept of -3. Graph D is a negative slope with a y intercept of -3, so graph D matches with equation d.

withω=seiφ,wheres≥0andφ∈r,solvetheequationzn =ωincwhere n is a natural number. how many solutions are there?

Answers

For an nth root, there are n solutions of the equation z^n = ω.

To find these solutions, we use the polar form of z = r * e^(iθ). Substituting into the equation, we get:

r^n * e^(iθn) = s * e^iφ

Comparing the magnitude of both sides, we have:

r^n = s

Comparing the phase of both sides, we have:

nθ = φ + 2πk (where k is an integer)

So, we can set:

r = s^(1/n)

θ = (φ + 2πk) / n

Therefore, the n solutions are:

z = s^(1/n) * e^(i(φ + 2πk) / n)

for k = 0, 1, 2, ..., n-1.

in isosceles trapezoid mnpq with , diagonal . if and , how long is diagonal ?

Answers

The value of segment RN is:

Rn = 1.8

Now, According to the question:

An isosceles trapezoid is a trapezoid with congruent base angles and congruent non-parallel sides. A trapezoid is a quadrilateral with only one of its sides parallel. An isosceles trapezoid has many interesting properties that make it unique and help us differentiate it from the other quadrilaterals.

The figure shows:

MQ is parallel to NP

MN ≅ QP

So MNPQ is an isosceles trapezoid. That means that the two diagonals, MP and QN, are congruent and therefore are equal in length;

MP = QN

By the Segment Addition Postulate, QN = QR + RN and QR = 4.1:

MP = QN

5.9 = 4.1 + RN

RN = 5.9 - 4.1

RN = 1.8
