The probability distribution for the statistic is ; for m = 0 , P(0) =  0.216  , for m = 5 ,P(5) = 0.296 and for m = 10 , P(10) = 0.488  .

In the question ,

it is given that ,

the box has 10 sealed envelopes , that contains number from 1,2,...,10 .

the first six envelopes has no money .

next two envelopes has $5

and the last two contains $10 bill .

if x₁, x₂, and x₃ denote the amounts in the selected envelopes,

the statistic of interest is m = maximum of X₁ , X₂ and X₃ .

we need to find probability distribution for the statistic m,

So , P(m = 0) = P( all three envelope contains no money) = (6/10)³ = 0.216

and P(m = 5) = P( all from 8 envelope which contains at most $5) - P(all three envelope with 0 money)

= (8/10)³ - 0.216

= 0.296

and P(m = 10) = 1 - (8/10)³ = 0.488

Therefore , the required probability is P(0) = 0.216 ,   P(5) =  0.296 and P(10) = 0.488  .

The probability of randomly picking a school or library-related issue from the ballot is 9/19 or approximately 0.474 (rounded to three decimal places).

To determine the probability of a randomly picked issue being school or library related, you'll need to consider the total number of issues and the number of school and library issues combined.

There are 7 school-related issues, 10 ordinance-related issues, and 2 library-related issues, making a total of 19 issues on the ballot. To find the probability of picking a school or library issue, combine the number of school and library issues: 7 + 2 = 9.

Now, divide the number of school and library issues (9) by the total number of issues (19): 9/19.

its m=185t

Step-by-step explanation:

because if you divide

An equation which represent the total meters (m) that Sam runs in t minutes is: B. m = 185t.

Mathematically, a proportional relationship can be represented with the following equation or mathematical expression:

m = kt

Where:

Next, we would determine the constant of proportionality (k) for each candy as follows:

From Jacob's running, we have the following:

Constant of proportionality (k) = t/m

Constant of proportionality (k) = 400/2

Constant of proportionality (k) = 200

Since Sam runs 15 meters less each minute than Jacob does, an equation that represent the total meters (m) that he runs in t minutes is given by:

m = (200 - 15)t

m = 185t

A

Step-by-step explanation:

slope -3

y intercept (0,2)

Option A is correct, y=-3x+2 is the equation of the line that best represents the graph of the line.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line passing through points (1, -1) and (-2, 8)

m=8+1/-2-1

m=-3

Now let us find the y intercept

8=-3(-2)+b

8=6+b

2=b

y=-3x+2 is the equation of line.

Hence, y=-3x+2 is the equation of the line that best represents the graph of the line.

Answer:

How many pink erasers do the students in your class have?

Answer:

a) 0.1138 = 11.38% probability that 14 of them were very confident their major would lead to a good job

b) 0.0483 = 4.83% probability that 10 of them are NOT confident that their major would lead to a good job

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

a. A 2017 poll found that 53% of college students were very confident that their major will lead to a good job. If 30 college students are chosen at random, what's the probability that 14 of them were very confident their major would lead to a good job?

Here, we have that \(p = 0.53, n = 30\), and we want to find \(P(X = 14)\). So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 14) = C_{30,14}.(0.53)^{14}.(0.47)^{16} = 0.1138\)

0.1138 = 11.38% probability that 14 of them were very confident their major would lead to a good job.

b. A 2017 poll found that 53% of college students were very confident that their major will lead to a good job. If 30 college students are chosen at random, what's the probability that 10 of them are NOT confident that their major would lead to a good job?

10 not confident, so 30 - 10 = 20 confident. This is P(X = 20).

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 20) = C_{30,20}.(0.53)^{20}.(0.47)^{10} = 0.0483\)

0.0483 = 4.83% probability that 10 of them are NOT confident that their major would lead to a good job

Answer: 21:9 and 42:18

Step-by-step explanation:

14:6 at its most basic form is 7:3, so find anything that could be equal to this if a number is multiplied on both sides.

21:9 is our simplified ratio multiplied by 3 on both sides.

42:18 is our simplified ratio multiplied by 6 on both sides.

But, the final ratio doesn't work, because 7 and 3 respectively cannot multiply to 13 and 8 with the same value.

Hey there! I'm happy to help!

We see that y is equal to 3/2x-2. We can replace the y in the first equation with 3/2x-2 because they are equal and we can solve for x.

3x-2(3/2x-2)=-8

We use the distributive property to undo the parentheses.

3x-3x+4=-8

We combine like terms.

4=-8

We see that since there is no x anymore, there cannot be a solution. We have no x value to solve for the y value either, so there is no solution to this system of equations.

a. The sample space, S, is the set of possible outcomes of a random experiment.

Let the experiment be "select a letter at random from the word pineapple" each word will represent possible outcomes of the sample space to that:

The word has a total of 9 letters, which are:

3 P

2 E

1 I

1 A

1 N

The sample space can be defined as:

(Note: I ordered the sample space alphabetically)

b. You have to determine which event has the highest probability, selecting letter at random and the result being an E or a P. Before you can compare the probabilities of both letters, you have to calculate them:

To determine the said individual probabilities, you have to calculate the quotient between the number of favorable cases and the number of total cases.

For the event "selecting a word at random and the letter is E"

- The total number of cases is 9 (number of letters on the word pineapple)

- The number of favorable cases is 2 (times the letter E is in the word pineapple)

For the event "selecting a word at random and the letter is P"

- The total number of cases is 9 (number of letters on the word pineapple)

- The number of favorable cases is 3 (times the letter P is in the word pineapple)

The probability of selecting the letter "E" is 0.22 while the probability of selecting the letter "P" is 0.33.

Then selecting the letter "P" is more likely than selecting the letter "E"

To solve the equation -3 + m = 9, we can isolate the variable m by moving the constant term -3 to the other side of the equation.

-3 + m = 9

To move -3 to the other side, we can add 3 to both sides of the equation:

-3 + 3 + m = 9 + 3

Simplifying, we have:

m = 12

Therefore, the value of m that satisfies the equation -3 + m = 9 is m = 12.
