Drawing a ball from a bag without looking is an example of simple random sampling.

As we know the degree to which we believe the distributions of outcomes are fair is referred to as outcome fairness.

These outcomes can include things like pay, perks, promotions, and other physical things, but they can also include things like praise and other forms of social recognition.

Step-by-step explanation:

I took the quiz on EDGE 2022

The measure of the length of the dotted line is 3.75 inches. Then the correct option is B.

The hexagon is a two-dimensional geometry with six sides. And the polygon's sides are all straight lines that are joined side by side.

The perimeter of the hexagon is 7.5 inches.

Then the length of the hexagon will be

[tex]\rm 7.5 = 6x\\\\x \ \ = 1.25[/tex]

The length of the hexagon is 1.25 inches.

Then the diagonal length of the hexagon will be

y = 2 × 1.25

y = 2.5

The diagonal length of the hexagon is 2.5 inches.

Then the length of the dotted line is 3.75 inches.

Answer:

4x+3y=23

Step-by-step explanation:

4x+3y=23

2x+6y=34 multiply equation by 2 to get x values equivalent, so

4x+12y=68 now subtract firs equation from this

-(4x+3y=23)

so 9y=45 and y=5

now find x:

4x+3(5)=23

4x+15=23

4x=8

x=2

So, hamburgers cost $2 and chicken nuggets $5.

Answer:

[tex]3/4[/tex]

Step-by-step explanation:

We are asked to find the difference which means we will be using subtraction.

We are given two numbers to use [tex]4\frac{1}{12}[/tex] (Houston to Dallas) & [tex]3\frac{1}{3}[/tex] (San Antonio to Houston).

To be able to subtract, we need to have the same denominator on both fractions, which we can do by multiplying 1/3 by 4

[tex]\frac{1}{3} * 4=\frac{4}{12}[/tex]

now we can subtract the numbers and simplify!

Total number of chips

Probability of a blue chip

The subsequent blue has same probability as the chip is replaced.

Probability of two blue chips is

Answer:

[tex]\sf \dfrac{9}{169}[/tex]

Step-by-step explanation:

The bag has:

⇒ Total number of chips = 6 + 13 + 7 = 26

Probability Formula

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Probability of choosing a blue chip from the first draw:

[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]

As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.

Therefore, the probability of taking out a blue chip in both draws is:

[tex]\begin{aligned}\implies \sf P(Blue)\:and\:P(Blue) & = \sf \dfrac{6}{26} \times \dfrac{6}{26}\\\\& = \sf \dfrac{6 \times 6}{\26 \times 26}\\\\& = \sf \dfrac{36}{676}\\\\& = \sf \dfrac{36 \div 4}{676 \div 4}\\\\& = \sf \dfrac{9}{169}\end{aligned}[/tex]

The method of pay that would result in the most earnings is: Option d. graduated commission of 5% on the first $40,000 in sales and 9% on anything over that.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We're specified that:

Calculating the earnings from all the options:

That means, we get:
Earning = 6% of 60,000 = [tex]\dfrac{60000}{100} \times 6 = 3600[/tex] (in dollars)

That means:

Earning = 1500 + 3% of 60,000 = [tex]1500 +\dfrac{60000}{100} \times 3 = 1500 + 1800 = 3300[/tex] (in dollars).

That means, we get:

Earning = 4% of 50,000 + 10% of 10,000 (as total 60,000 dollars sales was done).

Earning = [tex]\dfrac{50000}{100} \times 4 + \dfrac{10000}{100} \times 10 = 2000 + 1000 = 3000[/tex] (in dollars)

That means:

Earning = 5% of 40,000 + 9% of 20,000 (as 40000 + 20000 = 60000)

or, we get:

Earning = [tex]\dfrac{40000}{100} \times 5 + \dfrac{20000}{100} \times 9 = 2000 + 1800 = 3800[/tex] (in dollars).

Thus, option D provides the method for max earning.

Thus, the method of pay that would result in the most earnings is: Option d. graduated commission of 5% on the first $40,000 in sales and 9% on anything over that.

Step-by-step explanation: i took the test

Using the binomial distribution, it is found that there is a 0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, there are 20 students, hence in each question the probability that Milani's name is called is p = 1/20 = 0.05.

The probability that the teacher first draws Milani's name as the 7th student is P(X = 0) when n = 6(none during the first six) multiplied by 0.05(called during the seventh), hence:

P(X = 7) = (0.95)^6 x 0.05 = 0.0368.

0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.

Answer:

D  4+p=24

Step-by-step explanation:

So P stands for Paul & how much he spent.

Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20.  So P = $20

So which equation would work if you substituted $20 for P?

4 + P = 24

4 + 20 = 24

Answer:

2√3

Step-by-step explanation:

root 27

= √27

= 3√3

12 upon root 3

= 12 / √3

= ( 12 / √3 ) x ( √3 / √3 )

= ( 12 x √3 ) / ( √3 x √3 )

= 12√3 / 3

= 4√3

6 upon √3

= 6 / √3

=  ( 6 / √3 ) x ( √3 / √3 )

= ( 6 x √3 ) / ( √3 x √3 )

= 6√3 / 3

= 2√3

root 3 = √3

root 3 + root 27 - 12 upon root 3 + 6 upon root 3

= √3 + 3√3 - 4√3 + 2√3

The total amount of money that Stephen would pay his uncle is equal to $10,600.

Mathematically, simple interest is calculated by using this formula:

I = PRT

Where:

Given the following data:

Interest rate = 2% = 0.02.

Principal = $10,000.

Time = 3 years.

Substituting the given parameters into the formula, we have;

I = 10000 × 0.02 × 3

I = $600.

Amount of balance;

A = I + P

A = 600 + 10,000

These are the three basic trigonometric ratios:

Here, 'opposite' or adjacent are referring to the legs in relation to one of the interior angles of the triangle, θ.

We can use these ratios to help us solve for side lengths or angles, depending on what information is given to us and what information we must solve for.

We're given:

Because this question involves the adjacent and the opposite, we can use the tangent ratio to find the answer.

[tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]

⇒ Plug in the given information:

[tex]\tan(70^\circ)=\dfrac{opposite}{5.7}[/tex]

⇒ Multiply both sides by 5.7 to isolate 'opposite:

[tex]5.7\tan(70^\circ)=opposite\\opposite = 15.66062\dots[/tex]

⇒ Round to the nearest tenth:

[tex]opposite=15.7[/tex]
