What’s the product of this

The probability that Grant will select a blue sock and then a green sock = [tex]\frac{8}{95}[/tex].

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.

The probability that Grant will select a blue sock and a green sock =

= Probability of choosing a blue sock * Probability of choosing a green sock out of the remaining socks

=  [tex]\frac{Number\ of\ blue\ socks}{Total\ number\ of\ socks} * \frac{Number\ of\ green\ socks\ out\ of\ remaining\ socks }{Total\ number\ of\ remaining\ socks}[/tex]

= [tex]\frac{4}{20} * \frac{8}{19} = \frac{8}{95}[/tex]

Answer:

Value of x using quadratic formula (x = -4) and (x = -5)

Step-by-step explanation:

Given:

Equation

x² + 9x + 20 = 0

Find:

Value of x using quadratic formula

Computation:

Quadratic formula = [-b±√b²-4ac] / 2a

Given equation;

x² + 9x + 20 = 0

a = 1 , b = 9 , c = 20

By putting value

[-9±√9²-4(1)(20)] / 2(1)

[-9±√81-80] / 2

[-9±√1] / 2

(-9 + 1) / 2 , (-9 - 1) / 2

-8 / 2 , 10 / 2

($2.19,$2.39)

Step-by-step explanation:

Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

When the sample size is less than 30, the formula which is used is,

[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]

Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.

Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,

[tex]n=12[/tex]

Thus, degree of freedom,

[tex]df=12-1\\df=11[/tex]

In the t table, for df 11, the value of t is 1.796.

An economist studying fuel costs wants to estimate the mean price of gasoline in her state on a certain day.

On that day, she takes an SRS of 12 gas stations and finds the sample mean price (in dollars per gallon) is,

[tex]\bar x=2.29[/tex]

With a standard deviation of

[tex]s_x=0.20[/tex]

Put the values in the above formula,

[tex]2.29\pm 1.796.\dfrac{0.20}{\sqrt 12}\\2.29\pm 0.1037\\2.29+0.1037=2.3937\\2.29- 0.1037=2.1863[/tex]

Thus, based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

Answer:

the mean is 9

Step-by-step explanation:

add all the numbers then divide by 6

Answer:

The mean is 9.

Step-by-step explanation:

The mean of a data set is all of the numbers added together, divided by how many numbers are present.

For instance, 10+10+8+9+7+10 = 54.

Since there are 6 numbers in this data set, you divide 54 by 6 and get 9.

Therefore, the mean of this data set is 9.

Answer:

A White Marble

Step-by-step explanation:

The chance of choosing a white marble is 7/12 (amount of red marbles = 2 because there is no exact number, the problem only states there are more than one marble. To find probability, add all of the possible changes combinations of choosing a marble from the bag. ( 3 + 7 + 2 = twelve. After finding how many possible combinations there are, subtract the # of possible combinations from the # of marbles that are not white. ( 12 - 5 = 7 ). Finally, put the amour of white marbles next to the # of possible combinations. (7/12)

Step-by-step explanation:

Since they do not replace it the total amount of marbles are the same
