Answer:

Probability = 0.12

Step-by-step explanation:

Given : A drawer contain  4 red, 3 white , 3 blue socks

Total number of outcomes(S)= 10

Favorable event for first sock(B) ={3 blue sock}=3

Probability of picking first sock which is blue = favorable outcome/ total number of outcome P(B) = 3/10

since replacement is there

therefore, total no of outcomes remain same = 10

Favorable event for second sock(R) ={4 red sock}=4

then, probability of picking second sock which is red =favorable outcome/ total number of outcome P(R) = 4/10

Now, probability that the first sock is blue and the second sock is red is

P(B and R)= P(B) × P(R) = 3/10 ×4/10 = 12/100 = 3/25

Probability of events = 0.12

The probability that the first sock is blue and the second sock is red is:
(3/10) * (4/10)=3/25.

yan [13]

Step-by-step explanation:

An exponential growth function can be written in the form y = abx where a > 0 and b > 1. The graph will curve upward, as shown in the example of f(x) = 2x below. Notice that as x approaches negative infinity, the numbers become increasingly small.

Himpunan penyelesaian pertidaksamaan nilai mutlak |2x-4| > |3x+2|
Stells [14]

Answer:

The solution in interval notation is:

(-6,\frac{2}{5}).

The solution in inequality notation is:

-6.

Step-by-step explanation:

I think you are asking how to solve this for x.

Keep in mind |x|=\sqrt{x^2}.

|2x-4|>|3x+2|

\sqrt{(2x-4)^2}>\sqrt{(3x+2)^2}

If \sqrt{u}>\sqrt{v} then u>v.

(2x-4)^2>(3x+2)^2

Subtract (2x-4)^2 on both sides:

0>(3x+2)^2-(2x-4)^2

Factor the difference of squares a^2-b^2=(a-b)(a+b):

0>((3x+2)-(2x-4))((3x+2)+(2x-4))

Simplify inside the factors:

0>(x+6)(5x-2)

(x+6)(5x-2)

The left hand side is a parabola that faces up.  I know this because the degree is 2.  

The zeros of the the parabola are at x=-6 and x=2/5.

We can solve x+6=0 and 5x-2=0 to reach that conclusion.

x+6=0

Subtract 6 on both sides:

x=-6

5x-2=0

Add 2 on both sides:

5x=2

Divide both sides by 5:

x=2/5

Since the parabola faces us and (x+6)(5x-2) then we are looking at the interval from x=-6 to x=2/5 as our solution.  That part is where the parabola is below the x-axis.  We are looking for where it is below since it says the where is the parabola<0.

The solution in interval notation is:

(-6,\frac{2}{5}).

The solution in inequality notation is:

-6.

If all possible random samples of size n are taken from a population, and the mean of each sample is determined, the mean of the
NemiM [27]

Answer:

A. exactly the same as the population mean.

Step-by-step explanation: This demonstration illustrates Rule 1 of the Central Limit Theorem: The mean of the population and the mean of the sampling distribution of means will always have the same value. Thus, the sampling distribution of the mean will have a normal shape, even though the population distribution does not.

To calculate the mean, add up all the values and divide by the number of values. There are two types of arithmetic mean: population mean and the sample mean.
