The mean and standard deviation of the sampling distribution of the sample mean for samples of size 4 is 35.2435.24 and 9.549.54 respectively.

The mean and standard deviation of the sampling distribution of the sample mean for a sample size of 4 is calculated by first taking the population mean, which is 35.2, and dividing it by the square root of the sample size, which is 4. This gives us a mean of 35.2435.24. The standard deviation of the sampling distribution of the sample mean is calculated by taking the population standard deviation, which is 9.5, and dividing it by the square root of the sample size, which is 4. This gives us a standard deviation of 9.549.54. The formula for calculating the mean and standard deviation of the sampling distribution of the sample mean is:

Mean = Population Mean/ √n

Standard Deviation = Population Standard Deviation/ √n

Therefore, the mean and standard deviation of the sampling distribution of the sample mean for samples of size 4 is 35.2435.24 and 9.549.54 respectively.

The airplane's unit rate of speed in miles per hour is 450.

What is the rate of speed?

"Rate of speed" refers to "acceleration," or the rate at which your speed is varying. Units of "speed" are distances per time (eg miles per hour). Units for "rate of speed" are distance per time.

Here, we have

Given: Kelly flies a distance of 2,100 miles. the trip takes 4 2/3 hours.

Kelly flies at a distance of 2,100 miles

The time taken for the trip is 4 2/3 hours

The rate of speed can be calculated as follows

= 2,100 ÷ 4 2/3

= 2,100 ÷ 14/3

= 2100 × 3/14

= 150 × 3

= 450 miles per hour

Hence, the airplane's unit rate of speed in miles per hour is 450.

The graph of the system of inequalities is the one in the top left.

Here we want to graph the system of inequalities below:

x + y > −3

Now we can rewrite the two linear equations in the slope-intercept form to get:

y ≥ (1/3)x − 3

y > -x - 3

So we have two lines, both with an y-intercept at y = -3, one with positive slope (that will be a solid line, due to the symbol ≥) and other witha negative slope, which will be a dashed line.

In both lines, the shaded area is above the line.

We can start by using the following formula to find the original price:

Original price = Sale price / (1 - (Discount percentage / 100))

To use this formula, we need to convert the discount percentage from 26% to a decimal. We can do that by dividing 26 by 100.

Discount percentage as decimal = 26 / 100 = 0.26

Now we can use this value in the formula:

Original price = $469.16 / (1 - 0.26) = $469.16 / 0.74 = $630.22

So the original price of the television set was $630.22.

Given that the cost of adult ticket is $13.75  each

The cost of  children’s ticket is $9.50

Total cost of the movie tickets was $161.75

The total number of people are 13.

By given information we construct two equations

13.75x+9.5y=161.75

x=13-y

Now 13.75(13-y)+9.5y=161.75

178.75-13.75y+9.5y=161.75

178.75-4.25y=161.75

Subtract 178.75 on both sides

-4.25y=161.75-178.75

The long term rate is defined by r = 3/2.

Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive, where 0 indicates an impossible chance of occurrence and 1 denotes the certain outcome of an event. Joint probability refers to a statistical measure that determines the probability of two events occurring together and at the same point in time. Joint probability is the probability of event Y occurring at the same time that event X occurs. Hence, joint probability is a measure of two events happening at the same time and can only be applied to situations where more than one observation can occur at the same time.

A random variable with probability density function is f(x) = 2x, 0 <x<1.

Let Xi denote the life-time of the ith component , then Sn = ∑Xi represents the time of the nth failure. The long-term rate failures occur, is defined by

[tex]r = \lim_{n \to \infty} \frac{n}{S_n}[/tex]

Let Xi denote the ith component and understand that X1, X2,.., is a sequence of independent and similarly distributed random variables, with finite mean.

[tex]Mean = E[Xi] = \int\limits^0_1 {xf(x)} \, dx = \int\limits^0_1 {2x^{2} } \, dx = \frac{2}{3}[/tex]

So,

[tex]r = \lim_{n \to \infty} \frac{n}{S_n} = \frac{1}{Mean} = \frac{3}{2}[/tex]

After solving this equation we get x = 1 and y = 30.

An equation is a mathematical statement that describes the relationship between two or more variables. It is a statement that states the equality of two expressions. Equations can be used to describe anything from the motion of a pendulum to the growth of a population. They are used in all areas of mathematics, physics, and other sciences. Equations are written using symbols, such as = (equal to), > (greater than), and < (less than).

To solve this systems of equations, we need to use algebraic techniques. First, we need to rewrite the equations so they are in the same form. To do this, we will subtract x from both sides of the second equation, giving us:

y = x + 30

-x

y = 30

Now, we will subtract 30 from both sides of the equation, giving us:

y = 4x + 9

-30

y = 4x - 21

Now we will subtract 4x from both sides of the equation, giving us:

y = 4x - 21

-4x

y = -21

Finally, we will divide both sides by -21, giving us:

y = -21

-21

y = 1

This means that the solution to our system of equations is x = 1, y = 30.

To show our algebraic work on paper, we can rewrite the equations and perform each step as a mathematical operation:

y = 4x + 9

y = x + 30

y = x + 30 - x

y = 30

y = 4x + 9 - 30

y = 4x - 21

y = 4x - 21 - 4x

y = -21

y = -21 ÷ -21

y = 1
