Step-by-step explanation:
why is the mean of the set of data is always greater than it's median?
Answer:
One of the basic tenets of statistics that every student learns in about the second week of intro stats is that in a skewed distribution, the mean is closer to the tail in a skewed distribution. So in a right skewed distribution (the tail points right on the number line), the mean is higher than the median.
Step-by-step explanation:
The distribution is said to be right-skewed. In such a distribution, usually (but not always) the mean is greater than the median, or equivalently, the mean is greater than the mode; in which case the skewness is greater than zero.

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May it cost her $420 to drive 500 mi and in June it cost her $444 to drive 620 mi. (a) Express the monthly cost C as a function of the distance driven d, assuming that a linear relationship gives a suitable model. C(d)
Answer:
[tex]C(d) = \frac{1}{5}d + 320[/tex]
Step-by-step explanation:
Given
[tex]d \to miles[/tex]
[tex]C \to cost[/tex]
So:
[tex](d_1,C_1) = (500,420)[/tex] --- May
[tex](d_2,C_2) = (620,444)[/tex] --- June
Required
Express as a function
Start by calculating the slope (m)
[tex]m = \frac{\triangle C}{\triangle d}[/tex]
[tex]m = \frac{444-420}{620-500}[/tex]
[tex]m = \frac{24}{120}[/tex]
Simplify
[tex]m = \frac{1}{5}[/tex]
The equation is:
[tex]C(d) = m(d - d_1) +C_1[/tex]
[tex]C(d) = \frac{1}{5}(d - 500) +420[/tex]
[tex]C(d) = \frac{1}{5}d - 100 +420[/tex]
Take LCM
[tex]C(d) = \frac{1}{5}d + 320[/tex]

The relationship between the actual air temperature x (in degrees Fahrenheit) and the temperature y adjust for wind chill (in degrees Fahrenheit, given a 20 mph wind) is given by the following formula:
y= -22 + 1.4x
Estimate the actual temperature if the temperature adjusted for wind chill is -15 degrees Fahrenheit.
The actual temperature is 5 degrees Fahrenheit if the temperature adjusted for wind chill is -15 degrees Fahrenheit.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
We have the relationship between the actual air temperature x (in degrees Fahrenheit) and the temperature y adjust for wind chill (in degrees Fahrenheit, given by 20 mph wind) is given as:
y = -22 + 1.4x
When.
The temperature adjusted for wind chill, y = -15 degrees Fahrenheit
Put this value in the given linear equation, we get:
-15 = -22 + 1.4x
-15 + 22 = 1.4x (add 22 on both sides)
7 = 1.4x
x = 5 degrees Fahrenheit (divide by 1.4 on both sides)
Thus, the actual temperature is 5 degrees Fahrenheit if the temperature adjusted for wind chill is -15 degrees Fahrenheit.

At a basketball game, a vender sold a combined total of 200 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
Answer:
50 hot dogs
150 sodas
Step-by-step explanation:
set up a system of equations where 'h' = # hot dogs sold and '3h' = # sodas sold
h + s = 200
s = 3h
h + 3h = 200
4h = 200
h = 50
s = 200-50 or 150

The population of a small town in central Florida has shown a linear decline in the years 2001-2012. In 2001 the population was 22200 people. In 2012 it was 13950 people.
A) Write a linear equation expressing the population of the town, P , as a function of t , the number of years since 2001. Include the entire equation as your answer. Answer: _________________
B) If the town is still experiencing a linear decline, what will the population be in 2014?
Answer:
Step-by-step explanation:
First of all, to keep our numbers manageable, we are going to let year 2001 = 0 so year 2012 = 11. The coordinates that result from these years/population numbers are (0, 22200) and (11, 13950). Since this linear, we can plug those 2 coordinate pairs into the slope equation to find the rate at which the population is decreasing in people per year:
[tex]m=\frac{13950-22200}{11-0}=\frac{-8250}{11}=-750\frac{people}{year}[/tex] That means that the town is losing people at the rate of 750 per year. We can use that slop along with one of the coordinate points to write the linear equation representing this situation:
[tex]y-22200=-750(x-0)[/tex] and
y = -750x + 22200. That answers part A.
Now for B we need to find y when x = 13 (remember we let year 2001 = 0, so year 2014 = 13):
y = -750(13) + 22200 so
y = 12450 people in the year 2014
A new medical test has been designed to detect the presence of the mysterious Brainlesserian disease. Among those who have the disease, the probability that the disease will be detected by the new test is 0.7. However, the probability that the test will erroneously indicate the presence of the disease in those who do not actually have it is 0.02. It is estimated that 20 % of the population who take this test have the disease. If the test administered to an individual is positive, what is the probability that the person actually has the disease
Answer:
0.8974 = 89.74% probability that the person actually has the disease.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive test.
Event B: Has the disease.
Probability of a positive test:
0.7 of 0.2(has the disease).
0.02 of 100 - 20 = 80%(does not have the disease). Thus:
[tex]P(A) = 0.7*0.2 + 0.02*0.8 = 0.156[/tex]
Probability of a positive test and having the disease:
0.7 of 0.2. So
[tex]P(A \cap B) = 0.7*0.2 = 0.14[/tex]
What is the probability that the person actually has the disease?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.14}{0.156} = 0.8974[/tex]
0.8974 = 89.74% probability that the person actually has the disease.

[Subtraction Property of Equality] Subtract 4x on both sides: 3x - 18 = 21[Addition Property of Equality] Add 18 on both sides: 3x = 39[Division Property of Equality] Divide 3 on both sides: x = 13Answer:
x = 13
Step-by-step explanation:
7 x - 18 = 4 x + 21
Subtract 4x on both side
7x - 4 x - 18 = 4x - 4x + 21
3 x - 18 = 21
Add 18 on each side
3 x - 18 + 18 = 21 + 18
3 x = 39
Divided each side by 3
3 x / 3 = 39 / 3
x = 13

Over a season in a women's basketball league Jackson scored 38 more points than the second-highest scorer, Leslie. Together, Jackson and Leslie scored 1134 points during the season. How many points did each player score over the course of the season?
Answer:
leslie will hace 587 score and
jackson =587+31= 618
Step-by-step explanation:
1134 -31/2 = leslie
leslie + 31 = 618
Answer:
see below
Step-by-step explanation: 6 24 10 18
Leslie = x points
Jackson scored 38 more points than Leslie Jackson = x + 38 points
Together, Jackson and Leslie scored 1134 Sum of both scores
Leslie + Jackson = 1134
x + x + 38 = 1134 solve for x Leslie's number of points
2x + 38 = 1134
2x + 38 - 38 = 1134 -38
2x = 1096
2x/2 = 1096 / 1
x = 1096 /2
x = 548 Leslie points
Jackson = Leslie's points + 38 points
= 548 + 38
Jackson's points = 586 points
Solve the inequality 31<3x + 4
Answer:
x > 9
Step-by-step explanation:
31 < 3x + 4
Treat the < sign the same way you do with =
So first minus 4
31 < 3x + 4
-4 -4
27 < 3x
Divide both sides by 3
9 < x
If you want x on the other side just flip the symbol
x > 9

NO LINKS NO FILES. After you add 3 to both sides of the equation 27 = m/6 - 3, what should you do next?
Answer:
Multiply each side by 6
Step-by-step explanation:
27 = m/6 - 3
Add 3 to each side
27+3 = m/6 - 3+3
30 = m/6
Multiply each side by 6
30*6 = m/6*6
180 = m

% compounded continuously. After 17 years, how much more money would Serenity have in her account than Avery, to the nearest dollar?
After 17 years, Serenity has $778 more than Avery
The formula for calculating the compound amount is expressed according to the formula;
[tex]A=P(1+\frac{r}{n} )^{nt}\\[/tex]
For Avery;
P = $3,800
rate = 5 1/2 % = 0.055
time = 17 years
n = 12 (monthly compounding)
Substitute into the formula to have:
[tex]A=3800(1+\frac{0.055}{12} )^{12(17)}\\A=3800(1+0.00458)^{204}\\A=3800(1.00458)^{204}\\A=3800(2.5401)\\A = \$9,652.22[/tex]
Hence the amount that will be in Avery's account after 17years is $9,652
For Serenity;
P = $3,800
rate = 6 1/8 % = 0.06125
time = 17 years
n = 1 (continuous compounding)
Substitute into the formula to have:
[tex]A=3800(1+\frac{0.06125}{1} )^{1(17)}\\A=3800(1+0.06125)^{17}\\A=3800(1.06125)^{17}\\A=3800(2.7473)\\A = \$10,439.62[/tex]
Hence the amount that will be in Serenity's account after 17years is $10,430.
Amount Serenity have more than Avery = $10,430 - $9652 = $778
