Which of the following statements is true?
This is a skewed-left distribution, because the mean is less than the median.
O This is a skewed-right distribution, because the mean is less than the median.
This is a skewed-left distribution, because the mean is greater than the median.
This is a skewed-right distribution, because the mean is greater than the median.
Because the mean is the same as the median, this distribution is roughly symmetric.
Answers
The correct option regarding the skewness of the distribution is given by:
This is a skewed-left distribution, because the mean is less than the median.
Given the mean and the median of a distribution, how we classify it's skewness?If the mean is greater than the median, the distribution is right-skewed, also called positively skewed. Otherwise, if the median is greater than the mean, the distribution is left-skewed, also called negatively skewed.
In this problem, we have that:
The mean is of 10.4.The median is of 13.4.The median is greater than the mean, hence the correct option is given by:
This is a skewed-left distribution, because the mean is less than the median.

The increase in the money supply that causes prices to rise and leads to inflation, loses purchasing power.
What is inflation?
Inflation refers to the persistent rise in the general prices of commodities in the economy over a period of time. If the prices of goods and services increase in an economy without an increase in income of people, it reduces the purchasing power of individuals.
This follows the law of demand which states that; the higher the price, the lower the quantity demanded; the lower the price, the higher the quantity demanded.

Which table has a constant of proportionality between y and x of 0.3?
Answers
Table C has a constant proportionality between y and x of 0.3.
A constant is an expression-unchanging value or number. It always has the same value.
In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.
The answer is the same as the one in the y column when you multiply the x number in table C by 0.3. The value that remains constant in the ratio is the proportionality constant. It is evident that table C is accurate because when you multiply each value in the x column by 0.3, the result is always the value in the y column.

C. Y = - ( x - 2 )^2 - 3
D. Y = 1/2 ( x + 2)^2 - 3
Answers
The quadratic equation is:
y = (x - 2)^2 - 3
So the correct option is A.
Which equation best represents the graph shown below?
The graph clearly is the graph of a quadratic equation, there we can see that:
The y-intercept is y = 1.
The vertex is (2, -3)
Remember that if we know that a quadratic equation has a vertex (h, k), then the equation can be written as:
y = a*(x - h)^2 + k
In this case, the vertex is (2, -3), replacing that we get:
y = a*(x - 2)^2 - 3
Now, we can find the value of a, the leading coefficient, by using the fact that the y-intercept is y = 1, evaluating in zero we should get:
1 = a*(0 - 2)^2 - 3
1 = a*4 - 3
1 + 3 = a*4
4/4 = a = 1
Then we conclude that the quadratic equation is:
y = (x - 2)^2 - 3
So the correct option is A.

How long will it take
you to
drive 135 miles at a speed of
45 miles per hour?
Answers
Answer: It takes 3 hours to drive 135 miles at a speed of 45 miles per hour.
Step-by-step explanation:
Define Time and Distance and Speed:
The length of distance traveled is proportional to the time taken to cover the distance, and we can represent this relationship as
Distance ∝ Time (Eq. 1)
The speed of any object is directly proportional to the distance traveled and inversely proportional to the time taken.
Speed ∝ Distance (Eq.2)
Speed∝1/Time (Eq.3)
Then, we can represent each parameter through the following equations:
Speed =Distance/Time
Distance=Speed × Time
Time =Distance/Speed
We can write:
Distance covered by driving: d=135 miles
Driving speed: s=45 mph
Recall the formula for the relationship of time, distance, and speed.
Time =Distance/Speed
Substitute d=135 and s=45 into the above formula, and simplify.
t=d/s
t=135/45
t=3 hours
Thus, it takes 3 hours to drive 135 miles at a speed of 45 miles per hour.
