Answer:
$6500
Step-by-step explanation:
Given data
Monthly Earnings= $4500
Commission= 4%
Sales= $50000
Let us find the amount of the commission
=4/100*50000
=0.04*50000
= $2000
Since the monthly earning is $4500, hence the total earning is
=2000+4500
=$6500

What is the slope y =- 5x 3?
Parallel lines are two straight lines that never cross. For this to happen, the lines have to have the same slope.
In this case, the equation given is in what's called "slope-intersect" form. The general form of the slope intercept formula is y=mx + b where m is the slope of the line and b is the point on the Y-axis where the line crosses.
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer.
Slope-Intercept Form:
When we're given a linear equation we can immediately see if it's in the slope-intercept form if it follows the format y=mx+b. As long as y does not have a coefficient the slope and y-intercept are the values of m and b.

We may deduce from the contour map that the estimates of the given functions are;
fx(2, 1) = 10
fy(2, 1) = 3
What exactly does the term "counter map" mean?The geographic mapping used as a form of activism against prevailing power systems is known as counter-mapping.
How Do You Interpret Contour Lines on a Map?Contour lines are described as the faint lines drawn on a map that link places of equal height above sea level. This indicates that even if you followed a contour line physically, the elevation (height of the land) would stay constant.
According to the contour map, the contour lines indicate that the coordinate (2, 1) in the x-direction has a value of 10.
Therefore; fx(2, 1) = 10
Using the same idea, we can deduce from the attached contour map that the coordinate (2, 1) in the y-direction will have a value between 0 and 6. Therefore;
Average = (0 + 6) divided by 2 = 3
Thus; fy(2, 1) = 3

in a certain large population of adults, the distribution of iq scores is strongly left-skewed with a mean of 122 and a standard deviation of 5. suppose 200 adults are randomly selected from this population for a market research study. the distribution of the sample mean of iq scores is (a) left-skewed with mean 122 and standard deviation 0.35. (b) exactly normal with mean 122 and standard deviation 5. (c) exactly normal with mean 122 and standard deviation 0.35. (d) approximately normal with mean 122 and standard deviation 5. (e) approximately normal with mean 122 and standard deviation 0.35.
The correct answer is e) approximately normal with a mean 122 and standard deviation 0.35.
In this case, the distribution of the sample mean of IQ scores will be approximately normal because the sample size of 200 is sufficiently large. This is known as the Central Limit Theorem, which states that the distribution of the sample mean will be approximately normal as long as the sample size is large enough, regardless of the shape of the distribution of the population.
The mean of the sample mean distribution will be 122, which is the same as the mean of the population. The standard deviation of the sample mean distribution will be smaller than the standard deviation of the population because it is calculated using the sample size rather than the population size.

Can this be a biconditional statement and still be true? : “If a polygon is a square, then it has four sides.”
No, the biconditional statement isn't true because It's not necessary that if a polygon has four sides, then It will be a square.
What is Biconditional statement?
A statement that combines a conditional statement with its opposite is known as a biconditional statement. So, if and only if the other conditional is also true, the first conditional is true.
Let's elaborate the statement, “If a polygon is a square, then it has four sides.”
We know that a square has four equal sides and So, if a polygon is a square, it must have four equal sides which states that the given statement is true.
But, if we see its converse, "If a polygon has four sides, then it is a square". It is not necessary that the polygon will be a square.
eg. A parallelogram and rectangle also have four sides, So it could either be a parallelogram, rectangle or a square.

Instead of being a property of the function itself, piecewise definition is a means to express the function.
When the domain may be divided into intervals on which the property holds, the phrase "property holding piecewise for a function" is used, which is separate but related. This is a characteristic of the function itself, as opposed to the idea mentioned above.

Suppose we select two distinct balls
Then we have the following possibilities of selecting two balls
(2,2), (2,2) ............, i.e. 2 ways to get a sum of 4...............(2+2 = 4 and 2+2 = 4)

(6,5), (5,6) , i.e. 2 ways to get a sum of 11...............(5+6 = 11 and 6+5 = 11)
total number of possible outcomes = 2(for a sum of 4) + 4(for a sum of 7) + 4(for a sum of 8) + 2 (for a sum of 11)
= 2 + 4 + 4+2
= 12
So, P(getting a sum of 4) = (number of ways to get a sum of 4)/total number = 2/12
similarly,
P(getting a sum of 7) = (number of ways to get a sum of 7)/total number = 4/12
P(getting a sum of 8) = (number of ways to get a sum of 8)/total number = 4/12
P(getting a sum of 11) = (number of ways to get a sum of 11)/total number = 2/12
We know that expected value E[x] = sum of all individual sum values by their respective probability
= 4*(2/12) +7*(4/12) +8*(4/12) +11*(2/12)

As in the question, it is mentioned that we have to take the number m as a variable.
So, we are going to use this ‘m’ for solving this question.
Let the number be m.
Then, twice of m will be similar to 2 times m or m multiplied by 2.
Therefore, twice m will be 2m.
Now, the question is saying that 6 more than twice m.
“6 more than” means 6 is added to that specific number.
Hence, 6 more than that number which is twice of m will be 2m+6.

PercentageThis is the expression of a ratio or fraction in percentage form. This is done by multiplying a ratio by 100.
The original advertising budget is $81,000 and they plan to increase it by 5%.
Let's calculate the 5% increase in the budget.
5% of 81000 =
5 / 100 = x / 81000
0.05 = x / 81000
x = 81000 * 0.05
x = 4050

The simplified form of the expression, from the given options, is 2³.
A business recently upgraded a conference TV they had in their conference room. Originally the TV was 32 inches (across the diagonal) and had a perimeter of 87.16 inches. The new TV is 66 inches across the diagonal. Since the new TV will be recessed in the wall, it will need trim put on the border. What is the perimeter of the new TV? Round your answer to two decimal places.
The perimeter of the new TV will be 179.77 inches.
How to calculate the perimeter?From the information, the TV was 32 inches (across the diagonal) and had a perimeter of 87.16 inches and the new TV is 66 inches across the diagonal.
It should be noted that the perimeter simply means the total length of the boundary of the object. This will be calculated thus:
= (66 × 87.16) / 32
= 5752.56 / 32
= 179.77 inches.
In conclusion, the perimeter is 179.77 inches.
