A salesperson receives step commission on sales calculated as follows:
a. 8% on first $1000
b. 12% next $2000
C. 20% on sales above $3000
2. Calculate the salesperson's earning in one week if their sales were as follows:
Monday $1500.00
Tuesday $3000.00
Wednesday $ 970.00
Thursday $4563.81
Friday $2760.42
Answer:
$2278.846
Step-by-step explanation:
Given the following commision steps :
8% on first $1000;
12% next $2000;
20% on sales above $3000
Recorded sales for a week :
Monday $1500.00
Tuesday $3000.00
Wednesday $ 970.00
Thursday $4563.81
Friday $2760.42
This assu es that commision is calculated after weekly sales:
Total:
(1500 + 3000 + 970 + 4563.81 + 2760.42)
= $12794.23
8% on first $1000
0.08 × $1000 = $80
12% of $2000 = $240
20% of $(12794.23 - 3000)
= 0.2 × 9794.23
= 1958.846
Total commision for the week :
$(80 + 240 + 1958.846)
= $2278.846

Answer:
Step-by-step explanation:
1.Let the number be x.
2.To find one-third of a number, divide the number by 3 ,
3. x÷3.
The required simplified value of the expression 13 - 1/3(11 - 5) is 11.
Given that,
To evaluate: 13 - 1/3 (11-5)
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
= 13 - 1 / 3( 11 - 5 )
Solving the parenthesis first (11 - 5) = 6
= 13 - 1 / 3 * 6
Following the PEMDAS rule, multiply between 1/3 and 6 = 2
= 13 - 2
Subtraction
= 11
Thus, the required simplified value of the expression 13 - 1/3(11 - 5) is 11.

Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations? A. Some of these data have vastly different centers, and the median and interquartile range provide more reliable information in these circumstances. B. These data are fairly symmetric and do not have outliers, and the median and interquartile range provide more reliable information in these circumstances. C. Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers. D. Some of these data have outliers and/or are skewed, and the median and interquartile range amplify the effects of outliers and skewness.
Answer:Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers.
Step-by-step explanation:
Outliers often characterize a lot of data. Outliers are extreme values which have obvious impact on the value of the standard deviation of a given distribution.
However, the median and interquartile range are resistant to outliers hence they can be used even in the presence of outliers in the distribution.
The best for comparing the medians and interquartile range is the first option
What are outliers?
Outliers refer to the attribute of a lot of data. It is considered to be an extreme value that should have an impact on the value of the standard deviation of a given distribution. But, the median and interquartile range should be resistant to outliers.

if you could can you give it to me now I'm in a hurry
Answer:
3 2/3 divided by 3 4/5 is [tex]\frac{55}{57}[/tex]
Step-by-step explanation:
Operations With Fractions
Let's divide 3 2/3 by 3 4/5. Both fractions are in mixed format, so we have to write them as an improper fraction:
[tex]\displaystyle 3\frac{2}{3}=3+\frac{2}{3}=\frac{9+2}{3}=\frac{11}{3}[/tex]
[tex]\displaystyle 3\frac{4}{5}=3+\frac{4}{5}=\frac{15+4}{5}=\frac{19}{5}[/tex]
We must divide [tex]\frac{11}{3}[/tex] by [tex]\frac{19}{5}[/tex]
To make it simple, we just multiply the first fraction by the reciprocal of the second fraction:
[tex]\displaystyle \frac{\frac{11}{3} }{ \frac{19}{5}}=\frac{11}{3} * \frac{5}{19}=\frac{55}{57}[/tex]
3 2/3 divided by 3 4/5 is [tex]\frac{55}{57}[/tex]

At the end of the day the stock market goes up 9012" role="presentation">90129012 90 1 2 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day? The total change in the stock market is points.Points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
124.51%Step-by-step explanation:
In this problem, we are expected to solve for the percentage change, given the opening point and the closing point
given that the low is 4014
and the high is 9012
the formula to calculate the percentage change is given as
%change= (high-low)/low*100
substituting our given data we have
%change= (9012-4014)/4014*100
%change= (4998)/4014*100
%change= (1.2451)*100
%change= 124.51%
The total change in the stock market from the beginning of the day to the end of the day is 124.51%

Elephants are born with tusks, and their tusks grow 4 inches a year. A 1-
year old elephant's tusk measured 5 inches. Write a linear equation that
represents the situation. How long will the elephant's tusk be at 6-years
old?
The linear equation that represents the given situation is :
y = 4x + 1 and the elephant's tusk at 6-years old will be 25 inches.
represents the situation.
What is linear variation or linear equation?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases.Mathematically, we can write → y = Kx.The above equation is also called a linear equation or more elaborately the equation of a straight line. The general equation of a straight line is → y = mx + c.Given is that Elephants are born with tusks, and their tusks grow 4 inches a year. A 1 - year old elephant's tusk measured 5 inches.
Since the tusks grow 4 inches a year, we can write -
y = 4x + c
{y} - length of tusk
{x} - number of years
Now, at (1, 5) -
5 = 4 x 1 + c
c = 5 - 4
c = 1
So, the linear equation that represents the given situation is -
y = 4x + 1
For {x} = 6, we can write -
y = 4 x 6 + 1
y = 25 inches
Therefore, the linear equation that represents the given situation is :
y = 4x + 1 and the elephant's tusk at 6-years old will be 25 inches.
represents the situation.

Which expression is equivalent to (3 + 5i)2?
0 -16 + 301
O 6 + 341
0 -16 - 341
O 16 + 301
expression that equivalent to (3 + 5i)² is -16 + 30i.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, an expression ( 3 + 5i)²
Where, "i" is iota that has the value of √-1
Thus, Simplification of the given Expression will be:
=> ( 3 + 5i)²
=>( 3 + 5i)( 3 + 5i)
Using PEMDAS
=> 9 + 15i +15i +5i * 5i
Since i *i = -1
=> 9 + 30i + 25 * -1
=> -16 + 30i
therefore, -16 + 30i expression is equivalent to (3 + 5i)².

Consider a normally distributed data set with a mean of 75 and a standard deviation of 5. If
one of the recorded values is 87, how many standard deviations away from the mean is this
value?
Answer:
2.4
Step-by-step explanation:
To obtain the z value, subtract the mean (75) from the given value (87) and divide the result by the standard deviation (5). The answer is 2.4.
The standard deviations away from the mean is the recorded value 87 when a mean of 75 and a standard deviation of 5 is 2.4.
What is normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean. The mean of the data is the average value of the given data.
The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
Consider a normally distributed data set with a mean μ of 75 and a standard deviation σ of 5.
One of the recorded values X is 87. To find the away value, we have to find the z score using the following formula,
[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]
Here, X is the sample size, μ is the mean and σ is the standard deviation of the data. Put the values,
[tex]Z=\dfrac{87-75}{5}\\Z=2.4[/tex]
Thus, the standard deviations away from the mean is the recorded value 87 when a mean of 75 and a standard deviation of 5 is 2.4.
