Answer:
The commission rate is of 12%.
Step-by-step explanation:
Commission rate:
The commission rate is given by the commission value multiplied by 100% and divided by the value of merchandise sold.
In this question:
$252 in commission for selling $2100 in merchandise. So
252*100%/2100 = 12%
The commission rate is of 12%.
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
Answer:
The answer is

Step-by-step explanation:
First you have to find the radius of sphere by dividing diameter by 2 :

Let diameter = 14,


Next you have to use the volume of sphere formula :

Let r = 7,



Answer:
35
Step-by-step explanation:
write 5 in N's place
5^2+2×5×1
25+10
35
Part A:
For this case we have that the relationship between time and radius is linear.
We observe that for each day that passes, the radius increases two centimeters.
Therefore, the linear function is:
y = 2x
Since the linear function is exact, the correlation coefficient is:
r = 1
Answer:
r = 1
Part B:
As the linear function is:
y = 2x
So for days 1 and 2 the slope of the graph is:
m = 2
It means that the radius increases 2 centimeters per day.
Answer:
m = 2
Part C:
The data represents a correlation.
This is because the data follows a linear trend.
The radius always grows 2 centimeters for each day that passes.
Answer:
Correlation.
