Answer:
No of clothes to be sold to gain $6000=20,000
Given:
Base salary = $4000
Rate of Commission = 10%
Amount salesman wants to earn in May = $6000
To find:
How much clothing units needed to be sold in order gain $6000 in may
<u>Step by Step Explanation:
</u>
Solution;
According to the formula;
=6000 - 4000 = 2000
Also we know,
Let the commission amount be x
x=20,000
Result:
Hence, the clothing to be sold in order to earn $6000 is 20,000 units.
step 1 has incorrect justification
Answer:
The 95% confidence interval based on this sample is =
[6.41, 7.79]
Step-by-step explanation:
The formula for Confidence Interval =
Mean ± z × standard deviation/√n
Sample mean = 7.1 hours
Standard deviation = 5 hours
n = 200 students
z = 95% confidence interval z score
= 1.96
C.I = 7.1 ± 1.96 × 5/√200
C.I = 7.1 ± 0.693
Hence, Confidence Interval
= 7.1 - 0.693
= 6.407
Approximately = 6.41
= 7.1 + 0.693
= 7.793
Approximately = 7.79
Therefore, the 95% confidence interval based on this sample is
[6.41, 7.79]
Answer:
y= 10x-38
Step-by-step explanation:
Equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Given that m=10,
y= 10x +c
Now substitute the coordinates into the equation.
When y=12, x=5,
12= 10(5) +c
12= 50 +c
c= 12 -50
c= -38
Thus the equation of the line is y= 10x -38
Answer:
V≈146.57ft^3
Step-by-step explanation:
V=πr^2·h/3 since d is 14.4, we would divide it by 2 to find the radius which is 7.2
so V= π(7.2)^2· (2.7)/3
V≈146.57ft^3
It would be greatly appreciated if you gave me the brainlest
