Answer:
Step-by-step explanation:
Hello!
You have da data for the variables:
X: Number of the day after the opening of Jackson's business.
Y: Number of personal recommendations given by customers of Jackson's business.
Since Jackson's business relies on his customers for advertisement, it is to be expected that the more it is recommended, the more will the business grow.
If this is so then as time passes by, the number of customers and recommendations should increase.
I've made a scatterplot between the two variables, see attachment.
As shown in the scatterplot it seems to be a positive association between these two variables, meaning, when the days pass by, the number of personal recommendations increases.
I hope this helps!
Answer:
2× +46 + 3×-6 =90
sx+40=90
5X=90-40
x=50/5
X=10
frist angle= 2×10+46= 66
secnd angle= 90- 66 = 2 4
The mean of these workers is total salary/number of workers=(5*25000+3*27000+1*34000)/(5+3+1)=26667, approximately. The standard deviation formula is \sqrt(1/n*sum of (x_i-mu)^2) from 1 to n. Plug in n=9, mu=26667, the standard deviation is 2915 dollars approximately.
Answer:
The cost of goods sold per tie was $22
Step-by-step explanation:
The list of all associated cost in a month on the job 1041 is
- Direct materials - $54,800
- Direct Labour - $19,200
- Selling $ Shipping Costs - $28,000
- Overhead costs - $25 per MH × 320MHs = $8,000
The total cost of production of the ties can then be obtained by adding all associated costs;
$54,800 + $19,200 + $28,000 + $8,000 = $110,000
Total units of ties made from Job 1041 is 5,000
Therefore,
Cost per unit tie = $22
