Supplementary = 180 so 3x+5+7x+6=180 10x+11=180 10x=169 x=16.9 3(16.9)+5 50.7+5 55.7 so 55.7 degrees
Answer: -1.55
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
Sample mean : 
The test statistic for the population mean is given by :-


Hence, the value of z statistic = -1.55
159.2/3.2=49.75
take 159.2 and divide it by 3.2 and you get 49.75
to check your answer you would take 159.2 divided by 49.75
159.2 divided by 49.75 = 3.2
3.2 is 49.75 percent of 159.2
1 dozen eggs = 12 eggs
1.35 / 12 = 0.1125.....so the unit cost = $ 0.11 (11 cents) per egg
<u>Given </u><u>:</u><u>-</u>
- A dealer sold a photocopy machine at Rs 4200 with 13% VAT to a retailer.
- The retailer added transportation cost of Rs 250 , profit Rs 300 and local tax Rs 150 and sold to consumer .
- Customer has to pay 13% VAT .
<u>To </u><u>Find </u><u>:</u><u>-</u>
- Amount to be paid by the customer .
<u>Sol</u><u>u</u><u>tion </u><u>:</u><u>-</u>
Here , according to the question ,
Therefore cost after adding VAT ,
Again the values added by the retailer before selling to customer ,
- Transport = Rs 250
- Profit = Rs 300
- Tax = Rs 150
Therefore total cost after adding these ,
Again Selling price after addition of 13% VAT ,
<u>Hence </u><u>the </u><u>amount </u><u>to </u><u>be </u><u>paid </u><u>by </u><u>the </u><u>customer </u><u>is </u><u>Rs </u><u>6</u><u>1</u><u>5</u><u>4</u><u> </u><u>.</u>
