the amount they paid includes the price of the two smoothies and tip
since the friends are splitting the bill in 2, then each friend pays only half the amount
each friend pays $ 3.60 each
so the total amount they both paid is 3.60 x 2 = $ 7.20
the cost of one smoothie - $3
therefore the cost of the 2 smoothies - 3 x 2 = $ 6
so they paid 7.20 but the bill was only 6 dollars
so the difference in the 2 amounts is the value of the tip they left
tip = 7.20 - 6 = 1.20
so the percentage of the tip is - tip amount / value of the bill x 100 %
percentage = 1.20 / 6.0 x 100 % = 20 %
they left 20 % of the bill as a tip
Answer:
We can conclude that the battery life is greater than the 32 hour claim.
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the statistic, 
is the mean, 
is the standard deviation and n is the size of the sample.
In this problem, we have that:
So
We need to find the probability of finding a mean time greater than 37.8. If it is 5% of smaller(alpha = 0.05.), we can conclude that the battery life is greater than the 32 hour claim.
Probability of finding a mean time greater than 37.8
1 subtracted by the pvalue of z = t = 2.46.
z = 2.46 has a pvalue of 0.9931
1 - 0.9931 = 0.0069 < 0.05
So we can conclude that the battery life is greater than the 32 hour claim.

Given:
<span>march 12 - Klein company, inc. sold merchandise in the amount of $7,800 to Babson company, with credit terms of 2/10, n/30
</span><span>march 15 - Babson returns some of the merchandise. the selling price of the merchandise is $600
march 20 - Babson pays the invoice and takes the appropriate discount.
Since March 20 is still within the 10-day discount from date of purchase, Babson is entitled to 2% discount.
7,800 - 600 = 7,200 sales invoice
7,200 * 2% = 144 sales discount
7,200 - 144 = 7,056 net sales
Babson will pay the amount of $7,056</span>
