• Sammy earned a total of $28.00.
• She picked twice as many pints of tomatoes as blueberries.
How many pints of blueberries did Sammy pick?
Answers
Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28

How to get population mean?
Suppose population is wide and you cannot evaluate all the population at once. Then you do sampling of large enough size randomly. The mean of that sample will be then the estimate for the mean that population will pertain.
What is experimental probability?
Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
where, is denoting experimental probability of occurrence of E.
Here, the customers are not all known to us, they are population.
But we have some data of the previous customer. Taking them as the sample, we have:
Experimental probability of an event from sample = Predicted probability for that event in population.
For this case, from the previous data, we have:
- 54 customers paid with cash
- 42 customers paid with debit card
- 153 customers paid with a credit card.
Total customers who paid = 153 + 42 + 54 = 249
Total customers who paid with cash = 54
Thus, if we take:
E = event that a customer pays with cash, then:
This is the probability deduced from the previous data that the next customer will pay with cash.
Thus, based on the number of customers from last week, the fraction is closest to the probability that the next customer will pay with cash is 54/249
