Out of 100 people who attended a concert (pre-Corona obviously), 26 bought a teeshirt and 42 sat in the lawn section. Six students who sat in the lawn section also bought tee shirts. If a person who attended the concert was randomly selected, what is the probability that they bought a teeshirt if it is known that they did not sit in the lawn section? The first term in a geometric series is 5 and the common ratio is 2. Find the sum of the first 10 terms in the series.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
