9.50/1 = x/6.2
(Cross multiply)
9.50*6.2 = 1x
58.9 = x
She will earn $58.90 if she works for 6 hours and 12 minutes
Explanation: since y is = to 6, 5x6 is 30 then + the remaining number, that concludes the answer to this equation as 32

Answer:
62.89% probability that there will be smeared names on at most 4 t-shirts
Step-by-step explanation:
For each shirt, there are only two possible outcomes. Either there will be smeared names, or there will not. The probability of there being smeared names on a shirt is independent of other shirts. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
4% of the shirts are smeared:
So 
What is the probability, if a sample of 100 t-shirts is checked, there will be smeared names on at most 4 t-shirts?
This is
when
. So








62.89% probability that there will be smeared names on at most 4 t-shirts
