You mesure it with a contracter
Answer:
Correct options are A,B,D:
- The sample needs to be random, but we don't know if it is.
- The actual count of community residents who received the concert brochure by mail is too small.
- n(1 minus p‐hat) is not greater than 10.
Step-by-step explanation:
Concert marketing: The college’s performing arts center wanted to investigate why ticket sales for the upcoming season significantly decreased from last year’s sales. The marketing staff collected data from a survey of community residents. Out of the 110 people surveyed, only 7 received the concert brochure in the mail.
Answer: Each dozen of chocolate chip cookies costs $1.50/dozen. So if you sell C dozens of them, you win C*$1.50 dollars, where C is a positive integer number. Similar case for the lemon ones, the baker will win L*$1.00 dollars if he sells L dozens of them ( where L is a positive integer), the total charge is the sum of both parts; T = L*$1.00 + C*$1.50.

Since the numerators are the same, the smaller the denominators, the greater the fraction is.

Method 2

Lets change all to the same denominators
Now that all the denominators are the same, we can arrange the fractions by comparing the numerators. The bigger the numerators, the greater the fraction.
Arranging from the least to the greatest
The exponent indicates how many times the base is used as a factor.
