Hello! I can help!
10:
a. 4-5 magazines interval contains the fewest data values.
b. There are 20 students in the class. 15 + 3 + 2 is 20.
c. Ignore the 6-7 interval and count the students from the others. 17/20 students read less than 6 magazines. 85% of students read less than 6 magazines.
d. You can’t exactly find the mean of the data, because you don’t know the exact number of how many each student read. The median would be in the range of 2-3, but you can’t find that either. You can’t find any of them without the exact numbers.
11. There were way more than 12% of songs that took 5-8 seconds to download. The error was getting the number of songs that took that long to download and putting it as a percentage. 12/36 songs took 5-8 seconds to download. 12/36 equals 1/3 (0.333) or simply 33%. The real answer is that 33% of the songs took 5-8 seconds to download.
Answer:
C. $2.70
If one pound of apples cost 3 times the amount of a pound of bananas, then a pound of apples costs; $2.70.
Remember
a/b times c/d=(ac)/(bd)
also remember add exponents with similar bases when mutiplying
x^m times x^n=x^(m+n)
(x^4)/3 times (x^2)/3=(x^4 times x^2)/(3*3)=(x^(4+2))/9=(x^6)/9
answer is (x^6)/9
