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:
b) 43.3
Step-by-step explanation:
you use the trig ratio tangent because you are looking for the hypotenuse
so the equation should be <u>tan60</u> = <u>x </u>
1 25
and then you solve for that by cross multiplying and you get 43.3
The dimensions of the rectangular portion of the window should be 4 by 4.
To maximize area, we make the dimensions as close to congruent as possible. Since there will be 3 sides on the rectangular portion with a frame around them, we divide 12 by 3:
12/3 = 4
This means it should be 4 by 4.
