What is the mean, median and mode for...45,50,55,55,55,60,60,60,65,65,70?

Answer:
Mean = 58.18
Median = 60
Modes = 55 and 60
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of numbers there are (ex. there are 11 numbers so divide the sum by 11).
The median is the middle number of a set. In this case, the middle number is easy to see because the # of numbers is odd, but if it was even, just find the average of the two middle numbers.
The mode is/are the most frequent number(s) in the set. In this set, the numbers that appear the most are 55 and 60.
Use the table of standardized normal cumulative function.
Look up the corresponding x' for the value z=0.9332: I found x'=0.8232 (approximately).
We know that x'=1.5x, so x = 0.8232/1.5 = 0.5488
The answer is no because she only got information from one group and she should get the input of other 7th graders
Answer:
see below
Step-by-step explanation:
i.
= √(3 + 4i)
= 2 + i
ii.
= √(-8 + 6i)
= √2(-4 + 3i)
iii.
= √(-40 - 42i)
= √-2(20 + 21i)
iv.
= √i
= √i
v.
= 
= 
Equal sides and equal angles
