The mean of the sample given by 44,22,11,17,21 will be given by:
\mu= \frac{\Sigma  x_i}{n}
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23

Is the triangle an equilateral triangle
solong [7]
It is not an equilateral triangle. To prove this, you must solve for x. I found x by setting 2x+5.2 = 3x+1.2 to get x=4. Then I plugged 4 into equation to see if they were equal. 2(4)+5.2= 13.2 and 3(4)+1.3=13.2 but 2(4)+6.2=14.2. This allows us to conclude that the triangle is not equilateral because all of the sides are NOT congruent. Hope that helped:))

Jackie's mail route has 350 mailboxes. She can deliver mail to 50 mailboxes per hour. If she has delivered mail to 150 mailboxes
Lyrx [107]
Okay, Jackie starts with 350 mailboxes, but has delivered to 150, so she only has to deliver to 200 more. She can deliver to 50 mailboxes per hour. So 200/50 = 4. The answer is 4 hours.
