Answer:
A
Step-by-step explanation:
6 friends
Mean - 10
Median - 9.5
Range - 14
3 friends watched 12, 13, and 18 movies.
Let's find the sum, this will help us find the total number of movies the other 3 friends watched.
12 + 13 + 18 = 43
The mean is all their movies added toether, divided by the number of friends.
m = number of movies the other friends watched.
(43 + m) / 6 = 10 Multiply each side by 6
43 + m = 10 * 6
43 + m = 60 Subtract 43 from each side
m = 60 - 43
m = 17
So we know the total movies the other friends watched is 3.
A. 4+6+7 = 17
B. 4+4+7 = 15
C. 5+8+9 = 22
D. 2+3+5 = 10
We know the answer is A.
We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.
4, 6, 7, 12, 13, 18
So 7+12 = 19
19/2 = 9.5
So we know for sure A is correct!
No.
The distance is |-5 -3| = 8 units. (Y-coordinates are the same, so the distance is measured entirely in the x-direction. Distance is non-negative.)
Step-by-step explanation:
Let x be the number. If the question is 2x-8, the answer is 10. If the question is 8-2x, the answer is -2. The answer is probably 10, though. The larger number is usually given first.
Answer:
angle i, which is D)
Notice that X and I are both in the middle of the triangles.
I think it’s b since it looks like a trapezoid
