Answer:
Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.
Step-by-step explanation:
The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...
21/5 = 4.2
The four means are ...
-7 +4.2 = -2.8
-2.8 +4.2 = 1.4
1.4 +4.2 = 5.6
5.6 +4.2 = 9.8
5/9 (fraction simplified)
Answer:
5/8
Step-by-step explanation:
The probability of not getting blue can be found by dividing the number of sections that are not blue by the total number of sections.
P(not blue)= not blue / total
There are a total of 8 sections. 3 are blue, which leaves 5 that are not blue (1 yellow, 2 red and 2 green).
not blue= 5
total= 8
P ( not blue)= 5/8
This fraction cannot be reduced, therefore our answer is 5/8
Answer:
35°
Step-by-step explanation:
The central arc is equal to the arc that subtends it, then
arc AC = 75° and
BC = AC - AB = 75° - 40° = 35°
