To find the mean add all the numbers and dived by the number of numbers. So 15 + 23 + 14 + 17 + 21 = 90 / 5 = 18. The mean is 18.
Answer:
No Solution
Step-by-step explanation:
When you add your x's or subtract them onto the other side, and it equals 0 then there is no solution to the system
I think the first one is 36 and the second might be -71
<span>x/x+6 simplfiy to 1/6 = 0, So your answer is 0</span>
Answer:
≈ 35.91
Step-by-step explanation:
The law of sines lets you find the other sides:
DN/sin(M) = MN/sin(D) = DM/sin(N)
Angle D is 180° -75° -45° = 60°, so the remaining sides are ...
DN = sin(M)/sin(N)×DM = sin(75°)/sin(45°)×10 ≈ 13.66
MN = sin(D)/sin(N)×DM = sin(60°)/sin(45°)×10 ≈ 12.25
The perimeter is the sum of the side lengths, so is ...
10 + 13.66 +12.25 = 35.91
