To find the mean, you need to find the average. The equation that I used was 61(1)+64(3)+67(5)+70(6)+73(5) and then divided that total by the total number of 20.
The answer would be D) 68.5
Answer:
No solution
Step-by-step explanation:
3(x-3)+5=3x+1+4
3(x-3)+5=3x+5
3x-9+5=3x+5
3x-4=3x+5
+4 +4
3x=3x+9
-3x -3x
0≠9
Hope this helps!
Answer:
1) Clare's stone hit first.
2) 1 seconds.
3) Same maximum height for both.
4) 9 feet
Part A:
h = (-16t -8)(t - 1)
When the stone hits the water, the height will be 0
⇒ (-16t - 8)(t - 1) = 0
<u>set to zero</u>
⇒ -16t - 8 = 0, t - 1 = 0
<u>simplify</u>
⇒ t = -1/2, t = 1
So, time was 1 seconds for Clare and 1.25 seconds or Lin. Clare's hit first.
Part B:
For Lin's stone: maximum height: 9 feet.
For Clare stone: (-16(0.25) - 8)((0.25) - 1) = 9 feet
No both stone reached the maximum height of 9 feet.
