Answer:
James
Step-by-step explanation:
James rate:
2x + 2 = 4
2x = 2
x = 1 hour
Rate = distance/time = 4/1 = 4 miles per hour
Craig's rate = 1/2 = 0.5 miles per hour
James is faster
Is this rearranging of equation??
-n+sx=n-a
sx=2n-a
x=2n-a/s
In normal distribution, 68% of the values are within +_ 1 SD. That leaves 32% outside that range. Thus, 32 people with greater than 13, 100 people greater than 14 (200*0.68/2+32)
Crosssection= 1.7mx2=3.4
2x3=6x3=18
3.4+18=21.4
The first one is 0.5 the second one is 125 and the third one is 0.2 and the fourth one is 5 I think those are the answers
