D. it is even
In the example statement, a hypothesis is being made of whether the number is a multiple of 2. The hypothesis is that it is even. And there's your answer.
To get the speed of growth of plant we proceed as follows;
rate=(distance)/(time taken)
distance( length) of growth of the plant in 14 days is 3.6 m.
1 day=86400 sec
14 days=86400x14=1,209,600 sec
1 m=1000000 micrometer
3.6 m=3600000 micrometer
thus the rate of growth will be:
3600000/1209600
=2.9762 micrometers per second
Point A is (-3,1), C is (4,4)
MidPoint is ( (x1+x2)/2, (y1+y2)/2)
MP is (0.5, 2.5)
Subtract 14 from both sides
4b=8
Divide both sides by 4
b=2
Final answer: b=2
Jeff
3/4 miles in 10 minutes
times 6
9/2 miles in 1 hour
Barbara
13/16 mile in 15 minutes
times 4
13/4 mile in 1 hour. As a result, Jeff is the faster walker and he will wake 5/4 more miles in 1 hour. Hope it help!
