Step-by-step explanation:
t=d/r. The distance is 15 the rate is 3m per seconds So you divide 15/3 =5. It will take him 5 seconds to walk 15 mi
Answer:
A) Not statistical /this question is answered by counting the number of days in March. This produces a single number. This number is not answered by collecting data that vary.
B) Not Statistical/ this question is answered by a single number. It is not answered by collecting data that vary.

D) statistical/ this question would be answered by collecting data, and there would be variability in that data
E) Not Statistical/ this question is answered by a single response. It is not answered by collecting data that vary.
F) not statistical/ this question would be answered by counting the bricks. This produces a single number. This question is not answered by collecting data that very
G) non-statistical/ there is only one temperature
So we have
h=hits
m=miss
h+m=10
gain 5 for every hit and lose 3 for every miss
so 5 times number of hit=points from hit
-3 times number of miss=points deducted from miss
add
5h-3m=18
so we have the equations
h+m=10
5h-3m=18
multiply first equation by 3
3h+3m=30
add to first equatio
3h+3m=30
<u>5h-3m=18 +</u>
8h+0m=48
8h=48
divide by 8
h=6
subsitute
h+m=10
6+m=10
subtract 6
m=4
6 hits
4 miss
