Answer:
a=2
b=10.5
c=4
d=17.5
Step-by-step explanation:
so 3.5 miles per hour and the columns are miles and then hours
so an equation can be 3.5 (mi/hr) * t (time) = distance
so for a): 3.5*t=7
t=2
b) 3.5*3=distance
distance is 10.5
c) 3.5*t=14
t=4
d) 3.5*5=d
d= 17.5
Answer:
Below.
Step-by-step explanation:
12. That is a semicircle
The central angle is 180 degrees.
Experimental probability is the ratio of number of times the event is occurring to the total number of the trials of the experiment. This implies that it is a ratio of the number of times an event is occurring to the total number of times that the activity has been repeated. Thus we shall use the formula:
Experimental probability=(# of occurrence of the event)/(total # of trials made)
=6/20
=3/10
Answer: 3/10
Answer:
c. mean: 9/20, median: 2/5, mode: 3/4
Step-by-step explanation:
3/4
,
2/5
,
1/10
,
3/4
,
1/4
It is best to order this list from low to high
low end, 1/10, 1/4, 2/5, 3/4, 3/4
middle is 2/5
mode = 3/4 the most repeated
mean: [2/20 + 5/20 + 8/20 + 15/20 + 15/20] * (1/5)= 45/20 *(1/5)
Answer:
3/8
Step-by-step explanation:
1/4 = 2/8
1/8 + 2/8= 3/8
3/8 is simplified
