Answer:
126 apples
Step-by-step explanation:
Let the number of apples picked by Mary=m
Cindy picks 6 times as many as Mary= 6Xm=6m
John picks 8 times as many as Mary= 8Xm=8m
Altogether they picked a total of 135 apples.
m+6m+8m=135
15m=135
m=135/15
m=9
We want to determine how many apples John and Cindy Picked.
John Picked 6m apples
Cindy Picked 8m apples
Their combined total= 6m+8m =14m
Since m=9
14m =14 X9 =126 apples
John and Cindy picked a total of 126 apples
Answer:
1) 0.30
2) 0.308
Step-by-step explanation:
1)
Interest Frequency
High 30
Medium 40
Low 30
Total frequency=30+40+30=100.
The relative frequency of student with high interest can be computed by dividing the frequency of high interest to the total frequency.
R.f of high interest=30/100=0.30
2)
Monthly Commission Frequencies
600-800 3
800-1000 7
1000-1200 11
1200-1400 22
1400-1600 40
1600-1800 24
1800-2000 9
2000-2200 4
Total frequency=3+7+11+22+40+24+9+4=120
The relative frequency of earning 1600 or more computed by dividing the frequency of earning 1600 or more to the total frequency.
R.f of earning more than 1600=24+9+4/120=37/120=0.308
