Step-by-step explanation:
<em>Refer to attached</em>
- Height of plants (h) >> Frequency >> Midpoint >> Frequency x midpoint
- 0 <h < 10 >> 1 >> 5 >> 5
- 10 <h < 20 >> 4 >> 15 >> 60
- 20 <h < 30 >> 7 >> 25 >> 175
- 30 <h < 40 >> 2 >> 35 >> 70
- 40 <h < 50 >> 3 >> 45 >> 135
- 50 <h < 60 >> 3 >> 55 >> 165
Sum of frequencies = 20
Sum of frequency x midpoint product = 610
<u>Mean height </u>

Hey there! I'm happy to help!
We see that Rosy uses 1/4 of the bottle to wax 2/3 of the car.
We need to 1/3 more to wax the entire car.
1/3 is half of 2/3.
We used 1/4 bottle for 2/3 of the car.
Therefore, we need half of 1/4 bottle for 1/3 more of the car.
1/4×1/2=1/8
We add this to the original 1/4 to see the total amount we used to wax the entire car.
1/4+1/8=3/8
Therefore, Rosy will use 3/8 of the bottle of car wax to wax her entire car.
