Answer:
Step-by-step explanation:
(7 - 11)/(0 + 5) = -4/5
Answer:
Total of the frequency = The last values of the cumulative frequency (c.f) = 100
Step-by-step explanation:
From the frequency distribution table given in the question, the cumulative frequency (c.f) can be computed by adding each frequency to the sum or total of the preceding frequencies. This makes the last value of the cumulative frequency (c.f) to be equal to the total of the frequency.
Based on this explanation, we have:
<u>mass </u><em><u>m</u></em><u> (kg) </u> <u> frequency </u> <u> mass </u><em><u>m</u></em><u> (kg) </u> <u> c.f </u>
0 < <em>m</em> ≤ 0.1 2 <em> m</em> ≤ 0.1 2
0.1 <<em> m</em> ≤ 0.2 7 <em>m</em> ≤ 0.2 9
0.2 < <em>m</em> ≤ 0.5 32 <em>m</em> ≤ 0.5 41
0.5 < <em>m</em> ≤ 0.8 46 <em>m</em> ≤ 0.8 87
0.8 <<em> m</em> ≤ 1 13 <em>m</em> ≤ 1 100
From the above, we can observe that:
Total of the frequency = 2 + 7 + 32 + 46 + 13 = 100
The last values of the cumulative frequency (c.f) = 100
Therefore, we have:
Total of the frequency = The last values of the cumulative frequency (c.f) = 100
Answer:
The height of the car at the end of the ride is 4 m above the ground level
Step-by-step explanation:
Let
h ------> the height of the car
1) The car starts at 1 meter above ground level
so
the height of the car in this moment is equal to
h=+1 m----> is positive because is above ground level
2) The car drops 4 meters
the height of the car in this moment is equal to
h=1-4=-3 m -----> is negative because is below ground level
3) The car rises 13 meters
the height of the car in this moment is equal to
h=-3+13=10 m ----> is positive because is above ground level
4) The car drops 6 meters
the height of the car in this moment is equal to
h=10-6=4 m -----> is positive because is above ground level
therefore
The height of the car at the end of the ride is 4 m above the ground level
First you multiply 5*5 which is 25 and then you multiply 25*12 which is 300 and 300*14 is 4,200.so your answer is 4,200
