The value of cumulative frequency is the sum of all previous frequencies. We should have 26 at the end of the table because all frequency add up to 26
To graph the cumulative frequency, we would need the plots.
Use the end of value range against the cumulative frequency valueRange 40-49, use the value 49 against the cumulative frequency 1
(49, 1)(59, 3)(69, 5)(79, 12)(89, 21)(99, 26)
Plot these on graph and connect them as a curve.
Hi there!
From the unit circle, we can locate the two values of sine Ф (y-value of the coordinate) at which sin Ф = √3/2.
The two values are Ф = π/3 and 2π/3.
The required inequality statement tonmode’ the scenario given is : 16 + 6s ≥ 40
- The number fencing leftover = 8 foot × 2 = 16 feet
- Required number of fencing ≥ 40
- The additional number of 6 foot fencing required = s
Representing this as an inequality :
- Left over + additional fencing ≥ 40
Therefore,
