<h3>What is a Frequency?</h3>
Frequency is the number of times a data point or a set of points within an interval appears often in a data set.
The corresponding frequency to each of the interval given for the data would be as follows:
50 - 54: 2
55 - 59: 6
60 - 64: 7
65 - 69: 3
70 - 74: 2

Answer:
3
Step-by-step explanation:
Don't you mean 3z^3?
3z^3 - 300z = 0 can be factored: 3z(z^2-100) = 0
Then either z = 0, or z = 10 or z=-10.
Answer:
The sprinkler can spread water in a radius of 24 feet.
Step-by-step explanation:
Since the sprinkler sends water in a circular pattern in order to find the distance at which it can spread the water we need to find the radius of the circle. The area of the circle is said to be 1808.64 and it's formula is given by:
area = pi*r²
1808.64 = 3.14*r²
r² = 1808.64/3.14 = 576
r = sqrt(576) = 24 feet
The sprinkler can spread water in a radius of 24 feet.
