The minimum value shown on the line plot is 18.0. The maximum value depicted on the line plot is 22.0. The most frequently occurring height in inches is 19.5, appearing 3 times. A line plot is a visual representation that illustrates the frequency (how often data values occur) across a number line. Dots are marked on the line plot for each value along the number line.
This slope can be described as passing through the origin or more formally, the point (0,0).
Response:

Detailed explanation:
Probability for an event is calculated as the ratio of the size of the event space compared to that of the sample space.
The sample space encompasses all possible outcomes.
Event space represents the number of favorable outcomes for the event in question.
Thus
Let
x ------> size of event space
y ----- → size of sample space
so

Subtracting seven from sixteen results in nine
The solution is nine
To determine the values of b that fulfill 3(2b+3)^2 = 36
we start with
3(2b+3)^2 = 36
Divide both sides by 3
(2b+3)^2 = 12
Next, take the square root of both sides
(2b+3)} = (+ /-) \sqrt{12} \\ 2b=(+ /-) \sqrt{12}-3
b1=\frac{\sqrt{12}}{2} -\frac{3}{2}
b1=\sqrt{3} -\frac{3}{2}
b2=\frac{-\sqrt{12}}{2} -\frac{3}{2}
b2=-\sqrt{3} -\frac{3}{2}
Thus,
the solutions for b are
b1=\sqrt{3} -\frac{3}{2}
b2=-\sqrt{3} -\frac{3}{2}
