Answer:
In statistics, bivariate data is data on each of two variables, where each value of one of the variables is paired with a value of the other variable. ... For example, bivariate data on a scatter plot could be used to study the relationship between stride length and length of legs.

Answer:
B -1,5
Step-by-step explanation:
The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.
Volume of a sphere: 4/3r³
The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.
4/32.8³ = 91.95
The volume of the figure is 91.95 cm³.
The maximum height is 9.0 feet and the time to hit the ground is 4.5 seconds
<h3>How to determine the maximum height?</h3>
The function is given as:
f(x) = -0.6x^2 + 2.7x + 6
Differentiate
f'(x) = -1.2x + 2.7
Set to 0
-1.2x + 2.7 = 0
Subtract 2.7 from both sides
-1.2x = -2.7
Divide both sides by -1.2
x = 2.25
Substitute x = 2.25 in f(x) = -0.6x^2 + 2.7x + 6
f(2.25) = -0.6(2.25)^2 + 2.7(2.25) + 6
Evaluate
f(2.25) = 9.0
Hence, the maximum height is 9.0 feet
<h3>How to determine the time to hit the ground?</h3>
The time to hit the ground is twice the time to reach the maximum height.
In (a), we have:
x = 2.25
So, we have:
Time = 2 * 2.25
Evaluate
Time = 4.5
Hence, the time to hit the ground is 4.5 seconds
