Answer:</h2>
The correct statement that is used when a scatter plot is constructed is:
The independent variable is the input variable and should be represented by the x-axis.
<h2>
Step-by-step explanation:</h2>
We know that while plotting a graph or a scatter plot the x-axis which is the horizontal axis of the plot represents the input value or the value of the independent variable and the output value i.e. the value of the function corresponding to the input value is represented by the y-axis.
As the value of the output is evaluated corresponding to the input value hence the variable y is also known as the dependent variable and is represented by the y-axis.
Answer:
The rate of decrease is 8%
Step-by-step explanation:
we know that
The general equation for the radioactive decay can be written as:
where
a is the amount in kilograms after time t.
a_0 is the original amount of the substance or y-intercept of the function
r is the decay rate, written in decimals.
t is the time
In this problem we have
so
solve for r
Convert to percentage
5x/4 plug in any number by x
Answer:
Step-by-step explanation:
The volume of a sphere is
We are told our volume is 500pi/3, so we fill that in and solve for r:
Start by multiplying both sides by 3 over 4 pi:
Simplifying gives us
Take the cubed root of both sides to get that
r = 5
