Answer:
8ft.
Step-by-step explanation: If you are finding he area, 2 times 4 equals 8, so the answer would be 8 feet.
Answer:
100*25
Step-by-step explanation:
sum of 25=25
Answer:
--- Variance
Step-by-step explanation:
Given
Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.
For 59 - 66
For 67 - 74
For 75 - 82
For 83 - 90
So, the table becomes:
The mean is then calculated as:
-- approximated
Solving (b): The sample variance:
This is calculated as:
So, we have:
-- approximated
How do linear, quadratic, and exponential functions compare?
Answer:
How can all the solutions to an equation in two variables be represented?
<u><em>The solution to a system of linear equations in two variables is any ordered pair x,y which satisfies each equation independently. U can Graph, solutions are points at which the lines intersect.</em></u>

<u><em>How are solutions to a system of nonlinear equations found?
</em></u>
Solve the linear equation for one variable.
Substitute the value of the variable into the nonlinear equation.
Solve the nonlinear equation for the variable.
Substitute the solution(s) into either equation to solve for the other variable.

<u><em>How can solutions to a system of nonlinear equations be approximated? U can find the solutions to a system of nonlinear equations by finding the points of intersection. The points of intersection give us an x value and a y value. Using the example system of nonlinear equations, let's look at how u can find approximate solutions.</em></u>
