I don't see a chart, but, to find the mean you add all of the values up together and then divide by however many values you added.
For example, if she bakes 5 cakes one month, 7 cakes another month, and 2 cakes a final month, you'd add 5 + 7 + 2 to get 14. Then you'd divide 14 by 3, since you added 3 values together.
If you still need help, post the chart and I'll explain further.
Answer:
Factoring is a step taken towards solving a quadratic equation. ... You cannot factor them, the only way to find the roots then, is by using the quadratic formula. Suppose you factor the quadratic polynomial as and . Then set them equal to zero and solve for , you will have
Step-by-step explanation.
Example 1 – Solve: x2 + 16 = 10x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
1.78 is the correct answer.
