The graph of a quadratic equation, or a parabola, looks like a U, an upside down U, a C, or a backwards C. We can use the following rules to determine what the graph of a given quadratic equation looks like. If y = ax2 + bx + c, and a is positive, then the graph of the equation is the shape of a U.

A spinner is divided into four equal sections labeled 1, 2, 3, and 4. Another spinner is divided into three equal sections label

Romashka-Z-Leto [24]

Since we are asked to compute the probability of two event with "or"
statement, then we will add the probabilities like this:
Denote A the first event and B the second event:
$P(A\cup B)=P(A)+P(B)$
A="Get an even number":
$P(A)= \frac{2}{4}= \frac{1}{2}$
B="Get section B":
$P(B)= \frac{1}{3}$
Conclusion:
$P(A\cup B)=P(A)+P(B)= \frac{1}{2} +\frac{1}{3}\\=\frac{5}{6}$
The probability is 5/6

Mr. and Mrs. Lorenzo have saved $38,430 for the home they want to buy

Information about the problem:

Initial cost = $213,500

Final savings =?

To solve this exercise we have to apply the percentage formula:

Final savings = initial cost * savings / 100

Final savings = $213,500 * 18 / 100

Final savings = $213,500 * 0.18

Final savings = $38,430
