Give the values a, b, and c needed to write the equations standard form. 2/3(x-4)(x+5)=1

Verizon [17]

The standard form of the quadratic equation is given by:
ax ^ 2 + bx + c
What we must do in this case is to rewrite the given equation.
We have then:
2/3 (x-4) (x + 5) = 1
(x-4) (x + 5) = 3/2
(x ^ 2 + 5x-4x-20) = 3/2
2x ^ 2 + 2x-40 = 3
2x ^ 2 + 2x-43 = 0
Thus, the values of a, b and c are:
a = 2
b = 2
c = -43
Answer:
a = 2
b = 2
c = -43

zysi [14]

Answer:

Step-by-step explanation:

cheese With toppings Total

No of pizzas sold 24 16 40

Eaten at work 12 10 22

Not eaten at work 12 6 18

a) Prob for a cheese pizza eaten at work= $\frac{12}{40} =0.30$

b) Prob a pizza with either one or more toppings, and it was not eaten at work.= $\frac{6}{40} =0.15$

c) Prob for a cheese pizza, or it was a pizza eaten at work.=P(cheese)+P(pizza eaten at work)-P(both)

= $\frac{24}{40} +\frac{22}{40} -\frac{12}{40} \\=\frac{34}{40} \\=0.85$
