A used car dealer sells SUVs and cars. Of all the vehicles, 60% are cars. Of all the vehicles, 15% are red cars. What is the pro
kramer

Answer:

The probability that a car chosen at random is not red is 75%.

Step-by-step explanation:

Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:

60 = 100

15 = X

15 x 100/60 = X

25 = X

100 - 25 = 75

Therefore, the probability that a car chosen at random is not red is 75%.

Y=3/4x^2+9x vertex form?
Nutka1998 [239]

The standard form:

f(x)=ax^2+bx+c

The vertex form:

f(x)=a(x-h)^2+k\\\\h=\dfrac{-b}{2a};\ k=f(h)

We have

y=\dfrac{3}{4}x^2+9x\to f(x)=\dfrac{3}{4}x^2+9x\\\\a=\dfrac{3}{4},\ b=9,\ c=0\\\\h=\dfrac{-b}{2a}\to h=\dfrac{-9}{2\cdot\frac{3}{4}}=\dfrac{-9}{\frac{3}{2}}=-9\cdot\dfrac{2}{3}=-3\cdot2=-6\\\\k=f(h)\to k=f(6)=\dfrac{3}{4}(-6)^2+9(-6)=\dfrac{3}{4}(36)-54\\=(3)(9)-54=27-54=-27

Answer:

y=\dfrac{3}{4}(x-(-6))^2+(-27)=\dfrac{3}{4}(x+6)^2-27
