Answer:

A.

Step-by-step explanation:

We can eliminate answer choices by looking at several factors. If the parabola opens upward, there cannot be a negative number as 'a'. Recall that standard form of a parabola is y= ax² + bx + c.

Therefore, any choice that has a negative number as 'a' opens downward. This leaves answers A and C.

Next, for the parabola to appear narrower, it must have some kind of vertical stretch or horizontal compression. 'A' is the only choice that has a vertical stretch transformation done to the parabola. The correct answer is A.

Answer:

A

Step-by-step explanation:

A parabola opening up will have a positive value for the a value in ax^2+bx+c form. Also, the larger the absolute value of the a value, the more narrow the parabola will appear.

Hope this helps!

Math algebra HELP!!!!
erastovalidia [21]

Answer:

y = 32

Step-by-step explanation:

\frac{1}{2} y + 22 = 38

Subtract 22 from both sides to isolate the y variable.

\frac{1}{2} y = 16

Divide both sides by \frac{1}{2}, which is the same as multiplying by 2.

y = 32

Customers who purchase an aluminum-structured Audi A8 can order an engine in any of three sizes: 2.0L, 2.4L, and 2.8L. Of all Au
sergiy2304 [10]

Answer:

The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.

Step-by-step explanation:

Let's denote event as follows:

<em>A</em> = an Audi A8 car has a 2.0L engine.

<em>B</em> = an Audi A8 car has a 2.4L engine.

<em>C</em> = an Audi A8 car has a 2.8L engine.

<em>X</em> = an Audi A8 car failed emissions test taken within four years of purchase.

The information provided is:

P(A)=0.45\\P(B)=0.35\\P(C)=0.20\\P(X|A)=0.10\\P(X|B)=0.12\\P(X|C)=0.15

The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is:

P(B|X)=\frac{P(X|B)P(B)}{P(X)}

Compute the probability of an Audi A*8 car failed emissions test taken within four years of purchase as follows:

P(X)=P(X|A)P(A)+P(X|B)P(B)+P(X|C)P(C)\\=(0.45\times0.10)+(0.35\times0.12)+(0.20\times0.15)\\=0.117

Compute the value of P (B|X) as follows:

P(B|X)=\frac{P(X|B)P(B)}{P(X)}=\frac{0.35\times0.12}{0.117} =0.3589

Thus, the probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.
