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.

The graph shows the first 45 minutes of Darlene's bike trip. If she continues at a constant rate, how far will she travel in two
julia-pushkina [17]

the slope or average rate of change for the trip from the graph is just rise/run.  Now, let's take a look at those values to get it

\bf slope\implies \cfrac{rise}{run}\implies \cfrac{distance}{time(mins)}\implies \cfrac{9}{45}=\cfrac{8}{40}=\cfrac{7}{35}=\cfrac{6}{30}=\cfrac{5}{25}\implies \stackrel{\stackrel{slope}{\downarrow }}{\cfrac{1}{5}}

so the slope of it is 1/5, 2 hours is 120 minutes, what would be the distance value on 120 minutes?

\bf \cfrac{distance}{time(mins)}=\stackrel{slope}{\cfrac{1}{5}}\qquad \qquad \cfrac{\stackrel{miles}{d}}{\underset{minutes}{120}}=\cfrac{1}{5}\implies d=\cfrac{120}{5}\implies d=24

Determine whether or not the given procedure results in a binomial distribution. If not, identify which condition is not met. Sp
Ostrovityanka [42]

Answer:

The procedure does results in a binomial distribution.

Step-by-step explanation:

For a binomial probability distribution to be applicable, certain conditions have to be met which are :

There must be a fixed number of observations ; here the number of observations are : 79

All observations must be independent ; the observations are independent ; odd or even

Observations must fall into one of two categories : success category or failure. Here, observations can be odd or even

The probability of success must be equally likely for each observation.

Hence, the procedure results in a binomial probability distribution.

WXYZ is a parallelogram. Find the measure of angle Z
Delvig [45]

Given:

The figure of a parallelogram.

To find:

The measure of angle Z.

Solution:

We know that, the consecutive interior angles of a parallelogram are supplementary angles, it means there sum is 180 degrees.

In the given figure angle W and angle Z are supplementary angle. So,

m\angle W+m\angle Z=180^\circ

(18b-11)^\circ+(9b+2)^\circ=180^\circ

(27b-9)^\circ=180^\circ

(27b-9)=180

Adding 9 on both sides, we get

27b=180+9

27b=189

b=\dfrac{189}{27}

b=7

Now,

m\angle Z=(9b+2)^\circ

m\angle Z=(9(7)+2)^\circ

m\angle Z=(63+2)^\circ

m\angle Z=65^\circ

Therefore, the correct option is C.
