An automotive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. Step 1 of 2: Su

AVprozaik [17]

Answer:

0.249 is the required proportion.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 822

Number of people who preferred foreign cars over domestic, x = 205

We have to find the proportion of new car buyers who prefer foreign cars.

Formula:

$\hat{p} = \dfrac{x}{n}$

Putting values, we get,

$\hat{p} = \dfrac{205}{822}\\\\\hat{p} = 0.249$

Thus, 0.249 is the proportion of the new car buyers who preferred foreign over domestic cars..

Two jets leave an air base at the same time and travel in opposite directions. One jet travels 80 mi/h faster than the other. If

Vesna [10]

Jet 1 moves with a speed of 672 mi/h, while jet 2 moves with a speed of 672 mi/h + 80mi = 752 mi/h.

Let's say that the rate (or speed) of the slower jet is R, then the rate of the faster jet is:

R + 80mi/h

Now, if we step on any of the two jets (such that we view it as if it doesn't move) the other jet will move with a speed equal to:

S = R + R + 80mi/h

We know that after 8 hours, the to jets are 11,392 mi apart, then we know that:

(R + R + 80mi/h)*8h = 11,392 mi

Now we can solve that for R:

2*R + 80mi/h = 11,392 mi/8h = 1,424 mi/h

R = 1,424 mi/h - 80mi/h)/2 = 672 mi/h

So Jet 1 moves with a speed of 672 mi/h, while jet 2 moves with a speed of 672 mi/h + 80mi = 752 mi/h.

Use euler’s formula to find the missing number faces :20 edges : 30 vertices ______

Mamont248 [21]

Answer:

8 Faces

Step-by-step explanation:

The Euler’s formula is:

V-E+F=2

Where V is number of vertices, E is number of edges and F is number of faces.

In our example, E=20, V=30, so we have:

30-20+F=2

10-F=2

F=8
