SpyIntel [72]

Answer:

The probability that a customer purchases a black SUV is 0.05.

Step-by-step explanation:

<em>The question is incomplete:</em>

<em>At a certain car dealership, the probability that a customer purchases an SUV is </em><em>0.20</em><em>. Given that a customer purchases an SUV, the probability that it is black is </em><em>0.25</em><em>.</em>

The probability that a customer purchases a black SUV can be calculated as the multiplication of this 2 factors:

The probability of a customer purchasing a SUV: P(SUV).
The probability that it is black, given that he or she purchases a SUV (conditional probabilty): P(B|SUV)

We know then:

$P(SUV)=0.25\\\\P(B | SUV)=0.20$

We can now calculate the probability as:

$P(B\,\&\,SUV)=P(B|SUV)\cdot P(SUV)=0.25\cdot0.20=0.05$

A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is th

maria [59]

The question is modelled as shown in the diagram below

We have the angle, 30° and we know the length of the side opposite the angles, 25000 feet. We are looking for the ground distance between the plane and the tower. We will use the trigonometry ratio of Tan

$tan(x)= \frac{opposite}{adjacent}$
$tan(30)= \frac{25000}{y}$
$y= \frac{25000}{tan(30)}$
$y=43301.27019$

The distance between the point directly beneath the plane and the tower is 43301.3 feet (rounded to 2dp)

Calculate the amount of drug in milligrams for the following dispensed containers;

qwelly [4]

We know, 1 oz = 28349.5 mg
so, 7 oz = 198447

So, it would be: 198447 * 2%
= 198447 * 0.02
= 3968.24 mg

In short, Your Answer would be 3968.24 mg

Hope this helps!

zhenek [66]

Answer:

C = 110 cm

Step-by-step explanation:

The circumference is given by

C = pi *d

C = 3.14 * d

C = 3.14 * 35

C =109.9

Rounding

C = 110 cm
