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

An aerosol can contains gases under a pressure
slavikrds [6]

Answer:

temperature on the beach = T2 = 34.56 °C

Step-by-step explanation:

We are given;

P1 = 4.5 atm

T1 = 24 °C = 24 + 273 = 297 K

P2 = 4.66 atm

Thus, P1/T1 = P2 /T2

So, T2 = P2•T1/P1

Thus, T2 = (4.66x 297)/4.5

T2 = 307.56 K

Let's convert to °C to obtain ;

T2 = 307.56 - 273

T2 = 34.56 °C
