Call a household prosperous if its income exceeds $100,000. Call the household educated if the householder completed college. Se

melisa1 [442]

Answer: 0.317

Step-by-step explanation:

Let A be the event that the selected household is prosperous and B the event that it is educated.

Given : P(A)=0.138, P(B)=0.261

P(A and B)=0.082

We know that for any events M and N ,

$\text{P(M or N)=P(M)+P(N)-P(M or N)}$

Thus , $\text{P(A or B)=P(A)+P(B)-P(A or B)}$

$\text{P(A or B)}=0.138+0.261-0.082\\\\\Rightarrow\text{ P(A or B)}=0.317$

Hence, the probability P(A or B) that the household selected is either prosperous or educated = 0.317

The scale on a map shows that 5 centimeters = 2 kilometers. What number of centimeters on the map represents an actual distance

liq [111]

Answer:

12.5 cm

Step-by-step explanation:

The ratio of map distance to ground distance is the same at any distance:

(map distance)/(ground distance) = (5 cm)/(2 km) = (x)/(5 km)

Multiply by 5 km and you have ...

x = (5 cm)(5/2) = 12.5 cm

The ground distance of 5 km is represented by 12.5 cm on the map.
