Step-by-step explanation:

From given data,

n = 1496

x = 478

Proportion estimate ( p ) = \frac{x}{n}

                                        = \frac{478 }{1496} = 0.3195 ≅ 0.31

Proportion estimate ( p ) = 0.31

∴ The proportion of new car buyers who prefer foreign cars -> 0.31

Y=52(0.42)^x identify if it's growth or decay and determine the percentage rate of increase or decrease
Shkiper50 [21]

Answer:

58%

Step-by-step explanation:

Given the exponential relation :

Y=52(0.42)^x

Since 0.42 is less than 1, then we can infer that the expression is a Decay function ;

. General form of a exponential function :

y = A(1 - r)^x ; r = Decay rate

Comparing the general equation with the equation given ;

The percentage rate of decrease is obtained thus :

1 - r = 0.42

1 - 0.42 = r

r = 0.58

Rate = 0.58 * 100%

Rate = 58%
