(1) y=x-2  
(2) y=x²-2

Then we deduce that x-2 = x²-2 ===> x²-x = 0 ==x(x-1) =0

so x = 0 or x =1. Plug these values in any of the equation to find y & you will find:

 for x = 0, y = -2  & for x= -1 , y= -1

(c) what is the probability that at least one adult prefers milk chocolate to dark chocolate?
Schach [20]
Part A:

Given that 47% of adults prefer milk chocolate to dark chocolate, for a random sample of n = 4 adults, the probability that all four adults say that they prefer milk chocolate to dark chocolate is given by

P(4)=(0.47)^4=0.049



Part B:

The probability that exactly two of the four adults say they prefer milk chocolate to dark chocolate is given by

P(2)={ ^4C_2(0.47)^2(1-0.47)^2} \\  \\ =6(0.2209)(0.2809)=0.372



Part C:

The probability that at least one adult prefers milk chocolate to dark chocolate is given by

P(at \ least \ 1)=P(X\geq1) \\  \\ =P(1)+P(2)+P(3)+P(4) \\  \\ =1-P(0)=1-{ ^4C_0(0.47)^0(1-0.47)^4} \\  \\ =1-(0.53)^4=1-0.0789=0.921

Find the slope of the following graph<br><br> a) 1/2<br> b) 2 <br> c) -2<br> d) -1/2
FinnZ [79.3K]

Answer:

c. -2

Step-by-step explanation:

because the linear line goes down we know it is negative

and its not 1/2 because it is rise over run. it runs 1 and rises 2 (or drops 2 because it is negative)

rise over run = -2/1 = -2
