Answer:

Expected value E = $0.45

Step-by-step explanation:

Expected value E = P×w - P'×l

Where;

P = probability of making the next 2 throw.

P = 223/406 × 223/406 = 0.3017

P' = probability of not making a throw.

P' = 1 - P = 1 - 0.3017

P' = 0.6983

w = expected win = $20

l = Expected loss = $8

Substituting the values;

E = 0.3017 × $20 - 0.6983 × $8

E = $0.4476

Expected value E = $0.45

The equation below expresses the approximate

Answer:

The ball will be the 7 ft high at 2 different times.

Step-by-step explanation:

The height in meters of the ball is given by the following equation:

$h(t) = -16t^2 + 25t$

7 feet high

The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation

$2,1336 = -16t^2 + 25t$

$16t^2 - 25t + 2,1336 = 0$

At how many different times will the ball be 7 ft. High?

We have to find the number of solutions for the equation above.

It is given according to the value of $\Delta = b^2 - 4ac$ . If it is positive, there are two solutions, zero one solution and negative no solutions.

In this equation $a = 16, b = -25, c = 2.1336$ . So

$\Delta = b^2 - 4ac = (-25)^2 - 4*16*2.1336 = 488$

Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.
