The ball initially goes up then reaches a maximum height from which it

returns downwards and stops in the basket.

Please find attached the graph that represents the relationship between the height of the ball and time.

Reasons:

  • The initial height of the basketball = 5 feet

  • The motion of the basketball is a parabola, which is concave downwards.

  • Given that the basket ball becomes stuck in the net and that the net is higher than 5 feet, we have that the position of the ball after it comes to rest will be higher than the initial position.

Therefore;

The graph of the motion of the ball representing the relationship between he height of the ball and time is as presented in the attached graph crated with MS Excel.

Six percent of computer chips produced by Cheapo Chips are defective. Each month a random sample of 200 chips manufactured that
zzz [600]

Using the binomial distribution, it is found that the mean of X is of 12, with a standard deviation of 3.36.

For each chip, there are only two possible outcomes, either it is defective, or it is not. The probability of a chip being defective is independent of any other chip, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of exactly <u>x successes on n repeated trials, with p probability.</u>  

The mean of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

In this problem:

  • Six percent of computer chips produced by Cheapo Chips are defective, hence p = 0.06.
  • Each month a random sample of 200 chips manufactured that month are taken, hence n = 200

Then:

E(X) = np = 200(0.06) = 12

\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{200(0.06)(0.94)} = 3.36

The mean of X is of 12, with a standard deviation of 3.36.

Find the length of the line segment shown below.
Marina86 [1]

Answer:

The end points of line segment are:

(x_1,y_1) = (5,4)\\(x_2,y_2)  = (-4,-3)

Using distance formula,

Distance = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}} = \sqrt{(-4-5)^{2}+(-3-4)^{2}} = \sqrt{(-9)^{2}+(-7)^{2}} = \sqrt{81+49}=\sqrt{130} units
