Suppose a NBA basketball player has 5% chance of picking up a foul every minute he plays. What is the probability that he will p
alukav5142 [94]

Answer:

He wont foul out with probability 0.9093

Step-by-step explanation:

The total number of fools he picked is a Binomial ditribution noted by X with parameters p = 0.05 and N = 48. The mean of this random variable is μ = np = 48*0.05 = 2.4 and the variance is σ² = np(1-p) = 2.4*0.95 = 2.28, hence its standard deviation is σ = √2.28 = 1.51.

Note that, if approximate probability is asked, we could just approximate X with a Normal random variable with mean 2.4 and standard deviation 1.51 (this can be done because of the central limit theorem). We will calculate the probability manually. He wont foul out if he picks 0,1,2,3 or 4 fouls, thus

P(X \leq 4) = P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4) \\= 0.95^{48}+48*0.95^{47}*0.05+{48 \choose 2}*0.95^{46}*0.05^2+\\{48 \choose 3}*0.95^{45}*0.05^3+{48 \choose 4}*0.95^{44}*0.05^4 \\= 0.085+0.215+0.266+0.215+0.127 = 0.9093

As a consecuence, he wont foul out with probability 0.9093.

Find the equation of the line passing through the points (2 11) and (-8 -19)
Svet_ta [14]

Answer:

Y=2x+7

Step-by-step explanation:

To find the gradient of the line u have to subtract the y intercepts and the x intercepts

11--9/2--8=20/10=2

Y-11/x-2=2

Y-11=2(x-2)

Y-11=2x-4

Y=2x-4+11

Y=2x+7

Find the derivative of <br> y = 1/ (3x^3) with steps
Ganezh [65]

Answer:

- 9 {x}^{ - 4}

Step-by-step explanation:

y =  \frac{1}{ {3x}^{3} }  =  {3x}^{ - 3}

y =  <  - 3 \times 3 >  {x}^{ - 3 - 1}  \\  =  - 9 {x}^{ - 4}

Assoli18 [71]

Answer:

42.7 m

Step-by-step explanation:

The Circumference of a circle is found by multiplying the radius of the circle by 2π.  Here the radius is 6.8 m.  The circumference of this circle is

C = 2π(6.8 m) = 13.6π m, or (to 1 decimal place, 42.7 m.
