Check my steps and for part b, the professor wants us to show are work and I don't know how to solve it by hand.
Ugo [173]
Part a is correct.

Part b can be done a couple ways.
1) Use binomial distribution. p = 0.2, n = 144
P(x>3) = 1 - P(x=0) -p(x=1) -p(x=2) -p(x=3)
where
P(x=k) = (nCk)p^k (1-p)^{n-k}

2) Assume a normal distribution with mean = 28.2, stdev = 4.8
z = \frac{4 - 28.2}{4.8} = -5.04
Look up z-value in normal table to find probability.

Hope that helps.

Please help, legit need to study for so many exams and this is the last thing on my mind to do. Appreciate anybody willing to he
Ivenika [448]

Answer:

x=13

z=84

Step-by-step explanation:

The intersection of two of these lines actually have relationships. The two angles that have the variable x both add up to 180 degrees since we assume for them to be a straight line, and the angle with '11x-59' is equal to Z since they are vertical from each other.

Knowing this, we can add the two equations together and equal it to 180. This is to give us the variable x.

(11x-59)+(13x-73)=180       (always use parenthesis!)

24x-132=180                     (combine like terms)

24x=312

x=13                                   (isolate x)

We now know that the x stands for 13, but we are not done. By plugging in the variable x in for the equation 11x-59, we can find the value of z since they are vertical angles.

11(13)-59=84

z=84
