You want to invest in companies belonging to Gispa Group of 1
Companies, Inc. so you did some research and found out that companies belonging to this group has an average gain of
0.8
percent and standard deviation of
0.7
percent. Given that a positive percent (gain) means profit and a negative percent means a loss. If you choose
20
companies, what is the probability that the companies are gaining more than
1
percent?

1.2803

Step-by-step explanation:

According to the Question,

Therefore, We have Average Gain(ц) = 0.8%

Standard deviation(σ) = 0.7%

Number of Companies(n) = 20

= (σ² × n) / ц  ⇒  (0.7²×20) / (0.8*10) = 1.2803

the two may have that, even a breakdown is probably offered

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
