A-k = w + v
a-k = w + v
+k +k
the k’s on the left side cancel out
a = w + v + k
Answer:
1.2803
Step-by-step explanation:
According to the Question,
- Given That, 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 have an average gain of 0.8 percent and a standard deviation of 0.7 percent.
- And, a positive percent (gain) means profit and a negative percent means a loss. If you choose 20 companies.
Therefore, We have Average Gain(ц) = 0.8%
Standard deviation(σ) = 0.7%
Number of Companies(n) = 20
- So, the probability that the companies are gaining more than 1 percent is
= (σ² × n) / ц ⇒ (0.7²×20) / (0.8*10) = 1.2803
Answer: n=66
Step-by-step explanation:
2n -2 = n + 64 subtract 1n on both sides
- n - n The n’s cancel out
————————
1n - 2 = 64 Add 2 on both sides
+2 +2 The 2’s cancel out
——————-
1n = 66 Divide 1 on both sides
—- ——
1 1 The 1’s cancel out
n= 66
Check it :
2(66) - 2 = 66 + 64
132 - 2 = 130
130 = 130
