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
The tiger could polish off everything on that list in no time.
It would take him zero days to eat all of it, because all the prey
that you have listed adds up to zero pounds of meat.

Step-by-step explanation:
Answer: x = 3
Step-by-step explanation
This is a simultaneous equation. So to find x , we solve to ascertained the coordinate or point of intersection of the too lines.
y = 4x + 2, and 6x - y = 4
To solve , we need to rearrange first
y = 4x + 2 will be
4x - y = -2 -------------------------1
Equation 2 is in order
6x - y = 4 -------------------------- 2
Now solve the two equation for x by using any methods you are familiar with.
4x - y = -2
6x - y = 4, now subtract equation 2 from 1 in order to eliminate y,
we now have
-2x = -6, now divide through by 2
x = 3.
Hence y could be find by substitution for x in any of the equation above and now check.
4x - y = -2
4(3) - y = -2
12 - y = = -2
y = 12 + 2
y = 14.
Now let check
6x - y = 4
6(3) - 14
18 - 14
= 4.
Therefore, the value of x is 3
