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:
Step-by-step explanation:
The volume is Halfway
step 1
Find the radius of the circle
To find out the radius, calculate the distance between the center and any point that lie on the circle
so
(-2,3) and (-2,0)
Its a vertical distance
so
r=3-0=3 units
step 2
we have the radius r=3 units and the center (-2,3)
the equation of the circle is
Answer:
the first number in this sequence is 6....
Step-by-step explanation:
First number = x
2nd number = x+2
3rd consecutive even number = x+4
4th consecutive even number = x+6
Therefore,
By adding these numbers:
x+x+2+x+4+x+6= 36
Add the like terms:
4x+12=36
Combine the constants:
4x=36-12
4x=24
Divide both the terms by 4
4x/4 = 24/4
x= 6
Thus the first number in this sequence is 6....

Answer:
75 in^2
Step-by-step explanation:
The central vertical rectangle (including "ears") has dimensions
3 in wide by (9+2+2) = 13 in tall
Its area is
A = LW = (3 in)(13 in) = 39 in^2
__
The two rectangles either side of that have dimensions 2 in by 9 in. The area of each of them is
A = LW = (2 in)(9 in) = 18 in^2
__
The total net area is the sum of the areas of the parts:
left rectangle + central rectangle + right rectangle
= 18 in^2 + 39 in^2 + 18 in^2 = 75 in^2 . . . . surface area of the net
