Answer:
Hey!
V = 1906.624 cm^3
SA= 922.56 cm^2
Step-by-step explanation:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.
Volume of a cube = side times side times side.
Answer:
4/63
Step-by-step explanation:
Multiple: 2/
5
* 2/
7
= 2 · 2/
5 · 7
= 4/
35
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(4, 35) = 1. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - two fifths multiplied by two sevenths = four thirty-fifths.
Multiple: the result of step No. 1 * 5/
9
= 4/
35
* 5/
9
= 4 · 5/
35 · 9
= 20/
315
= 4 · 5/
63 · 5
= 4/
63
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(20, 315) = 5. In the following intermediate step, cancel by a common factor of 5 gives 4/
63
.
In other words - four thirty-fifths multiplied by five ninths = four sixty-thirds.
Answer:
$4.911 million or $6.481 million
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Step-by-step explanation:
Given that:
sample size n = 18
standard deviation σ = 1.70
confidence interval = 95%
Sample mean
5.696
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The critical value of from the Z tables
The 95% C.I for the mean is;
= 5.696 ± 0.785372
= (5.696 - 0.785372 , 5.696 + 0.785372 )
= ( 4.910628 , 6.481372 )
≅ $4.911 million or $6.481 million.
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
