then rounded its 0.68
Step-by-step explanation:
Find the number in the hundredth place
8
and look one place to the right for the rounding digit

. Round up if this number is greater than or equal to
5
and round down if it is less than
5
.

A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2) [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).
So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).
the volume of cube with edge length 11 m is 
.
<u>Step-by-step explanation:</u>
Here we have a side length of a cube as 11 m . We need to find the volume of cube . Let's find out:
We know that every side of a cube is identical and equal . And volume of cube is given by formula :
⇒ 
...........(1)
According to question we have following parameters as
Putting this in (1)
⇒ 
⇒ 
⇒ 
⇒
Therefore , the volume of cube with edge length 11 m is .
The annual salaries at a particular company are approximately normally distributed with a mean is 0.42124
Manufacturing job :
Mean (m) = 40,000
Standard deviation (s) = 9000
Sales job :
Mean (m) = 35000
Standard deviation (s) = 9000
Probability of earning more than 45000 if one or the other job is selected;
Obtaining the standardized scores and probability for each :
Z = (x - m) / s
P(x > 45000)
Z = (45000 - 40000) / 9000 = 0.5555
= 0.56
P(Z > 0.56) = 0.28774(Z probability calculator)
For sales
P(x > 45000)
Z = (45000 - 35000) / 9000 = 1.1111111
= 1.11
P(Z > 1.11) = 0.1335 (Z probability calculator)
0.28774 + 0.1335 = 0.42124
