Step-by-step explanation:
We know that,

Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,

The percent of his sales that were less than or equal to 84 inches, is

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
<h2><u>
Answer:</u></h2>
y = cos ^- 1 (x)
Step-by-step explanation:
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
Answer:
The slope of line G is
.
Step-by-step explanation:
Given as :
The points of the line CH contains
C =
,
= - 2 , 6
H =
,
= 5 , -3
Let The slop of line CH = G
<u>Now, slope of line is </u>
G = 
i.e G = 
Or, G = 
Or,G = 
So, The slope of the line CH = G = 
Hence, The slope of line G is

hi
formula for cicrle circumference is 2 *radius*Pi
as radius is 45, Pi is 3.14....
I let you do the math...
Hope this answer helps, it would be 6 since there is 6 sides to a cube.
