Answer:
A) x= - u/6
Step-by-step explanation:
u= - 6x
-6x= u
x= - u/6
Answer:
domain: ( -∞,∞) , {x | x ∈ R}
range:( -∞,∞) , {y | y ∈ R}
Step-by-step explanation:
you got to find the domain by finding where the equation is defined. the range is set of values that correspond with the domain.
Answer:
To write this down as an algebraic expression you would simply need to multiply the two terms together.
So in this case it would be 8 multiples by x which is 8x
Step-by-step explanation:
1) Find out the variables in the Expression
2) Find the operation that is done to the variables
3) Apply the operation to those variables.
Answer: 482
Step-by-step explanation:
Formula to find the sample size is given by :-
(1)
, where z* = critical z-value (two tailed).
= Population standard deviation and E = Margin of error.
As per given , we have
Margin of error : E= 3
Confidence level = 90%
Significance level =
Using z-table , the critical value for 90% confidence=
Required minimum sample size = [Substitute the values in formula (1)]
[ Round to the next integer]
Hence, the number of observations required is closest to 482.
Answer:
x = 118.572091090591
Step-by-step explanation:
we are given a right triangle then
tan(16) = 34/x
then
x = 34÷tan(16)
=118.572091090591
Info :
tan(16) = 0.286745385759
