Step-by-step explanation:
Answer:
The z-value rounded to the nearest hundredth is -1.64
There is no enough evidence to reject the claim.
Step-by-step explanation:
A certain website claims that it averages 4.7 hours of downtime per month.
No. of samples = n = 17
Mean =
Standard deviation =
Formula:
Z =−1.64
Z critical at 90% is 1.65
Since Z calculated < Z critical
So, there is no enough evidence to reject the claim.
Answer:
The graph belongs to the conic family called circle. Assign several values for
θ
then compute corresponding
r
then plot the graph
Explanation:
The given
r
=
4
sin
θ
is equivalent to
x

and by completing the square

also using the "center-radius form#

now, you are ready to graph
kindly see the graph below
graph{x^2+y^2=4y[-10,10,-5,5]}
You may also use
r
=

sin
θ
right away by assigning values for
θ
and noting all

)
coordinates.
Step-by-step explanation:
Answer: Maximum- 327,000
Minimum- 273,000
Step-by-step explanation:
Since the variation is by 27,000, maximum expected production will be:
300,000+27000
While minimum expected production will be 300,000-27000
Answer:
the answer is B.
Step-by-step explanation:
The mathematical domain includes all real numbers, while the reasonable domain includes only rational values greater than or equal to 0.
