Answer:
45.39
Step-by-step explanation:
When the number in the thousandths place is 5 or above (until 9) you round up. If it is 0-4 you round down.
Answer:
a. the Student's t-distribution with 124 degrees of freedom
Step-by-step explanation:
We have no information about the standard deviation of the population, just for the sample, which means that the student's t-distribution is used.
Degrees of freedom
Sample size subtracted by 1.
125 households were sampled.
125 - 1 = 124 degrees of freedom.
So the correct answer is:
a. the Student's t-distribution with 124 degrees of freedom
Answer:
2916π in^2
Step-by-step explanation:
Step one:
given data
initial table diamter= 96in
we are told that the extension is 6 in over the edge
the new diameter is = 96+6+6= 108in
the radius is = 108/2=54in
we added 6 twice because it will be on the two sides of the diameter
Step two:
the expression for the area is
Area= πr^2
Area= π*54^2
Area= 2916π in^2
Answer:
p=0.25
Step-by-step explanation:
Given that a club can select one member to attend a conference. All of the club officers want to attend. There are a total of four officers, and their designated positions within the club are President (P), Vice dash President (Upper V )comma Secretary (Upper S )comma nbspand Treasurer (Upper T ).
Sample space would be
a){ {P}, {V}, {S} {T}} is the sample space with notations standing for as given in the question
b) Each sample is equally likely. Hence we have equal chances for selecting any one out of the four.
If probability of selecting a particular sample of size I is p, the by total probability axiom we have
\begin{gathered}4p =1\\p =0.25\end{gathered}
4p=1
