Customers arrive at a movie theater at the advertised movie time only to find that they have to sit through several previews and prepreview ads before the movie starts. Many complain that the time devoted to previews is too long. A preliminary sample conducted by The Wall Street Journal showed that the standard deviation of the amount of time devoted to previews was five minutes. Use that as a planning value for the standard deviation in answering the following questions.a. If we want to estimate the population mean time for previews at movie theaters with a margin of error of 78 seconds, what sample size should be used
Answer:
57
Step-by-step explanation:
Given that :
Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds
Margin of Error, E = 78
Assume a confidence interval of 95%;
Using the relation :
((Zα/2 * σ) / E)²
(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025
Z0.025 = 1.96
Sample size = ((1.96 * 300) / 78)²
Sample size = (588 / 78)^2
Sample size = 7.5384615^2
Sample size = 56.828
= 57 samples

UW is the midsegment of ΔVXY,
By midsegment theorem of a triangle,
"Segment joining the midpoints of two sides of a triangle is parallel to the third side and measure of midsegment is half of the length of the third side."
UW = [tex]\frac{1}{2}(XY)[/tex]
Since, XY = 30 units
UW = [tex]\frac{1}{2}(30)[/tex]
= 15 units
Therefore, length of the midsegment UW = 15 units will be the answer.

Which method shows the two triangles are congruent?
A . SSS
B . SAS
C . ASA
D . AAA
Answer:
SAS
Step-by-step explanation:
It's the only answer that can satisfy with the figures
By B. SAS (side, angle, side) congruency theorem shows the two triangles are congruent
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
The congruency theorem should always be consecutive angles or sides to the corresponding consecutive angles or sides.
Side PR and VS are congruent also m∠R and m∠V is similar and the sides VT and QR is also congruent.
Therefore, The congruency theorem that holds this is SAS.

Solve using Y=Mx+b
M=-5 and (-3,-2)
Given:
M=-5 and (-3,-2).
To find:
The equation in the form [tex]y=mx+b[/tex].
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
We have m=-5. Putting m=-5 in (i), we get
[tex]y=-5x+b[/tex] ...(ii)
We have a point (-3,-2). Putting x=-3 and y=-2 in (ii), we get
[tex]-2=-5(-3)+b[/tex]
[tex]-2=15+b[/tex]
[tex]-2-15=b[/tex]
[tex]-17=b[/tex]
So, the value of b is -17.
Putting b=-17 in (ii), we get
[tex]y=-5x+(-17)[/tex]
[tex]y=-5x-17[/tex]
Therefore, the required equation is [tex]y=-5x-17[/tex].

Given:
The graph of a function [tex]y=h(x)[/tex].
To find:
The interval where [tex]h(x)>0[/tex].
Solution:
From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, [tex]h(x)>0[/tex] for [tex]x<0[/tex] and [tex]x>3.6[/tex].
The function between x=0 and x=3.6 lies below the x-axis. So, [tex]h(x)<0[/tex] for [tex]0<x<3.6[/tex].
Now,
For [tex]-1<x<0[/tex], the graph of h(x) is above the x-axis. So, [tex]h(x)>0[/tex].
For [tex]0<x<1[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].
For [tex]1<x<2[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].
Only for the interval [tex]-1<x<0[/tex], we get [tex]h(x)>0[/tex].
Therefore, the correct option is A.
