Answer:
The length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet.
Step-by-step explanation:
The total area, in square feet, of a rectangular stage that has been widened by x feet, is represented by 1,900 + 76x.
Now, factorizing the expression for the area we get,
A = 1900 + 76x
⇒ A = 76(25 + x)
Therefore, from the above expression, we can assume that the length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet. (Answer)
Apparently the questionnaire is incomplete, then the first part necessary to solve the question is left
The average daily volume of a computer stock in 2011 was
muμequals=35.135.1
million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of
3030
trading days in 2014, he finds the sample mean to be
30.330.3
million shares, with a standard deviation of
sequals=12.612.6
million shares. Test the hypotheses by constructing a
9595%
confidence interval. Complete parts (a) through (c) below.
Answer: however, with the given options we can say that the correct option is "B", in which the value of the confidence interval is necessary to accept or reject the null hypothesis, we deduce that the value is not in the confidence interval so it must be rejected
Answer:
yea sure
Step-by-step explanation:
why not
Part A.
The venn diagram is attached. In the venn diagram, circle A represent the number of responds that have an ASU parking deal. Circle B represent the number of respondents that ride their bike to campus and circle C represent the number of respondents that that ride the Light Rail.
Part B.
From the venn diagram, the number of respondents that ride the Light Rail and ride their bike to campus is given by 39 –
12 = 27
Part C.
From the venn diagram, the number of respondents that only have an ASU parking decal is given by <span>77 –
12 – 8 – 6 = 51
Part D.
The number of respondents that ride the Light Rail or have an ASU decal is given by the sum of the number of respondents that ride the Light Rail only and those that have an ASU parking decal and those that have both ASU parking decal and ride their bike to school.
This is given by 51 + 8 + 28 = 87.
Part E.
The venn diagram showing the area </span><span>that represents people who have a parking decal or who ride their bike to campus but who do not ride the Light Rail</span> sgaded is attached.
I/3 of 123 is 41
41 dollars are taken off, so 123-41=82
the sale price is 82 dollars
