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:
If you need the equation: 10x - 12
If you need the equation more simplified: x - 1.2
Step-by-step explanation:
(2x + 7) - (8x + 5)
Move the parts of the equation around
(2x + 8x) - (7 + 5)
Add 2x and 8x together
10x - (7 + 5)
Add 7 and 5 together
10x - 12
If you need it even more simplified, continue
10x - 12
Divide by 10
x - 12/10
Simplify
x - 1.2
I Hope That This Helps! :)
18/100 or 9/50
24/100 or 6/25
82/100 or 41/50
61/100
95/100 or 18/50
28/100 or 7/25
Answer:
X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
Answer:
9,962
Step-by-step explanation:
3,489+8,617+1,240=13,346
564*6=3,384
13,346-3,384=9,962
