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:

See the explanation below.

Step-by-step explanation:

f(t)=21020\left(1+0.012\right)^t\\\\f(t)=21020\left(1.012\right)^t\\

Starting from t=2002

By putting t=2015-2002=13  we have:

f(t)=21020\left(1.012\right)^{13}\\\\\approx 24546

Determine the value for AB
grin007 [14]

Answer:

x = 2

AB = 14

Step-by-step explanation:

2x(10) = 8(x+3)

20x = 8x + 24

subtract 8x from both sides

12x = 24

x = 2

Check:

4(10) = 8(5)

40 = 40

Correct

2x = 2 x 2 = 4

4 + 10 = 14

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Alex73 [517]

Answer:

<h2>3600</h2>

Step-by-step explanation:

Shift the decimals of both 213480 and 59.3 to the right by 2 decimal places. (This is needed to convert 59.3 to 5930, since long division must divide by a whole number.)

21348000÷5930

Therefore, 213480\div 59.3=3600213480÷59.3=3600.
