Answer:
See below
Step-by-step explanation:
Not sure which answer it is because it did not translate well
(2 1/4 ) / (-2/3) = (9/4) / ( -2/3) = 9/4 * (-3/2) = -27/8 <====maybe your answer is in there somewhere?
Answer:
C 210
Step-by-step explanation:
To solve this, First we must take 42/3, Since it equals 14, we take 15x14 and find 210
(edit: to solve for Kim's missing values, you do the same with 2 and 32)
7/8=0.875
0.875 x 40= 35
Therefore, Kris has finished 35 questions.
Hope this helps.
Answer:
($2.123 ; $2.149)
Step-by-step explanation:
The prediction interval is expressed as :
Predicted value ± standard Error
Predicted value = $2.136
Standard Error = $0.013
Prediction interval :
Lower boundary = $2.136 - $0.013 = $2.123
Upper boundary = $2.136 + $0.013 = $2.149
($2.123 ; $2.149)
B.) The prediction interval provides a range for which the predicted value or price should fall Given a certain degree of probability. If the true value falls within this interval, then, our prediction would be deemed to have occurred not by chance.
Since the actual price within the predicted price interval, then I agree with the judge's Decison that the price was not artificially depressed.
