It will be D by multiplying the numerator and the denominator by the unit rate of 6
Answer:
Step-by-step explanation:
In the model
Log (salary) = B0 + B1LSAT +B2GPA +B3log(libvol) +B4log(cost)+B5 rank+u
The hypothesis that rank has no effect on log (salary) is H0:B5 = 0. The estimated equation (now with standard errors) is
Log (salary) = 8.34 + .0047 LSAT + .248 GPA + .095 log(libvol)
(0.53) (.0040) (.090) (.033)
+ .038 log(cost) – .0033 rank
(.032) (.0003)
n = 136, R2 = .842.
The t statistic on rank is –11(i.e. 0.0033/0.0003), which is very significant. If rank decreases by 10 (which is a move up for a law school), median starting salary is predicted to increase by about 3.3%.
(ii) LSAT is not statistically significant (t statistic ≈1.18) but GPA is very significance (t statistic ≈2.76). The test for joint significance is moot given that GPA is so significant, but for completeness the F statistic is about 9.95 (with 2 and 130 df) and p-value ≈.0001.
Answer:
the answer is true hope it helps
Step-by-step explanation:
Answer:
[0,1] and [-1,0]
Step-by-step explanation:
We have the function to determine consecutive values of x between which each real zero is located we have to replace the function with different values and then analyze the results.
We are going to replace the function with x=0,
Now we are going to replace with x=1,
With x=2,
Now with x=-1,
With x=-2,
We have to analyze:
We have that f(2) and f(1) have the same signs both are negatives this means that there isn't a zero between the interval [1,2].
We have that f(1) and f(0) have opposite signs this means that there is a zero between the interval [0,1].
f(0) and f(-1) have opposite signs too, then there's also a zero in the interval [-1,0].
And finally, f(-1) and f(-2) have the same signs then there isn't a zero in the interval [-2,-1]
The graph of the function shows that the answer is correct:
The shapes are being used instead of variables.
For problem 4; start with clue 2, then clue 3, then clue 4, and lastly do clue 4.
<u>Clue 2</u>
3 · square - 8 = 19
3 · square = 27 <em>added 8 to both sides</em>
square = 9 <em>divided both sides by 3</em>
<u>Clue 3</u>
2 · triangle + 3 = -3
2 · triangle = -6 <em>subtracted 3 from both sides</em>
triangle = -3 <em>divided both sides by 2</em>
<u>Clue 4</u>
square + triangle = 6
(9) + (-3) = 6 <em>substituted solutions from Clue 2 and Clue 3</em>
6 = 6 <em>True statement confirms that Clues 2 & 3 are correct</em>
<u>Clue 1</u>
star + square = 12
star + (9) = 12 <em>substituted solution from Clue 2 </em>
star = 3 <em>subtracted 9 from both sides</em>
Answer: triangle = -3, star = 3, square = 9
For problem 5; do the same thing as problem 4 and start with Clue 2
Answers: triangle = -2, star = 10, square = 8
