Answer:
Ok I look now what
Step-by-step explanation:
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
Answer:
See below.
Step-by-step explanation:
Using the Rational Roots Theorem:
Factors of 3: 1, 3 ( = p).
Factors of 6: 1,2,3,6 ( = q).
Possible real roots are a 1 or 3 from p / q = +/- 1/1, +/- 3/1 , +/-1/2, +/- 1/3 , +/- 1/6, +/- 3/2.
The correct answer is C. The interquartile range shows us how the middle 50% (from the 25th to the 75% percentile) of the data is spread out.
= log ( 14/3 * 11/5 ) / (22/15) = log 7 = 0.8451
