Answer:
The interquartile range is 12.
Step-by-step explanation:
In a box-and-whisker plot, the left edge of the box is the lower quartile and the right edge of the box is the upper quartile. The line dividing the box is the median. The end of the left whisker shows the minimum value. The end of the right whisker shows the maximum value.
In your question, the lower quartile is 29, the upper quartile is 41, while the median is 32. The minimum value is 10 and the maximum value is 51.
The formula for the interquartile range is as follows:
Interquartile Range = Upper quartile - Lower quartile
In this question, interquartile range = 41 - 29 which equals 12. Hence, the answer is 12.

Answer:
p = 2 or p = -2 4/9
Step-by-step explanation:
We can substitute x=3/2 into the equation and solve for the values of p that make the result be zero.
p^2(3/2)^2 -12(3/2) +p +7 = 0
9/4p^2 -18 + p + 7 = 0 . . . . eliminate parentheses
9p^2 +4p -44 = 0 . . . . . . simplify and multiply by 4
(9p +22)(p -2) = 0 . . . . . factor
Values of p that make 3/2 be one of the zeros are ...
p = -22/9, p = 2
_____
<em>Additional comment</em>
The <em>zero product rule</em> tells you a product will be zero if and only if a factor is zero. Hence the solutions to the quadratic are values of p that make the factors zero.
9p +22 = 0 ⇒ 9p = -22 ⇒ p = -22/9
p -2 = 0 ⇒ p = 2
__
For p=2, the solution 3/2 has multiplicity 2. For p=-22/9, the other zero is x=123/242.
What is that supposed to mean? What is the equation needed to solve?
Answer:

if she's driving at 40 miles per hour, that means in 2 hours she will have driven 80 miles plus 30 mins. for another 20 miles. In total - 2h 30mins.
