Answer:
Part A:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B: Brand Y has a longer battery life
Step-by-step explanation:
Part A:
Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B:
Brand Y has a higher median value (16) than Brand X (13).
This implies that brand Y has a battery life that last longer than brand X.
Volume of the box= <span>56 cubic inches
let x is the length, then
width =</span><span>2 inches shorter than its length = x - 2
</span>height = <span>3 inches taller than its length = x+3
Volume = length x width x height
56 = x x (x-2) x (x+3)
56 = (x</span>² -2x)(x+3)
56 = x³ +3x² -2x² - 6x
56 = x³ + x² -6x
x³+x²-6x-56 = 0
using the rational root theorem and factoring the polynomial;
(x-4)(x² +5x +14) = 0
from here;
x-4 = 0
x = 4
So, length = 4 inches
width = x - 2 = 4 -2 = 2 inches
length = x + 3 = 4 + 3 = 7 inches
volume = l x w x h = 4 x 2 x 7 = 56
Answer: 60.
Step-by-step explanation: After you divide you get 60.037037. And since were rounding its 60.
