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.
Probability =
(number of ways it can come out the way you want it to)
divided by
(total number of ways it can come out).
Total number of ways it can come out =
number of bottles in the cooler
= (10 + 15 + 13) = 38 .
Number of ways it can come out the way you want it to =
(soda + lemonade)
= (10 + 15) = 25 .
Probability of coming out the way you want it to =
25 / 38 = about 65.8 % .
Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
We use the pythagorean theorem and information about the rectangular prism to find the length of the hypotenuses that the spider walks along. Adding them together (5.39+5+5.83+3.91) gives us 20.13cm, the answer.
