Step-by-step explanation:
Given
See attachment for complete question
Required
From the attachment, we have:
---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.
5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:
The probability is then calculated as:
This gives
Answer:
i wanna say its 136 but im not completely sure
We need a picture of the lines
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
