Answer:
66.6% or 0.66
Step-by-step explanation:
82% or 0.82 of All households have cable TV.
X = The number of households in a group of 6, that have cable TV.
You wish to find the proportion or percentage of groups for which EXACTLY 4 of 6 households will have cable TV.
82% of 6 is = 4.92
Approximately 4.92 out of 6 households, have cable TV.
Using this figure, you can now find out what % of 6 will give you 4.
Cross multiply:
0.82 - 4.92
M - 4
M = (4×0.82) ÷ 4.92 = 3.28÷4.92 = 0.666
Hence, 66.6% of 6 households, have cable TV. In other words, exactly 4 households (X=4) have cable TV.
To test, you can find what 66% of 6 is. You will get 4.
Answer:
12:39
Step-by-step explanation:
First, to make it easier, round the amount of time the movie lasts to the nearest hour. In this case, the movie "lasts" for 2 hours.
Add 2 hours to 10:40am. Note that when it hits 12, the am becomes pm.
10:40 + 2:00 = 12:40
Now, subtract 1 minute from the amount (1 hr 60 min - 1 hr 59 min = 1 min)
12:40 - 0:01 = 12:39
12:39 pm should be the time the movie ends.
