If I said I had .25 cents you would know I had a quarter of a dollar or 1/4th of a dollar, .25 cents could also be thought of as 25% of a dollar.
so in this case if the "dollar" is x and the "quarter" is .88 you could say you have 88% of x
8:5 you divide 8 by 8 and 5 by 8 to see how long he spent on each pie:
which is 0.625 and 1: 0.625 which is 1 minute and 36 seconds
Answer:
Step-by-step explanation:
In a direct proportion,
Pressure = constant × temperature
p = kT
We can use the initial conditions to find the value of k, and then calculate the pressure at the new temperature.
1. Determine the value of k
Data:
p₁ = 6 lb·in⁻²
T₁ = 440 K
Calculation:
2.Calculate the new pressure
Answer:
25 acute
Step-by-step explanation:
Step-by-step explanation:
that is quite a lot of failing TVs.
if 5% are failing, this means you have a "chance" of 5/100 = 1/20 that your TV is among them.
that means the expected costs for replacement in the next 3 years are
1750 × 1/20 = 175/2 = $87.50
minus the $200 replacement plan the expected value is of course negative :
87.5 - 200 = -$112.50
and if your TV breaks after more than 3 years, the expected value is actually -1750 - 200 = -$1,950
which is the principle of replacement plans, and why I never buy one.
but sure, for the 5% with broken TVs this pays off big time (it is kind of a lottery).
