Answer:
3. 1/28
4. About 7.11%
Step-by-step explanation:
3.
Since two of the eight ads are by a local retailer, the probability of picking either one once is 2/8=1/4. However, the second time, since on of the ads has already been used and there are a total of 7 left, the new probability is 1/7. Multiplying these two together, you get 1/4*1/7=1/28.
4.
To find the probability, you need to find the area of the smaller triangle and the rest. The formula for the area of an equilateral triangle is , meaning that the area of the big triangle is and the area of the little triangle is . . Hope this helps!
Answer:
0.00335
Step-by-step explanation:
Probability that one of the components works for x hours before failing is given by
f(x) = 2e⁻²ˣ
We can then find the probability that one of the components works for x = 4 hours before failing
f(x) = 2e⁻⁸ = 0.0006709253
Probability that the system works for 4 hours = probability that at least 1 of the components of the system works for 4 hours =
1 - (Probability that none of the components of the system works for 4 hours)
Probability that one of the components doesn't work for 4 hours = 1 - 0.000670925 = 0.9993290747
Probability that none of the 5 components work for 4 hours = (0.9993290747)⁵ = 0.9966498721
Probability that the system works for 4 hours = probability that at least 1 of the components of the system works for 4 hours
= 1 - (Probability that none of the components of the system works for 4 hours)
= 1 - 0.9966498721 = 0.0033501279

Answer:
so i do not have that many resources like how fast she can read, how many pages there are, and how many words are on the page
Step-by-step explanation:
if she is and older person than i can say 25 pages in 13 or 14 minutes but if she is younger than i can say 20 or 22 minutes i hope this helps with your problem
The proportional equation for the the number of gallons of yellow paint, y needed for any amount of blue paint, b is:
<h3>Proportional equation:</h3>
- A <em>proportional equation</em> is modeled by:
- In which a is the constant of proportionality.
In this problem, the parameters are:
- of a gallon of blue paint, hence
- of a gallon of yellow paint, hence .
Then, to find the constant of proportionality:
Hence, the equation is:
