Answer:
2827.4ft.^3
Step-by-step explanation:
Volume of a Cone:
V = πr^2 h/3
V = π·15^2·12/3
= 2827.43339
Rounded to the nearest tenth = 2827.4ft.^3
Hope this helps :)

Answer:
36% probability that she will find an acceptable house in the first two weeks that she looks.
Step-by-step explanation:
For each house, there is a 20% probability of it being acceptable. And a 100-20 = 80% of not being acceptable
What is the probability that she will find an acceptable house in the first two weeks that she looks (round off to second decimal place)?
She only looks one house a week.
So this is the same as the probability of taking two or less weeks to find a house.
The are two outcomes
Finding an acceptable house in the first week, with 20% probability
Not finding an acceptable house in the first week, with 80% probability, and then finding an acceptable house in the second week, with 20% probability.
Probability:

36% probability that she will find an acceptable house in the first two weeks that she looks.
Answer:
B
Step-by-step explanation:
-3 < 2x + 3 <= 5
-6 < 2x <= 2
-3 < x <= 1
such a condition is an "and" condition. both parts need to be fulfilled.
-3 < x and x <= 1
if you are still not seeing it :
-3 < x is the same as x > -3
now you see that B is the right answer.
x > -3 and x <= 1
