Answer:
1/2
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.
(I have highlighted these in yellow).
Therefore, P(X>9) = 8/16 = 1/2
Answer:
The homeowner will require 9 strips of wallpaper.
Step-by-step explanation:
The question is asking <em>"how many 20 inches fit into 15 feet?".</em>
We know that
1 foot = 12 inches;
therefore, 15 feet will be
15 ft * 12 in/ft = 180 in.
Now, the number of 20 inches wallpaper strips that will fit into 180 in long wall will be
180 in/ 20 in = 9
Therefore, the homeowner will require 9 strips of wallpaper.

Hello,
x^3+7x^2+10x-6=x^3+3x^2+4x^2+12x-2x-6
=x²(x+3)+4x(x+3)-2(x+3)
=(x+3)(x²+4x-2)
=(x+3)(x+2-√7)(x+2+√7)
zeroes={-3,-2+√7,-2-√7}
