<u>Answer:</u>
<h2>
θ ≈ 81.37°</h2>
<u>Explanation:</u>
let the angle the ladder makes with the ground be θ
θ = cos⁻¹(3/20)
θ = cos⁻¹(0.15)
θ ≈ 81.37°
The event by definition that covers the entire sample space of the experiment is;
<em><u>The number is even or less than 12</u></em>
We are given the numbers in the set as;
set {2, 3, 4,... 10}.
Now, the numbers in the set are even and odd numbers from 2 to 10 with 10 being the highest and 2 being the lowest.
Thus the event that covers this sample space is simply a set of numbers that are even or less than 12.

Answer:
a
Step-by-step explanation:
big brain
AX = B
1 -1 -1 x 0
0 -2 -1 y = -2
2 1 0 z -4
x
y = A^-1 B
z
x -1 1 1 0 6
y = 2 -2 -1 . 2 = -8
z -4 3 2 4 14
The answer is 120 what you do you take -10 and multiply it by -12. Why a positive 120 you may ask because when you multiply two numbers with the same sign the answer should be positive no matter what. Hope I helped!
