Answer:
- 864
Step-by-step explanation:
In the case of a 2 × 2 matrix the determinant may be defined as:
|A| = = ad-bc
Given in the question a matrix
(-30)(30) - (-6)(6)
-900 + 36
- 864
Recall all of the trigonometric properties (SOH CAH TOA)
Your angle of interest is 80° so you'd have to find a relationship between d and the angle of interest.
You know it's a right angle triangle because it's the perpendicular distance (height) to the ground, and it always forms a right triangle.
The tangent function does not need to worry about the hypotenuse, so you'd instinctively use the tangent function. Tangent function is opposite/adjacent, so
Answer:
The missing probability is, P (X = 7) = 0.24.
Step-by-step explanation:
The complete question is:
A psychology experiment on memory was conducted which required participants to recall anywhere from 1 to 10 pieces of information. Based on many results, the (partial) probability distribution below was determined for the discrete random variable (X = number of pieces of information remembered (during a fixed time period)).
What is the missing probability P(X=7)? Your answer should include the second decimal place.
X = # information | probability:
1 | 0.0
2 | 0.02
3 | 0.04
4 | 0.07
5 | 0.15
6 | 0.18
7 | ?
8 | 0.14
9 | 0.11
10 | 0.05
Solution:
The sum of the probabilities of all events of an experiment is always 1.
Use the above theorem to compute the missing probability.
Thus, the missing probability is, P (X = 7) = 0.24.
Hi there.
4(2 + 3i) - 2(6 - 8i); apply the distributive property.
8 + 12i - 12 - 16i; combine like-terms.
-4 - 4i is your final expression.
I hope this helps!
