Answer:
The magnitude of the resultant force is:

The direction is:

Step-by-step explanation:
Let's find the components of each vector is x and y-directions first.
<u>Sum of x-component vector forces.</u>



<u>Sum of y-component vector forces.</u>


The magnitude of the resultant force is:


The direction is:

Answer:
(E) None of these above are true.
Step-by-step explanation:
Married = 74% or 0.74
College graduates = 42% or 0.42
pr(married | college graduates) = 0.56
(A) These events are pairwise disjoint. This is false. Pairwise disjoint are also known as mutually exclusive events. Here we can see that both events are occurring at same time.
(B) These events are independent events. This is also false.
(C) These events are both independent and pairwise disjoint. False
(D) A worker is either married or a college graduate always. False
Here Probability(A or B) shall be 1
= Pr(A) + Pr(B) - Pr( A and B) = 0.74 + 0.42 - 0.56 * 0.42 = 0.9248
This is not equal to 1.
(E) None of these above are true. This is true.
Answer:
2×(1+10)
Step-by-Step
You are just substituting in where the parenthesis go.
But I am not entirely sure.
