1. Evaluate a/b + c^2d for a = 6,b=3,c=4,and d=5
1 answer:
Answer:
1) C
2) A
3) D
Step-by-step explanation:
A) We substitute the values for a ,b , c and d in the given equation.
Hence option c. 82 is the answer.
2) The product 6(-3)
Since positive x negative gives negative
we get -(6x3) = -18
Option A is the answer.
3) For this we have to find cube of a fraction with numerator 4 and denominator 7
We find cube of numerator first = 4x4x4 =64
Cube of denominator = 7x7x7 = 343
Hence cube of fraction = 64/343

<h3>Answer: Parallelogram</h3>
You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).
An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram
Side note: The other diagonal is either u-v or v-u depending on your reference point.
Answer:
Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:
Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:
And now we can find using the total probability rul given by:
And if we replace the values given we got:
And that would be the final answer.
