TOm earned 173 dollars Last week working for 25 hours.
Now, if you're asking about his earnings, it's 173 dollars.
But if you're asking about his hourly rate.Let's find out:
=> 173 / 25 = 6.92 dollars per hour.
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
Answer:
The probability that a car chosen at random is not red is 75%.
Step-by-step explanation:
Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:
60 = 100
15 = X
15 x 100/60 = X
25 = X
100 - 25 = 75
Therefore, the probability that a car chosen at random is not red is 75%.
I would say the answer is b, because it states -4 + 4 = 0
Answer:
-1/2
Step-by-step explanation:
Subtract the exponents within the parentheses.
0-2 = -2
Then, Raise the answer to the power of -1
-2 ^ -1 ( on a calculator )
