Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price.
60% of x = 2.8
Simply means: 60/100 * x = 2.8
You solve for x, which comes out to $4, which is your original price.
Answer:
17.2
Step-by-step explanation:
4(a+7) + 2a
4(-1.8 + 7) 2(-1.8)
-7.2+28-3.6
-10.8+28
17.2
Answer:C
Therefore: In Quadrant I, cos(θ) > 0, sin(θ) > 0 and tan(θ) > 0 (All positive). For an angle in the second quadrant the point P has negative x
Step-by-step explanation:
Answer: Our required probability is 0.175.
Step-by-step explanation:
Since we have given that
Average of 5 e-mails messages per day.
so,
We need to find the probability that on a randomly selected day your professor will have 5 messages.
Let X be the number of messages in poisson distribution.
So, P(X=5) is given by
Hence, our required probability is 0.175.
