Answer:
d(32) = 28.80
the price Marcus pays on an item with an original price of 32
Step-by-step explanation:
d(32) = 32 -0.1(32)
d(32) = 28.8
The problem statement tells you d(32) is the price Marcus pays when the original price is 32.
Answer:
3/π Hz
Step-by-step explanation:
Recall that for a cos function in the form
y = A cos Bx
period = 2π / B
frequency = 1/period = B/2π
Given y = -5 cos 6x
A = -5 and B = 6
frequency,
= B / 2π
= 6 / 2π
= 3/π
69 out of 100 would be 69/100 = 0.69 = 69% were answered correctly
100% - 69% = 100-69 = 31 = 31% = 31/100 were incorrect
Answer:
But also we can define the variable in terms of like this:
And usually this notation is better since the probability density function is defined as:
Step-by-step explanation:
We know that the random variable X who represents the waiting time to see a shooting star during a meteor shower follows an exponential distribution and for this case we can write this as:
But also we can define the variable in terms of like this:
And usually this notation is better since the probability density function is defined as:
