4 units down => y - 4
3 units left => x - 3
=> C
Here is our inequality.

Let's go from least to greatest, and add in infinity as our maximum.

Our interval notation would look like this.

We put the lower bound, then the higher bound, using brackets instead of parentheses if x can also be equal to that value.
Answer:
a) 20 second
b) 20 second
c) 1 minute
Step-by-step explanation:
Let X be the exponential random variable arising from the Poisson process with the rate λ = 3 counts per minute. Its cdf is then given by:
F(x) = I - e^-3x, x >= 0
Calculate the mean and the standard deviation of the random variable X as follows:
Е(X) =I/λ =I/3=20 second
std (x) =√1/λ^2=1/3=20 second
For the part c), write down the equation:
0.95 = P(X < x) = F(x) = I - e^-3x
and solve the equation for x to obtain:
x = -1/3 In 0.05 = 0.9985 ≅ 1 minute
Answer:h=1
Step-by-step explanation:
If N = 8
if M = 7
then the equation is 8(2) - 7
do the multiplication first 8(2) = 16
now do the subtraction 16 - 7 = 9
