Answer: 0.3741
Step-by-step explanation:
Poison probability ;
P(x) = [U(^x) e(^-U)] ÷ x!
Where U = mean
Note: e = exponential symbol
Number of checks that year = 171
Number of days in a year = 365
U = 171/365 = 0.468
Average checks per day = 0.4685
Probability that at least one check was written per day is can be calculated by;
P(not 0) = 1 - P(0)
Therefore,
P(x) = [U(^x) e(^-U)] ÷ x!
P(0) = [ 0.4685^0 * e^-0.4685] ÷ 0!
P(0) = [ 1 * 0.6259] ÷ 1
P(0) = 0.6259
Therefore,
P(not 0) = 1 - 0.6259 = 0.3741
X-8+y^2=52 is the answer I believe

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:
The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set 
. In other words, we define the y-intercept (let's call it 
as:
Setting in our function we have:
So <em>in this context the y-intercept is -16</em>
