The probability that the dealership will wait at least 6 months until the next claim is solved by:We know that the mean number of occurrences per time unit is 0.1, then let’s denote this by λ
So: f (x) = 1 – e ^ -λx for x > 0
P (x > 6) = e^ -x
= e ^-0.1 * 6
= 0.5488

Find the slope and y-intercept of the line. 18x + 4y = 112
yan [13]
To find the slope and y-intercept, you can convert the linear equation into the form y = mx + b, where m is the slope and b is the intercept.
To do so, just simplify for y.
18x+4y=112
4y=-18x+112
y = - \frac{18}{4}x+28
So, the y-intercept is (0, 28) and the slope is 4.5.
Hope that helps!
