On average, indoor cats live to 14 years old with a standard deviation of 2.5 years. Suppose that the distribution is normal. Let X=the age at death of a randomly selected indoor cat. Round all numeric answers to 2 decimal places. A. X ~ N( , ) B. Find the probability that an indoor cat dies when it is between 15 and 18 years old.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

i believe so, according to my "strange" way of figuring out weird math problems like this.
