Find the indicated limit, if it exists. limit of f of x as x approaches 0 where f of x equals 7 minus x squared when x is less t
hram777 [196]

Answer:

answer is 7

Step-by-step explanation:

We are given a piecewise function which has a split at x=0

f(x) = f(x) = 7-x^2, x0

To find the limit, we have to find here left hand limit and right hand limit separately.

Here left hand limit for x tending to 0 is

limit of 7-x^2 as x tends to 0

= 7-0 = 7

Right limit = limit of 10x+7 as x tends to 0

=10(0)+7 = 7

Since right hand limit = left hand limit we have

there exists a limit for x=0 and the limit is 7

What is the probability that the system does not have a type 2defect?b.What is the probability that the system has both type 1 a
Lana71 [14]

Answer:

a.  0.93 b. 0.06 c. 0.05

Step-by-step explanation:

Probability is commonly known as the chance of success of a particular event. The probability of failure of the event can also be estimated.

(a) Probability of not having type 2 defect is: P(A_{2}^{'})  = 1 - P(A_{2}) = 1 - 0.07 = 0.93

(b) Probability of having type 1 and 2 defects is: P(A_{1} n A_{2}) = P(A_{1}) + P(A_{2}) - P(A_{1}U A_{2}) = 0.12 + 0.07 - 0.13 = 0.06

(c) probability pf having both type 1 and type 2 defects but not type 3 defect is:

P(A_{1} + A_{2} + A^{'} _{3}) = P(A_{1} n A_{2}) - P(A_{1} n A_{2} n A_{3}) = 0.06 - 0.01 = 0.05
