No (3,6) is the solution for the first equation only
When I did it I got 140296.11541307
Answer:
The probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a person lives in a mobile home.
<em>Y</em> = a person dies as a result of tornado.
Given:

Compute the value of
as follows:

Compute the probability that a person dies as a result of tornado as follows:

Then the probability that a person does not dies as a result of tornado is:

Compute the value of
as follows:

Thus, the probability a person will not live in a mobile home if they do not die as a result of the tornado is 0.9265.
Step 1: Add 9 to both sides
Step 2: Combine like terms (notice the -9 and 9 cancel out)
Step 3: Flip the inequality
-16 > x - 9
-16 + 9 > x - 9 + 9 ... apply step 1
-7 > x ... apply step 2
x < -7 ... apply step 3
The final answer is x < -7
Any value smaller than -7 will work as a solution
Answer:
Step-by-step explanation:
Given that the weight of a candy bar X is N(mean = 50 gm, 2 = sigma)
Packs of 4 bars
n = sample size = 4
Std error of sample = sigma/sqrt n = 1
P(Mean diff > 4 gms) = P(Z>4/Se ) = P(Z>4)
=0.0000
Hence it is an impossible event
Option A
(A) It is extremely unlikely for this to occur; the probability is very close to 0.
