Answer:
B : both containers are 50
Step-by-step explanation:
Since water in container 2 is in higher temp, it will transfer some of its heat to container 1 until both the containers reach same temperature. This is the concept of equilibrium that mother nature abides by.
Answer:
Step-by-step explanation:
Hello, first we can develop (x+a)(x+b)
We know that this should be equal to
So, we can identify the coefficients of the like terms
1 = 1 (terms in
1 = a + b (terms in x)
-72 = ab (constant term)
72 is 8 * 9 so, -72=9*(-8)
and we have 9 - 8 =1
so, a = 9 and b = -8
Thank you
Answer:
Now we can find the p value with the following probability:
Step-by-step explanation:
Information given
n=97 represent the random sample taken
estimated proportion of defective
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to tests
We want to tet if the true proportion is less than 6%, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can find the p value with the following probability:
