Step-by-step explanation:
Attached the solution and work.
It is true that they are congruent.
Side JK and PM are congruent to each other
JK = 25
PM is divided into two measurements=19 and 6.
So PM is 19 + 6 = 25
Therefore JK = PM
Answer:
2.083 < µ1 - µ2 < 5.917
Step-by-step explanation:
We will need to construct a 90% confidence interval for the difference of 2 means where the populations are normally distributed, and their variances are equal.
The calculations of the sample means and standard deviations are done for us.
Sample 1: Catalyst 1
n = 12, x = 85, s = 4
Sample 2: Catalyst 2
n = 10, x = 81, s = 5
See attached photo for the construction of the confidence interval...
It would be D. because the volume of a sphere is 4/2 x pi x radius^3.
