Answer: k=1
Step-by-step explanation:
4 - 2k = 2
If it's easier you can also write it like
-2k + 4 =2
Solve for k by isolating it. Move four and then divide the -2.
-2k =2-4
-2k= -2
k= -2/-2
k=1
Answer:
33/4 or 8 1/4
Step-by-step explanation:
-1/2=-2/3x + 5
-5 -5
---------------------
-11/2= -2/3x
____ _____
-2/3 -2/3
---------------------
33/4 = x
Check:
-1/2 = -2/3(33/4) + 5
-1/2 = -11/2 + 5
-1/2 = -1/2
Answer:
6 AND 12
Step-by-step explanation:
3 x 2 = 6
3 x 4 = 12
Answer:
There is a 99% probability that at least one of the intervals will cover the true mean yields at their location
Step-by-step explanation:
In a 90% confidence interval of the mean of a population, there is a 90% probability that it cover the true mean of the population.
What is the probability that at least one of the intervals will cover the true mean yields at their location?
This is 1 subtracted by the probability that none of them cover the true mean yields at their location.
For each one, there is a 10% probability that it does not cover the mean. So the probability that both do not cover the mean is 
The probability that at least one of the intervals will cover the true mean yields at their location is 1-0.01 = 0.99 = 99%.
