Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

D. To estimate the probability of observing a value as extreme as p-hat given p
Explanation:
This is the purpose of hypothesis testing in general. The question is always: given the population parameter, what are the chances of observing the sample statistic?
Answer:
1.6 jumps/seconds.
Explanation:
Given the following data;
Total number of jumps = 144 jumps
Time = 90 seconds
To find the average jump rate;
Substituting into the formula, we have;
Average jump rate = 1.5555 ≈ 1.6 jumps/seconds.
