First you multiply both sides by 10, add 40, divide by 4, then square root
10*(4x^2-40/10)= (36)*10
(4x^2-40)+40=(360)+40
(4x^2)/4=(400)/4
x^2=100
x=10
Answer:
0.149
Step-by-step explanation:
Given that Jason wants to perform a two-tailed test for equality between two independent sample proportions
Each sample has at least 10 "successes" and 10 "failures."
Jason's test statistic is -1.44
Since here proportions are tested Z test might have been used.
Z statistic = -1.44
We can get p value for this Z statistic
p value=0.149
p value for two tailed is 0.149
Comparing this with t statistic we can decide whether to accept or reject null hypothesis.
The answer is 2.7
hope this helps
Answer:
17 units
Step-by-step explanation:
P to Q = (-2,2) to (5,2) = is 7 units
The Q to R = (5,2) to (5,-5) is 7 units
Then R so S = (5,-5) to (8,-5) is 3 units
7+7+3 = 17 units
Answer:
