Answer:
x= 5/4 + −1/4√17 or x = 5/4 + 1/4√17
Step-by-step explanation:
To convert to slope-intercept form, we need to get the y by itself.
First add 3x to both sides to get 3y = 3x + 9.
I put the x term first because in slope-intercept form or y = mx + b form,
the x term will always come before the constant term.
Now divide both sides by 3 to get y = x + 3.
Answer:
Step-by-step explanation:
Given the following :
Single policy holders (n1) = 900
Number making claims (x1) = 135
Married Policy holders (n2) = 400
Number making claims (x2) = 24
α = 0.05
a. Use a level of significance α = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
Null: p1 - p2 = 0
Alternative : p1 - p2 ≠ 0
p = (n1p1 + n2p2) / n1 + n2 ;
p1 = x1/n1 = 135 / 900 = 0.15
p2 = x2/n2 = 24 / 400 = 0.06
p = (900*0.15 + 400*0.06) / (900 + 400)
p = 0.1223076
Test statistic (z):
(p1 - p2) / √p(1-p)(1/n1 + 1/n2)
(0.15 - 0.06) / √0.12231(1-0.12231)(1/900 + 1/400)
= 4.5710979
Decision:
Reject Null if P < α
Obtaining p value from z score using calculator :
P value = 0.0001
0.0001 < 0.05
Hence,
Reject Null
Answer:
Hello, from my calculations, this equation does not have a solution.
Step-by-step explanation:
-2(3x-1) = (-6x) - 1
-6x + 2 = -6x - 1
*+6x from the left side and +1 from the right side*
0=3
0=3 is incorrect and invalid. Plus, in the process of solving for x, the x variable was eliminated.
