Answer:
No solution.
Step-by-step explanation:
(1/12)^-2b * 12^(-2b + 2) = 12
1/12 is basically the same thing as 12^-1.
12^(-1 * -2b) * 12^(-2b + 2) = 12
12^2b * 12^(-2b + 2) = 12
12^(2b - 2b + 2) = 12
12^2 = 12
Since the answers don't match up, the answer will be no solution.
Hope this helps!
It’s D explanation: it’s d
Answer:
<u>always</u>
Step-by-step explanation:
For this hypothesis test:
<u>The Decision rule: </u> To reject the null hypothesis 
if the p-value is lesser than < the significance level.
At the level of significance 0.01, the null hypothesis is rejected.
So, p-value < 0.01 and this typically shows that p-value is < 0.05.
Therefore, it will <u>always</u> be rejected at ∝ = 0.05
Answer:
The 5th term is 16
Step-by-step explanation:
Given data
a= 12
say we want to find the fifth term
n=5
d= 1
The expression for the nth term given as
an = a + (n – 1) × d
Substitute
an= 12+(5-1)1
an= 12+4
an= 16
Answer:
(2, - 3)
Step-by-step explanation:
given the 2 equations
5x + 3y = 1 → (1)
7x + 3y = 5 → (2)
multiply all terms in (1) by - 1
- 5x - 3y = - 1 → (3)
add (2) and (3) term by term to eliminate the term in y
(7x - 5x) + (3y - 3y) = (5 - 1)
2x = 4 ( divide both sides by 2 )
x = 2
Substitute x = 2 in either (1) or (2) for corresponding value of y
(2) : 14 + 3y = 5 ( subtract 14 from both sides )
3y = - 9 ( divide both sides by 3 )
y = - 3
solution is (2, - 3)
