28-2(9)=?
28-18=10
Answer:
Step-by-step explanation:
To Test :-
H0 :- P = 0.12
H1 :- P ≠ 0.12
P = X / n = 156/800 = 0.195
Test Statistic :-
Z = ( P - P0 ) / ( √((P0 * q0)/n)
Z = ( 0.195 - 0.12 ) / ( √(( 0.12 * 0.88) /800))
Z = 6.5279
Test Criteria :-
Reject null hypothesis if Z > Z(α/2)
Z(α/2) = Z(0.05/2) = 1.96
Z > Z(α/2) = 6.5279 > 1.96, hence we reject the null hypothesis
Conclusion :- We Reject H0
There is sufficient evidence to support the claim that there is a difference.
Answer:
15√2
Step-by-step explanation:
Tan 45° = 1, and tan = (opposite side)/(adjacent side)
We can set up an equation as follows...
tan 45° = x/(15√2)
Solve it...
1 = x/(15√2)
multiply both sides by 15√2 to isolate 'x'
15√2(1) = (15√2)x/(15√2)
15√2 = x ( the 15√2 in the numerator and denominator cancel out)
Equation: 15 + 6t = 81
Work: 15 + 6t = 81
-15 -15
6t = 66
t = 11
