Answer:
The order of operations requires that all multiplication and division be performed first, going from left to right in the expression.
Step-by-step explanation:
Answer:
<u>Alternative Hypothesis:H₁:</u><em> μ ≠ 0.41</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the newscast reaches 41% of the viewing audience in the area
The mean of the Population = 0.41
Given that In a survey of 100 viewers, 36% indicated that they watch the late evening news on this local CBS station
Given that the mean of the sample = 0.36
<u><em>Step(ii):-</em></u>
<u><em>Null hypothesis:</em></u><em> The sample statistic does not differ significantly from the hypothetical parameter value.</em>
<em>Given data </em>
<em>Null hypothesis: H₀ : μ = 0.41</em>
<u>Alternative Hypothesis:</u><em> Any hypothesis which is complementary to the Null hypothesis</em>
<u>Alternative Hypothesis:H₁:</u><em> μ ≠ 0.41</em>
<em> </em>
Z = 7
As given,
19 = z + 12
19 - 12 = z
7 = z
z = 7
Answer: (0,29)
Good luck !
Answer:
The first equation should be multiplied by - 7 and the second equation by 3
Step-by-step explanation:
Given
-- (1)
-- (2)
Required
How to eliminate y
In (1), the coefficient of y = 3
In (2), the coefficient of y = 7
Multiply the first equation by -7
--- (3)
Multiply the second by 3
-- (4)
Add the results together:
<em>See that y is eliminated</em>
