Step-by-step explanation:
y =kx(where k is constant)
18 = 6k
divide both side by 6
k = 6
The relationship between x and y
y = kx
y =3x

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>
<span>Answers:
V = (15-2x)(8-2x)x
V = 120x -46x²+ 4x³
V' = 120 -92x + 12x²
0 = 120 -92x + 12x²
x = (92±52)/24
x = 6 or 5/3
Pick x = 5/3
Volume = (15-2*5/3)(8-2*5/3)*5/3
= 90.74 inÂł
To justify x = 5/3 is the max
V" = -92 + 24x
V"(5/3) = -92 + 24(5/3) <0 negative.
Volume V(5/3) is max because the function is
concave down with V"<0.</span>
