lina2011 [118]

Answer:

The greatest amount of fizzy drink he can make is 480 ml

Step-by-step explanation:

The ingredients for a fizzzy drink is 5 parts lime juice and 3 parts lemonade

Therefore, we have a total portion of 5 + 3 = 8 parts

Since there ar more parts of lime juice per fizzy drink, we calculate based on lime juice

Also dividing the proportions by we get

5/5 part lime juice and 3/5 parts lemonade or

1 part lime juice and 3/5 parts lemonade or

Thus we have 300 ml lime juice and 3/5× 300 ml lemonade or

300 ml lime juice and 180 ml lemonade = 480

The greatest amount of fizzy drink he can make = 480 ml.

A pan of lasagna cut into 100 servings is equally shared among a group of people. For Exercises
Volgvan

53).  100 servings / 20 people  =  (100/20) (svngs/ppl)

                                                 = 5 servings per person.

         Each person gets 1/20 = 5% = 0.05 of the pan.


54).  100 servings / 40 people  =  (100/40) (svngs/ppl)

                                                 = 2.5 servings per person.

         Each person gets  1/40 = 2.5% = 0.025 of the pan.


55).  100 servings / 30 people  =  (100/30) (svngs/ppl) 

                                                  = (3 and 1/3) servings per person.

         Each person gets  1/30 = (3 and 1/3) % = 0.0333... of the pan.

Let n1=50​, X1=10​, n2=50​, and X2=30. Complete parts​ (a) and​ (b) below. a. At the 0.10 level of​ significance, is there evide
iren2701 [21]

Answer:

|Z| = |-4.089| > 1.645 at 0.10 level of significance

Null hypothesis is rejected at  0.10 level of significance

<em>There is a difference between the two Population proportions</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given first sample size (n₁)  = 50

Given  proportion of the first sample p⁻₁= 0.2

Given second sample size (n₂)  = 50

Given proportion of the second sample p₂⁻ = 30/50 = 0.6

<em>Null Hypothesis : H₀: p₁⁻=p₂⁻</em>

<em>Alternative Hypothesis : H₁: p₁⁻≠p₂⁻</em>

<u><em>Step(ii):-</em></u>

Z-statistic

             Z = \frac{p_{1} -p_{2} }{\sqrt{pq(\frac{1}{n_{1} } +\frac{1}{n_{2}) } } }

Where

         P = \frac{n_{1}p_{1} +n_{2}  p_{2} }{n_{1} +n_{2} }

        P = \frac{50X0.2+50X0.6}{50+50} = 0.4

<em>Z-statistic</em>

       

      Z = \frac{0.2-0.6}{\sqrt{0.4 X 0.6(\frac{1}{50}+\frac{1}{50}  } }

     Z =  -4.089

Level of significance =0.10

Z₀.₁₀ = 1.645

|Z| = |-4.089| > 1.645 at 0.10 level of significance

Null hypothesis is rejected at  0.10 level of significance

<u><em>Final answer</em></u>:-

<em>There is a difference between the two Population proportions</em>
