Step-by-step explanation:

<em>Given</em><em>, </em>

<em>a</em><em> </em><em>student</em><em> </em><em>(</em><em>Charles</em><em>)</em><em> </em><em>bought</em><em> </em><em>a</em><em> </em><em>car</em><em> </em><em>and</em><em> </em><em>sold</em><em> </em><em>it</em><em> </em><em>in</em><em> </em><em>1</em><em>5</em><em> </em><em>%</em><em> </em><em>profit</em><em> </em><em>for</em><em> </em><em>$</em><em>4</em><em>6</em><em>6</em><em>9</em><em>.</em>

<em>we</em><em> </em><em>have</em><em> </em><em>the</em><em> </em><em>formula</em><em>, </em>

<em>cp =  \frac{sp \times 100}{100 + p\%}</em>

<em>so</em><em>,</em><em> </em>

<em>cp =  \frac{4669 \times 100}{100 + 15}</em>

<em>by</em><em> </em><em>simplifying</em><em> </em><em>it we</em><em> </em><em>get</em><em>, </em>

<em>CP</em><em> </em><em>is</em><em> </em><em>$</em><em>4</em><em>0</em><em>6</em><em>0</em><em>.</em>

<em>Therefore</em><em>, </em><em> </em><em>the</em><em> </em><em>cp</em><em> </em><em>was</em><em> </em><em>$</em><em>4</em><em>0</em><em>6</em><em>0</em><em>.</em>

A media poll of 500 air travelers surveyed in national airports found that 370 favor tighter security procedures in boarding pla
serg [7]

Answer:

92% Confidence interval:  (0.7078,0.7722)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 500

Number of travelers who favor tight security, x = 370

\hat{p} = \dfrac{x}{n} = \dfrac{370}{500} = 0.74

92% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.08} = \pm 1.645

Putting the values, we get:

0.74\pm 1.645(\sqrt{\dfrac{0.74(1-0.74)}{500}}) = 0.74\pm 0.0322\\\\=(0.7078,0.7722)

James makes fruit punch by mixing fruit jucie and lemonade in the ratio 1:4 she needs to make 40 liters of punch for a party How
Andrews [41]

Answer:

Part 1.

Juice = 8 L.

Lemonade = 32 L.

Part 2.

20 L punch Josie can make.

Part 3.

New ratio juice : lemonade = 2 : 9

Step-by-step explanation:

Part 1.

1+4 = 5 parts altogether, 1 parts for juice and 4 parts for lemonade.

40 : 5 = 8 L is 1 part.

Juice - 1 part - 8 L.

Lemonade - 4 parts - 4*8 = 32 L.

Part 2.

1 parts of juice needs 4 parts of lemonade

4 L of juice     needs  x L of lemonade

1 : 4 = 4 : x

x = 4*4/1 = 16 L lemonade

4+ 16 = 20 L punch Josie can make

Part 3.

It was 4 L of juice and 16 L of lemonade.

After 2 L lemonade was added, we have 4 L of juice and (16+2) = 18 L of lemonade.

4 L juice : 18 L lemonade = 4/2 L juice : 18/2 L lemonade =

= 2 L juice: 9L lemonade

New ratio juice : lemonade = 2 : 9

OlgaM077 [116]

Answer: d) $369.31 to $380.69

Step-by-step explanation:

Given;

Mean price x= $375

Standard deviation r= $20

Number of retail stores n = 50

Confidence interval of 95%

Z*(95%) = 1.96

Confidence interval = x+/-Z*(r/√n)

= $375+/- 1.96(20/√50)

= $375+/- 5.69

Confidence interval = ($369.31 to $380.79)
