Montano1993 [528]

Answer:

$P(0.0014 < x < 0.0026) = 0.86639$

Step-by-step explanation:

Given

$\mu = 0.002$

$\sigma = 0.0004$

Required

$P(0.0014 < x < 0.0026)$

First, calculate the z score

$z = \frac{x - \mu}{\sigma}$

For x = 0.0014

$z = \frac{0.0014 - 0.002}{0.0004}$

$z = \frac{-0.0006}{0.0004}$

$z = -1.5$

For x = 0.0026

$z = \frac{0.0026 - 0.002}{0.0004}$

$z = \frac{0.0006}{0.0004}$

$z = 1.5$

So, we have:

$P(0.0014 < x < 0.0026) = P(-1.5$

From z probability table, we have:

$P(-1.5$

Hence:

$P(0.0014 < x < 0.0026) = 0.86639$

The admission fee at a carnival is 3.00 for children and $5.00 for adults. On the first day 1500 people enter the fair

Natasha2012 [34]

Question:

The admission fee at a carnival is $3.00 for children and $5.00 for adults. On the first day 1,500 people enter the fair and $5740 is collected. How many children and how many adults attended the carnival?

Answer:

Number of children and adults attended the carnival are 880 and 620 respectively

Step-by-step explanation:

Given:

The admission fee at a carnival for children = $3.00

The admission fee at a carnival for adults = $5.00

Number of people entered the fare on first day= 1500

Total amount collected on the first day = $5740

To Find:

Number of children and adults attended the carnival =?

Solution:

Let

The number of children be x

The number of adults be y

The we know that on the first day the total number children visited the fare was 1500

x + y = 1500

x = 1500 - y------------------------------(1)

Also the total fare collected was $5740

x(3) + y(5) = 5740

3x + 5y = 5740-------------------(2)

Substituting (1) in (2),

3 (1500 - y) + 5y = 5740

4500 -3y + 5y = 5740

-3y + 5y = 5740 - 4500

2y = 1240

$y = \frac{1240}{2}$

y = 620 adults

From 1 ,

x = 1500 - 620

x =880
