A project is found to have expected time T = 35.33 days and variance V = 3.22.

Goryan [66]

Answer:

a) $z = \frac{40-35.33}{1.794}= 2.60$

b) $z = \frac{40-35.33}{1.794}= 2.60$

c) $z = \frac{30-35.33}{1.794}= -2.97$

Step-by-step explanation:

For this case we know that the mean for the random variable of interest is $\mu = 35.33$ and the variance $\sigma^2 = 3.22$ so then the deviation would be $\sigma = \sqrt{3.22}= 1.794$

The z score is given by thsi formula:

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

Part a

We want this probability:

$P(X>40)$

And if we find the z score we got:

$z = \frac{40-35.33}{1.794}= 2.60$

And we can find this probability: $P(Z>2.60)$

Part b

We want this probability:

$P(X$

And if we find the z score we got:

$z = \frac{40-35.33}{1.794}= 2.60$

And we can find this probability: $P(Z$

Part c

We want this probability:

$P(X$

And if we find the z score we got:

$z = \frac{30-35.33}{1.794}= -2.97$

And we can find this probability: $P(Z$

James sold 450 tickets for the community play. Tickets for children cost $2, and tickets for adults cost $5. James sold $1,800 w

nlexa [21]

Answer:

James sold 300 tickets for adults

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of tickets sold by James = 450

Cost of a child ticket = $ 2

Cost of an adult ticket =$ 5

Amount of money collected by James after selling the 450 tickets for the community play = $ 1,800

2. How many tickets for adults did James sell?

x = Number of adult tickets James sold

450 - x = Number of children tickets James sold

For solving for x, we write this equation:

5x + 2 * (450 - x) = 1,800

5x + 900 - 2x = 1,800

3x = 1,800 - 900

3x = 900

x = 900/3 = 300

450 - x = 450 - 300 = 150

James sold 300 tickets for adults and 150 for children
