Answer:P(male | buys lunch) = 0.4 and P(male) = 0.3.

Step-by-step explanation:

There are 46+176 = 222 males.

There are 254+264 = 518 females.

There are a total of 740 people.

The probability of being male is 222/740 = 0.3

There are 46+254 = 300 people that bring lunch.

There are 176 + 264 = 440 people that buy lunch.

P(male | buy lunch) = 176 / 440 = 0.4

P(male | buys lunch) = 0.4 and P(male) = 0.3.

A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much
Rufina [12.5K]

Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

V=a^2\frac{h}{3}

So its just:

8.8^2\frac{12.5}{3} = 322.67 cm^3

Then you just multiply the volume by the cost per cubic centimetre:

322.67cm^3*$0.12=$38.704

After just multiply the cost of one by how many you want, which is 6:

38/704*6=232.32

Mia has 1/2 of a pizza. She divides it equally among 4 people. Which model shows the fraction of a whole pizza each person gets
Llana [10]

Each person gets \frac{1}{8} of whole pizza

<em><u>Solution:</u></em>

Given that Mia has \frac{1}{2} of a pizza

She divides it equally among 4 people

<em><u>To find: Fraction of a whole pizza each person gets</u></em>

From statement,

\frac{1}{2} of pizza is divided equally among 4 people

Therefore, to find the fraction of whole pizza each person gets, we can divide the \frac{1}{2} by 4 people

\text{fraction each person gets } = \frac{\frac{1}{2}}{4}\\\\\text{fraction each person gets } = \frac{1}{2} \times \frac{1}{4}\\\\\text{fraction each person gets } = \frac{1}{8}

Thus each person gets \frac{1}{8} of whole pizza
