Answer:

C. 35 square centimeters

Step-by-step explanation:

What we need for this question:

The edges of a cube are 5 centimeters each.

The face diagonal is about 7 centimeters. (actually 7.0710678118655 cm)

To find the cross sectional area here, multiply 5 cm by 7 cm.

5 cm * 7 cm

35 cm² is your final answer, so C is the answer.

Greeley [361]

Answer:

P(A \cap B) = P(A) *P(B) =\frac{1}{5} \frac{1}{5}= \frac{1}{25}

So then the best option would be:

a. 1/25

Step-by-step explanation:

For this case we assume that the sample space for the numbers is :

S_1= [A,B,C,D,E]

And the sample space for the numbers is:

S_2 =[1,2,3,4,5]

Both sampling spaces with a size of 5.

We define the following events:

A="We select a 2 from the numbers"

B= "We select a E from the letters"

We can find the individual probabilities for each event like this:

P(A)= \frac{1}{5}

P(B) = \frac{1}{5}

And assuming independence we can find the probability required like this:

P(A \cap B) = P(A) *P(B) =\frac{1}{5} \frac{1}{5}= \frac{1}{25}

The last probability is the probability of obtain obtain a 2 AND an E

So then the best option would be:

a. 1/25
