The probability of getting a 2 and 3 in two cubes is \frac{1}{36}

<u><em>Explanation</em></u>

Total face values in each number cube is  6.

In first cube, probability of  getting a 2 is = \frac{1}{6}

and also in the second cube, probability of getting a 3 is = \frac{1}{6}  

So, the probability of getting a 2 and 3 in two cubes = \frac{1}{6}*\frac{1}{6}= \frac{1}{36}

The two numbers are (7+ sqrt(65))/2 and (7- sqrt(65))/2

(7+ sqrt(65))/2+ (7- sqrt(65))/2= 7
(7+ sqrt(65))/2* (7- sqrt(65))/2)= -4.

In April, the Messa family gets 800 text messages included in their plan. Together, Tommy and Mary use half of the messages. Jac
laiz [17]

Answer: See explanation

Step-by-step explanation:

Total number of text messages = 800

Amount used by Tommy and Mary = 1/2 × 800 = 400

Number of messages uses by Jack and Stefanie = 240

The expression to find the number of messages Cathy uses will be:

= 800 - (1/2 × 800) - 240

Since the expression is 800 - (1/2 × 800) - 240, the number of messages that Cathy will use will be:

= 800 - (1/2 × 800) - 240

= 800 - 400 - 240

= 160 messages
