Is 2 times the square root of 3 rational?

Hello from MrBillDoesMath!

Answer:

No

Discussion:

The square root of 3 is irrational so 2 * sqrt(3) is also irrational.

A dice game lets you roll 2 6 sided disc and find the sum of the numbers. A 12 wins 100 dollars, 10 or 11 wins 50 dollars, a 2 w

Advocard [28]

Answer:

Step-by-step explanation:

A two 6 sided die is rolled

Sample space would be (1,1)...(1,6)....(6,1)....(6,6)

Let x be the sum obtained

X can take values as 2 or 3 ....12

P(x=12) = P(6,6) =1/36

P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36

P(2) =P(1,1) = 1/36

For other outcomes no payment

Thus we can list this as

Sum 2 3 4 5 6 7 8 9 10 or 11 12

Prob 1/36 5/36 1/36

Gain 3 0 0 0 0 0 0 0 50 100

E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36

E(gain) = total= 353/36

Cost of game = 6

E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6

= 3.806

Ellie needs new grass in the circular pen for her chickens. There is 175.84 feet of fencing around the circular pen. What is the

pshichka [43]

<h3>Area of pen is 2462 square feet</h3>

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

Given that,

Ellie needs new grass in the circular pen for her chickens

There is 175.84 feet of fencing around the circular pen

Therefore,

Circumference = 175.84 feet

<h3><u>The circumference of circle is given as:</u></h3>

$C = 2 \pi r$

Where, "r" is the radius of circle

$175.84 = 2 \times 3.14 \times r\\\\175.84 = 6.28 \times r\\\\r = \frac{175.84}{6.28}\\\\r = 28$

<h3><u>The area of circle is given as:</u></h3>

$Area = \pi r^2\\\\Area = 3.14 \times 28^2\\\\Area = 3.14 \times 784\\\\Area = 2461.76 \approx 2462$

Thus area of pen is 2462 square feet
