⇒A Number is said to be Rational, if it can be written in the form of \frac{p}{q}, otherwise it is Irrational.

⇒Decimal expansion of Rational is either Terminating or Non Terminating Repeating.For example ,0.234, 0.222222........,

⇒Decimal expansion of Irrational is always "Non Terminating non repeating".For example ,√2,√3, 0.23023002300023.......,

A.\rightarrow 0.144-----\text{Rational}\\\\B.\rightarrow \sqrt{0.144}\\\\=\sqrt{\frac{144}{1000}}\\\\=\frac{1.2}{\sqrt{10}}-----\text{Irrational}

⇒∵ ,√10, is Irrational.

C.\rightarrow \sqrt{0.0144}\\\\=\sqrt{\frac{144}{10000}}\\\\=\frac{12}{100}\\\\=0.12-----\text{Rational}

The sums that appear when two fair? four-sided dice? (tetrahedrons) with sides 1?, 2?, 3?, and 4 are tossed
Karolina [17]

Answer:

The possible sums are 2, 3, 4, 5, 6, 7 & 8 (but they're not all equally likely)

Step-by-step explanation:

For example, the only way to get a sum of 2 is to roll a 1 and then a 1

And the only way to get a sum of 8 is to roll a 4 and then a 4 (imagine you don't roll the two dice simultaneously; this will help you to see the "other possibilities" that aren't obvious at first)

The probability of rolling a sum of 2 = probability of rolling sum of 8 (1/16 probability for each)

If you roll a 1 then a 2, or a 2 then a 1, there are 2 ways to get a sum of 3

If you roll a 3 then a 1, a 2 then a 2, or a 1 then a 3, there are 3 ways to get a sum of 4

If you roll a 4 then a 1, a 3 then a 2, a 2 then a 3, or a 1 then a 4, there are 4 ways to get a sum of 5 (5 is the most likely sum)

If you roll a 4 then a 2, a 3 then a 3, or a 2 then a 4, there are 3 ways to get a sum of 6

If you roll a 4 then a 3, or a 3 then a 4, there are 2 ways to get a sum of 7

Pls HELP I BEG YOUUUU
Stells [14]

Answer:

x = 60

Step-by-step explanation:

(x+22) + (x+6) + (x-28) = 180

x + 22 + x + 6 + x - 28 = 180

x + x + x + 22 + 6 - 28 = 180

3x = 180

x = 180/3

x = 60
