Answer:

YES IT IS

Step-by-step explanation:

2-3 + 3.3

= -1 + 3.3

= -4.3

We learn that:

Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.

In this case, -4.3 can be write as -43/10

So YES it would be a rational number

Hope this helped :3

Is 9.521521521 rational or irrational

enyata [817]

If the numbers after the decimal terminate, yes, it's rational.

9.521521521 = 9,521,521,521 / 1,000,000,000

If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.

If x = 9.521521521…, then

1000x = 9521.521521521…

Subtract x from this to eliminate the fractional part:

1000x - x = 9521.521521521… - 9.521521521…

999x = 9512

x = 9512/999

If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like

9.52152152119484929271283583457…

then the number would be irrational.

According to the general equation for conditional probability, if P(A^B)= 2/3 and P(B)= 3/4, what is P(A|B)? A. 15/16 B. 24/25 C

Evgen [1.6K]

Ell it could be any of these to be perfectly honest but none of these are the answer I believe because none of them give you a 3/4 proportion. So it could be none of the above if thats an answer.

two angles are conplementary angles. One angle measures 59 the other measures (4n-1) what is the value of n

natulia [17]

Answer:

n = 8

Step-by-step explanation:

Complementary angles add up to 90°

So,

59° + (4n - 1) = 90°

4n - 1 = 90° - 59° = 31°

4n = 31° + 1° = 32°

4n° = 32°

n = 32 ÷ 4 = 8
