Answer:

1st, third, fifth

Step-by-step explanation:

sqrt(3) is irrational, so dividing it by 2 won't do anything

1/3 is rational

54 is not a perfect cube, so it's irrational

27^{1/3} = cbrt(27)=3, rational

sqrt(0.25)=0.5. 0.5*0.5=0.25. rational

pi is irrational(3.1415926535897932384626433832...)

Answer:

1, 3, and 5 are irrational.

Step-by-step explanation:

\frac{\sqrt{3} }{2} is irrational because the square root of 3 is irrational, and if you divide it by 2, it will still be irrational!

2 is rational: the definition of a rational number is a number that can be expressed in the form a/b, where b is nonzero.

3 is not rational: 54 is not a perfect cube, therefore, its cube root will not be rational.

4 is rational. The square root of 0.25 is 0.5, which can be expressed in the form a/b, b is nonzero. 0.5 = 1/2!

5 is irrational. Pi is a famous irrational number, because it goes on forever without a pattern!

Hope this helps :) If you have any questions or concerns please feel free to reach out to me!

=60°

ext \: ang =  \frac{360}{n}

n=360°/60°

n=6

second polygon

n=2(6)=12

ext. ang= 360°/n = 360°/12° = 30°

int. ang = 180°-30°= 150°

The proportion of the total area under a normal curve between two z-scores corresponds to the ______ of that range of scores.
omeli [17]

Answer:

For any normal distribution, the mean and the median will have the same value. For any normal distribution, the proportion corresponding to scores greater than z = +1.00 is exactly equal to the proportion corresponding to scores less than z = -1.00.

Any help please? Having a hard time
german

Answer:

the answer is c

Step-by-step explanation:

x and y have to be at least 12, so that's why the greater than sign was used

the amount of money had to be at most $230, so that's why the less than sign was used

they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y
