Two tails on two coins, 1/4 chance
An even number on a die 3/6 or if simplified, 1/2.

The other answer is correct if these are separate tasks.  However, if you need to flip two tails and roll an even as the question states you need to multiply the probabilities together.
It is 1/2 to flip a tail and we have that twice and 1/2 to roll an even and we have that once so the formula is

1/2 * 1/2* 1/2 = 1/8

The probability of doing all three things together is 1/8

If you write all the whole numbers from 1 to 500 in a row, what will be the 500th digit?
Hitman42 [59]

Answer:

Option A.

Step-by-step explanation:

We need to find the 500th digit if we write all the whole numbers from 1 to 500 in a row.

Single digit numbers are : 1-9 = 9 number = 9 digits

Double digit numbers are : 10-99 = 90 number = 180 digits

Total digits form 1 to 99 = 9+180 = 189

Now,

500-189=311

It means we have write 311 more digits.

After 99 we have 3 digit number.

311 is not divisible by 3. The number immediate before 311 which is divisible by 3 is 309.

\frac{309}{2}=103

It means the required digit is 2nd digit of 104th number after 99.

104th number after 99 is 203 and second digit of 203 is 0.

Therefore, the correct option is A.

What is the expression in simplest radical form?<br><img src="https://tex.z-dn.net/?f=%285x%5E%7B4%7D%20y%5E%7B3%7D%29%5E%7B%5Cf
Vlad [161]

Use the formula a^(x/n) = (n)√a^x   (note it is a small n)

(5x^4y^3)^(2/9) = Small 9

Convert.

\sqrt{9{{(25x^{8})y^9 }}} is your answer

hope this helps

What’s the measure of the missing angles?
Ymorist [56]

Answer:

Angle 1 equals 90 degrees. Angle 2 equals 38 degrees.

Step-by-step explanation:

Angle 1 is at the cross of two perpendicular lines, making it 90 degrees. Angle 2 can be found by making the two equal side lengths and the middle line into one triangle. This means that two of the angles are 52 degrees. This leaves 76 degrees to be split in the triangle. The middle line cuts the angle in half, making it 38 degrees
