Answer: No

Step-by-step explanation:

Rachael getting a head every time she tosses a coin ten times is unlikely.

Theoretically, there will be some head and tails during the toss of the coin. Theoretically, there should be 5 heads after ten tosses of the coin.

To get exactly 10 heads during the tosses of coin, Rachel would need a larger trial to get a more accurate data.

Find the next three sequence of 1,3, 9, 27,

Andreyy89

Answer: 81, 243, 729

Step-by-step explanation:

STEP ONE: Find a pattern in the sequence

3 ÷ 1 = 3

9 ÷ 3 = 3

27 ÷ 9 = 3

As we can see from the given sequence, each number multiplies 3 to get the next term.

STEP TWO: Find the next three terms

27 × 3 = 81

81 × 3 = 243

243 × 3 = 729

Hope this helps!! :)

When working with the square root of a number, when would you have only a positive answer and when would you have both a positiv

Rama09 [41]

Lets make it clear: You would have a positive answer when the value you are looking for has to be a positive number. On the other hand you would have a positive and a negative answer when you take the square root of something that doesn't have to be positive. it could be either because when a negative number is squared it becomes positive and when a positive number is squared it stays positive as well.
