Answer:

The probability of rolling an even number would be \frac{1}{2} or 50%.

Step-by-step explanation:

A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be \frac{3}{6}, which simplifies to \frac{1}{2} or 50%.

borishaifa [10]

Answer:

The number of laps for which two swimmers have raised the same amount of money is 6 .

Step-by-step explanation:

Given as :

The amount raised by Hailey = $27 + $1.50 × each lap she swim

The amount raised by Tariana = $18 + $3 × each lap she swim

Let The number of laps after which both swimmer raised same amount = n

Now, According to question

<u>For both swimmer to raised same amount</u>

I.e The amount raised by Hailey = The amount raised by Tariana

Or, $27 + $1.50 × each lap she swim = $18 + $3 × each lap she swim

Or,  $27 + $1.50 × n = $18 + $3 × n

Or, $27 - $18 = $3 n - $1.50 n

Or, 9 = 1.5 n

∴  n = \dfrac{9}{1.5}

I.e n = 6

So, number of lap for same amount of both = n = 6

Hence The number of laps for which two swimmers have raised the same amount of money is 6 . Answer
