A number cube is rolled three times. What is the probability of rolling three even numbers?

1 answer:

6 0

It depends on how many numbers are on the cube. If the cube goes up to five then you have a 2/5 chance to roll an even number one time. If the dice goes up to 10 then you have 5/10 chance of rolling an even number.

$\begin{array}{ccc}10\ lb&-&\$6.55\\\\1\ lb&-&\$ x\end{array}\ \ \ |cross\ multiply\\\\\\\\10\cdot x=1\cdot6.55\\\\10x=6.55\ \ \ \ |divide\ both\ sides\ by\ 10\\\\x=\frac{6.55}{10}\\\\x=0.65\underline{5}\approx\boxed{\$0.66}\\$

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

Claire earns $8.50 per hour babysitting plus a $15 travel fee. Brooklyn earns $9.50 per hour walking dogs plus a $5 supply fee.

ANTONII [103]

Answer:

I believe Claire makes $24.50 and Brooklyn makes $14.50, so if you wanted to make Brooklyn walk an extra hour, she would have 24.00 adding the supply fee which is $5 which would make it $29.00.

Now i am going to try to actually solve it

8.50x15=127.5

9.50x5=47.5

9.50x13=123.5
