Answer:
E. 18 children are buying their lunches
F. Rock must pay $50 each month
Step-by-step explanation:
E.
To find a percentage you multiply the number by the percentage;
60 x 70%(0.70) = 42 children brought their lunches
But we need the amount <u>buying</u> their lunches so we would subtract 60 by 42;
60 - 42 = 18 buying their lunches
F.
Again, to find the percentage we multiply it by the original;
$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa
Now we need to find how much Rock still needs to pay for the sofa;
$800 - $200 = $600 more needed to pay for the sofa
Lastly, we must find how much Rock will need to pay <u>each month</u> to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;
$600 / 12 = $50 needs to be paid each month for a year
5+(-4)+12.65=
5-4+12.65=
1+12.65=
13.65 is the answer
<h3>
Answer: 0.29</h3>
Explanation:
We ignore the first row, and focus on the second row only, because we're told that they did not stay at the beachfront resort.
We have 0.05 of the entire sample visit St Lucia in the second row out of 0.17 total for that row. This leads to 0.05/0.17 = 0.29 approximately. There's roughly a 29% chance of someone visiting St Lucia given they stayed in a condo.
If you wanted, you can move the decimal point 2 spots to the right for every value in the table. That would mean of the 17 people who stayed in a condo, 5 of them visited St Lucia. So 5/17 = 0.29
