Answer:
Step-by-step explanation:
This can be solved with a very basic knowledge of probability and proportions. If we have 2 chances out of 7 to pick a blue marble, then we have 5 chances out of 7 to pick a red one, right? We can use that and set up a proportion with red marbles on top and total number of marbles on the bottom:
5/7 is the reduced fraction that represents the number of red marbles over the total number of marbles. Solving this way allows us to find out what the fraction was before it was reduced, hence, giving us the total number of red marbles. Cross multiply to solve:
7x = 420 so
x = 60. 60 red marbles total
The answer is 21 students volunteered and 14 stayed back
Since 1 and 2 are used at least once in half of the apartments, and no other number is used this often, either 1 or 2 will be the most frequent digit used.
<span>Since all of the numbers of the form </span><span> appear but only 6 of the numbers </span><span> appear, 2 will be used less often than 1 and we should count the number of 1s to find the number of packages needed.</span>
100 through 125 requires 26 ones just for the hundreds place. 100 through 125 and 200 through 225 require the same number of ones for the tens and units places; that is, thirteen.
<span>So, there are </span><span> ones used. Therefore, the landlord must purchase </span><span> 52 packages.</span>
