Answer: Randomly assign the 1,200 students to <u>6 equal-sized</u> groups. Then select one of the groups and place their names in the bin. Randomly select the winner from the bin.
Step-by-step explanation:
First, let us see how many bins we will need in total.
1,200 students / 200 notecards per bin = 6 bins
Now, the first two options do not give all students a fair chance of winning. They are not our answer.
The last two have a different number of groups. Looking at the calculation we did earlier, we will need 6 equal-sized groups. This means our answer is the last option.
Answer:
1120 Eagles
Step-by-step explanation:
If the population of Eagles decreases by 4% percent each year, then in 2030 (which is 15 years later), the population would decrease by (4 × 15)%
that is 60%
This indicates that the population of bald eagles in the year 2030 would be 60% less of what it was in the year 2015.
so we have,
× 2800
which gives us 1680
this means that the number of bald eagles in the year 2030 would be 1680 less than the number of bald eagles in the year 2015
hence 2800 - 1680
then the answer is 1120 Bald Eagles
Answer:
True
Step-by-step explanation:
In this question, we are expected to evaluate the validity of a particular proposition.
To evaluate this validity, what we do is that we check if the calculations as projected on the question are correct.
Let’s proceed!
Number of dogs to cat ratio = 4:5
Number of animals is 270;
Number of dogs will be 4/9 * 270 = 120
Number of cats will be 5/9 * 270 = 150
Now let’s check if the number of dogs is 4/5 that of cats.
Obviously 4/5 * 150 = 120
This makes true, the statement
