A random sample of 20 students from both the Science and Math club were surveyed about what supplies they would like to purchase
for various projects. If there are 240 students in the Math club, how many students can you expect to choose calculators?

1 answer:
Answer:
<u>84 students </u>
Step-by-step explanation:
See the attached table
As shown there are 20 students from Math club, 7 of them would like to choose calculators.
so, the probability of students who choose calculators = 7/20
If there are 240 students in the Math club
So, the number of students expected to choose calculators = 240 * 7/20
<u>So, the number of students = 84 students </u>

For the given geometric sequence, we have:
So the correct option is B.
<h3>Which is the recursive formula?</h3>Here we have the geometric sequence:
To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:
Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.
Then the correct option is B.
