Consider the recursive formula an = (2 + an-1) / 2
wel

Answer: The correct option is B. The third term is 4.

Explanation:

The given recursive formula is,

a_n=\frac{2+a_{n-1}}{2}

It is given that the first term is 10. So,

a_1=10

To find third term, first we have to find the second term.

a_2=\frac{2+a_{2-1}}{2}

a_2=\frac{2+a_{1}}{2}

a_2=\frac{2+10}{2}

a_2=\frac{12}{2}

a_2=6

Therefore the second term is 6.

a_3=\frac{2+a_{3-1}}{2}

a_3=\frac{2+a_{2}}{2}

a_3=\frac{2+6}{2}

a_3=\frac{8}{2}

a_3=4

Therefore, the correct option is B. The third term is 4.

The ratio of the number of beads Karen had to the number of beads Patricia had was 2:5 .After Patricia bought another 75 beads,t
Andre45 [30]
We can bring the ratios to a similar form, because 2:5 is the same as 4:10 (we can mupltiply rations by the same number)

so one ratio is 4:10 and the other is 4:15 and the difference is is 75 beads

in this ratio, we can see each number corresponding to a "unit" of beads: that means that what changed is that Patricia now has 5 more such groups (15-10=5), and since she has 75 beads more each unit must be 75/5=15.

so afterwards (and before) Karen had 4 such units, that is 60, and Patricia before had 10 such units, that is 150.

Which option below demonstrates the correct interval notation for a
Vladimir [108]

The correct interval notation for the continuous set of all numbers between 5 and 6, including 5, but not including 6 is [5, 6) option (C) is correct.

<h3>What is interval notation?</h3>

It is defined as the representation of a set of values that satisfy a relation or a function. It can be represented as open brackets and close bracket the close the brackets means the value is at the close bracket also included, and open bracket means the value at the open bracket does not include.

We have:

Continuous set of all numbers between 5 and 6, including 5, but not including 6.

From the above statement we can represent the number in the interval notation:

The numbers are between 5 and 6.

(5, 6)

As it is mentioned that 5 is included and 6 is not included, then:

[5, 6)

Thus, the correct interval notation for the continuous set of all numbers between 5 and 6, including 5, but not including 6 is [5, 6) option (C) is correct.

PLS HELP WILL MARK BRAINLIEST
gavmur [86]

Answer:

1. Rolling a number less than 5

         The numbers on a standard dice are 1, 2, 3, 4, 5, and 6. Therefore it is possible to roll a 6, but it is much more likely to be 1-5, simply because there are more of them.

2. Rolling a 2

          Again, it is more likely that the result will be one of the other 5 numbers. But obviously a 2 is still an option, so it's not impossible.

3. Rolling a number less than 10

          Every option is less than 10 so it is certain.
