3. This spinner is divided into eight equal-sized sections. Each section is labeled with a number
givi [52]

Answer:

Least Likely: Arrow lands on a section labeled with an odd number.

_____: Arrow lands on a section labeled with the number 1.

Most Likely: Arrow lands on a section labeled with a number less than 4.

Step-by-step explanation:

<u>The spinner:</u>

There are 8 sections, 4 labeled with the number 1, 2 labeled with the number 3, 1 labeled with the number 3, and 1 labeled with the number 4.

<u>Probabilities of the spinner:</u>

  • Probability of landing on 1: 4/8 - 50%
  • Probability of landing on 2: 1/8 - 12.5%
  • Probability of landing on 3: 2/8 - 25%
  • Probability of landing on 4: 1/8 - 12.5%

<u>The options:</u>

A - Arrow lands on a section labeled with an odd number.

B - Arrow lands on a section labeled with the number 1.

C - Arrow lands on a section labeled with a number less than 4.

  1. The least likely possibility out of the options would be B because, while a 50% chance sounds like a lot, it is the least of the three options.
  2. The mid possibility out of the options would be A. The odd numbers labeled on the spinner make up 75% of the whole. (1s and 3s - 50% + 25%)
  3. The most likely possibility out of the options is C because it accounts for every section except for the single section labeled with the number 4. (100% - 12.5%, 87.5%)

PLEASE HELP ME WITH THIS ALGEBRA QUESTION!! THANK YOU!!
lesantik [10]

Answer:

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Given recursive formula is:

a_n = 3a_{n-1}+7

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

a_2 = 3a_{2-1}+7\\a_2 = 3a_1+7\\a_2 = 3(-10)+7\\a_2 = -30+7\\a_2 = -23

Putting n=3

a_3 = 3a_{3-1}+7\\a_3 = 3a_2+7\\a_3 = 3(-23)+7\\a_3 = -69+7\\a_3 = -62

Putting n=4

a_4 = 3a_{4-1}+7\\a_4 = 3a_3+7\\a_4 = 3(-62)+7\\a_4 = -186+7\\a_4 = -179

Hence,

The first four terms of the sequence are: {-10,-23,-62,-179}
