BRAINLIEST - Max is stacking logs at his campground for firewood. After his first load of logs, he has 9 logs on the stack. After his seventh load of logs, he has 51 logs on the stack. Use sequence notation to represent the arithmetic function.
A. an = 51 + 6(n − 1)
B. an = 9 + 6(n − 1)
C. an = 51 + 7(n − 1)
D. an = 9 + 7(n− 1)

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
