Each section of a spinner is labeled with a unique number and is the same size and shape as the other sections. the spinner is spun two times. the number of possible outcomes is 16. how many sections is the spinner divided into?

4

Step-by-step explanation:

4 x 4 = 16

each section has 4 chances when combined

example

1 and 1

1 and 2

1 and 3

1 and 4

2 and 1 etc

The spinner is divided into 4 sections

Step-by-step explanation:

Each section of a spinner is labeled with a unique number and is the same size and shape as the other sections.

On spinning the spinner is two times,the number of possible outcomes is 16.

Let number of outcomes on spinning it once be n

Then, number of outcomes on spinning it twice will be n²

(since, if 1,2,3 are outcomes in one spin than outcomes in two spins are:

11   12  13  

21  22  23  

31  32  33)

n²=16  ⇒ n=4

Hence, spinner is divided into 4 sections

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
