Two groups of students, Group A and Group B, have the age distributions shown below. Which statement about the distributions is true? Distribution A

# of Students

M N O

15

19

16 17 18

Age

Distribution B

# of Students

15

16

17

18

19

Age

Distribution B has a larger mean, but the medians of both distributions are the same.

0

Distribution B has a smaller mean, but the medians of both distributions are the same

Distribution B has both a larger mean and a larger median than distribution A

Distribution B has both a smaller mean and a smaller median than distribution A

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

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

b
