True or false? pls halp asap! : o

in this picture, the measure of angle theta is 1 radian.

False

Step-by-step explanation:

Radius of circle = r = 2.5 in

Length of arc of the circle = s = 2 in

Central angle in radians = θ

The length of arc of the circle is the product of the radius and the central angle in radians.

s = rθ

θ = 0.8 radians

The measure of angle θ is not 1 radian but 0.8 radian.

False

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
