Given that a = 6.1 m and b = 2.9 m, work out x.

Give your answer rounded to 1 DP.

x = 6.75426

Step-by-step explanation:

c = √a2 + b2

= √6.12 + 2.92

= √45.62

= 6.75426

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
