Question 1: f(x)=x^5
Solve f`(x)

Question 2:
f(x)=4 * x^7
Solve f`(x)

Question 3:
f(x)=x^8,5 + 3
Solve f`(x)

Question 4:
p(x)=x^3 - x^5
Solve p`(x)

Question 5:
f(x)=3 * x^-4
Solve f`(x)

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
