50 + 5/13 p is equal to what number when p= -26

Answer

-60

Explanation

We can solve this by substituting p with -26 in the equation.

-50 + 5/13 p

When p =-26

-50 + 5/13 p = -50 + (5× -26)/13

                     = -50 + (5×-2)

                     = -50 + -10

                     = - 60

tangent

step-by-step explanation:

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
