question 14 (1 point)
the force of gravity on an object varies directly with its mass. the constant of variation due to gravity is 32.2 feet p
which equation represents f, the force on an object due to gravity according to m, the object's mass?
a)
t = 16 17

13: Since f(1)=10, the sequence must start with 10. We have only one sequence starting with 10, and indeed it verifies f(n+1)=f(n)-2, i.e. the next term is 2 less than the previous one.

14: If y varies directly with x, then there is a constant of variation k such that

In your case, F varies directly with m, with a constant of variation of 32.2, so we have

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
