How would you answer this question?

Positive; P increases

Step-by-step explanation:

When gasoline prices go up, the demand for push lawn mowers increases, so the sign of the cross-elasticity is positive.

If gasoline prices go up, and demand for push lawn mowers goes up, then the price for push lawn mowers will also go up.

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
