Solve 1.25x + 1.50y = 28.25.

Step-by-step explanation:

Assuming you are solving for the intercepts.

for x you set y to 0.

28.25 = 1.25x

divide by 1.25 on both sides.

you get 22.6

for y you set x to 0

28.25 = 1.5y

divide by 1.5

you get 18.83 repeating

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

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
