the function f(x) = 2x + 510 represents the number of calories burned when exercising, where x is the number of hours spent exercising.
the function g(x) = 200x − 125 represents the calorie deficit that occurs when combining diet with exercise, where x is the number of hours spent exercising.
what is (f + g)(1)? explain.
512 calories burned while exercising for 1 hour
587 calories burned while exercising for 1 hour
512 calories burned while combining diet with 1 hour of exercise
587 calories burned while combining diet with 1 hour of exercise

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the correct answer is the second option

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
