There are 40 students in a class. Among them 15 are boys and remaining girls. Find the probability of selecting a girl. Hope u can help m!!!...

5/8 or 0.625

Step-by-step explanation:

number of students in class=40

Boys=15

Girls = 40-15

40-15=25

25/40=5/8 or 0.625

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
