the table shows the results of four surveys that randomly sampled 50 families in a town about the number of pets their family has.

0 pets 1 pet 2 or more pets total
survey 1, 12 13 25 50
survey 2, 20 21 9 50
survey 3, 10 13 27 50
survey 4, 11 12 27 50
identify surveys that are likely biased. based on the unbiased surveys, what percent of the families in the town are expected to have 2 or more pets?

a: 40 %

b: 44 %

c: 53 %

d: 59 %

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

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
