Hurry? ?

damien is trying to see if there is a relationship between owning a pet and sharing a room with a sibling. he interviewed his classmates and displayed his results in the two-way table shown. which statement is true?

a) more than half of his classmates have a dog.
b) it is more likely for a classmate who owns pet to share a room.
c) more than 10% of his classmates do not own a pet and don't share a room.
d) it is less likely for one of his classmates to have a cat and share a room than have a dog and not share a room.

my answer is b

B

Step-by-step explanation:

Calculate the relative frequency of each possibility:

Have a cat and share a room: 0.182

Have a cat and don't share a room: 0.121

Have a dog and share a room: 0.303

Have a dog and don't share a room: 0.152

Don't have a dog or cat and share a room: 0.152

Don't have a dog or cat and don't share a room: 0.090

The only choice that is correct is It is more likely for a classmate who owns pet to share a room.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
