25% chance

Based on the results, I concluded that for Heads, Heads (which could be dogs or cats) there was a 24% chance and for Tails, Tails there was a 26% chance

<span>4. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?

1/8 chance (accidentally messed up there) or 12.5%

Which statement describes the relationships between x and y in these two equations?
Maru [420]
B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.

Out of all the answer choices, b makes the most sense.

25x can be translated as 25 times x.

x + 25 can be translated as 25 more than a number.



Hope this helps!
