There is a group of kids who 64% of them have blue cars /!and another group with 1.8% red cars group A doesn’t have red car and group B doesn’t have blue cars. The rest have different color. 1- what is the probability of selecting a kid who has red car?
2- let’s say you pick a kid randomly what’s the probability of one them having a red car and the other blue?
3- what the probability of selecting one that has blue or red car at home?
4- let’s say you randomly selected 8 students what’s the probability of one of them having a blue car at home?

has red car?

2- let’s say you pick a kid randomly what’s the probability of one them having a red car and the other blue?

3- what the probability of selecting one that has blue or red car at home?

4- let’s say you randomly selected 8 students what’s the probability of one of them having a blue car at home?

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
