Algebra (lots of points but put work and effort in ): a group of students were surveyed to find out if they like watching television or reading during their free time. the results of the survey are shown below: 90 students like watching television 20 students like watching television but do not like reading 80 students like reading 40 students do not like watching television make a two-way table to represent the data and use the table to answer the following questions. part a: what percentage of the total students surveyed like both watching television and reading? show your work. part b: what is the probability that a student who does not like watching television also does not like reading? lots of info, but do not be stupid. you

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

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
