Apart of a line consisting of two endpoints and all points between them

i got 10.28 but that rounds up to 10.3

answer: certain

step-by-step explanation:

the probability of any event is a number which tells the chances that the event will happen or not .

an event that is certain to happen has a probability of 1.

an event that is uncertain to happen has a probability of 0.

therefore, if the the probability of choosing an apple-flavored juice box out of the refrigerator without looking is 1 .

question says to graph a triangle (xyz) and reflect it over the line y=x to create triangle x'y'z'.

we know that line y=x has both coordinates equal like (1,1), (5,5) etc so we can easily graph that reflecting line.

description of transformation:

we can see that x and y coordinate gets switched after transformation like (2,8) changed to (8,2)

what do you notice about the two line segments you drew:

we see that line segments xp and x'p are of same length and perpendicular to the reflecting line y=x.

do you think you would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line? :

yes, i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line.

how do you know? :

by measuring the length of yk and y'k.
