I'll give the brainliest to the first right answer! Alexis counted 10 red cards and 20 black cards in a deck of cards. What is the ratio of red cards to black cards?

a) 1:1 b) 1:2 c) 1:2 d) 2:2

It is c. that is because there are 10 red to 20 black which is a 10:20 ratio. you can simplify this to 1:2 since they are both divisible by 10

The shaping always moves forward. even if the progress breaks down you have to take a step back before moving forward again but there is no such thing as backward shaping

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
