1. A school principal needs to pick a student at random to appear in a commercial. In order to be fair, she decides to put the names of students on pieces of paper and pick one at random from a hat. She puts the names of 100 5th grade, 100 6th grade, 100 7th grade, and 100 8th grade students in the hat. I a) Create a probability model showing the theoretical probabilities of a student from each grade being chosen:

b) Does this show a uniform probability model? Explain.​

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

(-1,-0.5)

step-by-step explanation:

false

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
