A class quiz has 4 multiple-choice questions and each question has 4 possible answers (A, B, C, or D). The correct answers are B, C, A, and A, in that order, and you must correctly answer at least three questions to pass the quiz. Use the drop-down menus to design the best possible scenario to find the experimental probability of passing the quiz by guessing. Which simulation tool would you use? How many results do you need for each trial? What is the theoretical probability that you would guess the correct answer to every question?

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

so, converting firstly the mixed fractions to improper fractions and then "adding".
