I'LL GIVE BRAINLIEST Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.

Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.

Translate Sarah's expression into a verbal expression. Use words such as sum, product, etc. (6 points)

Use either the commutative property or combine like terms to create an equivalent expression of Sarah's expression. (6 points)

Use the distributive property to create an equivalent expression. (6 points)

Pick a number from 1 to 10. Use that number to verify that all 3 expressions are equivalent (the original, the one from #1, and the one from #2) by substituting it into each expression. Show all your work for complete credit. (6 points)

Look at the number you picked in the previous question. This number represents the amount of teeth John found. How many teeth did Sarah find? (Hint: Sarah found twice as many as John plus the 3 teeth she found before John started helping. (6 points)

Aprisoner is trapped in a cell containing three doors. the first door leads to a tunnel that returns him to his cell after two days of travel. the second leads to a tunnel that returns him to his cell after three days of travel. the third door leads immediately to freedom. (a) assuming that the prisoner will always select doors 1, 2 and 3 with probabili- ties 0.5,0.3,0.2 (respectively), what is the expected number of days until he reaches freedom? (b) assuming that the prisoner is always equally likely to choose among those doors that he has not used, what is the expected number of days until he reaches freedom? (in this version, if the prisoner initially tries door 1, for example, then when he returns to the cell, he will now select only from doors 2 and 3.) (c) for parts (a) and (b), find the variance of the number of days until the prisoner reaches freedom. hint for part (b): define ni to be the number of additional days the prisoner spends after initially choosing door i and returning to his cell.
