Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance. They have had three local matches, a, b and c, and will attend a district match. District match points count for twice the number of points than local matches do. Choose the equation that would help Tisha find how many points they need to earn in the district match, d, to advance. A:d equals T minus a minus b minus c all over 2
B:d equals T over 2 minus a minus b minus c
C:d equals T plus a plus b plus c all over 2
D: d = 2(T − a − b − c)

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.
