A survey was conducted on a random sample of students at a college campus to study student opinions on the new honors program. Out of the students surveyed, 78% rated the new honors program as "very rigorous" with a margin of error of ±3% and a confidence interval of 90%.

What does the margin of error imply?
A.
It can be concluded, with 90% confidence, that at least 75% of all students will rate the new honors program as "very rigorous."
B.
It can be concluded, with 78% confidence, that at least 87% of all students will rate the new honors program as "very rigorous."
C.
It can be concluded, with 78% confidence, that between 87% and 93% of all students will rate the new honors program as "very rigorous."
D.
It can be concluded, with 90% confidence, that between 75% and 81% of all students will rate the new honors program as "very rigorous."

What is the domain and range of each function 1. x (3, 5, 7, 8, 11) y ( 6, 7, 7, 9, 14) 2. x (-3, -1, 2, 5, 7) y (9, 5, 4, -5, -7)

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
