Suppose that we have collected a random sample of 49 breakfast orders from a major hotel chain, noting for each order how long the guest had to wait for the order to arrive once the order was placed. We find that, on average, guests had to wait 9.5 minutes for their breakfast order to be delivered. Additionally, it is known that the population standard deviation for the wait time of a breakfast order is 1.5 minutes. Use the information above to construct a 95% confidence interval for the population mean wait time of a breakfast order (in minutes). Once you have constructed such an interval, choose the values below that best correspond to your confidence interval. Note: Our experimental unit here is breakfast orders, not hotel guests. a) (-9.92,-9.08)
b) (1.12, 1.88)
c) (9.08, 9.92)
d) (9.44, 9.56)
e) (-1.16, 4.16)

Find the equation of a line whose slope is 2/5 and y- intercept is 2.write your answer in the form 1) ax+by+c=02) x/a+y/b=1

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)
