The sample of seven cars, each car was tested for nitrogen=oxide emissions (in grams per mile) and the following results were obtained: 0.09; 0.07; 0.19; 0.05; 0.08; 0.16 assuming that this sample is representative of the cars in use construct a 98% confidence interval estimate of the mean amount of nitrogen oxide emissions for all cars if the epa requries that nitrogen oxide emiisions be less than 0.165/mi can we safely conclude that this requirement is being metwhat is the confidence interval estimate of the mean amount of nitrogen oxide emissions for all cars __g/mi< \mu< /mi (round three decimal places as needed)\can we safely conclude that the requirement that nitrogen-oxide emissions be less than 0.165 is being meta) no because the confidence interval does not contain 0.165g/mib) no it is possible that the requirement is being met, but it is also very possible that the mean is not less than 0.165 g/mic) yes we can definently conclude that the requirement is met for all carsd) yes because the confidence interval contains 0.165 g/mi

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)
