4. Data are collected on the amount of fat (in grams) and calories in the fronch
fry orders at nine fast food restaurants. The least-squares regression line for the
data is ý = 274.34 + 9.552, where y is the predicted number of calories and z
is grams of fat. Which of the following is the correct interpretation of the slope
of the least-squares regression line?
(A) The calories increase by 9.55, on average,
(B) For every increase in fat, the calories increase as well
(C) Every increase of 1 gram of fat causes an increase of 9.55 calories,
(D) For every increase of 1 gram of fat, the predicted calories increase by 9.55,
f) For every increase of 1 calorie, the predicted grams of fat increase by 9.55.

If the value of cos330°is√3/2 then find cos 165°.

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)
