Tomatoes agricultural scientists are working on developing
an improved variety of roma tomatoes. marketing research
indicates that customers are likely to bypass romas that weigh
less than 70 grams. the current variety of roma plants pro-
duces fruit that averages 74 grams, but 11% of the tomatoes
are too small. it is reasonable to assume that a normal model
applies.

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Plz hurry evaluate the expression a+b where a=8 and b=19
