A bag has 4 Hershey's bars, 5 Twix, 7 Reese's bars, and 9 Milky Way bars.
Caroline randomly picks a piece of Cândy from the bag, puts it back, and then pícks out another one. What is the
probability that Caroline does NOT pick a Hershey's bar and then does NOT pick a Twix?
#Hint: 4 + 5 + 7 + 9 = 25 total
P(NOT Hershey's and then NOT TWix) = _
b
4/25 - 5/25 = 20/625 = 4/125
4/25 * 5/24 - 20/600 - 1/30
21/25 * 20/25 - 420/625 - 84/125
21/25 * 20/24 = 420/600 - 7/10

5× 1/2 = ? a) more than 5 because you are multiplying by a whole number b) 5/10 because you multiply the numerator and denominator by 5 c) less than 5 because you are multiplying by a number that is more than 1 d) less than 5 because you are multiplying by a number that is less than 1

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
