Florian and michelle are trying to construct a triangle. florian says the side lengths could be 6, 8, and 10, and the angles of the triangle should have measures of 37°, 53°, and 90°. michelle says the side lengths could be 7, 7, and 14, and the angles should have measures of 35°, 65°, and 80°. which of the friends has the correct measurement for the triangle? how do you know? florian has the correct side lengths because they are all even numbers. florian has the correct side lengths because the measurements fit the triangle inequality rule. michelle has the correct side lengths because they are not all even numbers. michelle has the correct side lengths because their measurements fit the triangle inequality rule.

Are women's feet getting bigger? retailers in the last 20 years have had to increase their stock of larger sizes. wal-mart stores, inc., and payless shoesource, inc., have been aggressive in stocking larger sizes, and nordstrom's reports that its larger sizes typically sell out first. assuming equal variances, at α = .025, do these random shoe size samples of 12 randomly chosen women in each age group show that women's shoe sizes have increased? born in 1980: 8 7.5 8.5 8.5 8 7.5 9.5 7.5 8 8 8.5 9 born in 1960: 8.5 7.5 8 8 7.5 7.5 7.5 8 7 8 7 8 click here for the excel data file (a) choose the appropriate hypotheses assuming equal variances at α = .025.a. h0: μ1960 – μ1980 ≥ 0 vs. h1: μ1960 – μ1980 < 0. reject h0 if tcalc < –2.074.b. h0: μ1960 – μ1980 ≤ 0 vs. h1: μ1960 – μ1980 > 0. reject h0 if tcalc > –2.074.c. h0: μ1960 – μ1980 ≥0 vs. h1: μ1960 – μ1980 < 0. reject h0 if tcalc < 2.074.d. h0: μ1960 – μ1980 ≤0 vs. h1: μ1960 – μ1980 > 0. reject h0 if tcalc < 2.074. a b c d (b) the average shoe size of women has increased. false true

Kate had 50 tickets to use for rides at the fair. She lost some of them. Her dad doubled the tickets she had left. Kate wrote the expression 2(50−t) to find the number of tickets she has now, where t is the number of tickets she lost. Jack correctly wrote another expression, 100−2t , to find the number of tickets Kate has now. Use the drop-down menus to explain what each part of Kate's and Jack's expressions mean. Kate's Expression: 2(50−t)2:50: t: 50−t:Jack's Expression: 100−2t100:t:2t:100−2t: thats what I need answered
