bob has 3/4 cup of flour. he needs 1/8 of a cup of flour to make a biscuit. How many biscuits can bob make? show how many eighths are in 3/4 by using number lines. Divide one whole into fourths on one number line. Under that show another number line divided into equivalent eighths. show that 3/4 divided 1/8 is the same as 3/4 the reciprocal of 1/8 (8/1 or just 8).​

The investigating team suspected that there were differences in the cost of repairing cars in workshop i and workshop ii. the investigating team suspected that the costs raised by workshop i were greater than workshop ii. for that they tested the repair of 15 cars in each workshop to see the cost of repairs.the decision of the right hypothesis to prove the suspicion above is a. h0 : μ1- μ2­ = 0; ha : μ1- μ2­ ≠ 0 b. h0 : μ1- μ2 ≥ 0; ha : μ1- μ2 < 0 c. h0 : μd ≥ 0; ha : μd < 0 with μd = μ2- μ1 d. h0 : μd = 0; ha : μd ≠ 0 with μd = μ2- μ1 e. h0 : μ1- μ2 = 0; ha : μ1- μ2 ≥ 0
