A clothing company sells hats online to its customers. The price of each hat is p dollars. The shipping cost is s dollars. The equation shown below can be used
to find the total cost (c), in dollars, when n hats are purchased. c np s = +
Which equation can be used to find the price of each hat when 5 hats are
purchased, the shipping cost is $6, and the total cost is $41?
1) c = 5 (6)+41 2) c = 6 (41)+5 3) 41 = 5p+6 4) 41 = 6p+5

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
