Two different types of alloy, a and b, have been used to manufacture experimental specimens of a small tension link to be used in a certain engineering application.

theultimate strength (ksi) of each specimen was determined, and the results are summarized inthe accompanying frequency distribution

ab[26,30)73[30,34)129[34,38)1519[38 ,42)710 total 4141

compute a 95% ci for the difference between the true proportions of all specimens of alloysa and b that have an ultimate strength of at least 34 ksi.

Jackie bought a bag of oranges. she used 3/8 of the oranges to make orange juice. she used 1/3 of the oranges to make a fruit salad. she put 1/8 of the oranges in a bowl on the table. she put 2/12 of the oranges in the refrigerator. a) jackie left more oranges on the table than she put in the refrigerator. b) jackie used fewer oranges to make orange juice than she left on the table. c) jackie put fewer oranges in the refrigerator than she used to make the fruit salad. eliminate d) jackie used more oranges to make a fruit salad than she used to make orange juice.

The square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
