It is important that face masks used by firefighters be able to withstand high temperatures because firefighters commonly work in temperatures of 200-500°f. in a test of one type of mask, 12 of 60 masks had lenses pop out at 250°. construct a 90% upper confidence limit for the true proportion of masks of this type whose lenses would pop out at 250°. (round your answers to four decimal places.)

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

When y’all answer can y’all explain too !

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
