Alumber company is making boards that are 2533.0 millimeters tall. if the boards are too long they must be trimmed, and if the boards are too short they cannot be used. a sample of 14 is made, and it is found that they have a mean of 2536.4 millimeters with a variance of 64.00. a level of significance of 0.05 will be used to determine if the boards are either too long or too short. assume the population distribution is approximately normal. is there sufficient evidence to support the claim that the boards are either too long or too short?

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

Need on this geometry question. explain how you did it.

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.
