1. an automotive part must be machined to close tolerances to be acceptable to customers. production specifications call for a maximum variance in the lengths of the parts of 0.00054. suppose the sample variance for 40 parts turns out to be s2 = 0.00069. use α=0.05 to test whether the population variance specification is being violated.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
