Let the sample size of the television tube brightness experiment be ten and the sample mean and sample standard deviation be 268.0 microamps and 16.4 microamps, respectively. Suppose that the design engineer claims that this tube will require at least 250 microamps of current to produce the desired brightness level.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
