A new device has been developed that has two electrical circuits that work in parallel and two memory chips. The second chip backs up the first. Whether the individual chips or electrical circuits fail are independent. RequireD:
a. The probability that a circuit fails is 0.15, and the probability that a memory chip fails is 0.07. The device fails, and the engineer testing it determines that both circuits have burned out. What is the probability that would occur?
b. The engineer determines that using only two circuits leaves too much to chance and decides to use three. He also does a quality upgrade that lowers the probability of circuit failure to 0.04. What is the probability that all 3 upgraded circuits fail?
c. The engineer runs a final quality check, putting the device through as many extreme situations as he can. What is the probability that 3 upgraded circuits fail and 3 memory chips fail? (Round your answer to eight decimal places.)

The minimum wage in washington has been increasing over the last ten years. years 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 washington state minimum wage $6.50 $6.72 $6.90 $7.01 $7.16 $7.35 $7.63 $7.93 $8.07 $8.55 $8.55 a) find the linear regression equation for the minimum wage in washington using this data ( x  0 in 2000). round to the thousandths. b) what is the slope? specifically, what does the slope represent in the real world context? c) what is the y-intercept? specifically, what does the y-intercept represent in the real world context? d) write your equation as a function of x. e) if you do not earn a college degree and you are earning minimum wage in 2020, what do you predict you will be earning per hour with the linear regression equation? f) if the trend continues, when will the minimum wage be $15 an hour? 3. why are your answers to #1d and #2a above different? which do you think is more accurate (#1 or #2) and why
