The flow rate y (m3/min) in a device used for air-quality measurement depends on the pressure drop x (inchof water) across the device’s filter. Suppose that for x values between 5and 20, the two variables are related according to the simple linear regression model with true regression line y = −.12 + .095x. a. What is the expected change in flow rate associated with a 1-in. increase in pressure drop? Explain. (3 marks)b. What change in flow rate can be expected when pressure drop decreases by 5 in.? (1 mark)c. What is the expected flow rate for a pressure drop of 10 in.? A drop of 15 in.? (2 marks)d. Suppose 휎=.025 and consider a pressure drop of 10 in. What is the probability that the observed value of flow rate will exceed .835? That observed flow rate will exceed .840? (4 marks)e. What is the probability that an observation on flow rate when pressure drop is 10 in. will exceed an observation on flow rate made when pressure drop is 11 in.?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

yes

step-by-step explanation:

yes
