Answer:
A.)
Lower Value = 295
Upper Value = 485
B.)
Lower Value = 200
Upper Value = 580
C.)
Lower Value = 105
Upper Value = 675
Step-by-step explanation:
Given that mean (M) = 390
Standard deviation (σ) = 95
Lower Value = mean value - number of standard deviations specified
Upper Value = mean value + number of standard deviations specified
a. Μ ± 1σ of the observations lie between what two values?
Lower Value = 390 - 1(95) = 295
Upper Value = 390 + 1(95) = 485
b. Μ ± 2σ of the observations lie between what two values?
Lower Value = 390 - 2(95) = 200
Upper Value = 390 + 2(95) = 580
c. Μ ± 3σ of the observations lie between what two values?
Lower Value = 390 - 3(95) = 105
Upper Value = 390 + 3(95) = 675

Answer:
6x = 162 or 162 = 6x
Step-by-step explanation:
x = days, since how many days is unknown, we substitute it as x
Answer:
y = 2x and y = -7x +9
Step-by-step explanation:
The two "linear" functions are those that have a constant rate of change. Actually, the slope (inclination) they show when plotted is that "rate of change".
The function : y = 2x, has a constant positive rate given by its slope (2).
The function : y= -7x +9 has a constant negative rate given by its slope (-7)
The other two functions are quadratic, represented by parabolas, and therefore don't have a constant rate of change.
