Answer:
(65.5775 , 72.2225)
Step-by-step explanation:
Confidence Interval is the range around sample mean, likely to consist the population parameter.
Formula = x' <u>+</u> z (s / √n)
= 68.9 <u>+</u> 2.5 (8.3 / √39)
= 68.9 <u>+</u> 3.3225
(65.5775 , 72.2225)
(0,2)(-2,0)
slope = (0 - 2) / -2 - 0) = -2/-2 = 1
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
equation is : y = x + 2......solid line, means there is an equal sign....shaded below the line means less then....
ur inequality for this line is : y < = x + 2
(0,6)(3,0)
slope = (0 - 6) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(0,6)...x = 0 and y = 6
sub and find b, the y int
6 = -2(0) + b
6 = b
ur equation is : y = -2x + 6....dashed line means there is no equal sign...and shading below the line means less then...
so ur inequality of this line is : y < -2x + 6
In summary, ur 2 inequalities are : y < = x + 2 and y < -2x + 6
He earn around $36629 as intrest.
so usually intrested is calculated according to the percentage.
some monthly and annually.
so you cannot have negative number for %
and he gained then there no way .then have negative number..
