Answer:
inverse relation of x is f⁻(X) = (x+15)/-6
Step-by-step explanation:
move the decimal to the left 6 times and you'll get .028578
Answer: C
Step-by-step explanation:
<u>Given:</u>
Sample size (n) = 50
x = 12

Confidence level = 90%
α = 1 − 0.90 = 0.10
α/2 = 0.05

(from standard normal table)
90% Confidence interval is,

Therefore, 90% confidence interval for the true proportion of sophomores who favour the adoption of uniforms is C
I'm not sure I'll DM u when I get it
The slope of the given line is
.. (1 -(-3))/(4 -(-4)) = 4/8 = 1/2
Then the perpendicular line will have slope
.. m = -1/(1/2) = -2
The point-slope form of your line is
.. y -3 = -2(x +4) . . . . . . . . . . if you prefer y -y0 = m(x -x0)
.. y = -2(x +4) +3 . . . . . . . . . . if you prefer y = m(x -x0) +y0 as I do.
