Answer:
y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.
Step-by-step explanation:
<em>-7 -5 / 4 -2 / -12/2 </em>
<em>-12/2 = -6 </em>
<em>Slope: -6x </em>
<em>5 = 2(-6) + b</em>
<em>5 = -12 + b </em>
<em>-12 + 17 = 5 </em>
<em>Slope intercept Form: y = -6x + 17</em>
Answer:
208.85
Step-by-step explanation:
It is 208.85 because when you have .8 + .05 =.85
Answer:
625
Step-by-step explanation:
<span>The computation for the confidence level = (18/20) x 100% =
90 %, the E or the margin error = 0.023 and the p = to 0.71. Confidence
interval can be achieved by using the formula (p-E, p+E) = (0.71-0.025,
0.71+0.025). Therefore, the confidence interval is (0.685,0.735).</span>
