Answer:
3. 1/3
Step-by-step explanation:
Change the equation by isolating y
9y=3x-4
y=1/3x-4/9
this is slope intercept form.
y=mx+b
m=slope
∴slope=1/3
OR
your equation is in standard form Ax+By=C
slope=-A/B
-3/-9
1/3
∴slope is 1/3
(15,-10) (17,2)
(2+10)/(17-15)= 12/2 = 6
The slope is 6
Z = (X-Mean)/SD
<span>z1 = (580-600)/20 = - 1 </span>
<span>z2 = (620-600)/20 = + 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1*SD covers 68% of the values </span>
<span>Therefore, required percent is 68%
hopes this help :) :D :)</span>
