Answer:
y= 4x
Step-by-step explanation:
Slope-intercept form:
y=mx + b
Find the y-intercept (b).
8= 4(2) + b
8= 8 +b
8 - 8= 8 - 8 + b
0= b
Therefore, the equation of the line in slope-intercept form is:
y= 4x
16² = 18² + 19² - 2(18)(19)cos(z)
256 = 324 + 361 - (684)cos(z)
256 = 685 - (684)cos(z)
-429 = -684cos(z)
cos(z) = -429/-684
z = cos⁻¹ (0.627)
z = cos⁻¹ (cos 51) [ Cos 51 = 0.627 ]
z = 51
In short, Your Answer would be: 51
Hope this helps!
tdf will approach z.
Suppose that for a particular family of T-distributions that t2 has 2 degrees of freedom (df) and t9 has 9 degrees of freedom.

(192+214+250+x)/4=225
solve for x
(656 + x)/4= 225
656+x = 225*4
656 + x = 900
x = 900 - 656
x= 244
I dont really know maybe use the diagram it might help a lil
