Answer:
k = 3.33
Step-by-step explanation:
x = 2
y = 3
x - ky + 8 = 0
2 - k(3) + 8 = 0
2 - 3k + 8 = 0
10 - 3k = 0
<u>-10 -10</u>
-3k = -10
k = 3.33
Answer:
z ≈ 145.62
Step-by-step explanation:
using the sine ratio in the right triangle
sin18° = 
= 
( multiply both sides by z )
z × sin18° = 45 ( divide both sides by sin18° )
z = 
≈ 145.62 ( to the nearest hundredth )
I believe the answer would be 46 students
> 46 Students in Tom's school are Left-Handed
you keep the 2k
so 5(-45)5x is 5 * -45*5 = -1125
the answer is 2k+-1125x
Answer:
e= -5.41
Step-by-step explanation:
Hello!
In linear regression, a residual value is a distance between the observed values and the regression line.
The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).
e= Y - ^Y
e= 15.92 - 21.33 = -5.41
I hope it helps!
