Answer:
yeet
Step-by-step explanation:
This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30
The answer is letter C.) 603.40
The minimum required score can solved using the equation
<span>MRS = mean + (zscore)(SD)
where z score of 0.03 is 1.88
</span>MRS <span>= </span>500 + (1.88)(55)
MRS = <span>603.40
