Answer:
0.01 to 0.99, the multiplier in scientific notation always has to be a decimal less than 1 and greater than 0.
Step-by-step explanation:
To solve for the minimum score required, we find for the z
score value at P = 0.97 (top 3%). The z score is:
z = 1.88
Then we use the formula to find for X:
z = (X – u) / s
1.88 = (X – 400) / 100
X = 588
<span>You have to score at least 588.</span>
For the solid line it is (0,-3), (0,3), (-3,4)
for the dotted line it is (-1,-1), (-3,-2), (-3,2)
hope this helps don't know for sure though if its right i just did the best i could do.
