Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)
The values of the cummulative distribution function of the standard Normal random variable, lets denote it 
are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600
Hence, the proportion of scores reported as 1600 is 0.0032.

Step-by-step explanation:
So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. <span>And how much will she pay?
Solution:</span> <span><span>
1. </span>19 for each t-shirt</span> <span><span>
2. </span>Total of $38 if not provided with 30% off</span>
<span><span>3. </span>19 x 0.3 = 5.7</span>
<span><span>4. </span>Hence 30% of $19 is $5.7</span>
<span><span>5. </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span>
6. </span>19 – 5.7 = $13.3</span> <span><span>
7. </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span>
8. </span>19 + 13.3 = 32.3</span>
<span><span>9. </span>Conclusively, she will pay $32.3 for the shirts.</span>

Step-by-step explanation:
Parallel lines are lines of equal distance apart (equidistant), that are on the same plane but they never meet
Perpendicular lines meet thus they are not parallel lines
Also, lines that intersect , meet, thus they are not parallel lines
