Answer: 34%.
By definition of normal distribution, ≈68% of the data is within 1 standard deviation of the mean. Therefore 68% of IQs are between 85 and 115, and half of that is on the lower end, 85 to 100.
Answer:
w(2w+4)
Step-by-step explanation:
we know A = l * w
and Perimeter = 2l + 2w
we want to find l in terms of w
2l + 2w = 6w + 8
2l = 4w + 8
l = 2w + 4
so A = w * (2w + 4)
Parallel lines must have the same slope. However for them to be UNIQUE lines, ie different lines, they must have a different y-intercept.
So if we say generally that a line is y=mx+b where m is the slope and b is the y-intercept then these two unique parallel lines would be:
y1=mx+h and y2=mx+k
Where m is the same for both and each have unique constants h and k where they cross the y-axis
