We have
425 corresponds to a z of
575 corresponds to
So we want the area of the standard Gaussian between -3/4 and 3/4.
We look up z in the standard normal table, the one that starts with 0 at z=0 and increases. That's the integral from 0 to z of the standard Gaussian.
For z=0.75 we get p=0.2734. So the probability, which is the integral from -3/4 to 3/4, is double that, 0.5468.
Answer: 55%
Answer:
Step-by-step explanation:
all correct
Let’s take a look at the definitions of all of these categories of polygon:
A rhombus is a quadrilateral with four equal-length sides
A trapezoid is a quadrilateral with at least one pair of parallel sides
A kite is a quadrilateral with two pairs of equal sides, where those sides are adjacent to each other
A quadrilateral is a four-sided polygon
And let’s compare our definitions with the figure:
- None of the sides of the figure are equal to each other, so we it can’t be a rhombus
- The slopes of all of the sides are different, so the figure can’t have a pair of parallel lines, ruling out the chance that it’s a trapezoid
- That first bullet point also rules out the possibility that our figure is a kite
- Our figure *is* a four-sided polygon though, so it meets the requirements for a quadrilateral
So, the only label that works for this figure is a *quadrilateral*.
