15.87% of the population does not meet the minimum standards.
We use z-scores to find this probability:
z=(X-μ)/σ = (85-100)/15 = -15/15 = -1
Using a z-table (http://www.-table.com) we see that the area to the left of, less than, this is 0.1587. This is 15.87%.
The trapezoid has one pair of parallel sides.
Answer:
Step-by-step explanation:
area of rectangle=length×width
=(x²+6x+3)×(3x²+4x-2)
=3x^4+(4+18)x³+(-2+24+9)x²+(-12+12)x-6
=3x^4+22x³+31x²-6
Answer:
Step-by-step explanation:
1. Graph point (2, 3)
2. Go down 3, 4 to the right or up 3 and 4 to the left
3. Repeat until you have about 3 to 4 points
4. Create a line
