Answer:
5.4%
Step-by-step explanation:
percent error = |(measured - actual value) / actual value * 100| = |(7.8-7.4) / 7.4 * 100| ≈ 5.4%
Answer: Score is 629
Step-by-step explanation: z value for P(x > 0,90) is 1,29
Average x is 500 and deviation is 100. Value of score p is solved from
z = (p - x) / s p = s·z· + x = 129 + 500 = 629
My teacher always taught me to set these problems up like a proportion
is / of = % / 100
24/ x = 16 / 100
16x = 2,400
Divide 2,400 by 16 and you get 150.
150 is the correct answer.
A trapezoid is a quadrilateral because it has 4 sides. A quadrilateral is not always a trapezoid because a quadrilateral can be any shape as long as it has four sides.
I may not make sense but I hoped this helped! :)
