The probability is 0.69.
We find the z-scores that correspond with each end of the range we're looking for. To find a z-score, we use the formula:
Using a z-table (http://www.z-table.com) we see that the area under the curve left of the score 350 would be 0.228. The area under the curve left of the score 400 would be 0.918. To find just the range between 350 and 400, we subtract the area left of 350 from the area left of 400; this will give us just from 350 to 400:
0.918-0.228 = 0.69.
Simply you can answer it
area of trapezoid= area of triangle + area of triangle + area of rectangle
so,
area=( 1/2*2*12)*2+12*14
=24+12*14
=192in²
Answer:
its 24 C on edge
Step-by-step explanation:
i know im late but can i get braniest at least mine is correct and not the other guys
Answer: x=5 , y=3
steps:
3x-2(2x-7)=9
simplify
(-x+14=9)
isolate x for -x+14=9
x=5
y=2(5)-7
y=3
You not explaining it that well so i dont know what to look for sorry
