Total students 5+16+42+22+5 = 90
0-1's probability is 5 / 90 = 5.5% about
2-3's probability is 16 / 90 = 17.7% about
4-5's probability is 42 / 60 = 46.6% about
6-7's probability is 22 / 90 = 24.4% about
8+'s probability is 5 / 90 = 5.5% about
(percentages not rounded, just cut off at the first decimal)
The answer is -3x^2+18x-30
Answer: 86 degree
Step-by-step explanation:
The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree
P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree
The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree
95 + 160 + 88 + 91 = 434 degree
540 - 434 = 106 degree
180 - 106 = 94 degree
So the last inward degree is 94
Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree
so X is 86 degree
Sorry if this was too confusing:)
