Answer:
0.16
Step-by-step explanation:
Given the data:
Students __ `Gr_9 __Gr_10 __ G_11 __G_12
Frequency : 152 ___130 ______ 80 ___98
The probability is :
Frequency of grade 11 / number of trials
80 / 500
Generally a 45 degree angle is the best angle. this yields the smallest triangle with a 6' fence vertical side. As the ladder reaches the wall, two similar triangles are resolved. the 45 degree angle that the ladder makes with the ground yields a 6x6 legged right triangle. Adding 5' to the ground makes the larger 45 degree triangle with a base of 5+6=11' side. Using the formula for Special Triangles, 45-45-90 gives the ladder a 11 times the Squareroot of 2 for its length.
The 5 is the same. The value is 50,000
