Answer:97 rods
Step-by-step explanation:
The number of steel rods for 95% confidence level
E=3
Substituting values
Thus 97 rods is tested
Answer:
5<*line under* x >*line under*9
I think
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
If T is the midpoint, then that means its exactly 1/2 of the way between 2 points
this means we can set the 2 given values equal
4x - 3 = 2x + 7
first move like terms to the same side
2x = 10
x = 5
now that we know the length of x, we plug it back in to get the length
4x - 3 + 2x + 7 = 6x + 4
6(5) + 4 = 34
[ -100, ∞ ). as X decreases f of x approaches -100 asymptotically as X increases f of x increases without bound
