Because ∠2 is a diameter away from arc ST, ST is two times larger than ∠2. So, the answer is:
m∠2 = 1/2(mST)
0 -2,infinity is the correct answer
B + 3/2*b + b + 45 + 2b - 90 + 90 = 540
Or, 4b + 3b/2 + 45 = 540
Or, (8b+3b)/2 = 495
Or, 11b = 990
Or, b = 90
Now,
b+45 = 135
3/2*b = 135
2b - 90 = 90
Answer:
The point estimate for estimating the true proportion of employees who prefer that plan is 0.436
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this problem, we have that:
Lower bound: 0.366
Upper bound: 0.506
Point estimate:
(0.366 + 0.506)/2 = 0.436
The point estimate for estimating the true proportion of employees who prefer that plan is 0.436
Answer:
The ladder needs to be 26 ft long.
Step-by-step explanation:
So pythag is

We have the height and distance from the window, so we need to find c
