D = 117
because angle 63 = angle 37+a because they are vertical angles,
therefore angle angle 37+a= angle b because they are corresponding angles
so if angle b=63 then angle d=117, so that together they equal 180, a supplementary angle.
Answer: 24
Step-by-step explanation: 18/3 =6 6x4=24
Answer: The point estimate for this population proportion is 0.2
Step-by-step explanation:
The point estimate for this population proportion is also referred to as the sample proportion. This is also known as the probability of success, p. The formula for determining p is expressed as
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 200
x = 40
p = 40/200 = 0.2
Answer:
B
Step-by-step explanation:
1.25 is incorrect becuase 25% is .25 not 1.25
Consider the geometric series S(x)=1+2(x−3)+4(x−3)^2+8(x−3)^3+⋯
Giving your answer as an interval, find all values of x for which the series converges.
Now assuming that x is in your interval above, find a simple formula for S(x).
