Answer:
Mark point E where the circle intersects segment BC
Step-by-step explanation:
Apparently, Bill is using "technology" to perform the same steps that he would use with compass and straightedge. Those steps involve finding a point equidistant from the rays BD and BC. That is generally done by finding the intersection point(s) of circles centered at D and "E", where "E" is the intersection point of the circle B with segment BC.
Bill's next step is to mark point E, so he can use it as the center of one of the circles just described.

<em>Comment on Bill's "technology"</em>
In the technology I would use for this purpose, the next step would be "select the angle bisector tool."
Answer:
Step-by-step explanation:
5%×g= 5g/100
g-5g/100
Answer:
a) 18.98%
b) -0.2142
c) (183000,407000)
d) (127000,463000)
Step-by-step explanation:
We are given the following in the question:
Mean, μ = $295,000
Standard Deviation, σ = $56,000
a) Coefficient of variation
b) z-score
x = $283,000
Formula:
Putting the value, we get,
c) 95% interval
Empirical Rule:
- According to this rule almost all the data lies within three standard deviation of mean for a normal distribution.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviation of mean.
Thus, the price of 95% of the homes lies between $183,000 and $407,000.
d) 90% interval
Chebyshev's Rule:
- For a non normal data atleast percent of data lies within k standard deviation of mean.
- For k = 3
Thus, 90% of prices will lies within three standard deviation of mean.
According to Chebyshev's Theorem 90% of prices will lie between $127,000 and $463,000.
Answer:
B. 2j+12
Step-by-step explanation:
Twice the number = 2j
By 12 = +12
