Answer:
positive correlation
Explanation:
The correlation in where x and y value increases makes a line going upwards to the right side. This means that it is a positive correlation.
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
Answer:
See below
Step-by-step explanation:
<u>Given relationship:</u>
a) r = 3, d = 4
- t = d/r = 4/3 h = 1 h 20 min
b) d = 4 miles, rate = r
- t = 4/r, domain is r and must be greater than zero
c) d = 4 miles, time = t
- r = d/t = 4/t, domain is t and it must be greater than zero
d) t = 3 h, rate = r
- d = rt = 3r, domain is r and can be anything greater than zero
