Answer:
No
Step-by-step explanation:
y = 32 – 1 is not true to (1,2) because y=2 and 2 does not equal 31.
C ≈ 37.7 (I think? Not very good with math, haha)
You're looking for

such that

Transforming the standard normal distribution, you have

where

is the cutoff score in terms of this new distribution. The z-score corresponding to a probability of 0.20 is approximately

, which means the cutoff test score is

Rounding to the nearest whole point, a score of about 114 is the bare minimum requirement to not have to take the remedial course.
Let
x = number of minutes of local calls.
y = number of minutes of international calls.
By writing the system of equations we have:
0.06x + 0.15y = 69.84
x + y = 852
Solving the system
Clear y from equation two
y = 852-x
Replace y in equation 1
0.06x + 0.15 (852-x) = 69.84
Clear x
0.06x + 127.8 - 0.15x = 69.84
127.8 - 69.84 = 0.15x -0.06x
57.96 = 0.09x
x = 57.96 / 0.09 = 644
x = 644
Replace x in any of the two equations and clear y:
x + y = 852
y = 852-644
y = 208
answer
number of minutes of local calls = 644
number of minutes of international calls = 208
chord distance center theorem
if two chords are equidistant from the center, namely, they're the same distance away from the center of the circle, then those chords are twins.
so, therefore if RA is 9.3, VI her twin is also.
