The correlation coefficient would not change when the units of one of the variable are different in the two cases.
Answer:
x= 7
x=6
Step-by-step explanation:
5+2x=19
Subtract 5 from both sides
so...
2x=14
then divide by two to isolate the x
so..
x=7
4x+3=27
Subtract 3 from both sides
so...
4x=24
then divide by 4 to isolate the x
so....
x=6
a dodecagon has 12 sides, now, if we take a circular 360° and divide into 12 even parts, we get 360/12 = 30, 5 of those angles added up will just be 150°, Check the picture below.
