Answer:
16 minutes per meter
Step-by-step explanation:
Depth = 3/8 meters
Time taken = 6 minutes
What is the unit rate in minutes per meter?
Time taken per depth = minutes per meter
Unit rate in minutes per meter = 6 minutes ÷ 3/8 meters
= 6 minutes × 8/3 meters
= 48/3
= 16 minutes per meter
Answer:
a. always
Step-by-step explanation:
In a simple linear regression, the slope measures the steepness of the linear relationship between the two variables, it ranges from (-∞ to +∞ ) while the correlation coefficient measures the tightness of the linear relationship between the two variables, it ranges from (-1 to +1 ).
So the correlation coefficient and the slope will always have the same sign though their values might differ.
Answer: 5/22x
Step-by-step explanation:
Answer:
36 animals
Step-by-step explanation:
g = goats = 1/3 h where h = herd
s = sheep = g + 12 = 1/3 h + 12 because g = 1/3 h
added together = h
1/3 h + 1/3h+12 = h
2/3 h + 12 = h
12 = 1/3 h
36 = h
Answer:
x = -3
Step-by-step explanation:
What you do is get x by itself.
1/4(8x - 4) = 5x + 8 <u>Distribute 1/4 to 8x and -4.</u>
2x - 1 = 5x + 8 <u>Subtract 5x on both sides.</u>
-3x -1 = 8 <u>Add -1 to both sides.</u>
-3x = 9 <u>Divide -3 on both sides.</u>
x = -3
