Answer:
-0.89 (i think)
Step-by-step explanation:
Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89
If its wrong then i'm not a smart person, and it's -0.15
Answer:
1.5 hours or 90 minutes
Step-by-step explanation:
384 km: 4 hours
divide both sides by 4
96 km: 1 hour
multiply both sides by 1.5
144 km: 1.5 hours
Given:
Tom's earnings: x
Jan's earnings: 2x - 150
Total earnings: 1380
x + 2x - 150 = 1380
3x = 1380 + 150
3x = 1530
3x/3 = 1530/3
x = 510
Tom's earnings: x = 510
Jan's earnings: 2x - 150 = 2(510) - 150 = 1,020 - 150 = 870
total earnings: 1,380
510 + 870 = 1,380
1,380 = 1,380
Answer:
b = 
Step-by-step explanation:
Given
y =
b + 10
Multiply through by 8 to clear the fraction
8y = 5b + 80 ( subtract 80 from both sides )
8y - 80 = 5b ( divide both sides by 5 )
= b
