Answer:
The formula y = mx + b is said to be a linear function. That means the graph of this function will be a straight line on the (x, y) plane. When the function for a line is expressed this way, we call it the 'slope-intercept form
Step-by-step explanation:
Answer: 5400 miles
Step-by-step explanation:
there are 60 seconds in a minute so you multiply 15x60 to get 900 which is the amount of miles it travels a minute. Then, since it's 6 minutes, you multiply 900 by 6 to get 5400 miles
Their closing speed is the total of the speed of the bus and the speed of the car:
... closing speed = (bus speed) + (1.4 times bus speed) = 2.4 × bus speed
The closing time is inversely proportional to the closing speed. When the bus alone covers the distance, the time required is 40 minutes. When the distance is covered 2.4 times as fast, the closing time is
... (40 min)/2.4 = 16 2/3 minutes
The vehicles will meet 16 minutes and 40 seconds after they start..
Answer:
the residual is 0.2032
Step-by-step explanation:
The regression line has been given as:
Y^ = 0.00753X-0.06759
The paired observation for X is (31, 0.369)
The value of X is the empathy score under subject 15 = 31
The value of the brain activity under subject 15 is 0.369
So we have y^ = 0.00753(31) - 0.06759
= 0.1658
Then the residual = y - y^
= 0.369 - 0.1658
= 0.2032
Therefore the residual is 0.2032
