Answer:
Step-by-step explanation:
Let's find a solution by understanding the following:
The acceleration rate is defined as the change of velocity within a time interval, which can be written as:
where:
A=acceleration rate
Vf=final velocity
Vi=initial velocity
T=time required for passing from Vi to Vf.
Using the problem's data we have:
Vf=65miles/hour
Vi=6miles/hour
T=14.8seconds
Using the acceleration rate equation we have:
, but look that velocities use 'hours' unit while 'T' uses 'seconds'.
So we need to transform 14.8seconds into Xhours, as follows:
Using X=0.0041hours in the previous equation instead of 14.8seconds we have:
In conclusion, the acceleration rate is
Answer:
0.2006
Step-by-step explanation:
The probability the first calculator is defective is 42/62.
The probability the second calculator is defective is 41/61.
The probability the third calculator is defective is 40/60.
The probability the fourth calculator is defective is 39/59.
The probability all four calculators are defective:
(42/62) (41/61) (40/60) (39/59) = 0.2006

Step-by-step explanation:
(distribute)
-3x -9 -3x + 3 + 8x = 4
(simplify)
2x -6 = 4
x=5
