Answer:
Approximately 50% of the vehicle speeds were less than 42 mph
Step-by-step explanation:
The normal distribution is symmetric:
That is, 50% of the measures are below the mean and 50% of the measures are above the mean.
In this problem, we have that:
Mean = 42 mph
So
Approximately 50% of the vehicle speeds were less than 42 mph
Answer:
The sin of 20 degrees is 0.34202, the same as sin of 20 degrees in radians. To obtain 20 degrees in radian multiply 20° by / 180° = 1/9 . Sin 20degrees = sin (1/9 × .

Answer:
Step-by-step explanation:
The system has Infinitely many solutions.
Step-by-step explanation:
We need to find how many solutions are there in:

Let:

Adding eq(1) and eq(2)

Since a constant term is equal to constant term, so the system has Infinitely many solutions.
