Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
Answer: It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
Step-by-step explanation:
Since we have given that
Mean = 98.20°F
Standard deviation = 0.62°F
If Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to be a fever.
So,
So, using the normal distribution, we first find the value of z.
Since z = 3.87
So, p = 0.0001 =0.1%
So,It is such a small percentage of the population that would be considered to have fever at that level.
So, it is not appropriate stringent standard.
