1 answer:
To solve this, we take the number of subjects who weren't diabetic, and then divide them by the total number of subjects who took the test:
Probability =
=
= 0.903225..
= 0.90 (rounded)
-------------------------------------------------------------------------------------------------------------
Answer:
So the probability of randomly selecting a subject who was not diabetic would be <u></u>0.90 (the final option)
-------------------------------------------------------------------------------------------------------------
<em>Note:
</em> <em>We only used the numbers under 'Negative Test', because the question wanted the probability 'given that the test result was negative'</em>
Probability =

Answer:
The differential equation becomes -
i.e.
Step-by-step explanation:
Given - The rate of change of the volume V of water in a tank with respect to time t is directly proportional to the cubed root of the volume.
To find - Write a differential equation that describes the relationship.
Proof -
Rate of change of volume V with respect to time t is represented by
Now,
Given that,
The rate of change of the volume V of water in a tank with respect to time t is directly proportional to the cubed root of the volume.
⇒ ∝
Now,
We know that, when we have to remove the Proportionality sign , we just put a constant sign.
Let k be any constant.
So,
The differential equation becomes -
i.e.
