Answer: 0.0688
Step-by-step explanation:
Given : Current research indicates that the distribution of the life expectancies of a certain protozoan is normal with a mean of 43 days and a standard deviation of 10.1 days.
i.e. and
Let x represents the life expectancies of a certain protozoan.
Sample size : n= 25
The probability that a simple random sample of 25 protozoa will have a mean life expectancy of 46 or more days. :-
[using z-value table]
Hence, the required probability = 0.0688
<h3>Therefore the equation of parabola is </h3><h3>x²=-128 y</h3>
Step-by-step explanation:
Given ,coordinate vertex of the parabola is (0,0) and coordinate focus is (0,-32)
Therefore the distance between vertex and focus is
= 32
Therefore the equation of parabola is
x²= -(4×32)y
⇒x²=-128 y
