Answer:
f(x) = 
Step-by-step explanation:
The given options are,
a) f(x) = 
b) f(x) = 
c) f(x) = 
d) f(x) = 
Now, clearly a) is a monotonically increasing function, hence discarded, and both of c) and d) don't pass through (0, 1) hence they are also discarded.
Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.

Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
Let the third side be x , then
x² + 6² = (2
)²
x² + 36 = 136 ( subtract 36 from both sides )
x² = 100 ( take the square root of both sides )
x =
= 10
Answer:
a) 0.1178
Step-by-step explanation:
The calculation is shown below:-
Mean = np
= 50 × 0.35
= 17.5
Standard deviation is
=

=

= 3.373
Therefore, as we know that
P which is Less than 14
So,
= P(X < 13.5)
= P(z < (13.5 - 17.5) ÷ 3.373
= P(z < -1.186)
= 0.1178
Hence, the correct option is a. 0.1178
basically we used the above formulas i.e mean and standard deviation
