<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Standard deviation = \sqrt{(n*p)(1 - p)}

Substitute the values in:

\sqrt{(500 *0.84)(1-0.84)} = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.

A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is la
andriy [413]

Answer:

Initial value is \frac{1}{2}.

Step-by-step explanation:

Let us assume that the exponential function is f(x) = a(b)^{x} ...... (1)

Now, the point (0,\frac{1}{2}) will satisfy the above equation.

Now, this point on the graph of the exponential function will be sufficient to find the initial value of the function (1) i.e. a.

Now, putting the value x = 0 and y = \frac{1}{2} in the equation (1) we get, f(x) = a(b)^{x}

⇒ \frac{1}{2} = a(b)^{0} = a

⇒ a = \frac{1}{2} (Answer)
