The correct answer is B) y + 9 = 2(x - 1)

In order to find this, simply take the point and the slope and plug into the base form of point-slope form.

y - y1 = m(x - x1)

Use the slope for m and the point for (x1, y1)

y + 9 = 2(x - 1)

Let x be a random variable from a binomial distribution with n = 40 and p = 0.9. If a normal approximation is appropriate, give

Dvinal [7]

Answer:

Step-by-step explanation:

Given that x is a random variable from a binomial distribution with n = 40 and p = 0.9.

We find that mean = np= 36 and variance = npq = 3.6

Std dev = square root of variance = 1.897

When we approximate binomial to normal we say

X' is Normal with mean = 36 and std dev = 1.897

X' is N(36, 1.897)

Note:

The condition for binomial approximating to normal is p should be close to 1/2

Here p is 0.9 and also nq=4 is very small.

So normal approximation may not give accurate results.

Which is the graph of f(x) = one-fourth(4)x?

frez [133]

Answer:

The image shows the graph for given function.

Step-by-step explanation:

We are given the following information in the question:

$f(x) = \displaystyle\frac{1}{4}4^x$

It is clear function is an exponential function and have shape similar to exponential function.

An exponential function is of the form:

$f(x) = b^x$ ,

where b is a parameter of the function and read as b raised to the power x.

The exponential function enjoys the following properties:

If 0 < b < 1, then the graph decreases as we move from left to right.
If b > 1, then the graph will increase as we move from left to right.
