Well if X is < (greater than) -7 it must be 0 because if -15, -10, -7, -7.2, are all less than -7 then 0 is the best answer

The graph of which of the following equations contains the points (2, 3) and (3, 2)?
IceJOKER [234]

Answer:

(2, 3) lies on the line y = 5 - x.  

Step-by-step explanation:

Were there only two possible answer choices?

We can determine whether or not a given point, such as (2, 3), is contained in a function such as y = x - 1, by substituting the given coordinates 2 and 3 for x and y respectively; is the resulting equation true or false?

Check out (2, 3) and y = x - 1:  3 = 2 - 1, or 3 = 1.  False.  (2, 3) does not lie on the line y = x - 1.  Does (2, 3) lie on the line y = 5 - x?  Is 3 = 5 - 2 true?  Yes.  So (2, 3) lies on the line y = 5 - x.

Check out (2, 3) and y = 7 - 2x.  Is 3 = 7 - 2(1) true?  No, it is not true.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
sweet-ann [11.9K]

The value of the probability P(x > 2) is 0.8369

<h3>How to evaluate the probability?</h3>

The given parameters are:

n = 5

p =0.7

The probability is calculated as:

P(x) = ^nC_x *p^x * (1 - p)^x

Using the complement rule, we have:

P(x > 2) = 1 - P(0) - P(1) - P(2)

Where:

P(0) = ^5C_0 *0.7^0 * (1 - 0.7)^5

P(0) = 1 *1 * (1 - 0.7)^5 = 0.00243

P(1) = ^5C_1 *0.7^1 * (1 - 0.7)^4

P(1) = 5 *0.7^1 * (1 - 0.7)^4 = 0.02835

P(2) = ^5C_2 *0.7^2 * (1 - 0.7)^3

P(2) = 10 *0.7^2 * (1 - 0.7)^3 = 0.1323

Recall that:

P(x > 2) = 1 - P(0) - P(1) - P(2)

So, we have:

P(x > 2) = 1 - 0.00243 - 0.02835 - 0.1323

Evaluate

P(x > 2) = 0.83692

Approximate

P(x > 2) = 0.8369

Hence, the value of the probability P(x > 2) is 0.8369
