dion flips a coin 20 times and records if it comes up heads. if getting heads is a success, what is the probability of a success

kolbaska11 [484]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

The probability of success (getting heads) on one roll DOESNT affect other rolls, so we need to find probability of getting a head in a roll.

Probability is defined as the number of favorable outcomes divided by the total number of outcomes.

Here, favorable outcome is getting a head. So, on one roll, getting a head is 1. Also, the total number of outcomes is either a head or a tail. So total number of outcomes is 2.

Thus,

P(Heads) = 1/2

A line is graphed below. Write an equation in the form y = mx + b that represents this line

galben [10]

<h3>Explanation</h3>

Slope-Intercept form

$y = mx + b \\ m = slope \\ b = y - intercept$

Calculate the slope with two given coordinate by using rise over run.

$\begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}$

These two coordinate points are part of the graph and can be used to find the slope.

$m = \frac{y_2 -y_1 }{x_2 - x_1}$

Substitute the coordinate points in the formula.

$m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2}$

Therefore, the slope is 2.

Rewrite the equation in slope-intercept.

$y = \frac{1}{2} x + b$

Calculate the y-intercept by substituting any given points in new rewritten equation.

$(x,y) = ( 0,2)$

I will be substituting these coordinate points in the equation.

$y = \frac{1}{2} x + b$

Substitute x = 0 and y = 5 in the equation.

$2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b$

Therefore the y-intercept is (0,2).

Rewrite the equation.

$y = \frac{1}{2} x + 2$

<h3>Answer</h3>

 $\large \boxed{y = \frac{1}{2} x + 2}$
