Answer. Option A. y>3x+2
Explanation. Because the line is dotted, we know it is a > equation. We know that in slope-intercept form, the mx stands for is the slope (rise over run), by looking at the graph, we find that the slope is in fact 3 (or 3/1). For the second part of the equation, we know it’s the y-intercept; therefore, option A is correct because the y-intercept is in fact 2. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.

<h3>Function 1 : </h3>

Observe the abscicca and ordinates

*Note that:- y-coordinate is ordinate and x-coordinate is abscicca.

The ordinate having 0 as abscicca in function 1 is (0,1), Thus.. The y-intercept is 1

<h3>Function 2 : </h3>

Observe the graph and mark the point where function meets y-axis

*Note that:- The point of the graph where the function meets y-axis is called y-intercept.

The point where the function meets is (0,1). Therefore, The y-intercept of function 2 is also 1

$\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}$

Thus, Option C is the correct choice!!~

Trevor tosses a coin then rolls a die

schepotkina [342]

The probability of tossing heads and not rolling 5 is 31/32.

Let us assume a coin is fair and 2-sided.

A coin usually flips heads or tails.

Then to flip heads or tails equals 1/2

Consider flipping a coin 5 times.

Since a coin flip has two outcomes, then a coin flip 5 times has 2

5 =32 outcomes.

We may show the outcomes, e.g. use sample space S.

Then (1)S=(H,H,H,H,H),(H,H,H,H,T),…,(T,H,H,H,H),(T,T,T,T,T)

It must follow ∣S∣=32.

A helpful way to see may be S=H, T 5=H, Tx…Hx, T.

<h3>What is the formula for probability?</h3>

P(S)=1-P(A)

If you see the complement of at least 1 tail means 0 tails or 5 heads, then we must surely see 1 outcome, e.g. all heads.

Then it must follow at least one tail that has 31 outcomes,e.g.32–1=31.

To find or compute the probability, then fevorable possible in outcomes.

It means 31/32,

P(E)=1– 32/1= 32/31
