Answer:

Probability of getting at least one 2 equals 0.5177

Step-by-step explanation:

The probability of at least one success is

P=1-(1-p)^{n}

where,

'p' is probability of success of 1 trail

'n' is number of events

We have probability of getting 2 is 1/6 thus 'p' = 1/6

Applying values we get

P=1-(1-\frac{1}{6})^{4}\\\\P= 0.51177

Enter an inequality that represents the graph in the box.
jasenka [17]

Answer:

y > -3x + 6

Step-by-step explanation:

First, find the equation of the dashed line.  We can use y = mx + b, where m is the slope and b is the y-intercept.

Here, the y-intercept is (0, 6).  To find the slope, we need a second point on the line.  Let's choose (2, 0).

m = Δy / Δx

m = (6 − 0) / (0 − 2)

m = -3

So the equation of the dashed line is y = -3x + 6.

Now look which side of the line is shaded.  In this case, the area <em>above</em> the line is shaded.  So the inequality is:

y > -3x + 6

Please help me with this.
vitfil [10]

Answer:

15.6 inches

Step-by-step explanation:

Here we want to find the length of the missing side

Mathematically, we can use Pythagoras’ theorem

The theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Let the missing side be x

18 is the side that faces right angle and this is the hypotenuse

Thus, we have ;

x^2 + 9^2 = 18^2

x^2 = 324 - 81

x^2 = 243

x = √(243)

x = 15.6 in
