If two 6-sided dice are rolled what is the probability that both numbers will be even?

1 answer:

3 0

The probability of one dice rolling an even number is 1/2 as half the numbers are even. Since the events are independent, and there are 2 dice, we need to square 1/2 to get 1/4, assuming they are both fair dice

Find 72 degrees and 40 degrees from the picture

polet [3.4K]

Answer:a) 5 sides

b) 9 sides

Step-by-step explanation:

a) Since the polygon is a regular polygon, all the interior angles are equal. If one exterior angle is 72 degrees, the interior angle would be

180 - 72 = 108 degrees(sum of the angles on a straight line is 180 degrees)

The sum of the interior angles of a polygon is expressed as

180(n - 2)

Where n represents the number of sides that the polygon has. Since the interior angles are equal, then

108n = 180(n - 2)

108n = 180n - 360

180n - 108n = 360

72n = 360

n = 360/72 = 5

b) If one exterior angle is 40 degrees, the interior angle would be

180 - 40 = 140 degrees

Since the interior angles are equal, then

140n = 180(n - 2)

140n = 180n - 360

180n - 140n = 360

40n = 360

n = 360/40 = 9

If y=x-6 where changed to y=x+8 how would the graph of the new function compare with the first one ?

madreJ [45]

Answer:

The function $y=x+8$ is the function $y=x-6$ shifted 14 units up.

The graph of the first equation will be a line with slope 1 that intersects the y-axis at point (0,-6)

The graph of the second equation will be a line with slope 1 that intersects the y-axis at point (0,8)

Step-by-step explanation:

The equation of the line in slope intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

The first equation is:

$y=x-6$

The second equation is:

$y=x+8$

The parent function with the form $y=mx$ can be shifted up or shifted down k units.

When $y=mx+k$ the function is shifted k units up.

When $y=mx-k$ the function is shifted k units down.

Then, the function $y=x+8$ is obtained by adding k=14 to the function $y=x-6$ .

Both equation has the same slope, but the y-intercepts are different.

The graph of the first equation will be a line with slope 1 that intersects the y-axis at point (0,-6)

The graph of the second equation will be a line with slope 1 that intersects the y-axis at point (0,8)

What is 16a +24b in distributive property

Damm [24]

Well, first... you want to factor out the GCF, (Greatest Common Factor), which will end up being 8.

Then, you divide both 16a and 24b by 8.

Simplify each term, and your answer will be:

8(2a+3b)

Hope this helps. If you have any further questions, feel free to email me at ([email protected])
