Answer:
<h2>31.25%.</h2>
Step-by-step explanation:
The experimental probability is the ratio between the number of times an event occurs and the total number of trials.
In this case, the total number of trials is 64, because Page roles it 64 times.
Notice that the probability is about one event or the other, that indicates we need to sum both events.
Multiplying by 100, we have a probability of 31.25%.
Therefore, the experimental probability of getting three or four is 31.25%.

Answer:</h3>
<u>It squares the amount you scaled it by.</u>
<h3>
Step-by-step explanation:</h3>
For example, imagine that you had 2 by 2 square, and then you put it through a scale factor of 2.
Now each side length would be double of what it once was.
But when you multiply the new lengths together, the area would be of 4 times more.
(Original Equation) 2 * 2 = 4
(Scale Factor of 2) 4 * 4 = 16
So when the scale factor is made, the area would be squared to the multiple that you scaled it by.
<em>***A square root is a number times itself.</em>
<em>(eg): 3 * 3 = </em><em>9</em>
<em> 15 * 15 = </em><em>225</em>
<em>9 and 225 would be the square root in these problems.</em>
Angles in a quadrilateral add up to 360. So subtract the 3 angles you know. 360-90-90-73=107
Answer:
71 degrees
Step-by-step explanation:
Hi there!
- Find ∠DBH (using the sum of interior angles in a triangle)
- Find ∠x (180-∠DHB)
<u>Triangle DBH</u>
The sum of all the interior angles in a triangle is equal to 180 degrees. Knowing this, we can solve for ∠DHB by subtracting 31 and 40 from 180:
180-31-40 = 109
Therefore, ∠DHB is 109 degrees.
<u>Angle x</u>
Because ∠x and ∠DHB make a straight angle, to find ∠x, we just have to subtract 109 from 180:
180-109 = 71
Therefore, x is 71 degrees.
I hope this helps!
