I don’t know what your trying to find but you basically create an equation, like this
3x+5x=80
and solve which would result in x=10
so there is
30 geckos
and
50 anole lizards
Answer and Step-by-step explanation:
Theoretical probability is expected probability of an occurrence hence the name theoretical. It is theoretical and not practical as it has not been experimented or actually become practical. Experimental probability on the other hand is probability that has been experimented- it is the result of test of probability on the actual population.
In the case above, the theoretical which is the expected probability that has not been experimented is 1/2 of getting Red cards. This probability is theoretical and therefore may change when tested. Hence the different result of 7 Red and 13 blacks with 20 cards picked when experimented
There is no picture here that or you need to be more pacific
<em>50/50 CHANCE.</em>
<u>With a coin that contains two </u><u>sides</u><u> the probability of heads and tails is always fifty percent for each side</u>. One hundred divided by two would be 50.
Answer: x = 123
--------------------------------------------
--------------------------------------------
Here are the basic steps:
Step 1) Find the measure of angle 7 (near the 35 degree angle)
Step 2) Find angle 6 (in the center; bottom angle)
Step 3) Use angle 6 to find the value of x
-----------------
Let's go through those steps mentioned
-----------------
Step 1) Finding the measure of angle 7
We see that the 35 degree angle and angle 7 combine to form a 90 right angle. So they must add to 90 degrees
(angle 7) + 35 = 90
(angle 7) + 35 - 35 = 90 - 35
angle 7 = 55
So angle 7 is 55 degrees. We'll use it on the next step
-----------------
Step 2) Finding the measure of angle 6
We'll use the result from step 1. The triangle with angle 7, angle 6, and the 68 degree angle will be focused on here. Recall that for any triangle, the three angles must add to 180 degrees.
So,
(angle 7) + (angle 6) + 68 = 180
(55) + (angle 6) + 68 = 180
(angle 6) + 55 + 68 = 180
(angle 6) + 123 = 180
(angle 6) + 123 - 123 = 180 - 123
angle 6 = 57
So we now know that angle 6 is 57 degrees
-----------------
Step 3) Find x
We now use the fact that angle 6 and angle x are a linear pair. They combine to form a straight line, or straight angle. In other words they add to 180 degrees (they are supplementary angles)
So,
(angle 6) + x = 180
(57) + x = 180
x + 57 = 180
x + 57 - 57 = 180 - 57
x + 57 - 57 = 123
x = 123
-----------------
Side note: we can use the exterior angle theorem to skip over step 2. To do this, we add up angle 7 (which was 55 degrees) to 68 to get 123 degrees which is the same answer.
