Answer:
20160 ways
Probability = 0.0556
Step-by-step explanation:
We have 9 different letters, so the total number of words we can make is:
If we want just the words that begin with L and end with a vowel, we would have the first letter "locked", so we have 8 letters remaining, and it must end with a vowel, so the last "slot" has just 4 possible values (A, E, I or O). Then we would have 4 possible values for the last letter and 7 remaining letters in the middle of the word:
The probability is calculated by the division of the number of words we want over the total number of words:
Answer:
11248squaremeter
Step-by-step explanation:
A 180º rotation around the origin changes the coordinates from (x, y) to (-x, -y).
A translation 7 units up increases the y value by 7 units.
A reflection over the x-axis results in the y-values being opposites.
They intercept in two points.
The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)
The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..

If you know how the two graphs look like then you can understand why they intercept only two times.
Ratio: 72 to 126
can be turned into a fraction 72/126
we then simplify the fraction 72/126
72 ÷ 2 = 36
126 ÷ 2 = 63
36 ÷ 3 = 12
63 ÷ 3 = 21
72/126 ⇒ 36/63 ⇒ 12/21
ratio of 72 to 126 is 12 to 21.
72/126 = 0.5714
12/21 = 0.5714
