Answer:
you can simplify rations just like you simplify fractions. Whenever you are able to evenly divide both parts of the ratio with out changing the equation's answer, you are able to.
for example
if it were 3:6, you can simplify this by dividing these both by 3, leaving you with 1:2.
Answer:
1. Right angle triangle, 2. One triangle, 3. No triangle
Step-by-step explanation:
1. Has a 90-degree angle which makes it a right-angle triangle.
2. 30 + 60 + 90 = 180 degrees. Hence it satisfies the angle sum property so it is a triangle, a right-angle triangle.
3. It does not form a triangle as it does not satisfy the triangle inequality property, which is the sum of the two smaller sides should be greater than the larger side. 2 + 4 = 6, which is smaller than 7.
If the blocks were 9 different colors, then there would be
9 !(factorial) = 362,880 different ways to line them up.
But for each different line-up, there are 5! =120 ways to arrange
the green blocks and you can't tell these apart, 2!= 2 ways to arrange
the white blocks and you can't tell these apart, and 2!=2 ways to arrange
the orange blocks and you can't tell these apart.
So the number of distinct, recognizable ways to arrange all 9 blocks
is
(9!) / (5! · 2! · 2!) = (362,880) / (120 · 2 · 2) = 756 ways.
A. You would just get a lot of names back from people, thinking they have the most time playing instruments.
B. This question is not a statistically accurate question if you would like statistical answers back.
Statistical question definition:
A statistical question is one that can be answered by collecting data and where there will be variability in that data. For example, there will likely be variability in the data collected to answer the question,
The question to ask to get statistical answers back would be: How many hours do you play the instrument a day?
Each student would answer and you would see who has the most hours.
