Input is domain and output is co-domain.
An expression is said to be a function if for every input, there is only one output. In table B, for every input, you get different outputs. Therefore, table B is a function.
Answer:
[rad] 2.41
Step-by-step explanation:
Since it gave you the point and the angle to find, you simply just have to solve for the inverse of cot. Remember cot is the opposite of tan, so cot is cos/sin. In that case, we plug into the calc (in radians):
cot^-1(-√5/2)
And we should get 2.41 as our answer!
Answer:
Answer is 49
Step-by-step explanation:
Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
The exact answer in fraction from is 2/15
The approximate answer in decimal form is 0.1333 (rounded to four decimal places)
The decimal value 0.1333 is equivalent to 13.33%
These are three ways to say the same basic answer.
===============================================
Explanation:
We have 4 red cards and 6 blue cards giving 4+6 = 10 total.
The probability of picking not blue (aka picking red) is 4/10 because there are 4 red out of 10 total.
If we don't replace the card we picked, then we have 3 red left over out of 9 total. The probability of picking red again is 3/9
Multiply those fractions
(4/10)*(3/9) = (4*3)/(10*9) = 12/90
Now reduce
12/90 = (6*2)/(6*15) = 2/15
note how the GCF 6 cancels
Using a calculator,
2/15 = 0.1333 approximately
The '3's after the decimal point go on forever.
