Answer: cumulative frequency
Step-by-step explanation:
- A frequency is the number of times a data value occurs.
- A relative frequency is the fraction or proportion of times an answer occurs.
- The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.
In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.
Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.
Answer:
7 1/2
Step-by-step explanation:
convert mixed numbers to fractions to get 1/2 and 15/1
then, multiply the two to get 15/2
then simplify for the answer 7 1/2
Answer:
Infinite or 2
Step-by-step explanation:
Since, we can take any side we want, infinite number of triangles can be formed.
However, if more than one similar triangles aren't allowed, then the value is (3-1)! = 2! = 2.
Answer:
The answer is (4x - 3)/(x + 6)
Step-by-step explanation:
∵ (4x² - 7x + 3)/(x² + 5x - 6)
Factorize the numerator:
4x² - 7x + 3 = (4x - 3)(x - 1)
Factorize the denominator:
x² + 5x - 6 = (x - 1)(x + 6)
∴ (4x - 3)(x - 1)/(x - 1)(x + 6) ⇒ reduce (x - 1) from in up and down
∴ The answer is (4x - 3)/(x + 6) ⇒ the fourth answer
Answer: tan x
Step-by-step explanation: An angle determines if a side is opposite the angle, or adjacent the angle. Since p/a is something to do with the tangent, as it is not using the hypotenuse (the longest side.) Tangent is Opposite/Adjacent, while Sine is Opposite/Hypotenuse and Cosine is Adjacent/Hypotenuse. The only thing that makes sense is tangent.
So, that leaves us with either tan y or tan x. Well, with x, the angle that x points to (which is the opposite side) is p, and the adjacent is a, so p/a must be Tangent(x) since it is Opposite/Adjacent sides.
Only if it was r/p would it be tan y, since r becomes the opposite and p becomes the adjacent.
