Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
The standard deviation error generated on small random sample size is:
σ (error) = σ/√(n)
σ (error) = 15/√(36) ===σ (error) = 2.5
Answer:
No
Step-by-step explanation:
A function is a relation in which no two ordered pairs have the same first element.
A function associates each element in its domain with one and only one element in its range.
