Answer: OPTION C
Step-by-step explanation:
To solve the exercise shown in the image attached, you need to subtract the functions f(x) and g(x).
Keeping the above on mind, you have:
You must distribute the negative sign and then you must add the like terms, therefore, you obtain:
Answer:
Choice c is correct.
Step-by-step explanation:
We have given two functions:
f(x) = (2x²+ 2)
g(x) = (x²-1)
We have to find (f-g)(x).
(f-g)(x) = ( 2x²+ 2) - ( x²-1)
(f-g)(x) = 2x² + 2 - x²+1
(f-g)(x) = x²+3 is the correct answer.
Answer:
A. Mean = 402.5
B. Variance = 77,556.25
C. Standard Deviation = 278.49
Step-by-step explanation:
Let's calculate the mean, variance and standard deviation of the set of numbers given:
A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 = 402.5
B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =77,556.25
C. Standard Deviation = √Variance = √77,556.25 = 278.49
Answer:
1. 45⠀= -357.5⠀= 127,806.3⠀mean = 402.5
2. 340⠀= -62.5⠀ = 3,906.3⠀variance = 77,556.3
3. 400⠀= -2.5⠀= 6.3⠀deviation = 278.5
4. 825⠀= 422.5⠀= 178, 506⠀n = 4
Σ X = 1,610⠀X = 402.5⠀Σ (X - X)2 = 310,225.2
