Answer:
y = 11 1/2
Step-by-step explanation:
7y - 63 = y + 3
-y. -7
6y - 63 = 3
+ 63. + 63
6y = 69
/6. /6
y = 11 1/2
I think you have to multiply
Answer: the domain of the function in the table is 3<x>6 because with the coordinate points you gave, 3 is the lowest x value and 6 is the highest therfore x must be higher than 3 but lower than 6.
Step-by-step explanation:
Answer:
f(x)+41 f(-10)=7
Step-by-step explanation:
The sample variance for distribution of the means is 9
The average of the squared differences from the Mean is called Variance. Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value.
The Standard Deviation is a measure of how spread out numbers are.
Its symbol is σ (the Greek letter sigma)
Its formula is the square root of the Variance
Given: Standard Deviation = 3
Sample size = 36
∴ By formula we get
3 = √(Variance)
∴ 9 = Variance
Thus the sample variance for distribution of the means is 9
