Answer:
The standard deviation of the average fill volume of 21 bags is 0.0175 fluid ounces
Step-by-step explanation:
To calculate the standard deviation of the average fill volume of 21 bags, we simply divide the standard deviation by the square root of variable number
That will be 0.08/√21 = 0.0175 fluid ounces
X - 8 > -3
x - 8 + 8 > -3 + 8
x > 5
The answer is the third choice.
Answer:
b= 3a-c
Step-by-step explanation:
Solve for b.
a= 1/3(b+c)
multiplying both sides by 3.
3a= b+c
subtract c from both sides.
3a-c=b
or
b= 3a-c
The last one : y - 5 = (x - 6)
the equation of a line in point- slope form is
y - b = m(x - a )
where m is the slope and (a, b ) a point on the line
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 2, - 1 ) and (x₂, y₂ ) = (B(6, 5 )
m = = =
using (a, b ) = (6, 5 ), then
y - 5 = (x - 6 ) ← in point- slope form
