Answer:
Population standard deviation (σ) = 0.3 in
Step-by-step explanation:
Sample mean = 3.07 in
Sample standard deviation (s) = 0.21 in
Sample size (n) = 62 cups
Population standard deviation (σ) = ?
The point estimate for the population standard deviation is given by sample standard deviation divided by the square root of the sample size:
I don't have graphing paper but with what I have done is made a small graph on a normal piece of paper from 10 to -10 on both the y and x-axis if you do it correctly it should be a rectangle
Ex 2) -27 + 28w
Ex 4) -13m + 21
Ex 6) 9(3x + y)
Ex 8) -6(3a + 5)
Ex 10) c - 17= 3
Ex 12) n= -27
Ex 14) v= 5
Ex 16)

Equation: 1/3a = 5
Answer: 15 years old
Answer: x = -19
Step-by-step explanation:
-4(x + 1) - 3 = - 3(x - 4). original equation
-4x -4 -3 = -3x + 12 distributed terms into the parentheses
-4x -7 = -3x + 12 added together terms (simplified terms)
-4x = -3x + 19 added term to the other side of the equation
-1x = 19 added term to the other side of the equation again
x = -19 divided by negative one
