To answer this question, you need to write a linear equation (because the graph is a visibly straight line) that models this situation, then plug in 12.
The general format for a linear equation is y=mx+b, where m is the slope and b is the y intercept. The y intercept of a line is where it crosses the y axis; for this line, it crosses the y axis at (0, 0) so the y intercept is 0.
To find the slope, use the slope equation: (y2-y1)/(x2-x1). For y1, y2, x1, and x2, just pick any two points on the line. We will use (1, 30) and (2, 60):
(60-30)/(2-1)
30/1
30
The line is y=30x.
Plug in 12 for x:
y=30(12)
y=360
3). 360
Hope this helps!!
Answer:
3/10
Step-by-step explanation:
Let's assume;
30 ml of Orange Juice + 45 ml of Apple Juice + 25 ml of Coconut milk = 1 glass of Cocktail
30 ml : 45 ml : 25 ml = 1
30 + 45 + 25 = 100 ml = 1 glass of Cocktail
Orange juice proportion = Amount of Orange Juice in ml ÷ 1 glass of Cocktail in ml
Orange Juice proportion = 30 ml ÷ 100 ml
= 3/10
12 is the answer
12 goes into all threee
Answer:
The confidence interval of standard deviation is: 
to 
Step-by-step explanation:
Given
See attachment for the formatted data
Solving (a): The mean
This is calculated as:
So, we have:
Solving (b): The standard deviation
This is calculated as:
--- approximated
Solving (c): 95% confidence interval of standard deviation
We have:
So:
Calculate the degree of freedom (df)
Determine the critical value at row and columns 
and 
So, we have:
---- at
--- at
So, the confidence interval of the standard deviation is:
to
