Chocolate to Vanilla is 5:4
5*6=30
4*6=24
30:24
So, 30 chocolate cones
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.

Answer:
A) In the table, we can see that from one pair (x,y) to the next one, x-variable increase in 10 units and y-variable increase in 80 units. This is valid for all pairs (x,y), which mean that there is a linear relationship between these variables.
B) slope (m) = y-variable increment / x-variable increment = 80/10 = 8
the coordintae (0, 120) indicates that 120 is the y-intercept (b) of the line
Equation of a line in the slope y-intercept form:
y = mx + b
y = 8x + 120
C) The y-intercept indicates the number of products produced monthly without employees.
The slope indicates how much the production increase with a new employee.
