Answer:
Three different ways (to : / )
Step-by-step explanation:
Examples:
3 to 5
3:5
3/5
The answer is the first one
is the equation in slope intercept form
<em><u>Solution:</u></em>
Given points are (0, 10) and (3, 2)
We have to find the slope intercept form
Let us first find the slope of line
<em><u>The slope of line is given as:</u></em>
Here,
<em><u>Substituting the values we get,</u></em>
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ------- eqn 1
Where, "m" is the slope of line and "c" is the y intercept
Substitute 
and (x , y) = (0, 10) in eqn 1
Thus the equation of line in slope intercept form is found
Answer:
Step-by-step explanation:
n = 400
Proportion p = 229/400= 0.5725
For 95% confidence interval we use Z value as 1.96
Std error = 0.025
margin of error = 1.96*0.025
Confidence interval 95% = 0.5725±Margin of error
= (0.524, 0.621)
b) When smiled x becomes 277
p = 0.6925
Std error = 0.023
Margin of error= 1.96*0.023
Confidence interval = (0.647, 0.738)
Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.
