The distribution will be skewed to the right because the mean is greater than the median.
Answer:
y = (3/2)x + 8
Step-by-step explanation:
Hi
First let's find the slope of the given line by converting to slope-intercept form:-
2x + 3y = 9
3y = -2x + 9
y = (-2/3)x + 3
From this we see that the slope is -2/3.
The slope of a line perpendicular to this one will be - 1 / (-2/3)
= 3/2. ( because for a line and its perpendicular, the slopes' product = -1).
Using the point-slope form to find the equation of this line
y - y1 = m(x - x1). Here m = slope and (x1, y1) is a point on the line.
Plugging in the given values , m = 3/2 , x1 = -2 and y1 = 5:-
y - 5 = 3/2 (x - -2)
y - 5 = 3/2x + 3
y = (3/2)x + 8 which is the equation in slope-intercept form.
Answer:
40%
Step-by-step explanation:
average cigerattess Bonux smoke per day=10
standard deviation of cigarattes=8
percent of the bronx smoke at least a pack of (20) cigarettes a day.=?
percent of the bronx smoke at least a pack of (20) cigarettes a day.=(8/20)*100=40%
