A local health clinic surveys its patients about their waterdrinking habits. It found the data is normally distributed,the mean
1 answer:
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
water drinking habits:
mean = 62 ounces
standard deviation = 5.2 ounces
Step 02:
normally distribution:
95% ===> 2 SD
(62 + 5.2 + 5.2) ounces = 72.4 ounces ==> + 2 SD
(62 - 5.2 - 5.2) ounces = 51.6 ounces ==> - 2 SD
The answer is:
51.6 ounces - 72.4 ounces

Answer:
y = 6x + 12
Step-by-step explanation:
We require the midpoint M and slope of AB
Using the midpoint formula, then
M = [ (3 - 9) ,
(- 7 - 5) ] = (- 3, - 6 )
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = A(3, - 7) and (x₂, y₂ ) = B(- 9, - 5)
m = =
= -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 6
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 , thus
y = 6x + c ← is the partial equation
To find c substitute M(- 3, - 6) into the partial equation
- 6 = - 18 + c ⇒ c = - 6 + 18 = 12
y = 6x + 12 ← equation of perpendicular bisector
