Answer:is there more info
Step-by-step explanation:
slope intercept form
y -y1 = m(x-x1)
y-3 =1/4 (x-4)
distribute
y-3 =1/4 x-1
stand form of a line is Ax +by =c
so subtract 1/4 x from each side
y -3 -1/4 x =-1
add 3 to each side
y-1/4 x =2
-1/4 x +y =2
I would multiply by -4 on both sides to make the 1st term positive and get rid of the fraction
x -4y = -8
Find the slope of the line that crosses through the points (-3, -4) and (2, -3).
slope = (y2-y1)/(x2-x1)
m = (-3--4)/(2--3)
m = (-3+4)/(2+3)
m =(1/5)
m=1/5
Answer:
The tea's actual cost is $116.25
Step-by-step explanation:
* Lets revise how to find the z-score
- The rule the z-score is z = (x - μ)/σ , where
# x is the score
# μ is the mean
# σ is the standard deviation
* Lets solve the problem
- The average cost of a glass of iced tea is $1.25
- The standard deviation of it is 7 cents
- A new restaurant charges a price for iced tea that has a
z-value of -1.25
* Lets change the average cost to cent
∵ $1 = 100 cents
∴ The average cost of a glass of iced tea = 1.25 × 100 = 125 cents
∵ z = (x - μ)/σ
∵ z = -1.25
∵ μ = 125
∵ σ = 7
∴ -1.25 = (x - 125)/7 ⇒ multiply both sides by 7
∴ -8.75 = x - 125 ⇒ add 125 to both sides
∴ 116.25 = x
* The tea's actual cost is $116.25
