Answer is 6 miles per day
Answer is equation 48 = (x)(5) + 18
Step by step
You can use y intercept equation
y = mx + b
y = 48 total miles
m = rate of miles unknown
x = 5 days
b = starting point of 18 miles already ridden
48 = (x) (5) + 18
48 = 5x + 18
Subtract 18 from both sides to isolate the variable
48 - 18 = 5x + 18 - 18
30 = 5x
Now divide both sides by 5 to solve for x
30/5 = 5/5 x
X = 6 miles per day
Check your work, substitute 6 for x in your equation
48 = (6) (5) + 18
48 = 30 + 18
48 = 48
Problem solved!!
Answer:
Option 1: 
Step-by-step explanation:
Find the slope of the perpendicular line by finding the negative reciprocal of the original slope. (Negative reciprocal = flip upside down and add a negative). So we get -4 for the perpendicular slope.
Next, we know the point (-2,6) is on the line, so we can get x=-2 and y=6.
Plug this into point-slope form: 
Answer:
x=6
y=4
Step-by-step explanation:
just find the number that will match or u could just plug in one of those number and find other number
Answer: X=1.5
Step-by-step explanation:
The equation when y is -16
-16=-8x-4
-12=-8x
12/8 is 1.5
Answer:
(5.4582 ; 6.8618)
Step-by-step explanation:
Given the data:
6 10 2 6 3 3 3 6 6 6 6 5 8 9 10 10 7 9 3 6 5 10 9 9 10 3 8 6 6 3 3 6 6 5 4 10 9 3 5 7 10 6 3 8 6 8 3 3 5 5
Sample mean, xbar = Σx / n
n = sample size = 50
ΣX = 308
xbar = 308 / 50 = 6.16
Using a Calculator :
The sample standard deviation, s = 2.469
Confidence interval = xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 95% ; df = 50 - 1 = 49
Tcritical = 2.010
Hence,
Margin of Error= 2.010 * (2.469/sqrt(50)) = 0.7018
Lower boundary : (6.16 - 0.7018) = 5.4582
Upper boundary : (6.16 + 0.7018) = 6.8618
(5.4582 ; 6.8618)
