Answer: 2 and 1/4
Step-by-step explanation: To solve this problem, first remember that dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.
÷ 
→ x 
= 36/16 = 9/4
The fraction 9/4 can be written as the mixed number 2 and 1/4.
BD=10 because it is symmetrical to AD.

Answer:
2x -3y = 21
Step-by-step explanation:
The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.
3x +2y = 6 . . . . . given equation
2x -3y = c . . . . . . coefficients swapped, one negated
2(6) -3(-3) = c = 21 . . . . . the value of c for the given point
The desired equation is ...
2x -3y = 21
Answer:
a) 2.188
b) John's rent is not an outlier
c) His rent has to be higher than $1,235 to be an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard University is $780 with a standard deviation of $208.
(a) John’s rent is $1,235. What is his standardized z-score?
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $1235
μ is the population mean = $780
σ is the population standard deviation = $208
Hence,
z = 1235 - 780/208
z = 2.1875
Approximately to 3 decimal place = 2.188
(b) Is John’s rent an outlier?
No it isn't
(c) How high would the rent have to be to qualify as an outlier?
John’s rent would have to be higher than $1235
