This can be solved by Newton's binomial formula
Tk+1 = (n k) a∧(n-k) b∧k k+1=7 => k=6, n=11 , a=-3x and b=-2y
T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6
T7= 462 (-3x)∧5 (-2y)∧6
The correct answer is A.
Good luck!!!
Y = x^2 - 16x + 17
-16/2 = (-8)
(-8)^2 = 64
Add 64 and subtract 64
y = x^2 - 16x + 64 + 17 - 64
y = (x - 8)^2 - 47
Answer:
c. Car color (e.g. red, blue, grey)
Step-by-step explanation:
There are four level of measurements: Ordinal, Nominal, Interval and Ratio.
- Ordinal variables are categorical variables and have a ordered categories. For example,the health of patients: Excellent, Good, Average and Poor.
- Nominal variables are also categorical variables but they do not have a ordered category or any numerical value. For example, Gender: Male or Female, or Occupation:, Accountant, Clerk, Manager.
- Interval variable are variables that take numerical values. These variables are ordered and the difference between two values is meaningful. For example, temperature in degrees F.
- Ratio variable are type of interval variables but they do not have a variables with a 0 measurement. For example, height, age, money.
Considering all the option:
(a) Age (in years) is an interval variable.
(b) Age grouped as < 18, 18 - 29, 30-59, 60 > are basically ordered categorical variables. Thus, they are ordinal variables.
(c) Car Color (red, blue, grey) are nominal variable because they are not ordered and cannot be measured.
(d) Letter grade in a course (A+, A, A-, B+, B) are also ordinal variables because they are ordered and represent the performance quality of the student.
Thus, the correct answer is (c).
Answer:
Step-by-step explanation:
assuming your rewriting it in slope-intercept form
-6x + 3y = -18 slope-intercept form is y = mx + b so we must get it in that format
first we divide the 3 from 3y but whatever we do to that we must so to all so -6x and -18 are also going to be divided by 3 and you will get
-2x + y = -6 after dividing everything by 3
now you want to add 2x to the left side to cancel out that -2x but whatever you do to one side you must do to the other so its going to be
y = 2x - 6
This should be your answer hope this helps
y = 2x - 6
