Answer: D. This variable is a discrete numerical variable that is ratio-scaled.
Step-by-step explanation:
A Discrete variables are variables which are countable in a finite amount of time. For example, you can count the amount of money in your bank wallet, but same can’t be said for the money you have deposited in eveyones bank account as this is infinite.
So the number of times an individual changes job in a five years period is a perfect example of a discrete numerical variable that is ratio scaled because it can be counted.
Answer:
(2x - 1)(2x + 1)(x - 7)
Step-by-step explanation:
We use grouping to factor.
Step 1: Group 1st 2 terms together and factor
4x³ - 28x²
4x²(x - 7)
Step 2: Group last 2 terms together and factor
-x + 7
-1(x - 7)
Step 3: Combine
(4x² - 1)(x - 7)
Step 4: Factor out quadratic
(2x - 1)(2x + 1)(x - 7)
Answer:
See below.
Step-by-step explanation:
The corners of the square are:
(-7, 6) which becomes (-6, 7)
(-2, 6) which becomes (-6, 2)
(-7, 1) which becomes (-1, 7)
(-2, 1) which becomes (-1, 2)
From the top left corner of the square, ABCD rotates to ACDB (clockwise), so Darla is correct.
The new square is in the same quadrant as the original, so quadrant 2.
Answer:
(-3, 3)
Step-by-step explanation:
Substitute for y:
x+6 = -2x -3
3x = -9 . . . . . . . add 2x -6 to both sides
x = -3 . . . . . . . . divide by 3
y = (-3) +6 = 3 . . substitute for x in the first equation
The solution is ...
(x, y) = (-3, 3)
Answer:
Here you go :)
Step-by-step explanation:
(2 1/3)(3 3/4)
= 7/3(3 3/4)
= 7/3(15/4)
= 35/4
= 8 3/4
