What does it mean to say two variables are positively associated
Answer:
A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases.
Martin has 128 pencils that he is putting
into boxes. Each box holds 6 pencils. If he
puts all the pencils into boxes, how many
more pencils will he need to fill the last box
completely?
128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3
Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3
which of the following quotients is greater that 9 and less than 12.
a) 144/12
b) 250/20
c) 320/20
d) 81/9
please help me
Answer:
(D)
Step-by-step explanation:
Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)
Step-by-step explanation:
12 less ( subtracting 12 from something else)
the quotient-Dividing between two values
A number: let's use Y
so we want to substract 12 from the product of y/9
(Y/9) -12.
So 81 is greater than 9 but 9 is less than 12.

Given that f(x) = x^2– 5x– 36 and g(x) = x + 4, find (f +9)(x) and express
the result in standard form.
Answer:
x^2 -4x-32
Step-by-step explanation:
f(x) = x^2– 5x– 36
g(x) = x + 4
(f +g)(x) = x^2– 5x– 36 + x + 4
Combine like terms
= x^2 -4x-32
Answer:
[tex] \longmapsto \: f(x) = {x}^{2} - 5x - 36 \\ \longmapsto \: g(x) = x + 4 \\ \longmapsto(f + g)(x) \\ = f(x) + g(x) \\ = ( {x}^{2} - 5x - 36) + (x + 4) \\ = {x}^{2} - 5x - 36 + x + 4 \\ = \boxed{ {x}^{2} - 4x - 32}[/tex]

C. Again, assume that we can't produce more than 1,000 un necessarily some x value, let's call it C, for which the profit is exactly 0? Explain your answer. 2. For the following: A. Produce a function f(x) that satisfies the following conditions: 1. Its domain is all real numbers. 11. It has no maximum and no minimum on the interval (1, 3). III. It satisfies f(1) = 1 and f(3) = -1, but there does not exist a c between 1 and 3 such that f(x) = 0. B. Construct a function f(x) that satisfies the following conditions: C. fis continuous for all x.
Answer:
C. Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Line segment XY has endpoints X(5,7) and Y(-3,3)
y=-2x+7
Step-by-step explanation:
line segment xy has endpoints x(5 7) and y(-3 3)
for the equation of the perpendicular bisector of line segment xy
slope of line segment xy = 7-3 / 5+3
= 4/8
=1/2
so slope of perpendicular bisector is -2
as m1m2= -1 or m1= -1/m2
As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy
midpoint(x,y) = (5-3 / 2 , 7+3 / 2)
=(2/2, 10/2)
=(1,5)
find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2
y-5 = -2(x-1)
y-5 =-2x+2
y=-2x+7

Answer:
m∠1 = 52, m∠2 = 60
Step-by-step explanation:
68 and ∠2 are interior angles. 128 is exterior angle.
Formula : -
Sum of two interior angles = Exterior angle
68 + ∠2 = 128
∠2 = 128 - 68
∠2 = 60
∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,
∠1 + 128 = 180
∠1 = 180 - 128
∠1 = 52
