15. What is the rule for an arithmetic sequence whose first term is 12 and the common
difference is 9?
Answer:
T1=12 a=12 a=T1
d=9
your Arithmetic equation is Tn=a+(n-1)d
Tn=a+(n-1)d
SUBSTITUTE a and d in your equation
Tn=12+(n-1)(9)
Tn=12+9n-9
Tn=3+9n or Tn=9n+3

Answer:it’s B (120 succes and 80 failures for khan academy)
Step-by-step explanation: trust me
The shape of the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal because the number of success in district A is 120
How to determine the shape of the distribution?The given parameters are:
Proportion of adults in district A = 60%Proportion of adults in district B = 45%Sample size of A, n = 200Sample size of B, n = 100In the sample size of 200, the number of adults that support a new ballot measure is:
Success = 60% * 200
Success = 120
Those that oppose is
Failure = 200 - 120
Failure = 80
If 45% supports a new ballot measure in district B, then 55% do not support
The difference between those that support and do not support is:
(55% - 45%) * 100 = 10
Hence, the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal

PLEASE HELP !!!!!!!! What is the equation of the directrix for the following parabola: -8(x-5)=(y+1)^2
a. y=-3
b. x=7
c. y=7
d. x=-3
Answer:
x=7
Step-by-step explanation:
The directrix of the equation is x=7
What is directrix of parabola?The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.
The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.Given:
-8(x-5)=(y+1)²
Now, using the definition of directrix
x= 8/4 +5
x= 2+ 5
x= 7
