Hmm, y=1 is directix
means it opens up or down
we will be using
(x-h)²=4p(y-k) where (h,k) is vertex and p is the distnace from focus to vertex and from vertex to direcitx
focus is (-1,-3)
find distance between y values because directix is a y value
midpoint is the vertex
from -3 to 1 is 2 units
since focus is below directix, it opens down, and p is negative
it is 2 units above focus
so at (-1,-1)
and p=-2
(x-(-1))²=4(-2)(y-(-1))
(x+1)²=-8(y+1) is da equation
Answer:
Yes, they do
Step-by-step explanation:
Yes, y = 3x represents direct variation. The fact that the line (graph) of y = 3x goes through the origin (0,0) reinforces this statement.
Answer:
Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8.

Answer:
Option a. 1.2 is the correct answer
Step-by-step explanation:
Given the data in the question;
sample size n = 10
sub group = 6
The average of sample means x" = 3.2
Average range value R' = 0.6
the value of UCL for the R-chart = ?
To get the value of UCL for the R-chart, we say;
= D₄ × R'
from table of constants "Tabular values for x-bar and range charts
for size 6, the factor for control limits for range D₄ = 2.004
so we substitute
= 2.004 × 0.6
= 1.2024 ≈ 1.2
Hence, Option a. 1.2 is the correct answer.
