Write an equation of the parabola with focus (0, -3) and vertex at the origin. Use z for the independent variable.
Answers
Answer:
z^2 = -12y
or y = -(z^2/12)
Step-by-step explanation:
Answer:
z^2 = -12y
Step-by-step explanation:
Given the vertex at origin;
This is same as (0,0)
The focus (0,-3)
The general form is;
(z-h)^2 = 4p(y-k)
(h,k) is the vertex (0,0); so h = 0 and k = 0
The focus is given as;
(h,k + p)
so ;
k + p = -3
but k =0
so p = -3
Thus, the equation of the parabola is;
(z-0)^2 = 4(-3)(y-0)
z^2 = -12y

NEED HELP QUICK!!!!! A set of data includes the point (17,3.8) and has the regression equation y=-25x+436. What is the residual for this point
Answers
Given:
The regression equation is:
[tex]y=-25x+436[/tex]
The given point is (17,3.8).
To find:
The residual for the given point.
Solution:
We have,
[tex]y=-25x+436[/tex]
Substituting [tex]x=17[/tex], we get
[tex]y=-25(17)+436[/tex]
[tex]y=-425+436[/tex]
[tex]y=11[/tex]
The predicted value at [tex]x=17[/tex] is 11.
The given point is (17,3.8). It means the observed value at [tex]x=17[/tex] is 3.8.
Formula for residual:
Residual = Observed value - Predicted value
Residual = [tex]3.8-11[/tex]
Residual = [tex]-7.2[/tex]
Therefore, the residual for the given point is -7.2.
Find the slope of each line.
Answers
Answer:
C) 1
Step-by-step explanation:
Slope = change in y over change in x
In the graph shown as y goes up 1 x goes up 1
so slope = 1/1 or 1
The slope equation is y=mx+b.
b is where the line crosses on the y axis, also known as the y-intercept.
m is the slope, which you are trying to find.
y and x are the points on the graph.
The slope is 3/3, which can be turned into 1, so the answer is c.
Angles in circle solve for each variable
Answers
Answer:
x degree = 112 degree
Step-by-step explanation:
let the intersecting point of two cords be O.
then arc QR = angle QOR
which means ; 68 degree = angle QOR
Now,
angle QOR + angle POQ = 180 degree ( linear pair )
or, 68 degree + angle POQ = 180 degree
hence, angle POQ = 112 degree,.
e) What does the value of the mean absolute deviation tell you about the spread of the data? (2 points)
Answers
Answer:
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. ... Step 2: Calculate how far away each data point is from the mean using positive distances.
Mean deviation is defined as how much is each element of the data is far away from the mean of the data.
What is mean in statistics?We can define the mean of the given data set as the average of all the numbers. Mathematically, we can write mean as -
M = ∑x{i}/n
Given is to discuss what does the value of mean absolute deviation tell about the spread of the data.
Mean deviation is defined as how much is each element of the data is far away from the mean of the data. Mathematically, we can write mean deviation as -
[tex]$\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|[/tex]
where -
m(X) = average or mean value(n) = number of data elements in the data setx(i) = data valuesTherefore, Mean deviation is defined as how much is each element of the data is far away from the mean of the data.

Find the value for a.
Answers
Answer:
a = 25
Step-by-step explanation:
The exterior angles of a polygon sum to 360°
Sum the exterior angles and equate to 360
a + a + 40 + 51 + 55 + 54 + 2a + 60 = 360, that is
4a + 260 = 360 ( subtract 260 from both sides )
4a = 100 ( divide both sides by 4 )
a = 25
