Answer:
The probabily of P(not less than 6) is
P= the favorable outcomes/ the total outcomes
favorable out come is 1 case(7)
the total outcomes are 5 cases(2,3,5,6)
P=1/5=20%
Answer:
see the explanation
Step-by-step explanation:
Let
s ----> the number of students on the trip
t ----> the number of teachers on the trip
we have the equation
![s=25t](https://tex.z-dn.net/?f=s%3D25t)
This linear equation represent a proportional relationship, because the line passes through the origin
The constant of proportionality is equal to the slope of the line
so
![k=25\ \frac{students}{teacher}](https://tex.z-dn.net/?f=k%3D25%5C%20%5Cfrac%7Bstudents%7D%7Bteacher%7D)
That means -----> there are a ratio of 25 students by teacher in the trip
or
The number of students is 25 times the number of teachers in the trip
(5,465)(7,625)
slope(m) = (625 - 465) / (7 - 5) = 160/2 = 80
y = mx + b
slope(m) = 80
use either of ur points (5,465)...x = 5 and y = 465
now we sub and find b, the y int
465 = 80(5) + b
465 = 400 + b
465 - 400 = b
65 = b
equation is : y = 80x + 65...but we need it in standard form
y = 80x + 65
-80x + y = 65...multiply by -1 to make x positive
80x - y = -65 <== standard form
========================
function notation.....f(x) is the same as y
so y = 80x + 65 in function notation becomes f(x) = 80x + 65
=======================
x axis will be days rented
y axis will be total cost
to graph :
y = 80x + 65.....the slope here is 80...the y int is (0,65)
to find the x int, sub in 0 for y and solve for x
0 = 80x + 65
-80x = 65
x = - 65/80 = - 13/16....so ur x int is (-13/16,0)
and if u need to find more points on ur line....
80x - y = -65....sub in any number for x, and solve for y
Hello!
As you can see this line is horizontal. It is 6 units long. Therefore the center is three units in. Therefore the center of this circle is at (1,2).
I hope this helps!
