Answer:
y=x-5
Step-by-step explanation:
the slope is one
So to find the y intersect you need to plug in the numbers given, like this:
-2=3 + b
subtract the three
-5=b
the y intercept is -5
y=x-5
Answer:
option c: angle 3 and angle 5
Step-by-step explanation:
Answer:
the difference is 150 but them total is 950
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
Answer:
The percentage of inter-rater reliability is 80%.
Step-by-step explanation:
The rate of inter-rater reliability is the division of the number of intervals in which they agreed number of total intervals.
In this problem, we have that:
There are 10 intervals.
The observers agreed on 8 of them.
So the rate of agreement is 8/10 = 0.8.
As a percentage, we multiply the rate by 100, so 0.8*100 = 80%.
The percentage of inter-rater reliability is 80%.
