Slope = rise over run = the change in y over the change of x
if you want it to be exactly 2, then you have to make sure the equations are proportional.
-5 - y / 6-1
so you simplify it -5-y/ 5
the answer needs to be 2 times 5,
2 x 5 = 10, so you need to add 5 because that's what you subtract from it in the end.
y = 15
Answer:
Step-by-step explanation:
Given that there are 3 boxes. First box contains 100 components of which 20 % are defective, second box contains 200 components of which 25 % are defective, third box contains 300 components of which 40 % are defective.
Box is selected randomly and from this box one component is selected randomly. The chosen component turned out to be defective.
Here A1, A2 and A3 events from drawing I, II and III box are mutually exclusive and exhaustive
B = The drawn ball is defective
Required probability
a) second box = P(A2/B)
=
(by Bayes theorem of conditional probability)
= 
b) third box = P(A3/B)
=

Step-by-step explanation:
Unit digit=y
tens digit=x
the number: 10x+y
We suggest this system of equations:
x+y=7
(10y+x)=(10x+y)+9
we solve it by substitution method.
x=7-y
10y+(7-y)=(10(7-y)+y)+9
9y+7=70-10y+y+9
9y+10y-y=70+9-7
18y=72
y=72/18=4
x=7-y
x=7-4=3
number=10x+y=10*3+4=30+4=34
solution: the number: 34
To check:
3+4=7
43=34+9
