Probability is the ratio of: the number of observations of an event n(A) compared to the total number of observation n(S). Generally it could be written as
P(A) =
Use combination to solve this problemThe event being observed n(A) in this problem is 2 engineers being selected from 4 engineers. The observation n(S) is about 2 people being selected from 10 people (engineers + pilots).
n(A) could be determined using combination of 2 engineers from 4 engineers
n(A) =
n(A) =
n(A) =
n(A) =
n(A) =
n(A) = 6
n(S) could be determined using combination of 2 people from 10 people
n(S) =
n(S) =
n(S) =
n(S) =
n(S) =
n(S) =
n(S) = 45
The probability
P(A) =
P(A) =
P(A) =
The probability is 2/15
Answer: See you have to understand the problem and then solve it Answer is: 5g - 2/10
The standard form using integers is x + 3y = 0
<em><u>Solution:</u></em>
Given that we have to write the given equation in standard form
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
Let us convert the given equation to standard form
Given equation is:
Multiply the terms inside bracket with constant outside the bracket in right hand side of equation
Simplify the right hand side of equation
Move the 3 from R.H.S to L.H.S
Move the terms from R.H.S to L.H.S
Thus the standard form is found
Answer:
f^-1(x)= -x/3 +1/6
Step-by-step explanation:
So its negative x over 3, plus, 1 over 6
First, distribute the 100 to the (x-1) portion:
500 = 100x - 100
then, add 100 to both sides of your equation to get “x” alone on the right side:
500 + 100 = 100x - 100 + 100
600 = 100x
next, divide 100x by 100 and 600 by 100 to isolate a singular “x”:
600/100 = 100x/100
6 = x
therefore, x=6 is your solution
