51 = x + (x + 31)
Solve that in order to find the answer to your problem.
Step-by-step explanation:
The expected value is the sum of each probability times the value.
E = 0.25 (10) + 0.75 (-5)
E = -1.25
The stock is expected to decrease by $1.25.
Answer with explanation:
The equation, y=3 x,
y=Distance traveled
x =Total time
![\frac{\text{Distance traveled}}{\text{Time}}=\frac{y}{x}=3\\\\ \frac{dy}{dx}={\text{Rate of change}}={\text{Velocity}}=3 {\text{unit of time}]](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BDistance%20traveled%7D%7D%7B%5Ctext%7BTime%7D%7D%3D%5Cfrac%7By%7D%7Bx%7D%3D3%5C%5C%5C%5C%20%5Cfrac%7Bdy%7D%7Bdx%7D%3D%7B%5Ctext%7BRate%20of%20change%7D%7D%3D%7B%5Ctext%7BVelocity%7D%7D%3D3%20%7B%5Ctext%7Bunit%20of%20time%7D%5D)
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit ,and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
Simple, you are adding a negative to a positive, so think of it as a subtraction, 5/6 - 2/3 = .
2/3 is 4/6.
5/6 - 4/6 = 1/6
Let us assume the common ratio = x
Then from the given question we can write
7x + 2x = 450
9x = 450
x = 450/9
= 50
Then the quantity 450 grams can be divided in the ratio of 7 : 2 by = 7x:2x
= (7 * 50) : (2 * 50)
= 350:100
I hope this is the answer you were looking for and the procedure for finding the answer is also absolutely clear to you.
