Answer:
3/50
Step-by-step explanation:
P( 1st ball is a black ball) = number of black balls/ total balls
= 2/10 = 1/5
We put the ball back so we still have the same number of balls
P( 2nd ball is a red ball) = number of red balls/ total balls
= 3/10
P (1st ball black, 2nd red) = P( 1st ball is a black ball)* P( 2nd ball is a red ball)
=1/5* 3/10
= 3/50
8 bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.
Answer:
The total change in the number of bushels she has for sale after 5 days is 83.125 bushels
Step-by-step explanation:
The given parameters are;
The initial number pf bushels the farmer has = 120 bushels
The amount of bushels of wheat the farmer sells each day = 16⁵/₈ = 16.625
The number of bushels sold after 5 days = 16.625 × 5 = 83.125 bushels
The total change in the number of bushels she has for sale after 5 days = The number of bushels sold after 5 days
The total change in the number of bushels she has for sale after 5 days = 83.125 bushels.

Expand the expression.
0.8a - 2b - 2(-0.3a) + b
Determine the sign.
0.8a - 2b - 2*0.3a + b
Multiply the monomials.
0.8a - 2b +0.6a + b
Combine like terms.
