Answer:
(6, -3)
Step-by-step explanation:
I will solve this system using elimination.
[/tex]
I will multiply by 2 so that -x becomes -2x.
2(-x + 2y = -12)
Distribute.
-2x + 4y = -24
Now subtract this from the other equation.
2x + 3y = 3
<u>-2x + 4y = -24</u>
7y = -21
Divide both sides by 7.
y = -3
Now that we have the value of y, plug it into the original equation.
-x + 2(-3) = -12
Simplify.
-x - 6 = -12
Add 6 to both sides.
-x = -6
Divide both sides by -1.
x = 6
(6, -3)
Answer:
The answer is 3.6 acres per day
Step-by-step explanation:
To find the unit rate divide the number of acres by number of days
∴ Unit rate = ÷
= (6 × 4 + 3)/4 ÷ (1 × 8 + 7)/8 = 27/4 ÷ 15/8
= 27/4 × 8/15 = 18/5 = 3.6 acres per day
Here is your answer:
Therefore the answer is "65/88."
Hope this helps!

Answer:
The value is
Step-by-step explanation:
From the question we are told that
The parameters are α = 3, θ = 0.5
The cost of making a unit on the first day is c = $2
The selling price of a unit on the first day is s = $5
The selling price of a leftover unit on the second day is v = $ 1
Generally the profit of a unit on the first day is
The profit of a unit on the second day is
=>
Generally the probability of making profit greater than $ 1 is mathematically represented as
=>
Now from the gamma distribution table we have that
Generally the probability of making profit less than or equal to $ 1 is mathematically represented as
=>
=>
So the probability of making $3 is
and the probability of making -$1 is
Generally the value of profit per day is mathematically represented as
=>
=>
