Below is the solution:
<span>E(X) = 50*1 - 3*8000/10000
E(X) = 50 - 24 = $26 per year</span>
Answer:
$104.51
Step-by-step explanation:
No.of people = 7
How much each person paid = $14.93
How much is the total bill = $14.93 x 7
= $104.51

Answer:
I believe it's 60 legs.
Step-by-step explanation:
Each farmer has 2 legs so 2x6=12
Each cat has 4 legs so 4x6=24
Each kitten has 4 legs so 4x6=24
When you add all the sums up, you get 60.
The number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).
<h3>What are the solutions of the equations?</h3>
The equations are given below.
y = x² + x − 2 ...1
y = – x + 1 ...2
From equations 1 and 2, we have
x² + x − 2 = – x + 1
x² + 2x − 3 = 0
Then the factor of the equation will be
x² + 3x – x − 3 = 0
(x + 3)(x – 1) = 0
x = 1, –3
Then the value of y will be
At x = 1, we have
y = -1 + 1
y = 0
At x = -3, we have
y = -(-3) + 1
y = 4
Then the number of the solutions of the equations are 2 that are (1, 0) and (-3, 4).
The graph is given below.
