Your answer should be 23/80
Where is this so called table, its helpful with the question
Answer:
6 fingers
Step-by-step explanation:
Let X = the base of the numbers above
If X > 0
Then we have:
325 = 3 * X² + 2 * X¹ + 5 * X°
325 = 3X² + 2X + 5
42 = 4*X¹ + 2*X°
42 = 4X+ 2
And
411 = 4*X²+ 1*X¹ 1*X°
42 = 4X² + X + 1
Since 325 + 42= 11 then
3X² + 2X + 5 + 4X+ 2 = 4X² + X + 1 ------ Collect Like Terms
3X² - 4X² + 2X + 4X - X + 5 + 2 - 1 = 0
-X² + 5X + 6 = 0 ------- Multiply both sides by -1
X² - 5X - 6 = 0 ------- Factorise the Equation
X² - 6X + X - 6 = 0
X(X - 6) + 1( X - 6) = 0
(X + 1)(X - 6) = 0
X + 1 = 0 or X - 6 = 0
X = -1 or X = 6
But X>0
So, X =-1 is invalid
X = 6
The expected number of fingers of the Martian is 6
Use a(b-c) = ab - ac
5(x-3) + 2x = 41
5x - 15 + 2x = 41
7x - 15 = 41
7x = 56
x = 8
Answer:
It can not be modeled by a linear function
Step-by-step explanation:
The given parameters can be represented as:
Where: x = rounds and y = players
Required:
Determine if it can be represented by a linear function
To do this, we simply calculate the slope (m)
and
Using: , we have:
Using , we have:
<em>Since both slopes are not the same, the relationship be modeled by a linear function</em>
