Answer:
1) Cubic
2) 2
3) -3
4)
5)
Step-by-step explanation:
The given polynomial is:
The degree i.e. the highest exponent of the variable involved is 3. So the polynomial is a Cubic polynomial.
The terms in a polynomial can be distinguished by addition and subtraction symbols. So, for the given polynomial there are 2 terms.
The constant term is the term without any variable. So the constant term in given polynomial is -3.
Leading term is the term with variable having highest exponet which defines the degree of the polynomial. So leading term of the given polynomial is
Leading coefficient is the coefficient of the leading term. So for given polynomial the leading coefficient would be

Answer:
Having brown hair and having freckles are not necessarily independent events
Step-by-step explanation:
We are given the following information in the question:
Percentage of children having brown hairs = 46%
Percentage of people children having freckles = 25%
But it cannot be concluded that
German children of Caucasian descent are brown‑haired with freckles =
This is not always true because of the following reasons:
Brown hair and having freckles are not necessarily independent events.
We can not assume that event of a child having brown hair is independent of the event of child having freckles. The events could be dependent as well.
The above will only be true when event of a child having brown hair is independent of the event of child having freckles.
If the events are independent then,
Answer:
So the Point of intersection is (-4,-2)
Which is option A
Step-by-step explanation:
The given system of equations is
-0.1x - 0.8y = 2 ...................(i)
0.6x - 0.5y = -1.4 ...................(ii)
Let us take equation (i) and use method of substitution for solving it
the equation (i) is
-0.1 x - 0.8y = 2
Adding 0.8y on both sides
-0.1 x + 0.8 y - 0.8 y = 2 + 0.8 y
-0.1 x = 2 + 0.8 y
Dividing both sides -0.1
x = -8 y - 20 ..........................(iii)
Now we will use this value and put it into equation (ii) to find the value of y
Equation (ii) is
0.6 x - 0.5 y = -1.4
Put value of x
0.6(-8 y - 20) - 0.5 y =-1.4
It becomes
-4.8 y - 12 - 0.5 y = -1.4
adding 12 on both sides
-4.8 y - 0.5 y - 12 + 12 = -1.4 + 12
it becomes by solving
-5.3 y = 10.6
Dividing both sides by -5.3
So
y = -2
Now we have the value of y putting it in equation (iii)
Equation (iii) is
x = -8 y - 20
Putting value of y
x = -8*(-2) - 20
x = 16-20
x=-4
So the Point of intersection is (-4,-2)
