Answer:
Tyler made an error on step 2
The correct answer should be -20x+33
Answer:
We cannot infer at the 10% significance level that the assumption of ski centers is wrong
Step-by-step explanation:
The null hypothesis for this question can be stated as
Null hypothesis H0: =4
Alternate hypothesis Ha:
The test is two tailed
Standard Deviation –
= 2
z=(4.84-4)/(2/sqrt(63))
=3.33
Z(0.1/2)=1.645 is less than Z =3.334
Hence, we will reject H0
Hence, the average growth skier ski’s four times a year is not true
Answer:
The required polynomial is
Step-by-step explanation:
Given : A polynomial equation of degree 3 such that two of its roots are 2 and an imaginary number.
To find : The equation of polynomial with degree 3.
Solution :
It is given that the equation has 3 roots one is 2 and othe is imaginary.
So, one root 2 = (x-2)
Let the other two roots are imaginary i, -i
⇒ (x-i),(x+i)
Therefore, the roots of the polynomial of degree 3
Now, we solve the roots to find the equation,
Therefore, the required polynomial is
The end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.
<h3>What is a function?</h3>
It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
For the end behavior:
As x → ∞ f(x) → 1/2
And x → -∞ f(x) → 1/2
Thus, the end behavior of the function f(x) describes the behavior of the function as x approaches the +∞ f(x) approaches to 1/2 and the x approaches the -∞ f(x) approaches to 1/2.
