Answer:
A) There is a strong relationship showing that as the number of days increases, the height of the plants increases.
Step-by-step explanation:
Because the correlation coefficient of 0.85 is very close to 1, there's going to be a strong, positive linear correlation between the two variables. Therefore, option A is correct.
Hey there!
This equation is in standard form, which is .
We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.
a = 3, b = 1, c = -5
Let's plug these values into the quadratic equation:
Multiply 4(3)(-5) together and multiply 2(3). Square 1.
Add 1 and 60.
This is our answer in exact form. If you need this as an approximate value, let me know and I will do that for you.
Hope this helps!
Given:
The given polynomial is
When it divided by (x+1) gives remainder 0 and when divided by (x-2) gives remainder of 45.
To find:
The values of m and n.
Solution:
According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).
Let the given polynomial be P(x).
When it divided by (x+1) gives remainder 0. So, P(-1)=0.
...(i)
When P(x) is divided by (x-2) gives remainder of 45. So, P(2)=0
...(ii)
Multiply 2 on both sides of (i).
...(iii)
Subtract (iii) from (ii).
Putting m=5.5 in (i), we get
Therefore, the values of m and n are 5.5 and -21.5 respectively.
