Answer:
Periodic
Step-by-step explanation:
Because the terms repeat, this is a periodic sequence.
Answer:
See explanation
Step-by-step explanation:
Let c be the number of cows and d be the number of ducks.
c cows have 4c feet, d ducks have 2d feet. In total, c cows and d ducks have
4c + 2d = 148 feet.
Divide it by 2:
2c + d = 74.
This gives us that the number of ducks is even and cannot be 0 (because farmer Brwn has ducks). The minimum possible number of ducks is 2, so the maximum possible number of cows is 36.

Answer:
x=7 multiplicity of 2
Step-by-step explanation:
14x - 49 = x^2
Subtract x^2 from each side
-x^2 +14x - 49 = x^2-x^2
-x^2 +14x - 49 = 0
Multiply by -1
x^2 -14x +49 =0
What 2 numbers multiply together to give you 49 and add together to give you -14
7*-7 = 49
-7+-7 = -14
(x-7) (x-7) = 0
Using the zero product property
x-7 = 0 x-7 =0
x-7+7= 0+7 x-7+7 =0+7
x =7 x=7
Answer: a. −0.41
Step-by-step explanation:
The slope for the best-fitting linear equation is given by :-
![b=\dfrac{SS_{xy}}{SS_x}](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7BSS_%7Bxy%7D%7D%7BSS_x%7D)
where ,
=sum of squared deviations from the mean of X.
= correlation between y and x in terms of the corrected sum of products.
As per given , we have
![SS_{xy}=-16.32](https://tex.z-dn.net/?f=SS_%7Bxy%7D%3D-16.32)
Then, the value of the slope for the best-fitting linear equation will be
![b=\dfrac{-16.32}{40.00}=-0.408\approx -0.41](https://tex.z-dn.net/?f=b%3D%5Cdfrac%7B-16.32%7D%7B40.00%7D%3D-0.408%5Capprox%20-0.41)
Hence, the value of the slope for the best-fitting linear equation= -0.41
So the correct answer is a. −0.41 .
