I need help finding the answer to this question on edge.

Aliun [14]

Answer:

Step-by-step explanation:

We need to evaluate :-

$\rm\implies \displaystyle\rm\sum^4_n (-1)^n (3n + 2 )$

Here the $\Sigma$ is the sum operator . And here we need to find the sum from n = 1 to n = 4 . We can write it as ,

$\rm\implies (-1)^1 ( 3*1 +2) + (-1)^2 ( 3*2+2) + (-1)^3(3*3+2) + (-1)^4(3*4+2)$

Now we know that for odd powers of -1 , we get -1 and for even powers we get 1 . Therefore ,

$\rm\implies -1 ( 3 + 2 ) + 1 (6+2)+-1(9+2)+1(12+2)$

Now add the terms inside the brackets and then multiply it with the number outside the bracket . We will get ,

$\rm\implies -1 * 5 + 1 * 8 + -1*11 + 1*14 \\\\\rm\implies -5 + 8 - 11 + 14 \\\\\rm\implies\boxed{\quad 6 \quad}$

Hence the required answer is 6.

Part of a regression output is provided below. Some of the information has been omitted.

quester [9]

Answer:

301.189

Step-by-step explanation:

Given the table :

Source of Variation - - SS - - - df - - - MS - - - - F

Regression - - - - - -3177.17 - - -2 - - 1588.6

Residual - - - - - - - - ______ --17 - - -17.717

Total - - - - - - - - - - 3478.36 - - 19

Calculate the SSR, Sum of Square residual

The Sum of Square RESIDUAL (SSR), Mean Square Residual (MSR) and Degree of Freedom RESIDUAL (DFR) are related by the formular :

MSR = SSR / DFR

Hence,

SSR = MSR × DFR

Fr the table ;

MSR = 17.717 ; DFR = 17

SSR = (17.717 × 17)

SSR = 301.189

What is the ratio 42 inches to 9 feet as a fraction in simplest form?

murzikaleks [220]

6 goes into both 42 and 108 (9x12 so you are working with equal measurements) and you get 7/18
