Hey there!!
Given equation :
11x² + 35x + 6
Now let's write 35x as 33x and 2x
Then the equation would become :
... 11x² + 33x + 2x + 6
... Now, let's take the common terms 11x² + 33x and 2x + 6
It would become :
... 11x ( x + 3 ) + 2 ( x + 3 )
... Now, we will write this as :
... ( 11x + 2 ) ( x + 3 )
Hence, this is as the answer...
Hope my answer helps!!
Answer:
−35.713332 ; 0.313332
Step-by-step explanation:
Given that:
Sample size, n1 = 11
Sample mean, x1 = 79
Standard deviation, s1 = 18.25
Sample size, n2 = 18
Sample mean, x2 = 96.70
Standard deviation, s2 = 20.25
df = n1 + n2 - 2 ; 11 + 18 - 2 = 27
Tcritical = T0.01, 27 = 2.473
S = sqrt[(s1²/n1) + (s2²/n2)]
S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]
S = 7.284
(μ1 - μ2) = (x1 - x2) ± Tcritical * S
(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284
(μ1 - μ2) = - 17.7 ± 18.013332
-17.7 - 18.013332 ; - 17.7 + 18.013332
−35.713332 ; 0.313332
