<u>Answer:</u>

The factor of 12x squared minus 4x minus one is (6x + 1) and (2x – 1)

<u>Solution:</u>

Need to determine factors 12 x squared minus 4x minus one

This means that we need to factorize following expression

12 x^{2}-4 x-1

On splitting the middle term in such a way that sum of two split terms must be -4x and product of two split terms must be -12 x^{2} we get,

12 x^{2}-6 x+2 x-1

=> 6x(2x -1) + 1 (2x - 1 )

Combining the terms we get

=> (6x + 1) (2x – 1)  

Hence factors of  12 x^{2}-4 x-1 is (6x + 1) and (2x – 1)

Answer:

26

Step-by-step explanation:

I can  be wrong but i most likely sure it is correct because a triangle is 180 degrees you have to add 102 with 52 take that total and subtract it with 180 to find that angle is what you need to find the length. Again i am not sure but might be right.

Answer:

#2 is the closest to the actual roots.

Step-by-step explanation:

12x^{3} -65x^{2} +24x+10=0

\frac{2}{3} is not a root, but 0.68078 is.

The other roots are -0.24572 and 4.9816.  The closest option is #2.

Answer:

from the t-distribution table, at df = 7 and t = 2.23

Lies p-values [ 0.05 and 0.025 ]

Hence;

0.025 < p-value < 0.05

Step-by-step explanation:

Given that;

x^{bar} = 6.5 gpm

μ = 5 gpm

n = eight runs = 8

standard deviation σ = 1.9 gpm

Test statistics;

t = (x^{bar} - μ) / \frac{s}{\sqrt{n} }

we substitute

t = (6.5 - 5) / \frac{1.9}{\sqrt{8} }

t = 1.5 / 0.67175

t = 2.23

the degree of freedom df = n-1 = 8 - 1

df = 7

Now, from the t-distribution table, at df = 7 and t = 2.23

Lies p-values [ 0.05 and 0.025 ]

Hence;

0.025 < p-value < 0.05
