Answer: uses a visual representation of the logical flow of steps needed to reach a conclusion.

Step-by-step explanation:

A two column proof uses a visual representation of the logical flow of steps needed to reach a conclusion.

It is arranged into two columns named as "statement" and "reason" columns, where each statement must have valid logical and mathematical reason needed to reach the required conclusion..

The reasons in a two column proof are generally given details, vocabulary, definitions, postulates and previously proved theorems.

Hence, the correct statement is "uses a visual representation of the logical flow of steps needed to reach a conclusion."

A toy maker claims his best product has an average lifespan of exactly 14 years. A skeptical quality control specialist asks for

slamgirl [31]

Answer:

interval = [17.3948 , 20.6052]

Step-by-step explanation:

given,

random sample (n) = 45

average product lifespan = 19 years

standard deviation = 4 years

confidence interval of 99 % = ?

we know,

t* = qt(1.99/2 + 44 ) = qt(0.995,44)

t* = 2.692

so,

interval

$x = 19 \pm t* \times (\dfrac{s}{\sqrt{n}})$

$x = 19 \pm 2.692 \times (\dfrac{4}{\sqrt{45}})$

$x = 19 \pm 2.692 \times 0.5963$

$x = 19 \pm 1.6052$

interval = [19 - 1.6052 , 19 + 1.6052]

interval = [17.3948 , 20.6052]

Thanks for the help

The answer is B.

In the question it says "the intercept of 6" which means the equation has to have +6 in the answer, and there is only one answer choice containing that.
