Answer: D) (x + 1))x + 2)(x - 3)

Step-by-step explanation:

The x-intercepts help us to form the equation of the curve:

(-2, 0) (-1, 0) and (3, 0)

--> x = -2, x = -1, x = 3

--> x + 2 = 0 x + 1 = 0 x - 3 = 0

--> (x + 2) × (x + 1) × (x - 3) = 0

This is the reverse order for the Zero Product Property

What number can you add to <img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B7%7D%20" id="TexFormula1" title=" \sqrt{7} " alt="

Question says about what number can you add to

$\sqrt{7}$ to get a rational number.

We know that rational numbers are the numbers which are written in form of p/q where p and q both are integers.

but q can never be 0.

If we add only some integer or real number to $\sqrt{7}$ then we will still get irrational number which is not of the form p/q.

so the only way to finish the radical part is to use the opposite of that $\sqrt{7}$ which is - $\sqrt{7}$

As you can see that

$\sqrt{7}$ - $\sqrt{7}$ = 0

and we know that 0 is a rational number because that can be written as 0/1 in p/q form.

Hence final answer is - $\sqrt{7}$

Data were collected on random specimens of Yellowfin tuna from 1991 and 2010. For the sample of 231 specimens of Yellowfin tuna,

Molodets [167]

Answer:

95% confidence interval: (0.325 ,0.383)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 231

Sample mean = 0.354 ppm

Sample standard deviation = 0.231 ppm

95% confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 4 and}~\alpha_{0.01} = \pm 1.97$

$0.354 \pm 1.97(\dfrac{0.231}{\sqrt{231}} ) = 0.354 \pm 0.029 = (0.325 ,0.383)$
