The FDA recommends that women who are pregnant avoid eating more than three 6.00 oz servings of bluefish per month because of th

kirza4 [7]

Answer:

5,562 x $10^{-6}$

Step-by-step explanation:

Firts, we need to find the maximum recommended amount of bluefish per month. Since the FDA recommends <em>3 servings of 6.00 oz each</em>, the maximum amount would be:

the maximum amount of bluefish per month = $3 * 6.00 oz = 18.00 oz$

Since bluefish contains <em>0.309 ppm of mercury per 1x $10^{6}$ oz of fis</em>h, then:

0.309 oz mercury --------> 1x $10^{6}$ oz of fish

How many ( $y$ ) --------> 18.00 oz of fish

$y = \frac{18.00 oz of fish * 0.309 oz of mercury}{1 x 10^{6} oz of fish } = 0.000005562 = 5.562 x 10^{-6}$ oz mercury

Find the area of the triangle defined by the coordinates (7, 1), (0, 10), and (9, 4). (To the nearest tenth)

slega [8]

Answer:

C) 19.5 square units

Step-by-step explanation:

The area from coordinates can be computed as ...

A = (1/2)|x1(y2 -y3) +x2(y3 -y1) +x3(y1 -y2)|

= (1/2)|7(10 -4) +0(4 -1) +9(1-10)| = (1/2)|7·6 +9·(-9)|

= (1/2)|-39| = 39/2 = 19.5

The area of the triangle is 19.5 square units.

Paul predicts that n stalks of corn planted together will produce (2n2–2n)(2n2–2n) ears of corn. If Paul plants three corn plant

Free_Kalibri [48]

Given that the production of n stalks of corn planted has been modeled by (2n^2-2n), then the approximate ears of corn produced by 3 stalks will be given by:
2n^2-2n
plugging in n=3 in the formula we get:
2(3)^2-2(3)
simplifying we get:
2(9)-6
=18-6
=12
the answer is: 12 ears

The National Center for Educational Statistics surveyed 5400 college graduates about the lengths of time required to earn their

fenix001 [56]

Answer:

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.9}{2} = 0.05$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.05 = 0.95$ , so $z = 1.645$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.645*\frac{1.9}{\sqrt{4500}} = 0.04$

The lower end of the interval is the sample mean subtracted by M. So it is 5.4 - 0.04 = 5.36 years.

The upper end of the interval is the sample mean added to M. So it is 5.4 + 0.04 = 5.44 years.

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
