A tank contains 300 liters of fluid in which 40 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pu

bonufazy [111]

Answer:

A(t) = 300 -260e^(-t/50)

Step-by-step explanation:

The rate of change of A(t) is ...

A'(t) = 6 -6/300·A(t)

Rewriting, we have ...

A'(t) +(1/50)A(t) = 6

This has solution ...

A(t) = p + qe^-(t/50)

We need to find the values of p and q. Using the differential equation, we ahve ...

A'(t) = -q/50e^-(t/50) = 6 - (p +qe^-(t/50))/50

0 = 6 -p/50

p = 300

From the initial condition, ...

A(0) = 300 +q = 40

q = -260

So, the complete solution is ...

A(t) = 300 -260e^(-t/50)

___

The salt in the tank increases in exponentially decaying fashion from 40 grams to 300 grams with a time constant of 50 minutes.

Of 560 samples of seafood purchased from various kinds of food stores in different regions of a country and genetically compared

frutty [35]

Answer:

a) (0.5256,0.5944)

c) Criticism is invalid

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 560

Proportion of mislabeled = 56%

$\hat{p} = 0.56$

a) 90% Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.64$

Putting the values, we get:

$0.56\pm 1.64(\sqrt{\dfrac{0.56(1-0.56)}{560}}) = 0.56\pm 0.0344\\\\=(0.5256,0.5944)$

b) Interpretation of confidence interval:

We are 90% confident that the true proportion of all seafood in the country that is mislabeled or misidentified is between 0.5256 and 0.5944 that is 52.56% and 59.44%.

c) Validity of criticism

Conditions for validity:

$np > 10\\n(1-p)>10$

Verification:

$560\times 0.56 = 313.6>10\\560(1-0.56) = 246.4>10$

Both the conditions are satisfied. This, the criticism is invalid.

Helppppp meeee plzzzzz

Answer:

Angle B is 41 degrees

Step-by-step explanation:

1) find the supplement of the 113 degree angle; it is 180-113, or 67, degrees.

2) recognizing that the sum of the interior angles of a triangle is 180 degrees, add up 67 and 72 degrees, obtaining 139 degrees, and subtract this sum from 180 degrees:

180 degrees - 139 degrees = 41 degrees (answer)

The steps are outlined above; the end result is that <B is 41 degrees.

1/8(p+24)=9<br> Distributive property

Grace [21]

Hey there!

1/8(p + 24) = 9

1/8(p) + 1/8(24) = 9

1/8p + 3 = 9

SUBTRACT 3 to BOTH SIDES

1/8p + 3 - 3 = 9 - 3

CANCEL out: 3 - 3 because it gives 0

KEEP: 9 - 3 because it help solve for the p-value.

NEW EQUATION: 1/8p = 9 - 3
SIMPLIFY IT!

1/8p = 6

MULTIPLY 8 to BOTH SIDES

1/8p * 8 = 6 * 8

CANCEL out: 1/8 * 8 because it gives 1

KEEP: 6 * 8 because it gives the p-value.

NEW EQUATION: p = 6 * 8

SIMPLIFY IT!

p = 48

Therefore, your answer is: p = 48

Good luck on your assignment & enjoy your day!
