The Food and Drug Administration advises people against eating fish with mercury concentrations exceeding 1 part per million (ppm). Researchers wonder if the average mercury content of large-mouth bass in a certain state exceeds the limits and, thus, make such fish inedible. They randomly sample largemouth bass from randomly selected lakes in this state and record the amount of mercury in each fish. What is the correct parameter in this example

Answers

Answer 1

Answer:

Answer:

The average amount of mercury in the population of large-mouth bass in this particular state

Step-by-step explanation:

Parameters are properties that describe entire populations rather than a sample. Therefore, since researchers are focused on the average mercury content of large-mouth bass, the correct parameter for the experiment would be the average amount of mercury in the population of large-mouth bass in this particular state.

========================================================

Explanation:

We're given the height in relation to base BC, so we need to find the length of this base. This is the same as finding the distance from B to C.

Turn to the distance formula

$d = \text{Distance from B to C}\n\nd = √((x_1-x_2)^2+(y_1-y^2)^2)\n\nd = √((-2-(-3))^2+(-1-(-2))^2)\n\nd = √((-2+3)^2+(-1+2)^2)\n\nd = √((1)^2+(1)^2)\n\nd = √(1+1)\n\nd = √(2)\n\n$

Coincidentally, the base and height are the same. This won't always be the case.

Now we can find the area of the triangle

$A = \text{Area of triangle}\n\nA = (1)/(2)*\text{Base}*\text{Height}\n\nA = (1)/(2)*√(2)*√(2)\n\nA = (1)/(2)*√(2*2)\n\nA = (1)/(2)*√(4)\n\nA = (1)/(2)*2\n\nA = 1\n\n$

The area of the triangle is 1 square unit.

The owner of a fabric store has determined that the profits P of the store are approximately given by P(x) = -x^2 + 70x+67, where x is the yards of fabric sold daily. Find the maximum profit to the nearest dollar. a) $617 b) $792 c) $1017 d) $1292 e) none

Answers

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Profit function of the store is given by

$P(x)=-x^2+70x+67$

We need to find the maximum profit.

For this, we first derivate the above function:

$P'(x)=-2x+70$

Now, put P(x) = 0, we get that

$-2x+70=0\n\n-2x=-70\n\nx=35$

Now, we will check that its maximality by finding the second derivative:

$P''(x)=-2<0$

it gives maximum profit at x = 35 yards.

And the maximum profit would be

$P(35)=-(35)^2+70* 35+67=\$1292$

Hence, Option 'd' is correct.
