Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.

The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.

Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.

Answer:

x = 6

Step-by-step explanation:

The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64 = 36

b = ±[tex]\sqrt{36}[/tex]

b = ± 6

But we know that distance is always positive, so

b = 6

I have used b in place of x if you are confused about the variable usage.

Step-by-step explanation:

Depends on what kind of rotation you would be doing. But for example, if you are rotating 90 degrees about a point on a graph, your point (x, y) changes to (-y, x). Then another 90 degrees would be (-x, -y).

Answer:

37.5

Step-by-step explanation:

150/400*100 is the percentage

Answer:

37.5

Step-by-step explanation:

150/400 is .375 * 100 = 37.5

use this formula N/B*100

number divided by base x 100

10% of 10% is 0.01 then 1% of 1% is also 0.01

the same number of the same number is also 0.01 at this point:

25% of 25% is 0.01.

Answer:

[tex]y=-\frac{1}{5}x+6[/tex]

Step-by-step explanation:

We have the following equation

y=mx+b

where m is the slope

and b is the y intercept

we know that the slope is  -1/5 (or -.2)

which means that so far our equation looks like this

y= -.2x+b

which means we need to solve for b

we know that when x= -5 y= 7 which means we can plug in those values and solve for b

we have

7= (-.2*-5)+b

7=1+b

b=6

which means our equation is as follows

y= -1/5x+6

Answer:

The annual profits will be 2187.5

Step-by-step explanation:

p(x) = 65x - 0.3x^2

I am guessing that the 2 was supposed to be a square.

Simply plug in the number of pies sold:

p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

Answer:

Step-by-step explanation:

Were there not several equations from which to choose?

The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}.  The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300.  Because the discriminant is negative, the quadratic has no real solutions.

The quadratic equation with no real solution is 25x²-10x+4 = 0

The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Given that, which of the equations have no real solution,

Considering the quadratic equation 25x²-10x+4 = 0

D = [tex]\sqrt{b^{2} -4ac}[/tex]

We know, when √D > 0, real roots

√D = 0, equal roots

√D < 0, imaginary roots

[tex]\sqrt{b^{2} -4ac}[/tex] =

[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]

Since, the discriminant is less than 0, therefore, its roots are imaginary.

Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

Actually Welcome to the Concept of the exponents and indices.

here, we should remember one thing that,

3 ^3 = 27 and 1/3^x = 3^-x

so we get as,

(3^-3)^4-x = (3^3)^2x-1

==> 3^-12+3x = 3^6x-3

since the base is same that is 3 , we equate their powers.

-12x+3=6x-3

==> 3+3 = 6x+12x

==> 6 = 18x

hence ===> x = 6/18 = 1/3

hence, x = 1/3

Answer:

10a - 30b + 40

Step-by-step explanation:

Multiply each term inside the ( ) by the 5 outside the ( ).

5 x 2a = 10a

5 x -6b = -30b

5 x 8 = 40

Add the terms together (don't forget that it's negative 30b)

10a + -30b + 40 = 10a - 30b + 40

Answer:

5, 10 and 11 feet.

Step-by-step explanation:

Let length of first side be x feet then

second side  = 2x feet

third side = 2x + 1 feet.

So we have the equation:

x + 2x + 2x + 1 = 26

5x + 1 = 26

5x = 25

x = 5 feet.

So first side = = 5 feet, second = 10 and third = 11 feet.

Answer:

The answer is 1 5/12 or 17/12.

Step-by-step explanation:

First we turn 5 2/3 into a Improper fraction.

5 2/3 = 17/3

Next we change 4 to 1/4 then multiply 1/4 by 17/3.

17/3 * 1/4 = 17/12

17/12 = 1 5/12

Hope this helps! :)

Answer:

17/12

5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12
