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.

A line passes through points (8, – 7) and has a slope of -5/4.The equation in Ax+By=C form for this line will be 5/4x + y = 3

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that, A line passes through the point (8, – 7) and has a slope of -5/4.

First, convert the slope and the given point to point-slope form:

y+7 = -5/4 (x-8)

Simplify for y to get the slope-intercept form:

y+7 = -5/4x + 10

y = -5/4x + 3

The equation in Ax+By=C form for this line is,

5/4x + y = 3

Thus, a line passes through points (8, – 7) and has a slope of -5/4.The equation in Ax+By=C form for this line will be 5/4x + y = 3

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

Answer:

-8/5

Step-by-step explanation:

Slope is calculated as the change in y over the change in x, or the rise over the run.

Two points on this line are (2, -4) and (3, 4) The rise between these two points is 8, and the run between these two points is -5.

Therefore,  the slope is just 8/-5,  or -8/5.

Let  me know if this helps!

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.

n = -40/9

Step-by-step explanation:

Let n = the number

(1/2)n - 2/3 = (1/5)n - 2

Multiply both sides by 30, which will get rid of the fractions.

15n  - 20 = 6n - 60
