A gray-scale digital camera with 1,000,000 pixels takes a picture (the picture is made of 1,000,000 parts and each part has a ce

rtain amount of gray). A histogram is made where the data is the amount of gray in each of these parts. The histogram looks bell-shaped with a mean of 125 gray levels and a standard deviation of 15. How many pixels are brighter than 163 gray levels? 5000 10,000 160,000 50,000

What ethical issues have been raised by the scientific community's commitment to ensuring that experimental treatments are not
e-lub [12.9K]

Answer:

They include;

1. Fewer chances of determining how effective the treatment plan would be.

2. Inability of every patient to access the experimental treatment.

3. Difficulties in making knowledgeable decisions on the treatment plan.

4. Determining that the experimental treatments are offered with the right motive.

Step-by-step explanation:

In medical treatment administration, it is standard practice that drugs undergo clinical trials on test animals before they are administered to patients. However, some sicknesses are without known drugs for treatment or may have drugs that are still undergoing experiments and trials. In such cases, patients may want to be treated with experimental drugs.

Ethical issues such as the above-listed can arise from this. The foremost of them all is the fact that the treatment might prove ineffective thus causing more problems to the patient.

Which are the roots of the equation 3m^2-5m+1=0
Svetradugi [14.3K]

Answer:

       -(-5) ± √13             5 ± √13

x = ----------------------- = ---------------

              2(3)                       6

Step-by-step explanation:

This is a quadratic equation, with coefficients 3, -5 and 1.

The discriminant, b² - 4ac, turns out to be (-5)² - 4(3)(1), or 25 - 12  =  13

Thus, the roots are:

       -(-5) ± √13             5 ± √13

x = ----------------------- = ---------------

              2(3)                       6

Nookie1986 [14]
The <u>correct answer</u> is:

<span>c) Each point in the data set is near the regression line. 

Explanation:

A best fit regression line is the line that most closely approximates the data.  This means that the line must be near most of, if not all, of the points of the data set.  

If this truly is the line of best fit, the points of the data will be near the line.</span>

Find the x-coordinate of the point on the graph of y=x^2 where the tangent line is parallel to the secant line that cuts the cur
jek_recluse [69]
First find the secant line. The slope of the secant line through (-1,1) (when x=-1) and (2,4) (when x=2) is the average rate of change of y=x^2 over the interval [-1,2]:

\text{slope}_{\text{secant}}=\dfrac{2^2-(-1)^2}{2-(-1)}=\dfrac33=1

The tangent line to y=x^2 will have a slope determined by the derivative:

y=x^2\implies y'=2x

Both the secant and tangent will have the same slope when 2x=1, or when x=\dfrac12.
