Mila [183]

Answer:

If a mother is smoking and there are significant birth weights, a bar graph will be most effective. A bar graph can show how many children have similar weights, and you can tell which weights are most common.

Hope this helped.

In casting experiments performed using a certain alloy.
jeyben [28]
Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds

The Cancer Conference (Tumor Board) qualifies as a ............................. and therefore can share some PHI with other phy
Anna71 [15]

The reason why the Cancer Conference (Tumor Board) can share some PHI with other physicians is that it is a not covered entity.

<h3 /><h3>What is a not covered entity?</h3>

These are entities that are not subject to the Health Insurance Portability and Accountability Act (HIPAA) rules which include those of privacy.

As a result, they can share PHI with other physicians to get better insight on conditions affecting their patients.

a) using your equation from step 2d, estimate the gpa of a student who studies for 15 hours a week. justify your answer.
Pavlova-9 [17]

Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1

<h3>How to predict an equation?</h3>

The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.

Now, the equation of best fit is given as;

y = 0.149x + 0.89

Thus, if the number of study hours of interest is 15, then the GPA is;

GPA =  0.149(15) + 0.89

GPA = 3.1
