Answer:
D. Refrigerants
Explanation:
In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act .
The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants such as R-12 and R-134a. This ban became effective on the 1st of January, 1993.
Refrigerants refers to any chemical substance that undergoes a phase change (liquid and gas) so as to enable the cooling and freezing of materials. They are typically used in air conditioners, refrigerators, water dispensers, etc.
Answer:
Below is the required code:
Explanation:
SELECT Product_Finish AS "Desk Finish",
avg(Standard_Price) AS "Average Price"
FROM Product_T
WHERE "Average Price">200
ORDER BY "Average Price" DESC;
One computer part is the CPU, it’s a piece of hardware the last allows your computer to access and interact all the applications and programs. The first ever CPU chip was invented around 4 decades ago. The keyboard is another computer part and it allows the user to type letters and numbers. There are about 104 keys on a keyboard and there are different parts in it. Some of the parts include, control keys, function keys, navigation keys, numeric keypad, and so on. A mouse is another device used with the keyboard to position the cursor. It’s a hand held device that detects two-dimensional motion relative to a surface. This motion is typically translated Into the motion of a pointer on a display, which allows a smooth control of the graphical user. Memory is a device to store all of your information and saved data. The motherboard is the backbone that tied together the computers components at one spot.
The gear ratios would look like A:B=1:9 and C:D=1:32 if you are just needing the gear teeth ratio. Not a lot of information to go off of from the question though
Answer:
Consider the following code.
Explanation:
save the following code in read_and_interp.m
function X = read_and_interp(s)
[m, n] = size(s);
X = zeros(m, 1);
for i = 1:m
if(str2num(s(i, 2:5)) == 9999)
% compute value based on previous and next entries in s array
% s(i, 2:5) retrieves columns 2-5 in ith row
X(i,1) = (str2num(s(i-1 ,2:5)) + str2num(s(i+1,2:5)))/2;
else
X(i,1) = str2num(s(i,2:5));
end
end
end
======================
Now you can use teh function as shown below
s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ];
read_and_interp(s)
output
ans =
96.000
114.000
109.500
105.000
112.000
