Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term
, is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... (
)
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation.
is pretty close to 3.14.
160
3.14 = 502.4, which is decently close to our other answer.
Hope this helps!

The solutions of the equations are x = 1 and y = 2
The system of equations are
4x + 3y = 10
-4x + 5y = 6
Here we have to use the elimination method. Eliminate the x term and find the value of y term
Add both equation
3y + 5y = 10 +6
Add the like terms
8y = 16
y = 16 / 8
Divide the terms
y = 2
Substitute the value of x in the first equation
4x + 3y = 10
4x + 3×2 = 10
Multiply the terms
4x + 6 = 10
4x = 10 - 6
4x = 4
x = 4 / 4
Divide the terms
x = 1
Hence, the solutions of the equations are x = 1 and y = 2

Answer:
It says "I'm using rude words!"
We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
