Answer:
See below
Step-by-step explanation:
x = part 1
3x = part 2
x + 3x = part 3 summed, they equal 1000
x + 3x + x + 3x = 1000
8x = 1000
<u>x = 125 3x = 385 third part = 500 </u>
Answer:
they bisect each other
Step-by-step explanation:
<em>The diagonals of a parallelogram bisect each other</em>.
__
If they are the same length, the parallelogram is a rectangle. If they cross at right angles, it is a rhombus.
We have, 32% × x = 3000
or, 32100 × x = 3000
Multiplying both sides by 100 and dividing both sides by 32,
we have x = 3000 × 10032
x = 9375
If you are using a calculator, simply enter 3000×100÷32, which will give you the answer.
Answer - 100,000
Answer:
a) 0.3889
b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:

The probability of finding a value of X between c and d is:

The mean and the standard deviation are, respectively:


A random variable follows the continuous uniform distribution between 160 and 340.
This means that 
a)

b)

c)

d)


The mean is 250 and the standard deviation is 51.96.
Answer:

Step-by-step explanation:
hello
-4 <= x <= 6
or we can say as well
x >= -4 and x <= 6
hope this helps
