The value of x in the given expression is; x = wz/y
<h3>How to change subject of formula?</h3>
We are given the expression;
w/x = y/z
Now, we want to find the value of x which means we want to make x the subject of the formula. Thus;
Multiply both sides of the given expression by x to get;
(w/x)*x = (y/z)*x
⇒ w = xy/z
Now, multiply both sides by z/y to get;
w(z/y) = (xy/z) * (z/y)
wz/y = x
Thus, the value of x in the given expression is;
x = wz/y
The correct question is;
If w/x = y/z, then what is the value of x

Answer:
Refer below
Step-by-step explanation:
a) a and b are the lower and higher values of the interval for which uniform distribution is defined.
Here a= 6 and b =10
b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8
Or int x (1/4) dx = x^2/8 = 8
c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12
= 36/12 =3
Std dev = sq rt of 3 = 1.732
d) To find total area
PDF of the distribution = 1/(b-a) = 1/4, 6<x<10
Area = \int 6 to 10 of 1/4 dx
= x/4
Subtitute limits
= (10-6)/4 =1
So total area = 1
d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4
e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2
Answer:
Irrational
Step-by-step explanation:
Square root if 12 is 3.464 and the square root of 3 is 1.732. You multiply 3.464 and 1.732 to get 5.99 which would be 6 if you round it up. The reason to why it's irrational is because 6 can not be written as a ratio of two integers, which means it cannot be expressed as a fraction.
To the nearest hundredth is 3 digits to the left of the decimal point.
We look at the digit to the right of that number.
If that number is 5 or higher, we round up. Else, round down.
5 is our third digit to the left of the decimal point. 5 is right beside that, therefore we round up.
555.555 rounded to the nearest hundredth is 600.
Hi!
So, x is going to be the price of one apple. We need to solve for x, so let's start with getting an equation up and running.
<em>3x + 0.84 = 5x
Now, we're going to subtract three from both sides.
3x - 3x + 0.84 = 5x - 3x
Now, we're going to divide 2 from both sides!
0.84 / 2 = 2x / 2
And our final answer is... 0.42 for each apple! =)
