Answer:
w = -2 or 8 1/3
Step-by-step explanation:
Setting the two expressions equal makes a quadratic equation:
-5 +0.6w = w(2.5 -0.3w)
0.3w^2 -1.9w -5 = 0 . . . . . . subtract the right-side expression
3w^2 -19s -50 = 0 . . . . . . . multiply by 10 to give integer coefficients
(3w -25)(w +2) = 0 . . . . . . . factor
We can use the zero product rule to find the solutions. The product will be zero only if a factor is zero.
3w -25 = 0 ⇒ w = 25/3 = 8 1/3
w +2 = 0 ⇒ w = -2
The values of w that make the two expressions equivalent are -2 and 8 1/3.
Answer:
B is the answer.
A) No because the value of x depends on what 7•y is
C) No because x depends on the value of y+7
D) No because the x depends on the value of y/7
In other words, on B, x doesn't depend on anything, your just given the value of it. Don't know how else to explain it, hope you get it.
Answer:5/5 then 10-7 then 6/2
Step-by-sanation:
Using the given information, the value of Σfd is 800
<h3>Calculating mean using Assumed mean </h3>
From the question, we are to determine the value of Σfd
The formula for mean, using the assumed mean method is given by
Where 
is the mean
A is the assumed mean
From the given information,
Putting the parameters into the equation, we get
Hence, the value of Σfd is 800
