N. B, a dice has 6faces so 2dice has 12 faces
The central 50 percent of data around average
So, making x subject of the formula, x = [m - 2pt³ ±√(m² - 4pt²m)]/{2t⁵}
<h3>How to make x subject of the formula?</h3>
Since p = √(mx/t) - t²x
So, p + t²x = √(mx/t)
Squaring both sides, we have
(p + t²x)² = [√(mx/t)]²
p² + 2pt²x + t⁴x² = mx/t
Multiplying through by t,we have
(p² + 2pt²x + t⁴x²)t = mx/t × t
p²t + 2pt³x + t⁵x² = mx
p²t + 2pt³x + t⁵x² - mx = 0
t⁵x² + 2pt³x - mx + p²t = 0
t⁵x² + (2pt³ - m)x + p²t = 0
Using the quadratic formula, we find x.
where
- a = t⁵,
- b = (2pt³ - m) and
- c = p²t
Substituting the values of the variables into the equation, we have
So, making x subject of the formula,

Answer:
cost of bracelet = 25*.05 +4*.45
cost of bracelets = 2(25*.05 +4*.45)
Step-by-step explanation:
One bracelet
Supplies needed:
25 beads and 4 charms
Each bead costs .05 and each charm costs .45
Cost of bracelet = number of beads * cost per bead + number of charms * cost per charm
cost of bracelet = 25*.05 +4*.45
cost of bracelet = 1.2 +1.8
=3.00
To make 2 bracelets
Cost of bracelets =2*( number of beads * cost per bead + number of charms * cost per charm)
cost of bracelets =2*( 25*.05 +4*.45)
cost of bracelets=2( 1.2 +1.8)
cost of bracelets = 2*3
cost of bracelets = 6
