Answer: y=3
Step-by-step explanation: 6(4.5y−12)=9
Step 1: Simplify both sides of the equation.
6(4.5y−12)=9
(6)(4.5y)+(6)(−12)=9(Distribute)
27y+−72=9
27y−72=9
Step 2: Add 72 to both sides.
27y−72+72=9+72
27y=81
Step 3: Divide both sides by 27.
27y/27 =81/27
You're given that the formula for area is lw, and you're given the l and w values. So just plug them in. They have the same unit of measurement (inches) so you can just multiply.
A = lw
A = (5.5)(2.1)
A = 11.55 in²
Responder:
1,625; 0.8569
Explicación paso a paso:
y ___0 ____ 1 ____ 2 ____3
P (y) _1 / 8 ___ ¼ ___ ½ ____ 1/8
Valor esperado (E (x)): Σx * p (x)
= (0 * (1/8)) + (1 * (1/4)) + (2 * (1/2)) + (3 * (1/8)) = 1,625
La desviación estándar = sqrt (Var (x))
Var (X) = Σx²p (x) * E (x) ²
Var (X) = [(0 ^ 2 * (1/8)) + (1 ^ 2 * (1/4)) + (2 ^ 2 * (1/2)) + (3 ^ 2 * (1 / 8))] - 1.625²
Var (X) = (0 * (1/8)) + (1 * (1/4)) + (4 * (1/2)) + (9 * (1/8)) - 1.625 ^ 2
= 3.375 - 2.640625
= 0,734375
Desviación estándar = Sqrt (0,734375) = 0,8569
