The price of one vegetarian special lunch is $7 and price of one chicken special lunch is $8.
Step-by-step explanation:
Let,
Price of one vegetarian special lunch = x
Price of one chicken special lunch = y
According to given statement;
21x+40y=467 Eqn 1
28x+36y=484 Eqn 2
Multiplying Eqn 1 by 28
Multiplying Eqn 2 by 21
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 364
Putting y=8 in Eqn 1
Dividing both sides by 21
The price of one vegetarian special lunch is $7 and price of one chicken special lunch is $8.

Answer:
that is step 1 and step 2 and step3
step 4
Let's solve your equation step-by-step.
−4(x+2)=8x+16
Step 1: Simplify both sides of the equation.
−4(x+2)=8x+16
(−4)(x)+(−4)(2)=8x+16(Distribute)
−4x+−8=8x+16
−4x−8=8x+16
Step 2: Subtract 8x from both sides.
−4x−8−8x=8x+16−8x
−12x−8=16
Step 3: Add 8 to both sides.
−12x−8+8=16+8
−12x=24
Step 4: Divide both sides by -12.
−12x

Answer:
30 and 3.4641
Step-by-step explanation:
The mean of a binomial distribution is:
μ = np
And the standard deviation of a binomial distribution is:
σ = √(npq)
Here, n = 50, p = 0.60, and q = 0.40.
μ = np = 50 × 0.60 = 30
σ = √(npq) = √(50 × 0.60 × 0.40) = 3.4641
