MrRa [10]

Theoretical probability is based on the likelihood of events.

if a coin is flipped 20 times, and it has landed on heads 4 times, theres a 50% chance it would land on heads the 5th time.

it could be that heads gets more than tails or it could be vise versa.

The probability of getting two heads is 1 in 4.

Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p

wariber [46]

Answer:

p = g - 50

Step-by-step explanation:

profit = income - expenses

income = 1 * g = g

expenses = $50

p = g - 50

If g = 50, then

p = 50 - 50 = 0

If she sells 50 glasses of lemonade, she breaks even. That means she makes no profit, but also she loses nothing.

If she sells more than 50 glasses, then she makes a profit.

icang [17]

Another way to think about this is... The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes. <span>This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes ).</span>

447 = -6 + 3(n - 1)

Irina-Kira [14]

After solving the equation: $447 = -6 + 3(n - 1)$ the value of n is $n=152$

Step-by-step explanation:

We need to solve the equation: $447 = -6 + 3(n - 1)$ and find value of n

Solving:

$447 = -6 + 3(n - 1)$

Multiply 3 with terms inside the bracket

$447 = -6 + 3n -3\\447=3n-9$

Adding 9 on both sides

$447+9 =3n-9+9\\456=3n\\=> 3n=456$

Divide both sides by 3

$n=456/3\\n=152$

So, after solving the equation: $447 = -6 + 3(n - 1)$ the value of n is $n=152$
