At the north campus of a performing arts school, 10% of the

Alecsey [184]

There were 600 students at the north campus and 400 students at the south campus.

<h2 /><h3><u>Calculus</u></h3>

To determine, if 42% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger, the following calculation must be performed:

0.10X + 0.90Y = 420
1000 x 0.42 = 420
500 x 0.10 + 500 x 0.90 = 50 + 450 = 500
600 x 0.10 + 400 x 0.90 = 60 + 360 = 420

Therefore, there were 600 students at the north campus and 400 students at the south campus.

When a number is substituted for the same variable in two expressions, how many times must those two expressions have different

zysi [14]

Answer:

Hope this helps!!!

Step-by-step explanation:

An equation is a mathematical statement that two expressions are equal. The solution of an equation

is the value that when substituted for the variable makes the equation a true statement.

Our goal in solving an equation is to isolate the variable on one side of the equation and a number on

the other side so the equation reads:

Variable = Number

To achieve our goal, we use two principles of equality, the addition principle and the multiplication

principle.

• Use the addition principle to move terms from one side of the equation to the other side. To

move a term, add it's opposite to both sides of the equation.

• Use the multiplication principle to solve for the variable. If the variable is multiplied by a

number, divide both sides of the equation by that number. If the variable is divided by a

number, multiply both sides of the equation by that number.

To solve equations, use the procedure outlined below.

Steps for Solving Equations

Step 1: Clear fractions and decimals by multiplying each term of the equation by the LCD (least

common denominator).

Step 2: Remove the parentheses by distributing.

Step 3: Combine any like terms found on the same side.

Step 4: Use the addition principle to move the variable term to one side of the equation and the

number to the other side.

Step 5: Multiply or divide to solve for the variable.

Step 6: Check the result in the original equation.

The average number of customers arriving at a gas station is 33 per hour during lunch hours. Use equation to denote the number o

Paha777 [63]

Answer:

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is 2.75.

Step-by-step explanation:

Let <em>X</em> = number of customers arriving at a gas station in an hour.

The average customers arriving at a gas station in an hour is, <em>λ</em> = 33.

The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em>.

The probability mass function of a Poisson distribution is:

$P(X=x)=\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,3...$

In 60 minutes the number of arrivals is, 33.

In 1 minute the number of arrival will be, $\frac{33}{60}$ .

Then in 5 minutes the number of arrivals will be, $\frac{33}{60}\times5$ .

The equation denoting the number of arrivals in 5 minutes is, $\frac{33}{60}\times5$ .

The number of arrivals in 5 minutes is

$\frac{33}{60}\times5=2.75$

Thus, the number of arrivals in 5 minutes is 2.75.
