Simplifying

4x + 16 + -1x = 22 + 6

Reorder the terms:

16 + 4x + -1x = 22 + 6

Combine like terms: 4x + -1x = 3x

16 + 3x = 22 + 6

Combine like terms: 22 + 6 = 28

16 + 3x = 28

Solving

16 + 3x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-16' to each side of the equation.

16 + -16 + 3x = 28 + -16

Combine like terms: 16 + -16 = 0

0 + 3x = 28 + -16

3x = 28 + -16

Combine like terms: 28 + -16 = 12

3x = 12

Divide each side by '3'.

x = 4

Simplifying

x = 4

An airline is planning its staffing needs for the next year. If a new route is approved, it will hire 858 new employees. If a n

stealth61 [152]

Answer:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And from the problem we know the following:

$P(X_1) = 0.34 , X_1 =858$ represent the condition if the route is approved

$P(X_2) = 1-0.34=0.66 , X_1 =157$ represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

$E(X) = 858*0.34 + 157*0.66 = 395.34$

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.

Step-by-step explanation:

For this cae we can define the random variable X who represent the number of new employees to be hired by the airline and we can find the expected value with the following general formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And from the problem we know the following:

$P(X_1) = 0.34 , X_1 =858$ represent the condition if the route is approved

$P(X_2) = 1-0.34=0.66 , X_1 =157$ represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

$E(X) = 858*0.34 + 157*0.66 = 395.34$

So then the expected number of new employees to be hired by the airline based on the conditions given is between 395 and 396.

Whats a line passing<br> through the<br> points (0, 0) and<br> (5,-7)?

Ipatiy [6.2K]

Answer:

y = -7/5x

Step-by-step explanation:

First, we need to use the two points to find the slope.

m = y₁ - y₂ / x₁ - x₂

m = -7 - 0 / 5 - 0

m = -7/5

Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.

y - y₁ = m(x - x₁)

y - (-7) = -7/5(x - 5)

y + 7 = -7/5x + 7

y = -7/5x

Therefore, the equation of the line is y = -7/5x.
