A dance studio requires each dancer to pay a registration fee plus an hourly rate for all lessons. If the total cost, y, of a da

ncer's lesson is modeled by the equation y = 25x + 50, how could the y-intercept be interpreted?

Answer:

(0,50)

Step-by-step explanation:

Given the total cost of a dancers lesson  modeled by the equation y = 25x + 50, the y intercept occurs at the point where x = 0.

Substitute x = 0 into the expression

y = 25x + 50

y = 25(0) + 50

y = 0+50

y = 50

Hence the y intercept is (0, 50). This shows that the total cost of the dancers lesson registration fee is 50

the probability that we encounter a green light at the corner of college and main is 0.35, a yellow light 0.04, and a red light
Ostrovityanka [42]

Answer:

21% probability you will hit a green light on monday and a red light on tuesday

Step-by-step explanation:

When two events, A and B, are independent, we have that:

P(A \cap B) = P(A) \times P(B)

In this problem, we have that:

Event A: Green light on monday.

Event B: Red light on tuesday.

The probability that we encounter a green light at the corner of college and main is 0.35

This means that P(A) = 0.35

The probability that we encounter a red light is 0.61:

This means that P(B) = 0.61

These events are independent, that is, the light color on Tuesday is independent of the color on Monday. So

P(A \cap B) = P(A) \times P(B) = 0.35 \times 0.6 = 0.21

21% probability you will hit a green light on monday and a red light on tuesday

After an office party, 4 1/3 pizzas are left. A day later, there are 1 5/6 pizzas left. How munch pizza was eaten during the day
IceJOKER [234]

Answer:

15/6 pieces of pizza were eaten. Which is equivalent to 2.5. So 2.5 pizzas were eaten.

Step-by-step explanation:

Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.

Solve the following system of equations graphically on the set of axes below.
Montano1993 [528]

You need to plot each line and see where they intersect.

Line 1: y = x+2

Plot the y-intercept (0,2) because of the +2 in the equation.

From (0,2), count "up 1, right 1" to get a second point, because the slope is 1.

From that new point, repeat the "up 1, right 1" to plot a third point.

Connect the dots to make your line.

Line 2: y = -1/3 x - 2

Repeat the same process, using the the y-intercept and slope for this line.

Then identify where they intersect.
