Write the equation y=-1/2x+3 in standard form.

1 answer:

7 0

Begin by multiplying both sides by 2 to get rid of the fraction. The standard form for a line is Ax + By = C, no fractions allowed. By multiplying we get 2y=-1x+3. Now move the -1x over by adding and we have the standard form we are looking for: x + 2y = 3.

What is the y-intercept of y = 5x - 1?

Serhud [2]

Answer:

Given Equation: y=5x-1

as we know that the y intercept have, x coordinate(absicasse) equal to 0

so,put x=0 to get y intercept

i.e, y =5×0 -1

i.e, y= -1

The random variable X is exponentially distributed, where X represents the waiting time to be seated at a restaurant during the

erastova [34]

Answer:

The probability that the wait time is greater than 14 minutes is 0.4786.

Step-by-step explanation:

The random variable X is defined as the waiting time to be seated at a restaurant during the evening.

The average waiting time is, β = 19 minutes.

The random variable X follows an Exponential distribution with parameter $\lambda=\frac{1}{\beta}=\frac{1}{19}$ .

The probability distribution function of X is:

$f(x)=\lambda e^{-\lambda x};\ x=0,1,2,3...$

Compute the value of the event (X > 14) as follows:

$P(X>14)=\int\limits^{\infty}_{14} {\lambda e^{-\lambda x}} \, dx=\lambda \int\limits^{\infty}_{14} {e^{-\lambda x}} \, dx\\=\lambda |\frac{e^{-\lambda x}}{-\lambda}|^{\infty}_{14}=e^{-\frac{1}{19} \times14}-0\\=0.4786$

Thus, the probability that the wait time is greater than 14 minutes is 0.4786.

- In 1927, Charles Lindbergh had his first

Hitman42 [59]

Answer:

Each hour he fly 107.76 miles

Step-by-step explanation:

we know that

Charles Lindbergh flew 3,610 miles in 33.5 hours

To find out the unit rate, divide the total distance by the total time

$\frac{3,610}{33.5}= 107.76\frac{miles}{hour}$

therefore

Each hour he fly 107.76 miles
