Answer:

The equation in slope intercept form (y = mx + b) is y = 2x - 4

m = the slope

b = the y intercept

The line cross the y-axis at -4 so the y-intercept (b) is -4.

You can use the slope formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.

$\frac{0--4}{2-0}$ = $\frac{4}{2}$ = 2

So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

Explanation:
His original debt: money paid for 10 months + remaining debt
Assume X is his original debt
Then X= 10 • 150 + 6900
X= 1500+6900=8400$

Delta Airlines quotes a flight time of 2 hours, 5 minutes for its flights from Cincinnati toTampa. Suppose we believe that actua

siniylev [52]

Answer:

a) The graph of the probability density function for flight time is shown below.

b) 1/2

c) 0

d) 130 minutes

Step-by-step explanation:

Let's deal with the flight times in minutes instead of hours, and let T be the random variable that represents the flight time. T is uniformly distributed between 120 minutes and 140 minutes. The probability density function for T is given by

$f(t)=\frac{1}{140-120}=\frac{1}{20}$ for t in [120, 140]

a) The graph of the probability density function for flight time is shown below.

Delta Airlines quotes a flight time of 125 minutes for its flights from Cincinnati to Tampa.

b) The probability that the flight will be no more than 5 minutes late is given by

$P(T \leq 125 + 5) = P(T \leq 130) = \int\limits_{120}^{130}\frac{1}{20}dt = \frac{1}{20}(130-120)= \frac{1}{20}(10) = \frac{1}{2}$

c) The probability that the flight will be more than 10 minutes late is given by

$P(T \geq 125 + 10) = P(T \geq 135) = 0$ because the probability density function is zero for t outside of [120, 140]

d) The expected flight time is given by $E(T) = \frac{120+140}{2} = \frac{260}{2} = 130$ minutes

kipiarov [429]

Answer:

answer is 4

I hope it helped

Step-by-step explanation:

$f(x) = \sqrt{x} - 2\\$

which is basically

$0 = \sqrt{x} - 2$

$2 = \sqrt{x}$

$2^{2} = x$

$x = 4$

The results of a 10-kilometer run are shown in the table. Use the drop-down menus to complete the statements below.

Allushta [10]

Answer:

Your drop down menus have the following choices:

First box: faster than, slower than, at the same rate as.

Second box: greatest x-value, line, y-intercept, slope.

Third box: greater than, less than, equal to.

Fourth box: greatest x-value, x-intercept, y-intercept, slope, origin.

Fifth box: minutes per gallon, gallons per minute.

Pool A is filling up slower than Pool B because the slope of the graph of Pool A is less than that of the graph for Pool B.

The slope of the graph tells you the unit rate in gallons per minute.

Select all the equations that have no solution

kykrilka [37]

Answer:

A, E

Step-by-step explanation:

x + 6 = 5+x can not be a solution. This is because both of the x's will cancel each other out.

5 - 3x = -3x +4 can not be a solution. The negative 3x's will cancel each other out if you try to balance both sides by doing +3x on both sides.
