How to find the slope of the line passing through one point and has a slope?

1 answer:

6 0

You can do this in a number of ways, but the easiest is to plug the numbers into slope-intercept form and solve for the y-intercept (b). The formula is below with slope = m.

y = mx+b

After you've solved for b, but place m and b into the equation and you will have the line.

Paulo catches a 7.45 am tram to school. During a period of 79 days, he arrives at school on time 53 occasions. Estimate the prob

Answer:

On time: 0.67

Late: 0.33

Step-by-step explanation:

Probabilities

One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).

The probability can be estimated with the formula:

$\displaystyle P=\frac{e}{n}$

And the probability that the event doesn't occur is

Q = 1 - P

Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:

$\displaystyle P=\frac{53}{79}$

P = 0.67

And the probability he arrives late is:

Q = 1 - 0.67 = 0.33

Lines m and p are perpendicular. If the slope of line m is -3, what is the slope of line p?

nika2105 [10]

Answer: The slope of p is 1/3

Step-by-step explanation:

If the lines are perpendicular, this means they are opposite.

Thus, O is opposite P and since O = -3, P = 1/3
