Write two equations for two perpendicular lines that have the same y intercept and do not pass through the same origin 15Points

Zanzabum

Two equations for two perpendicular lines that have the same y-intercept and do not pass through the same origin are; y = x + 1 and y = -x + 1

<h3>What is the equation of the two lines?</h3>

The general formula for the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, when we talk about two perpendicular lines, it means that their slopes are negative reciprocals of each other.

Secondly, we are told that they both do not pass through the origin. Thus, it means that the y-intercept cannot be zero.

Therefore, two possible equations here can be;

y = x + 1 and y = -x + 1

Suppose the probability that a randomly selected man, aged 55 - 59, will die of cancer during the course of the year is StartF

sveticcg [70]

Answer:

The probability that a man in this age category does NOT die of cancer during the course of the year is 0.997.

Step-by-step explanation:

Suppose the probability of an event occurring is $P_{i}$ .

The probability of the given event not taking place is known as the complement of that event.

The probability of the complement of the given event will be,

$1 - P_{i}$

In this case an events X is defined as a man, aged 55 - 59, will die of cancer during the course of the year.

The probability of the random variable X is:

$P (X) = \frac{300}{100000}=0.003$

Then the event of a man in this age category not dying of cancer during the course of the year will be complement of event X, denoted by X'.

The probability of the complement of event X will be:

$P(X')=1-P(X)$

$=1-0.003\\=0.997$

Thus, the probability that a man in this age category does NOT die of cancer during the course of the year is 0.997.

Evaluate [(40 + 5) − 32] ÷ 9 ⋅ 2

crimeas [40]

(45 - 32) / 9 x 2
13 / 9 x 2
13/9 x 2
13 x 2/9
thus, 26/9
or 2 8/9
or 2.8888888888
