Answer:

-5/2

Step-by-step explanation:

Use slope formula:

Given 2 points (x1, y1) and (x2, y2) Slope is

y2-y1/x2-x1

The x intercept is 2, the point would be (2,0)

The y intercept is 5, the point would be (0,5)

So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2

Answer:
-5/2

Explanation:
We are given two points from the problem: (2,0) and (0,5). Using these two points, we can calculate the slope using the formula y2-y1/x2-x1 by plugging in points (x1,y1) and (x2,y2).

y2-y1/x2-x1
0-5/2-0
-5/2

Therefore, the slope of the line is -5/2.

I hope this helps!

If AD is the altitude to BC, what is the slope of AD?

anygoal [31]

Answer:

Option (C)

Step-by-step explanation:

If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.

By the property of perpendicular lines,

$m_1\times m_2=-1$

where $m_1$ is the slope of the line AD and $m_2$ is the slope of BC.

$m_2=\frac{y_2-y_1}{x_2-x_1}$

$=\frac{8+2}{3-7}$

$=-\frac{5}{2}$

Now from the given property,

$m_1\times (-\frac{2}{5})=-1$

$m_1=\frac{5}{2}$

Therefore, slope of altitude BC = $\frac{5}{2}$

Option (C) will be the answer.

Statistics show on average an adult person receives 425 pieces of mail each year with a standard deviation of 50. What are the m

Kisachek [45]

Answer:

The answer is 60.11

Step-by-step explanation:

An adult person receives 425 pieces of mail each year with a standard deviation of 50.

Now, we have the following details :

Mean of sample = 425

sigma = 50

Standard error = $\frac{425}{\sqrt{50} }$

= $\frac{425}{7.07}$ = 60.11
