Answer:

Median is the middle of the data set. For example this data set is 4, 6, 7, 9, 10. First you take out 4 and 10. The you take out 6 and 9 to get a median of 7. But if there is an even amount of numbers like in this data set, 1, 2, 4, 5. Then you take out 1 and 5 and then find the middle point in between 2 and 4 which is 3.

Answer:

D. 18

Step-by-step explanation:

The polygon given is a 5-sided polygon (pentagon). Sum of all interior angles of a 5-sided polygon = (n - 2) * 180°

= (5 - 2) * 180 = 540°

Therefore:

95° + (7x - 4)° + (3x + 23)° + (9x - 6)° + 90° = 540°

Solve for x

95 + 7x - 4 + 3x + 23 + 9x - 6 + 90 = 540

Add like terms

198 + 19x = 540

19x = 540 - 198

19x = 342

x = 342/19

x = 18

Suppose two 1-6 number cubes are rolled. find the probability of each outcome. P(1 or 5)

stich3 [128]

Answer:

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

Step-by-step explanation:

Probability of each outcome with one cube = Number of favorable events for each outcome/Total number of possible events

Replacing with the real values, we have:

Probability of each outcome with one cube = 1/6

Probability of each outcome with two cubes = 1/6 * 1/6 = 1/36

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

the length of a rectangle is 4 inches greater than the width. The perimeter of the rectangle is 24 inches what are the dimension

deff fn [24]

Perimeter P=2L+2W
P=24
L=w+4
P=2(w+4)+2w
24=2w+8+2w
24=8+4w
16=4w
w=4

Write the equation, in slope-intercept form, of the line passing through the origin and the point $(-4,3)$.

netineya [11]

If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope $m$ . To do that we are going to use the slope formula: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .
From our two points we can infer that $x_{1}=0$ , $y_{1}=0$ , $x_{2}=-4$ , $y_{2}=3$ . Lets replace those values in the slope formula:
$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m= \frac{3-0}{-4-0}$
$m= \frac{3}{-4}$
$m=- \frac{3}{4}$

Now that we have our slope, we can use the slope-intercept formula:
$y-y_{1}=m(x-x_{1})$
$y-0=- \frac{3}{4} (x-0)$
$y=- \frac{3}{4} x$

We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is $y=- \frac{3}{4} x$ .
