Answer:
The mean means there are as many points below as above the mean point. Adding pairs of points to the left and right of the mean does not change the mean since the count on the left and right change at the same rate.
Step-by-step explanation:
Rowena sells a dress for $42.60 after making a profit of 20% on the cost price.
Calculate the cost price.
20
$ ...................................................
Answer:
$35.50
Step-by-step explanation:
With a 20% profit then $42.60 represents 120%
We require to find the cost price represented by 100%
Divide the amount by 120 to find 1% then multiply by 100, that is
cost price = [tex]\frac{46.60}{120}[/tex] × 100 = $35.50

Answer:
x = 1/2 , x = 1/4 , x = 1/3
Step-by-step explanation:
Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0
You will get ----> (2x - 1) (4x - 1) (3x - 1) = 0
Now make all the above expressions = 0 and solve.
2x - 1 = 0 4x - 1 = 0 3x - 1 = 0
+1 +1 +1 +1 +1 +1
------------------ ------------------ ------------------
2x = 1 4x = 1 3x = 1
/2 /2 /4 /4 /3 /3
------------------- ------------------- ----------------------
x = 1/2 x = 1/4 x = 1/3

AB = 2x – 17, AC = 14, and BC = x + 1.
Find x.
9514 1404 393
Answer:
x = 10AB = 3BC = 11Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3
BC = 10+1 = 11

Answer:
168000
Step-by-step explanation:
5/14 to the son.
that leaves 9/14 of the total.
these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.
how do we do that ?
well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).
but in general by multiplying. so 2/3 of 8/14 is
9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14
and then little surprising 1/3 is
9/14 × 1/3 = 9 / 14×3 = 3/14
now, we know, these 3/14 are 36000.
what we need to know is how much is 14/14 or 1/1 : the whole amount.
well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).
it in total, multiply it with the reverse fraction : 14/3
36000 × 14/3 = 12000×14 = 168000

A line passes through the points (1, 7) and (0, 3). What is its equation in slope-intercept form?
Answer:
y=4x-12
Step-by-step explanation:
The slope of the line is (7-3)/(1-0)=4. The equation of the line is y=4x-12
Adjacent sides of Figure 1 are perpendicular. Four sides of Figure 1 are removed to form Figure 2. What is the total length, in units, of the segments in Figure 2?
Answer:
19
Step-by-step explanation:
Here ( left and right) side 8 and 6 are same in both
in fig 1 base side is 1 +2 + 1 =4
so in figure 2 it will be also 4
and at last only 1 unit in fig 1 ( upside) is taken in figure 2
so total addition is...
8 + 6 + 4 + 1
= 19

find the slope of the line that is perpendicular to the line graphed in the figure
Answer:
- [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = [tex]\frac{1-(-4)}{1-0}[/tex] = [tex]\frac{1+4}{1}[/tex] = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex]
