A survey was given to a random sample of the residents of a town to determine whether they support a new plan to raise taxes in order to increase education spending. The survey reported a confidence interval that between 16.5% and 25.5% of the residents supports the plan. What is the margin of error on the survey? Do not write \pm± on the margin of error.
Answer:
9
Step-by-step explanation:
The confidence interval is related to margin of error ; according to the relation :
Confidence interval = mean ± margin of error
Margin of Error = (upper boundary value - lower boundary value)
Confidence interval = 16.5% and 25.5%
Margin of Error = (25.5% - 16.5%)
Margin of Error = ±9
The margin of error on the survey is 9.
We know that
Confidence interval = mean ± margin of error
And,
Margin of Error = (upper boundary value - lower boundary value)
We have Confidence interval between 16.5% and 25.5%.
upper boundary value = 25.5%
lower boundary value = 16.5%
So, Margin of Error
= 25.5% - 16.5%
=9
Therefore, Margin of Error is 9.

Expand and combine like terms.
(765 – 46)(765 + 46)
Answer:
587,341
Step-by-step explanation:
(I'm hoping this is what you mean by expand)
(765 – 46)(765 + 46)
First, multiply 765 by 765 = 585,225
Second, multiply 765 by 46 = 35,190
Third, multiply -46 by 765 = -35,190
Fourth, multiply -46 by 46 = -2,116
The second and third answers (35,190 and -35, 190) will cancel each other out. Then, just subtract -2,116 from 585,225.
585,225 - (-2,116) = 585,225 + 2,116 = 587,341

Answer:
[tex] A(\triangle ABC) =17.5 \: {units}^{2} [/tex]
Step-by-step explanation:
AB = 4 - (-3) = 4 + 3 = 7 units
BC = 3 - (-2) = 3 + 2 = 5 units
[tex]A(\triangle ABC) = \frac{1}{2} \times AB\times BC \\ \\ A(\triangle ABC) = \frac{1}{2} \times 7\times 5 \\ \\ A(\triangle ABC) = \frac{1}{2} \times 35 \\ \\ A(\triangle ABC) =17.5 \: {units}^{2} [/tex]
A rectangular playground has an area of 3,394 square meters. If the width of the playground is 32 meters, find the length.
Answer:
106 square
Step-by-step explanation:
Area of rectangle = 3,394 square meters
Width = 32 meters
Length = ?
Area of rectangle = Length * Weight
3,394 = 32 * x
x = 3,394 /32
x = 106.0625
x = 106
The Length is 106 square

Step-by-step explanation:
4. Consider the right triangle below.
If the perimeter is 1,013 units, find the value of x and the area of the
triangle.
16x + 27
14x - 45
25x
The value of x is
The area is
square units.
Answer:
16x+27+14x-45+25x=1013 units
X= 18.75
Area= b × h × (1/2)
A= 1/2 × 327 × 217.5 = 35561.25 units^2
Answers:
x = 1031/55 = 18.74545 approximatelyarea = 35,542.92 square units approximately==============================================================
Explanation:
The perimeter is the sum of the exterior sides. We'll add up these three sides
16x+2714x-4525xand set the sum equal to the perimeter 1013
The equation we need to solve is
(16x+27)+(14x-45)+(25x) = 1013
Solving for x leads to...
(16x+27)+(14x-45)+(25x) = 1013
16x+27+14x-45+25x = 1013
(16x+14x+25x)+(27-45) = 1013
55x-18 = 1013
55x = 1013+18
55x = 1031
x = 1031/55
x = 18.74545 approximately
-----------------------------
Use this x value to find the length of each side. I'll use the decimal form of x. We get the following side lengths:
16x+27 = 16*(18.74545) + 27 = 326.927214x - 45 = 14*(18.74545) - 45 = 217.436325x = 25*(18.74545) = 468.63625Those values are approximate.
We can then find the area of the triangle
area = (1/2)*base*height
area = (1/2)*(326.9272)*(217.4363)
area = 35,542.92036868
area = 35,542.92
The area is approximate as well.

Express as a trinomial. (x+3)(3x-1)
Answer:
3x^2+8x-3
Step-by-step explanation:
(x+3)(3x-1)
x*3x + x*(-1) + 3x*3 + 3*(-1)
x*3x = 3x^2
x*(-1) + 3x*3 = -x+9x = 8x
3*(-1) = -3
= 3x^2+8x-3
The expression for the trinomial ( x + 3 ) ( 3x - 1 ) is [tex]3x^{2} + 8x - 3[/tex]
Given data:
The expression is represented as (x + 3)(3x - 1)
To express the product of (x + 3)(3x - 1) as a trinomial, perform the multiplication.
Using the FOIL method (First, Outer, Inner, Last), we multiply the terms:
(x + 3)(3x - 1) = x(3x) + x(-1) + 3(3x) + 3(-1)
Simplifying further:
[tex]3x^{2} - x + 9x - 3[/tex]
Combining like terms:
[tex]3x^{2} + 8x - 3[/tex]
Hence, the expression (x + 3)(3x - 1) can be expressed as the trinomial [tex]3x^{2} + 8x - 3[/tex] .

r/1000=7, algebra, got confused and this one is weird to do. (personally)
Answer:
r = 7000Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
r/1000-(7)=0
Step by step solution :
STEP1:
r
Simplify ————
1000
Equation at the end of step1
r
———— - 7 = 0
1000
STEP 2
Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 1000 as the denominator :
7 7 • 1000
7 = — = ————————
1 1000
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
r - (7 • 1000) r - 7000
—————————————— = ————————
1000 1000
Equation at the end of step 2
r - 7000
———————— = 0
1000
STEP 3
When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
r-7000
—————— • 1000 = 0 • 1000
1000
Now, on the left hand side, the 1000 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
r-7000 = 0
Solving a Single Variable Equation:
Solve : r-7000 = 0
Add 7000 to both sides of the equation :
r = 7000
One solution was found :
r = 7000

El perímetro de un rombo es igual al de un pentagono regular más 9, y la medida del lado del rombo es el doble de lo que mide un lado del pentagono. ¿Cuánto miden los lados de cada figura?
Answer:
Rombo es 6
Pentágono es 3
Step-by-step explanation:
Formula del perímetro de un rhombus es 4a
Formula del perímetro de un pentágono es 5b
La pregunta dice
4a = 5b + 9
Otra vez, la pregunta dice la medida del lado del rombo es el doble de lo que mide un lado del pentagono. Entonces,
a = 2b
Si
4a = 5b + 9 y
a = 2b, entonces que
4(2b) = 5b + 9
8b = 5b + 9
8b - 5b = 9
3b = 9
b = 9/3
b = 3
si, b = 3, tan
a = 2(3)
a = 6
Entonces, la medida del lado del rombo es 6 y la medida del lado del pentágono es 3
