Let us consider the ration of two numbers be x
The two numbers are 5x and 3x
Since two numbers differ by 18, we can write the equation
5x – 3x = 18
2x = 18
x= 9
Therefore the two numbers are
5x = 5 x 9 = 45
and
3x = 3 x 9 = 27
∴ The two numbers are 45 and 27.

Answer:
[tex]m =13[/tex]
Step-by-step explanation:
Given
The attached dataset
Required
The mean absolute deviation
First, calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{42+40+39+76+71+55+68+65}{8}[/tex]
[tex]\bar x = \frac{456}{8}[/tex]
[tex]\bar x = 57[/tex]
The mean absolute deviation (m) is:
[tex]m =\frac{1}{n} \sum|x - \bar x|[/tex]
So, we have:
[tex]m =\frac{1}{8} (|42 - 57| + |40 - 57| + |39 - 57| + |76 - 57| + |71 - 57| + |55 - 57| + |68 - 57| + |65 - 57|)[/tex]
Using a calculator, we have:
[tex]m =\frac{1}{8} (|-15| + |-17| + |-18| + |19| + |14| + |-2| + |11| + |8|)[/tex]
Remove absolute bracket
[tex]m =\frac{1}{8} (15 + 17 + 18 + 19 + 14 + 2 + 11 + 8)[/tex]
[tex]m =\frac{1}{8} *104[/tex]
[tex]m =13[/tex]
The mean absolute deviation is 13

Maria says the mean for the following data set is 5. {5, 7, 2, 8, 9, 1, 2, 5}
What is the actual mean? (Round to the nearest hundredth)
What did Maria do wrong? In other words, what average did she give instead?
Answer:
4.88
Step-by-step explanation:
I used my calculator to do this;
I did stat and I put in the numbers, I clicked calculate and it said the answer was 4.875. Round that to the nearest hundredth and you'll get 4.88.
Answer:
4.88
Step-by-step explanation:
The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.
I think she gave an approximated average or a rounded average, but I am not sure.

what is the area in square inches of the trapezoid below.
Answer:
50 in²
Step-by-step explanation:
What is the area in square inches of the trapezoid below.
Area of a trapezoid = 1/2(b1 + b2) h
Where
b1 = First base = 8in
b2 = Second base = 12in
h = Height = 5in
Area of trapezoid = 1/2(8 + 12) × 5
= 1/2 × 20 × 5
= 50 in²
The area of the trapezoid is 50 square inches

.Un recipiente cilíndrico de 5cm de radio y 10cm de altura se llena de agua. Si la masa del recipiente lleno es de 2kg, ¿cuál es la masa del recipiente vacío?
Answer:
La masa del recipiente vacío es 1,2146 kg.
Step-by-step explanation:
La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]densidad= \frac{masa}{volumen}[/tex]
Entonces la masa puede ser expresada como:
masa= densidad*volumen
En este caso:
densidad del agua= 1000 [tex]\frac{kg}{m^{3} }[/tex]volumen del recipiente cilíndrico= π*radio²*altura= π*(5 cm)²* 10 cm= π*(0,05 m)²*0,1 m= 7,854*10⁻⁴ m³Reemplazando:
masa= 1000 [tex]\frac{kg}{m^{3} }[/tex] * 7,854*10⁻⁴ m³
masa=0.7854 kg
Si la masa del recipiente lleno es de 2 kg, entonces se le resta la masa de agua calculada:
2 kg - 0,7854 kg= 1,2146 kg
Entonces, la masa del recipiente vacío es 1,2146 kg.

If f(x)=x^3-4x^2-37x+40f(x)=x 3 −4x 2 −37x+40 and f(8)=0f(8)=0, then find all of the zeros of f(x)f(x) algebraically.
Given:
The function is:
[tex]f(x)=x^3-4x^2-37x+40[/tex]
[tex]f(8)=0[/tex]
To find:
The all of the zeros of f(x) algebraically.
Solution:
We have, [tex]f(8)=0[/tex] is means 8 is a zero of given function and (x-8) is a factor of given function.
The function is:
[tex]f(x)=x^3-4x^2-37x+40[/tex]
Spittle the middle terms in such a way so that we get (x-8) as a common factor.
[tex]f(x)=x^3-8x^2+4x^2-32x-5x+40[/tex]
[tex]f(x)=x^2(x-8)+4x(x-8)-5(x-8)[/tex]
[tex]f(x)=(x^2+4x-5)(x-8)[/tex]
Spittle the middle term of the quadratic expression, we get
[tex]f(x)=(x^2+5x-x-5)(x-8)[/tex]
[tex]f(x)=(x(x+5)-1(x+5))(x-8)[/tex]
[tex]f(x)=(x+5)(x-1)(x-8)[/tex]
For zeros, [tex]f(x)=0[/tex].
[tex](x+5)(x-1)(x-8)=0[/tex]
[tex](x+5)=0\text{ and }(x-1)=0\text{ and }(x-8)=0[/tex]
[tex]x=-5\text{ and }x=1\text{ and }x=8[/tex]
Therefore, the all zeros of the given function are -5, 1 and 8.

Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord, that is
5x × x = 5 × 9
5x² = 45 ( divide both sides by 5 )
x² = 9 ( take the square root of both sides )
x = [tex]\sqrt{9}[/tex] = 3
A construction company built a scale model of a new building. the model was built usinga scale of 3 inches= 32 feet. if the building is expected to be 200 feet tall, how tall is the model?
Answer: 18.75 inches
Step-by-step explanation:
Let the height of the model be represented by x. Therefore, based on the information given in the question, we can form an equation which will be:
3/x = 32/200
Cross multiply
32 × x = 200 × 3
32x = 600
x = 600/32
x = 18.75
Therefore, the height of the model is 18.75 inches
8th grade work math.
Answer:
3rd option
Step-by-step explanation:
Consider the coordinates of A and A'
A (0, 0 ) and A' (5, 2 )
This represents a move of + 5 (0 → 5) units in the x- direction and a move of + 2 ( 0 → 2 ) units in the y- direction.
The figure is unchanged and must therefore be a translation with rule
(x, y ) → (x + 5, y + 2 )
Can anyone help me solve this
I NEED HELP ASAP PLEASE!! ;)
Answer:
7 inches
Step-by-step explanation:
First you have to find the average height of each class.
4th Grade:
56, 47, 54, 51, 53, 58, 48, 54, 46, 53
Then you have add it all up and divide it by how many students there are.
56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520
520 ➗10= 52
Same process for the 7th Grade.
You end up getting 52 and 59. You then Subtract it to get the answer to the question.
52 - 59= 7 inches

y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above
