find the median and mean 42,15,14,48,39
Answer:
Hello! the answer is 39 and 32
Step-by-step explanation:
To find the median we need to reorder the numbers from lowest to highest:
14,15,39,42,48
The one in the middle is the median! If there happens to be an even number, take the two middle numbers add them, together and divide them by 2.
To find the mean (also know as the avergae) we need to add all the numbers together and divide by the number of values that are present:
42+15+14+48+39 = 158
158/ 5 = 31.6 or 32

What’s the volume of the cake if the radius is 8 inches
and the height is 5 inches?
Answer:
1005 in^3
Step-by-step explanation:
Think of this cake as a cylindrical solid of base radius 8 in and height 5 in.
The volume is V = (base area)(height), which here is:
V = (pi)*(8 in)^2*(5 in) = 320pi in^3, or approximately 1005 in^3

Cuales son las diferencias entre bisección , triseccion y bisectriz ? , por favor lo necesito urgente
Answer:
Primero, la bisección consiste en dividir una figura en dos partes iguales, esto se puede aplicar a cualquier figura, desde un segmento hasta un cuadrado o algo más complejo.
Por ejemplo, en el caso del segmento, una bisección sería una línea que corta el segmento justo por el punto medio.
Por otro lado, una trisección es similar, solo que en este caso dividimos una figura en 3 partes iguales.
Finalmente tenemos la bisectriz, esta es una semirrecta con origen en el vértice de un ángulo, de tal forma que divide al ángulo en dos partes iguales.
La bisectriz se diferencia con la bisección pues la bisectriz solo se aplica a ángulo, mientras que la bisección se aplica a cualquier figura.
Además, la bisectriz en sí misma es una figura geométrica, pues es una semirrecta, mientras que la bisección sería un operador que actúa sobre una figura, y aunque puede ser representada con una semirrecta o una recta, no es necesariamente una.
Ambas se diferencian de la trisección pues la bisectriz y la bisección dividen en dos, mientras que la trisección divide en tres.
PLEASE HELP Adam has a rectangular swimming pool. He fills it with water to a depth of 5 feet. The water has a VOLUME of 1200 cubic feet.
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :
[tex]V=lbh[/tex]
Where
l and b are length and breadth
So,
[tex]lb=\dfrac{V}{h}\\\\lb=\dfrac{1200}{5}\\\\lb=240[/tex]
The first possibillity for dimension is (10×24). Another can be (12×20).

(the points O K and P are collinear )
(the points O B and A are collinear)
(KB) and (PA) are parallel
OK=X,OP=Y
KB=5
KP=6
and PA=8
CALCULATE THE LENGTH OP
Answer:
see in the picture, we have: y = 6 + x
=> x = y - 6
because KB//PA, using Thales Theorem, we have:
[tex] \frac{ok}{op} = \frac{kb}{pa} \\ \\ = > \frac{x}{y} = \frac{5}{8} \\ \\ < = > \frac{y - 6}{y} = \frac{5}{8} \\ \\ < = > 5y = 8(y - 6) \\ \\ < = > 5y = 8y - 48\\ \\ < = > 3y = 48 \\ \\ = > y = 16[/tex]
because OP = y => OP = 16

Bryan calculated the area of a square to be 18/32 square foot. Which shows the side length of the square? (Hint: Simplify. Also, area of a square is side x side.)
Answer:
x = 0.75 feet
Step-by-step explanation:
The area of a square is 18/32 square foot
We need to find the side length of the square.
The area of a square of side x is given by :
[tex]A=x^2[/tex]
Substitute all the values,
[tex]x=\sqrt{A} \\\\x=\sqrt{\dfrac{18}{32}} \\\\x=0.75\ feet[/tex]
So, the side length of the square is equal to 0.75 feet.

find the solution set of 5x+7> 17.
Answer:
x > 2
Step-by-step explanation:
5x +7 > 17
5x > 10
x > 2
Answer:
the solution of the Awnser is (x | x>2)
Step-by-step explanation:
Let's solve your inequality step-by-step.
5x+7>17
Step 1: Subtract 7 from both sides.
5x+7−7>17−7
5x>10
Step 2: Divide both sides by 5.
5x5>105
x>2
can some answer this math question
Answer:
A
Step-by-step explanation:
To multiply powers of a variable, add the exponents:
[tex]x^m\cdot x^n = x^{m+n}[/tex]
This rule works for all exponents, positive, negative, or zero. Also, remember that [tex]x^0=1[/tex].
Also, remember the definition of negative exponent: [tex]x^{-n} = \frac{1}{x^n}[/tex]
To multiply the two monomials, start by multiplying the coefficients, 14 and 4. That gives 56, so your answer begins with 56.
Now for the powers of x, [tex](x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}[/tex]
For the powers of y, [tex](y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1[/tex][tex](y^{-4})(y^4) = y^{-4+4} = y^0 =1[/tex]
Your answer is
[tex]56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}[/tex]
Write the slope and y-intercept of this linear equation: 3y + 6 = –2x
Answer:
slope = -2/3
y-intercept = -2
Step-by-step explanation:
3y + 6 = -2x
Conver to slope intercept form
3y = -2x - 6
y = -2/3x - 2
Follow the form y = mx + b, so m is the slope and b is the y-intercept
