If there is a bag of 3 blue cubes, 8 red cubes, and 4 yellow cubes and you drew from the bag 360 times, what is the probability of pulling a blue cube.
Answer:
After 360 attempts, there's a 100% probability of picking a blue cube.Step-by-step explanation:
There are 3 blue cubes, 8 ref cubes and 4 yellow cubes, which gives a total of 15 cubes.
Now, if you pick 360 times from the bag, the chances to get a blue cube is 100%, because there's only 15 cubes in total. For trial number 16, you wouldn't have any more cubes.
Therefore, after 360 attempts, there's a 100% probability of picking a blue cube.

find the relative minimum of y = 3x^3 + 12x^2 - 10x - 56
(___, __)
Round your answers to the nearest tenth
Answer:
(0.4, -57.9)
Step-by-step explanation:
y = 3x³ + 12x² - 10x - 56
dy/dx = 9x² + 24x - 10 = 0
x = [-24 +/- sqrt(24² - 4(9)(-10))]/(2×9)
x = -3.033006505, 0.3663398379
d²y/dx² = 18x + 24
For minima, d²y/dx² > 0 which is at x = 0.3663398379
y = 3(0.3663398379)³ + 12(0.3663398379)² - 10(0.3663398379) - 56
y = -57.90544608

Un garrafón de 6 litros tiene agua hasta ¾ de su capacidad, si se quieren vaciar esa cantidad de agua en recipientes más pequeños de 0.5 litros. ¿Cuántos recipientes se podrán llenar?
Answer:
9 recipientes
Step-by-step explanation:
Para empezar, tenemos que encontrar a cuánto equivalen 3/4 partes de 6 litros.
Para poder hacer esto, multiplicamos:
[tex](6)(\frac{3}{4})= \frac{18}{4} =\frac{9}{2}=4\frac{1}{2}[/tex]
Por lo tanto, el garrafón tiene 4.5 litros de agua.
Ahora, vamos a dividir esta agua en recipientes de 0.5 litros, por lo tanto, vamos a hacer una división:
4.5 ÷ 0.5 = 9
Por lo tanto, se van a poder llenar 9 recipientes.
Solve for p.
4p + 19 + 13p = –17 − p
Answer:
p=-2
Step-by-step explanation:
4p + 19 + 13p = –17 − p
4p+13p=17p
17p + 19 = -17 - p
18p=-36
p=-2
So the value of p is -2.

Use the information provided to write the equation of each circle. Photo attached
Answer:
( x + 4 )^2 + ( y - 15 )^2 = 1; Option A
Step-by-step explanation:
~ Let us apply the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2, provided r ⇒ radius when centered at point ( a, b ) ~
1. If the center is provided to be ( -4, 15 ) we could substitute this value into the circle equation with variables x and y remaining such:
( x - ( - 4 ) )^2 + ( y - 15)^2 = r^2
2. Simplifying this equation, we have: ( x + 4)^2 + ( y - 15 )^2 = r^2
3. Now by point on the circle, it would be a point on the circumference, to be clear in more mathematical terms. So far we have eliminated two options, with two remain - and each of them has either a radius of 1 or 2. If the point on the circle is ( -4, 16 ) that would mean 1 more than 15, which means that with a radius of 1 ⇒ this point will be on the circle.
Answer: ( x + 4 )^2 + ( y - 15 )^2 = 1

Does this statement: The number of girls is double than the number of boys , apply to this this equation : G=2B ,or the statement that I made is not correctly worded for that equation ???
•Would this statement be for that equation G=2B , : the number of boys is double the number of girls .
?? Someone help me I’ve been thinking about this and is making me bothersome.
Answer: It sounds as if you worded it correctly the first time, though for a math assignment, I probably wouldn't use the term "doubled" (though it is technically correct)
Step-by-step explanation:
G = 2B is "The total number of girls is two times the number of boys"
B = 2G is "The total number of boys is two times the number of girls"
Consider the equation x2 + y2 = 25, which is the equation of a circle. Explain what you might do in order to change this equation into the equation of each of the following:
an ellipse
a hyperbola
a parabola
What real-life objects or physical models of an ellipse, hyperbola, and parabola?
Answer:
1) You divide x measure by a2 and y measure by b^2 to equal 1 whole.
2) Using the vertices 0,0 we look for the negative (x-h^2)/ a2 and (y-k)^2/b^2
Which means distance from center to a vertices is 'a ' and means (hk)
3) So the parabola is a conic section (a section of a cone). Equations. x-squared is a parabola. The simplest equation for a parabola is y = x2. Most renowned is the given y = ax2 + bx + c
For graphs the difference from the given x2 equation is we keep double 'x' x2 to y and multiply h to 4p; we see (x - h)2 = 4p (y - k) usually focusing upright g k and p. Note below this focus changes from y to x if rotated on transversal.
Real life objects ;
Ellipses, including orbits of planets, satellites, moons and comets, and shapes of boat keels, rudders, and some airplane wings. A medical device called a lithotripter uses elliptical reflectors to break up kidney stones by generating sound waves.
Hyperbola;
Satellites, lenses radios, monitors Graphing a hyperbola shows this immediately: when the x-value is small, the y-value is large, and vice versa. Many real-life situations can be described by the hyperbola, including the relationship between the pressure and volume of a gas.
Parabolas; Are also used in satellite dishes to help reflect signals that then go to a receiver.From the paths of thrown baseballs, to fountains, this geometric shape is prevalent, and even functions to help focus light and radio waves.
Using Parabolic Reflectors to Focus Light
Flat surfaces scattered light too much to be useful to mariners. Spherical reflectors increased brightness, but could not give a powerful beam. But using a parabola-shaped reflector helped focus light into a beam that could be seen for long distances.
The idea that a parabolic reflector could produce an image was already well known before the invention of the reflecting telescope.
The name "parabola" is due to Apollonius, who discovered many properties of conic sections. It means "application", referring to "application of areas" concept, that has a connection with this curve.
Where the focus–directrix property of the parabola and other conic sections is due to Pappus of Alexandria. (c. 340) an encyclopedist where 8 volumes survived.
Galileo showed that the path of a projectile follows a parabola, a consequence of uniform acceleration due to gravity.
Step-by-step explanation:
The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1, represents an ellipse centered at the origin and with axes lying along the coordinate axes. In general, an ellipse may be centered at any point, or have axes not parallel to the coordinate axes.
The standard for a parabola is (x - h)2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.
Answer:
The answer is a parebola
Step-by-step explanation:
1) You divide x measure by a2 and y measure by b^2 to equal 1 whole.
2) Using the vertices 0,0 we look for the negative (x-h^2)/ a2 and (y-k)^2/b^2
Which means distance from center to a vertices is 'a ' and means (hk)

8(j-4)=2(4j-16)
Answer:
infinite solutions
Step-by-step explanation:
8(j-4)=2(4j-16)
Distribute
8j - 32 = 8j - 32
Subtract 8j from each side
8j-8j -32 = 8j-8j -32
-32 = -32
This is always true so there are infinite solutions
Answer:
All Real Numbers Are Solutions
Explanation:
8(j − 4) = 2(4j − 16)
[ Simplify both sides of the equation ]
8(j − 4) = 2(4j − 16)
(8)(j) + (8)(−4) = (2)(4j) + (2)(−16) (Distribute)
8j + −32 = 8j + −32
8j − 32 = 8j − 32
[ Subtract 8j from both sides ]
8j − 32 − 8j = 8j − 32 − 8j
−32 = −32
[ Add 32 to both sides ]
−32 + 32 = −32 + 32
0 = 0
Therefore, all real numbers are solutions.

An art collector bought 20 paintings at an art fair, and wants to know the average price of the paintings she purchased at the fair. She adds the prices of all the paintings and divides this number by 20 to find an average price of $350. Is this price
a sample mean or a population mean, and which symbol would be used to denote it
Answer:
population mean
Step-by-step explanation:
This price is a population mean, and symbol used to denote it is μ = ΣX/N.
What is mean?A mean in maths is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers.
Mathematically,
Mean = Sum of the observations/number of observations
Now it is given that,
average price of the paintings = $350
Number of paintings = 20
Now since the average is calculated by adding the prices of all the paintings and divides this number by 20.
Thus, it is a population mean denoted by the summation of X divided by the number of values in population which is denoted by Ν
⇒ μ = ΣX/N
Thus, this price is a population mean, and symbol used to denote it is μ = ΣX/N.

A rock was thrown from the top of a cliff such that its distance above sea level was given by s(t)= at² + bt + c, where t is the time in seconds after the rock was released. After 1 second the rock was 63 m above sea level, after 2 seconds 72 m, and after 7 seconds 27m.
Answer:
a) a = -3, b = 18, c = 48; s(t) = -3t²+18t+48b) 48mc) 8secsStep-by-step explanation:
The question is incomplete. Here is the complete question.
'A rock was thrown from the top of a cliff such that its distance above sea level was given by s(t)=at²+bt+c, where t is the time in seconds after the rock was released. After 1 second the rock was 63 m above sea level, after 2 seconds 72 m, and after 7 seconds 27 m. a. Find a, b and c and hence an expression for s(t). b. Find the height of the cliff. c. Find the time taken for the rock to reach sea level.'
Given the equation of the distance modelled as s(t)=at²+bt+c
If after 1 second the rock was 63 m, then 63 = a+b+c
If after 2 seconds, the distance was 72 m then 72 = 4a+2b+c
Also if after 7 seconds, the distance is 27 m, then 27 = 49a+7b+c
i) Solving the 3 equations simultaneously to get a, b and c we have;
a+b+c = 63 ... 1
4a+2b+c = 72 ...2
49a+7b+c = 27 ...3
Subtracting 2 from 1 and 3 from 2 we will generate 2 new equations as shown;
eqn 2- eqn1: 3a + b = 9...4
eqn 3- eqn 2: 45a + 5b = -45
eqn 3- eqn 2: 9a+b = -9 ... 5
solving 4 and 5 simultaneously
3a + b = 9 ...4
9a+b = -9 ... 5
Taking the difference of 4 and 5 we have
6a - -9-9
6a = -18
a = -3
substituting a = -3 into equation 4 to get b we have;
3(-3)+b = 9
-9 + b = 9
b = 9+9
b = 18
substituting a = -3 and b = 18 into equation 1 to get c we have;
-3+18+c = 63
15+c = 63
c = 48
a = -3, b= 18 and c = 48
The distance function will be s(t) = -3t²+18t+48
ii) If the height of the cliff is modelled by the equation s(t)=at²+bt+c
The height of the cliff is at when t = 0
s(0) = -3(0)²+18(0)+48
s(0) = 48m
The height of the cliff is 48m
iii) At the sea level, the height of the rock will be 0m, substituting this into the modeled equation for the height to get the time we have;
s(t)=at²+bt+c
0 = -3t²+18t+48
3t²-18t-48 = 0
t² - 6t - 16 =0
t² - 8t+2t - 16 = 0
t(t-8)+2(t-8) = 0
