Three different views of identical cubes are shown at right. What is on the face
opposite the black cirde? Explain/Prove your enswer completely.
A cylinder is sliced at an angle, leaving the shape shown at right. The shorter height
is 12 cm while the longer height is 18 cm. The radius of the base is 4 cm.
What is the volume of this sliced cylinder?
1) The opposite face of the black circle is, Plus +.
2) The volume of the sliced cylinder is 96π cubic cm.
We have to given that;
Three different views of identical cubes are shown at right.
Now, From first and third dice,
Star is just opposite to symbol ~.
Hence, From second and third dice,
The opposite face of the black circle is, +
2) For the volume of the sliced cylinder, we need to first find the volume of the full cylinder and then subtract the volume of the smaller cylinder that's left after the slice is made.
Hence, The volume of the full cylinder is given by:
V = πr²h
Where r is the radius of the base and h is the height of the full cylinder.
Using the given values, we can find:
V = π(4²)(18)
V = 288π cubic cm
Now, let's find the volume of the smaller cylinder. The shorter height of 12 cm tells us that the slice removed 6 cm from the top of the cylinder. So the height of the smaller cylinder is,
18 - 6 = 12 cm.
The radius remains the same at 4 cm.
Thus, the volume of the smaller cylinder is:
V = π(4²)(12)
V = 192π cubic cm
Finally, we can find the volume of the sliced cylinder by subtracting the volume of the smaller cylinder from the volume of the full cylinder;
⇒ V = (288π) - (192π)
⇒ V = 96π cubic cm
Therefore, the volume of the sliced cylinder is 96π cubic cm.

The roots of the equation $2x^2-mx+n=0$ sum to $6$ and multiply to $10$. What is the value of $m+n$?
The value of m + n for the given quadratic equation is 8.
What is a quadratic equation?
A quadratic equation is a polynomial equation of the form:
[tex]ax^{2} +bx+c=0[/tex]
where x is the unknown variable, and a,b and c are constants. The highest power of the variable x in a quadratic equation is 2, hence the term "quadratic". The constants a,b and c are known as the coefficients of the quadratic equation.
According to the given information:
Let's denote the roots of the quadratic equation [tex]2x^{2} -mx+n=0[/tex] as r1 and r2, with r1 and r2 being the roots of the equation.
Given that the sum of the roots is 6 and the product of the roots is 10. This gives us the following equations:
r1 + r2 = 6 ------ (1)
r1*r2 = 10 ------- (2)
We can use these equations to solve for the values of m and n.
The sum of the roots r1 + r2 is also equal to [tex]\frac{-m}{2}[/tex] by Vieta's formulas, which state that the sum of the roots of a quadratic equation [tex]ax^{2} +bx+c=0[/tex] is given by [tex]\frac{-b}{a}[/tex]. Therefore, we can write:
[tex]\frac{-m}{2}[/tex] = 6
Solving for m, we get:
m = -2*6 = -12 ----------(3)
The product of the roots r1*r2 is also equal to n/2 by Vieta's formulas, which states that the product of the roots of a quadratic equation [tex]ax^{2} +bx+c=0\\[/tex] is given by [tex]\frac{c}{a}[/tex]. Therefore, we can write:
n/2 = 10
Solving for n, we get:
n = 2 * 10 = 20 ------------(4)
Now, we can find the value of m+n by substituting the values of m and n from equations (3) and (4) respectively:
m + n = -12 + 20 = 8
So, the value of m+n is 8.

The equation of the function g(x) is g(x) = f(x+3) + 4 and g(x) = log₂(x+3) + 4
State g(x) in terms of f(x)To shift the function 3 units left, we replace x with x+3. To shift it 4 units up, we add 4 to the function.
Therefore, the expression for g(x) in terms of f(x) is:
g(x) = f(x+3) + 4
Determine equation of the function g(x)Substituting f(x) = log₂(x), we get:
g(x) = log₂(x+3) + 4
The equation of the function g(x) is g(x) = log₂(x+3) + 4.
State the domain, range, asymptotes of g(x)The domain of g(x) is all x such that x+3 > 0, since the argument of the logarithm must be positive. This gives x > -3.
The range of g(x) is all real numbers, since the logarithm takes on all real values.
The vertical asymptote is x = -3, since this is where the function becomes undefined (the argument of the logarithm becomes 0).

How many possible winning number combinations a bettor may opt to select in a 6/42 Lottery? And based on this, what is the probability a bettor may win the lottery jackpot prize?
There are 5,245,786 possible winning number combinations in a 6/42 lottery, and for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.
What is the combinations?
Combinations refer to the different ways of selecting a subset of items from a larger set without regard to the order in which the items are selected. In other words, combinations are the different ways of choosing a group of items without taking into account their arrangement or order.
In a 6/42 lottery, there are 6 numbers drawn from a pool of 42 numbers. To determine the number of possible winning number combinations, we can use the formula for combinations:
C(n,r) = n! / (r! * (n-r)!)
where n is the total number of items in the set and r is the number of items being chosen.
In this case, we have 42 numbers in the pool and we need to choose 6 numbers, so the formula becomes:
C(42,6) = 42! / (6! * (42-6)!)
which simplifies to:
C(42,6) = 5,245,786
Therefore, there are 5,245,786 possible winning number combinations in a 6/42 lottery.
To calculate the probability of winning the jackpot prize, we need to divide the number of ways to win by the total number of possible outcomes. Since there is only one winning combination, the probability of winning the jackpot is:
1 / 5,245,786
which simplifies to approximately:
0.000019% or 1 in 5,245,786.
This means that for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.
hence, there are 5,245,786 possible winning number combinations in a 6/42 lottery, and for every ticket purchased, there is a 1 in 5,245,786 chance of winning the jackpot prize.

17,199 children.
b. Using the unrounded mean from part (a), find the probability that the number of tumor cases in a group of
17.199 children is 0 or 1.
c. What is the probability of more than one case?
d. Does the cluster of four cases appear to be attributable to random chance? Why or why not?
a) The mean number of cases in groups of 17,199 children is 0.187.
b) The probability of 0 or 1 case in a group of 17,199 children is 0.832.
c) The probability of more than one case in a group of 17,199 children is 0.168.
d) The expected number of cases is 3.214 and the actual number of cases is 4
What is the probability?Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.
For example, if you flip a fair coin, the probability of it landing heads up is 0.5, because there are two equally likely outcomes (heads and tails), and one of them is heads. Similarly, if you roll a fair six-sided die, the probability of rolling a 3 is 1/6, because there are six equally likely outcomes (rolling a 1, 2, 3, 4, 5, or 6), and only one of them is a 3.
According to the given informationa. Assuming that the tumor occurs as usual, the mean number of cases in groups of 17,199 children can be calculated as:
mean = (probability of a single case) x (number of children) = 0.000011 x 17,199 = 0.187
So the mean number of cases in groups of 17,199 children is 0.187.
b. The probability of 0 or 1 case can be found using the Poisson distribution, which models the probability of a certain number of events occurring in a fixed interval of time or space, given the mean rate of occurrence. In this case, the Poisson distribution can be used to find the probability of 0 or 1 case in a group of 17,199 children, given the mean of 0.187.
The probability of 0 or 1 case can be calculated as follows:
P(0 or 1 case) = P(0 case) + P(1 case)
= (e⁽⁻⁰°¹⁸⁷⁾ * 0.187⁰) / 0! + (e⁽⁻⁰°¹⁸⁷⁾ * 0.187¹) / 1!
= 0.832
Therefore, the probability of 0 or 1 case in a group of 17,199 children is 0.832.
c. The probability of more than one case can be found as:
P(more than one case) = 1 - P(0 or 1 case)
= 1 - 0.832
= 0.168
Therefore, the probability of more than one case in a group of 17,199 children is 0.168.
d. To determine whether the cluster of four cases is attributable to random chance, we can compare the actual number of cases with the expected number of cases based on the mean rate of occurrence.
The expected number of cases in a group of 17,199 children can be found by multiplying the mean rate of occurrence (0.187) by the number of groups:
expected number of cases = 0.187 x 17199 = 3.214
Since the expected number of cases is 3.214 and the actual number of cases is 4.

If the probability that a randomly chosen college student takes statistics is 0.24, then what is the probability that a randomly chosen college student does not take statistics? Give your answer as a decimal.
Answer:
The probability that a randomly chosen college student does not take statistics is 0.76.
Step-by-step explanation:
The probability of an event happening and the probability of its complement (the event not happening) must add up to 1. Therefore, if the probability that a randomly chosen college student takes statistics is 0.24, then the probability that they do not take statistics is:
1 - 0.24 = 0.76
So the probability that a randomly chosen college student does not take statistics is 0.76 or 76%.

The equation StartFraction 1 over 8 EndFraction (x + 16) = 76 represents the situation, where x is the food bill. The solution x = 60 represents the total food bill. The solution x = 60 represents each friend’s share of the food bill and tip. The equation 8 (x + 16) = 76 represents the situation, where x is the food bill.
An equation and solution that describe the situation is: B. The equation 1/8(x + 16) = 76 represents the situation, where x is the food bill.
How to write an equation to model this situation?In order to write a linear equation to describe this situation, we would a assign variable to the food bill, and then translate the word problem into a linear equation as follows:
Let the variable x represent the total amount of the food bill.
Since this group of 8 friends spent a total of $76, which included the food bill and a tip of $16, and decided to split the bill and tip evenly among themselves, a linear equation that can be used to model this situation is given by;
1/8(x + 16) = 76
(x + 16) = 76(8)
x + 16 = 608
x = 608 - 16
x = $592.

Answer:
0
Step-by-step explanation:
If we have the function f(x)=sqrt((x-8)/3), where 8 is less than or equal to x which is less than or equal to 16, we can evaluate f(8) as follows:
f(8)=sqrt((8-8)/3)
=sqrt(0/3)
=0

Exercise 6.2.8: Solve ′′′ + = 3( − 1) for initial conditions (0) = 1 and ′(0) = 0, ′′(0) = 0.
Answer:
Step-by-step explanation:
To solve the differential equation:
y′′′ + y = 3(y′ − 1)
we first find the characteristic equation:
r^3 + 1 = 0
The roots of this equation are:
r = -1, 0 ± i
So, the general solution of the homogeneous equation (y′′′ + y = 0) is:
y_h(t) = c1 e^(-t) + c2 cos(t) + c3 sin(t)
To find a particular solution of the non-homogeneous equation (3(y′ − 1)), we assume a solution of the form:
y_p(t) = a t + b
Taking the first, second and third derivatives of y_p(t), we get:
y′_p(t) = a
y′′_p(t) = 0
y′′′_p(t) = 0
Substituting these into the differential equation, we get:
0 + (a t + b) = 3(a - 1)
Solving for a and b, we get:
a = 1
b = 2
Therefore, the particular solution of the non-homogeneous equation is:
y_p(t) = t + 2
So, the general solution of the non-homogeneous equation is:
y(t) = y_h(t) + y_p(t) = c1 e^(-t) + c2 cos(t) + c3 sin(t) + t + 2
To find the values of c1, c2 and c3, we use the initial conditions:
y(0) = c1 + c2 + 2 = 1
y′(0) = -c1 + c2 + c3 = 0
y′′(0) = c1 - c2 = 0
Solving these equations simultaneously, we get:
c1 = c2 = 1/2
c3 = -1/2
So, the solution of the differential equation with initial conditions (0) = 1, ′(0) = 0, ′′(0) = 0 is:
y(t) = 1/2 e^(-t) + 1/2 cos(t) - 1/2 sin(t) + t + 2
