If five standard (six-sided) dice are tossed onto the table, what is the probability that
a. all of them will show an odd number on top?
b. no aces or deuces (that means ones or twos) will show on top?
C. the five dice will show five different values on top?
If Five standard (six-sided) dice are rolled, one at a time. What is the probability that
a. the first two dice show aces, and the next three do not?
b. two of the five dice show aces, and the other three do not?
The probability of getting a specific number on the first roll of the die is 1/6. The probability of getting that same number on five successive rolls is (1/6)^5 = 1/7776. Because there are six different ways to get the same number on five rolls, multiply by 6 to get the probability of the same number on five successive rolls to be 6/7776 =1/1296.
Determining the probability that all five rolls will be different starts with asking how many ways can you choose 5 numbers from six with replacement and without repetition where order does not matter, then dividing that number by the total number of outcomes in five rolls of the die.
The total number of possible rolls is easy. There are six possible outcomes for each of the five rolls, so the total number of possible combinations after 5 rolls is 6^5 = 7776.
Now if each roll has to be a different number, consider that there are six acceptable outcomes on the first roll of the die. There are only five acceptable outcomes on the second roll, four on the third, three on the fourth, and two on the fifth. Multiplying all these together gives 6x5x4x3x2 = 6! = 720 ways to get a different number on five successive rolls of the die. This probability is 720/7776 ( 0.0926 or 9.26% or 120 times greater than getting the same number on each of five rolls.
Consider a game in which six true dice are rolled. What is the probability of obtaining exactly one ace, at least one ace and exactly two aces?
Exactly 1 ace(one) =6C1 * 5^5 = 18750 / 6^6 = 0.401877572
At Least 1 ace(one) =6C1 *5^5 +6C2 * 5^4 + 6C3 * 5^3......6C6 * 5^0= 31031/6^6 = 0.6651020233
Exactly 2 aces(ones) =6C2 * 5^4 = 9375 / 6^6 = 0.200938786
If you require two specific times(e.g. first time and second time) to be 5(probability 1/6), others to be non-5(probability 1−1/6=5/6). The probabiliy is (1/6)2(5/6)3, you have C52=10 different ways to roll two 5. Therefore the answer is 10(1/6)2(5/6)3, which is approximately 0.1608.

1,440,000
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{7 cm}\underline{General form of an Exponential Function}\\\\$y=Ae^{kt}$\\\\where:\\\phantom{ww}$\bullet$ $A$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $k$ is a constant.\\ \phantom{ww}$\bullet$ $t$ is time.\\\end{minipage}}[/tex]
Given:
Doubling period = 15 minutesAt t = 120 minutes, y = 90,000(Let t = time in minutes).
If the doubling period is 15 minutes, then at t = 135 minutes, y = 180,000:
[tex]\implies 90000=Ae^{120k}[/tex]
[tex]\implies 180000=Ae^{135k}[/tex]
Divide the second equation by the first to eliminate A, and solve for k:
[tex]\implies \dfrac{180000}{90000}=\dfrac{Ae^{135k}}{Ae^{120k}}[/tex]
[tex]\implies 2=\dfrac{e^{135k}}{e^{120k}}[/tex]
[tex]\implies 2=e^{135k} \cdot e^{-120k}[/tex]
[tex]\implies 2=e^{15k}[/tex]
[tex]\implies \ln 2 = \ln e^{15k}[/tex]
[tex]\implies \ln 2 =15k \ln e[/tex]
[tex]\implies \ln 2 =15k[/tex]
[tex]\implies k=\dfrac{1}{15}\ln 2[/tex]
Substitute t = 120, y = 90000 and the found value of k into the formula and solve for A:
[tex]\implies 90000=Ae^{\left(120 \cdot \frac{1}{15}\ln 2\right)}[/tex]
[tex]\implies 90000=Ae^{\left(8\ln 2\right)}[/tex]
[tex]\implies 90000=Ae^{\ln256}[/tex]
[tex]\implies 90000=256A[/tex]
[tex]\implies A=\dfrac{90000}{256}[/tex]
[tex]\implies A=351.5625[/tex]
Therefore, the function that models the scenario is:
[tex]\large\boxed{y=351.5625e^{\left(\frac{1}{15}t \ln 2\right)}}[/tex]
So the initial population at time t = 0 was:
351.5625To find the size of the bacteria population after 3 hours, substitute t = 180 into the found formula:
[tex]\implies y=351.5625e^{\left(\frac{1}{15}(180) \ln 2\right)}[/tex]
[tex]\implies y=351.5625e^{\left(12 \ln 2\right)}[/tex]
[tex]\implies y=351.5625e^{\left(\ln 4096\right)}[/tex]
[tex]\implies y=351.5625 \cdot 4096[/tex]
[tex]\implies y=1440000[/tex]
Therefore, the size of the bacterial population after 3 hours was:
1,440,000The initial population at the time t = 0 is 351.5625. And the size of the bacterial population after 3 hours is 1,440,000.
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
If n₀ is the initial size of a population experiencing exponential growth, then the population n(t) at time t is modeled by the function:
n(t) = n₀(e[tex])^{rt}[/tex]
Where r is the relative rate of growth expressed as a fraction of the population.
Given:
Doubling period = 15 minutes
At t = 120 minutes, n(t) = 90,000
If the doubling period is 15 minutes, then at t = 120+15 = 135 minutes,
90000 = n₀(e[tex])^{120r}[/tex]
18000 = n₀(e[tex])^{135r}[/tex]]
To find the r:
Take ratio of both of the equations,
90000 / 18000 = n₀(e[tex])^{120r}[/tex] / n₀(e[tex])^{135r}[/tex]
2 = (e[tex])^{135r}[/tex] . (e[tex])^{-120r}[/tex]
r = 1/15 ln2
Substitute the value of r, t and y.
90000 = n₀(e[tex])^{120r}[/tex]
90000 = 256n₀
n₀ = 351.5652
Now, the function
n(t) = n₀(e[tex])^{rt}[/tex]
n(t) = (351.5652)(e[tex])^{(1/15)(180)(ln2)}[/tex]
n(t) = 1440000
Therefore, the initial population at the time t = 0 is 351.5625. And the size of the bacterial population after 3 hours is 1,440,000.

If x)=x+7 and 9(x)=x-13.
The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).
So, {x|x≠13} option 4 is correct.
What is meant by domain?A function's domain is the collection of all potential inputs. For instance, all real numbers are in the domain of f(x)=x², and all real numbers are in the domain of g(x)=1/x, with the exception of x=0.
Let y = f(x) be a function where x and y are the independent and dependent variables. If a function f offers a means of successfully generating a single value y while using a value for x to that end, then that selected x-value is said to belong to the domain of f.
The result of multiplying the expression for f(x) by the expression for g(x) is (x + 7)(1/x-13).
This can be expressed much more clearly as (x + 7) (x – 13)
All real numbers, with the exception of 13, can be used to replace x in the expression in this condensed form. This is due to the fact that if we substitute 13 for x, our denominator will be equal to 0, making our formula illogical.
The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).

Answer:
$4.50
Step-by-step explanation:
Use a proportion:
$6.75 is to 3 bags as x is to 2 bags.
6.75/3 = x/2
3x = 2 × 6.75
x = 4.50

Answer:
$4.50
Step-by-step explanation:
Given 3 bags of cat food cost $6.75, you want the cost of 2 bags.
ProportionUnless there is a volume discount (or surcharge), the price is proportional to the quantity. That means 2 bags will cost 2/3 the amount that 3 bags cost.
cost of 2 bags = 2/3 · $6.75 = $4.50

A taxi service charges $1.50 plus $0.60 per mile for a trip to the airport. The total charge is $13.50. Determine how many miles it is to the airport.
Using the linear function y = 0.6x + 1.5, he drove 20 miles to be charged $13.50
Linear FunctionThe parent linear function is f(x) = x, which is a line passing through the origin. In general, a linear function equation is f(x) = mx + c
where m is the slope of the equation and c is the y - intercept.
To solve this problem, we have to write an equation that models y = mx + c
c = constant = service charge = 1.50m = slope = 0.60The linear function to model this is given as;
y = 0.6x + 1.5
Assuming a trip cost 13.50, the number of miles can be calculated as;
13.50 = 0.6x + 1.5
0.6x = 13.50 - 1.5
0.6x = 12
x = 12/0.6
x = 20
The drove 20 miles

Solve for pressure #2 using Bernoullis equation
What is the definition of Bernoulli's principle?
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.
p+12ρ v2+ρgh=konstant Bernoulli equation(1)
Two states on a streamline are thus linked by the following equation:
p1+12ρv21+ρgh1=p2+12ρv22+ρgh2p1+12ρv21=p2+12ρv22p2=p1+12ρv21−12ρv2
Due to the constriction of the cross-section to only half the size, the flow speed is doubled. All known values can now be put in equation (5). Note that the pressure is to be used in the basic unit N/m² and the density in the unit kg/m³.
p2=p1+12ρv21−12ρv22p2=4⋅105Nm²+121000kgm³ (4ms)2–121000kgm³ (8ms)2=3.76⋅105Nm²p2=3.76 bar

1/4 + 29/16 - 9735/12
Answer:
Step-by-step explanation:
To solve this problem, we need to add and subtract the fractions given. To do this, we need to find a common denominator for all of the fractions.
The least common multiple of 4, 16, and 12 is 48, so we can rewrite each fraction with a denominator of 48:
1/4 = 3/12
29/16 = 87/48
9735/12 = 4047/48
Then, we can add and subtract the fractions as follows:
3/12 + 87/48 - 4047/48 = (3 - 4047)/48 = -4044/48 = -84/16
Therefore, the final answer is -84/16, or -5 and 1/16 in simplified form.
Myra is taking her first hot-air balloon ride! The balloon was at an altitude of 288 meters until an air current caused it to rise another 36 meters.
What is the altitude of the balloon now?
The altitude of the balloon now is 324 meters
How to determine the altitude of the balloon now?From the question, we have the following parameters that can be used in our computation:
Initial altitude = 288 meters
Rise = 36 meters
The altitude of the balloon now is calculated as
Current altitude = Initial altitude + Rise in altitude
Substitute the known values in the above equation, so, we have the following representation
Current altitude = 288 + 36
