The probability of all three events happening when the dies are rolled is; 0.0083
What is the Probability of Rolling a Die?A) On the first die, it has 6 sides and 3 must come out, that is, 1 event out of 6 possible, therefore the probability is: 1/6
B) On the second die, it has 20 sides and if 19 or 20 can come out, that is 2 events out of 20 possible, so the probability is: 2/20 = 1/10
C) On the third die, which is 12 sides, an odd number can come out. The odd numbers would be 1, 3, 5, 7, 9, 11; i.e, 6 events out of 12 possible numbers.
Thus, the probability would be: 6/12 = 1/2
The final probability would be;
(1/6) * (1/10) * (1/2) = 0.0083

a) The probability of a head exists at 0.7.
b) He could improve his experiment by doing more coin flips.
What is probability?Probability signifies possibility. It exists a branch of mathematics that values the event of a random event. The value exists represented from zero to one.
Given: Coin flipped 10 times.
The Head comes T times and the tail comes 7 times.
To estimate the probability of head in the outcome.
The total number of outcomes is 10 and the head comes 7 times.
a) Probability(head) = 7/10 = 0.7
The probability of a head exists at 0.7.

scientist released 8 rabbits into a new habitat in year 0. Each year, there were twice as many rabbits as the year before. How many rabbits were there after X years? Write a function to represent this scenario.
Answer:
Step-by-step explanation:
his function will be an exponential function, because the number of rabbits double each year
the basic form for exponential functions is
where s is the starting number, c i s the constant (rate of change like double, triple, etc.) and x is the number repeats (in this case, years)
so in this case, the starting number (year 0) is 8, and the rate of change is 2
therefore, the equation is:

what is the average rate of change for this function for the interval from x = 1 to x = 3?
a. 4 b. 2 c. 3 d. 8
The average rate of change for this function for the interval from x = 1 to x = 3 is 3
How to determine the average rate of change?The average rate of change is calculated as:
m = (f(b)- f(a))/(b - a)
The interval is given as:
x = 1 to x = 3
From the table of values, we have:
f(1) = 7
f(3) = 13
So, we have:
m = (13-7)/(3-1)

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.
¿Cuántos dias tardarán en fabricar 3000 ruedas si trabajan 10 horas diarias?Sabemos que trabajando 8 horas, en 5 dias producen 2000 ruedas.
El número total de horas que trabajan en esos 5 dias es:
(8 horas)*5 = 40 horas
Entonces se producen 2000 ruedas en 40 horas, es decir, la razon de trabajo es:
(2000 ruedas)/(40 horas) = 50 ruedas por hora.
Ahora, sí en la fabrica trabajan 10 horas al día, entonces van a producir:
10h*(50 ruedas por hora) = 500 ruedas por día.
El número x de días que deben trabajar para producir 3000 ruedas es:

Compute the monthly payments for the add on interest loan. The amount of the loan is $8,276.17. The annual interest rate is 5.7%. The term of the loan is 5.5 years.
The monthly payments for this add on interest loan are of $164.71.
Given Information and Formula Used
It is given that for an add on interest loan,
Principal Amount, p = $8,276.17
Annual Interest Rate, r = 5.7%
Term of the loan, T = 5.5 years
The formula for simple interest is given as follows,
I = (p)(r)(t)/100 ............... (1)
The formula for total amount of add on interest is given by,
A = p + I ....................... (2)
Computing the Interest
Substitute the given values of p, r, and t in the formula (1) of interest to get,
I = (8276.17)(5.7)(5.5)/100
I = 259457.9295/100
I = $2,594.58
Computing the Monthly Payment for Add-on Interest Loan
Substituting the values of p and I in the formula (2), we obtain the total amount as,
A = $ (8276.17 + 2594.58)
A = $ 10,870.75
Monthly payment for the add on interest loan = A/t(in months)
= $ (10,870.75/66)
= $164.71
Therefore, monthly payments of $164.71 are to be made for the add on interest loan.

A zoo has a black rhinoceros that weighs 18 times as much as an average-size chimpanzee. The rhinoceros weighs 2,250 pounds.
How much does an average-size chimpanzee weigh?
Enter the answer in the box. [_]
Answer: 125 pounds
Step-by-step explanation:
Let's first represent the weight of the black rhinoceros and chimpanzee with variables. We will assign r for the rhinoceros and c for the chimpanzee.
In the question, we were given that the weight for a black rhinoceros is 18 times as much as an average-size chimpanzee. This makes 18 times the chimpanzee's weight equal to the rhinoceros' weight.
Let's put this into an equation.
[tex]r=18*c[/tex]
Now, let's put in the values we know to find the weight of the chimpanzee (i.e., c). We know the weight of a rhinoceros (represented by r) is 2250 pounds, so we can replace it for r in the equation.
[tex]2250=18*c[/tex]
To solve this equation, we can divide both sides by 18 to get c by itself and know what it's value is.
[tex]\frac{2250}{18}=\frac{18*c}{18}[/tex]
We can remove the [tex]\frac{18}{18}[/tex] from the right side to be left with c. We can also divide 2250 by 8 to get the weight of an average-size chimpanzee.
[tex]c=\frac{2250}{18}\\ c=125[/tex]
Hence, an average-size chimpanzee weighs 125 pounds.
