The student body of a large university consists of 60% female students. A random sample of 8 students is selected. What is the probability that among the students in the sample at least 6 are female?
Using the binomial distribution, it is found that there is a 0.3154 = 31.54% probability that among the students in the sample at least 6 are female.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
The student body of a large university consists of 60% female students, hence p = 0.6.A random sample of 8 students is selected, hence n = 8.The probability that among the students in the sample at least 6 are female is given by:
[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{8,6}.(0.6)^{6}.(0.4)^{2} = 0.2090[/tex]
[tex]P(X = 7) = C_{8,7}.(0.6)^{7}.(0.4)^{1} = 0.0896[/tex]
[tex]P(X = 8) = C_{8,8}.(0.6)^{8}.(0.4)^{0} = 0.0168[/tex]
Then:
[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) = 0.2090 + 0.0896 + 0.0168 = 0.3154[/tex]
0.3154 = 31.54% probability that among the students in the sample at least 6 are female.

Write an equation for the orbit of Saturn in the form x^2/a^2 + y^2/b^2 = 1
*table is given showing Saturn has a semimajor axis (Gm) of 1472 and eccentricity of 0.0560
Answer:
x²/2166784 +y²/2159989 = 1
Step-by-step explanation:
The relationship between the semi-axes and the eccentricity of an ellipse is ...
e = √(1 -b²/a²)
In order to write the desired equation we need to find 'b' from 'e' and 'a'.
__
semi-minor axisSquaring the equation for eccentricity gives ...
e² = 1 -b²/a²
Solving for b², we have ...
b²/a² = 1 -e²
b² = a²(1 -e²)
ellipse equationUsing the given values, we find ...
b² = 1472²(1 -0.056²) = 2166784(0.996864) ≈ 2159989
The desired equation is ...
x²/2166784 +y²/2159989 = 1

What is the equation of the graph below? On a coordinate plane, a curve crosses the y-axis at y = 1. It has a maximum of 1 and a minimum of negative 1. It goes through 1 cycle at 5 pi. y = cosine (StartFraction x Over 0.4 EndFraction) y = cos(5x) y = cos(0.4x) y = cosine (StartFraction x Over 5 EndFraction)
The equation of the graph is given by y = cos(0.4x) and has an amplitude of 1
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Since the curve crosses the y-axis at y = 1, hence it is a cosine graph. It has a maximum of 1 and a minimum of negative 1, therefore the amplitude is 1
Also, the angular frequency = 2π * 1/5π = 0.4
The equation of the graph is given by y = cos(0.4x) and has an amplitude of 1

15ml of Tylenol 3 to given every 4-6 hours. Your research indicates that there are 12mg of codeine per 5ml of liquid and that the safe dosage is between 0.5 and 1mg/kg/every 4-6 hours. Is this prescription safe for your child? Explain. If not, what would a safe dose be?
Answer:
If the safe dose is .5 to 1 mg/kg/dose, the safe limit depends on the side of the child. Using the more conservative limit of .5mg/kg, you have 36mg(kg/.5mg)=72kg, which is roughly 160lbs, Even with the upper limit of 1mg/kg, you still have 36mg(kg/1mg) = 36kg, or 80lbs, which is a larger child. I would say this dose isn't "safe", but you really need the weight of the child to calculate what is a safe dose.

you have $5600. The best interest rate you can find is 3%
compounded quarterly, for how long should you deposit the money in order
have $9600? how many years
Answer:
18 years
Step-by-step explanation:
The formula for computing accrued amount A for a principal of P at an interest rate of r(in decimal) compounded n times in a year for t years is given by
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Note that r is percentage converted to decimal. So 3% = 3/100 = 0.03
We can rearrange the above equation to:
[tex]\frac{A}{P} = (1 + \frac{r}{n})^{nt}[/tex]
Taking logs on both sides
[tex]log(\frac{A}{P}) = log(1 + \frac{r}{n})^{nt}[/tex]
This gives
[tex]log(\frac{A}{P}) =nt \times log(1 + \frac{r}{n})\\So,\\nt = \frac{log(\frac{A}{P})}{ log(1 + \frac{r}{n})}[/tex]
In this particular problem, n = 4, , A= 9600, P = 5600, r =0.03, so r/n = 0.03/4 = 0.0075
1 + r/n = 1+0.0075 = 1.0075
4t = log(9600/5600)/log(1.0075) = log(1.714) / log(1.0075) = 0.234 /0.00325 = 72
t = 72/4 = 18 years

Given;Mariana is the youngest of four siblings.The sum of their ages is 86To Find;Mariana's age.Now, we know that their ages are consecutive integers.
Let their ages be (x), (x + 1), (x + 2) and (x + 3). Where, Mariana's age is x.
Here, The sum of their ages is 86.
(x) + (x + 1) + (x + 2) + (x + 3) = 86
x + x + 1 + x + 2 + x + 3 = 86
4x + 6 = 86
4x + 6 – 6 = 86 – 6
4x = 80
4x/4 = 80/4
x = 20
We assumed that Mariana's age is x and the value of x is 20.
Thus, The age of Mariana is 20.
