We have given that,
The given procedure results in a binomial distribution. If not, state the reason why. Choosing 5 people (without replacement) from a group of 58 people, of which 15 are women, keeping track of the number of men chosen.
What is the Binomial distribution?In samples with replacement, the probability has to be the same for each trial, that is, they are independent.
Hypergeometric distribution
Samples without replacement, as the probabilities depend on the previous outcomes, that is, they are not independent.
In this question
Marbles are chosen without replacement, which means that for each trial the probabilities of choosing a red marble are different, which means that the trials are not independent. So the answer is:
Not binomial the trials are not independent.

(b) Express the radius r as a function of x.
(c) Express the height has a function of x.
(d) Express the volume V of the cone as a function of x.
pls helpppp
The circumference of the base of the cone is 8π - x since the base is equal to go the arc length of the remainder of the circle.
How to calculate the values?The radius r as a function of x will be:
8π - x = 2πr
r = (8π - x)/2π
r = 4 - x/2π
The height has a function of x will be:
r² + h² = 16
h² = 16 - r²
where r = 4 - x/2π
h = √16 - ✓(4 - x/2π)²
h = 4✓(4 - x/2π)²
The volume V of the cone as a function of x will be:

the interest paid for borrowing qn amount of money for 3yrs at the rate of 4%is n108 find the amount of the money borrowed
Answer:
$864.94
Step-by-step explanation:
So the amount of money over time can be given with an exponential function y=a(b)^x or more specifically y=a(1+r)^x where r is the growth rate (interest rate)
So the equation can be written as
[tex]m= P(1.04)^t[/tex] where m represents the amount of money over time, P represents the principle amount, and t represents time in years. Since we're given the amount of interest paid and not the total amount which includes the initial amount borrowed you have to subtract P from the equation. This will give us the equation that we'll use to find the initial amount
[tex]I = P(1.04)^t-P[/tex] where I represents the interest paid.
plug the values into the equation
[tex]108 = P(1.04)^3-P\\108 = P(1.124864) - P\\108 = 0.124864P\\\\864.941 = P[/tex]

One of the five quadratics below has a repeated root. (The other four have distinct roots.) What is the repeated root?
$\begin{align*}
&-x^2 + 18x + 81 \\
&3x^2 - 6x + 9 \\
&8x^2 - 32x + 32 \\
&25x^2 - 30x - 9 \\
&x^2 - 14x + 196
\end{align*}$
Answer:
Step-by-step explanation:
The quadratic expression having repeated root is 8x² - 32x + 32.
What are Quadratic Expressions?Quadratic expressions are polynomial expressions of second degree.
The general form of a quadratic expression is ax² + b x + c.
We have to find the root of each quadratic expression.
-x² + 18x + 81 = 0x² - 18x - 81 = 0
Discriminant = [tex]\sqrt{(-18)^2-(4*-81)}[/tex] = [tex]\sqrt{648}[/tex]
x = (18 + √648) / 2 or x = (18 - √648) / 2
Distinct roots
3x² - 6x + 9x² - 2x + 3
Discriminant = [tex]\sqrt{(-2)^{2}-(4*3) }[/tex] = [tex]\sqrt{-8}[/tex]
x = (2 + [tex]\sqrt{-8}[/tex]) / 2 or x = (2 - [tex]\sqrt{-8}[/tex]) / 2
Distinct roots
8x² - 32x + 32
x² - 4x + 4Discriminant = [tex]\sqrt{(-4)^{2}-(4*4) }[/tex] = 0
x = (4 + 0)/ 2 or x = (4 - 0) / 2
x = 2 or x = 2
Repeated roots
Hence the quadratic expression having repeated roots is 8x² - 32x + 32.

Sometimes, a data set has two values that have the highest and equal frequencies. In this case, the distribution of the data can best be described as
A data set having two values that have the highest and equal frequencies will have a bimodal distribution. Hence, option D is the right choice.
A symmetric distribution occurs when the mean, median, and mode all occur at the same location and the values of the variables occur at regular intervals.The few low scores in a negatively skewed distribution tend to push the mean to the left, thus the mean is typically lower than the median.The mode is consistently less than the mean and median in a positively skewed distribution.A continuous probability distribution having two distinct modes, that is, two separate values with the highest and equal frequencies is referred to as a bimodal distribution.Thus, a data set having two values that have the highest and equal frequencies will have a bimodal distribution. Hence, option D is the right choice.

According to the given synthetic division, the statements that are true are; Options A, C and E
How to carry out Synthetic Division?
In the synthetic calculation we use the coefficient of the dividend
with the factors of the function.
Therefore;
3 , -13 , 4 are the coefficient of the dividend 3x² - 13x + 4
Therefore, the divisor is 4 and as such x = 4 is a root of f(x) = 3x² - 13x + 4
Also, it means that (x - 4) is a factor of the dividend F(x) = 2x² - 2x - 12
- The quotient is the last line of the synthetic division. Thus, the coefficients of quotient are 3, -1.
- The quotient is 1 degree less than the dividend and so the degree of the dividend is 2.
- The degree of the quotient is 1 and so the he quotient is 3x - 1.
