The Mann-Whitney U test is not appropriate for a comparison of two means in a causal comparative study.

To determine if two samples are likely to come from the same population, researchers employ the Mann Whitney U test, also known as the Mann Whitney Wilcoxon Test or the Wilcoxon Rank Sum Test (i.e., that the two populations have the same shape). When a continuous level variable is measured across all observations in two groups and we wish to test if the distribution of this variable differs between the two groups but we are unable to assume normality in both groups, we use the Mann-Whitney test.

After 25 years, about 52g of the sample will be left and the sample never reaches half of its original amount

From the question, we have the following parameters that can be used in our computation:

A(t)= 200е⁻⁰⁰⁵⁴⁺

Also from the question, we have

The variable t represents the number of years

This means that

t = 25, in this case

So, we have

A(25)= 200е⁻⁰⁰⁵⁴ ˣ ²⁵

Evaluate the above equation

A(25)= 51.848052128

Approximate

A(25) = 52

This means that the remaining sample is 52 grams

Here, we have

A(t) = 0.5 * 200

A(t) = 100

Substitute the known values in the above equation, so, we have the following representation

200е⁻⁰⁰⁵⁴⁺ = 100

Divide both sides by 100

е⁻⁰⁰⁵⁴⁺ = 0.5

Take the natural logarithm of both sides

0.054t = -0.69314718056

So, we have

t = -0.69314718056/0.054

Evaluate

t = -13

------------------------

Explanation:

The goal is to factor the radicand in such a way that we pull out perfect cube factors.

Notice that 200 = 8*25 and 8 is a perfect cube (since 2^3 = 8). It is the largest perfect cube factor of 200.

We can rewrite the k^15 as k^(5*3) which is equivalent to (k^5)^3

Once these perfect cube factors are pulled out, they cancel with the cube root to get what you see above.

Hello,

I hope you and your family are doing well!

The answer is y = 5 (See below for the explanation).

To find a linear equation representing a line passing through two points, you can use the slope-intercept form of the equation, which is written as y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

To find the slope of the line, you can use the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of the two given points, we get:

m = (5 - 5) / (-8 - 3) = 0 / -11 = 0

Since the slope of the line is 0, the line is horizontal and passes through both points at the same y-value (5). The x-intercept (the point at which the line crosses the x-axis) is not relevant in this case.

Therefore, the linear equation representing this line is y = 5.

A polynomial function of least degree with rational coefficients so that P(x) = 0 has the given roots is P(x)=x²-5x-14

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. One polynomial with an exponent of 1 is 2x+5, for instance. One that has more than two algebraic terms is referred to as a polynomial expression. Polynomial is a monomial or binomial that is repeatedly added, as the name suggests.

A mathematical expression containing one or more algebraic terms, where each algebraic term is made up of a constant multiplied by one or more variables raised to a nonnegative integral power.

x= -2, x=7

Given,

P(x) = 0

This polynomial function has the roots,

x= -2, x=7

So,

(x+2)(x-7)

We have to multiply both of them we get,

P(x)=(x+2)(x-7)

0=x²-5x-14

x²-5x-14=0

Therefore, P(x)=x²-5x-14 is the polynomial function.

Answer:

To earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67. The formula for calculating simple interest is I = P * R * T, where I is the interest earned, P is the principal amount invested, R is the interest rate, and T is the time in years. In this case, we are given that the interest rate is 3%, the time is 16 months, and the interest earned is $65, so we can plug these values into the formula to solve for the principal amount invested:I = P * R * T

$65 = P * 0.03 * (16/12)

$65 = P * 0.03 * (4/3)

$65 = P * 0.01

P = $2,166.67Therefore, to earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67.

The x- and y-coordinates of point C, which partitions the directed line segment from A to B into the ratio 3:10 are (-2.6,5.2).

A line segment in geometry has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction. A ray has only one endpoint and an endlessly long another end, as opposed to a line segment that has two ends.

If a point (x,y) divides the line segment joining the points A(x1,y1) and B (x2,y2) is in the ratio m:n, then

[tex]x=\frac{mx2+nx1}{m+n} \\y=\frac{my2+ny1}{m+n} \\[/tex]

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Thus, after 25 years, there will be

The ratio of the volume of the second cylinder to the volume of the first cylinder is 25.

To find the ratio of the volume of the second cylinder to the volume of the first cylinder, we need to calculate the volumes of both cylinders and then compare them.

The formula to calculate the volume of a right circular cylinder is given by V = πr^2h, where V represents the volume, r is the radius, and h is the height.

For the first cylinder:

Radius (r₁) = 3 centimeters

Height (h₁) = 5 centimeters

Volume of the first cylinder (V₁) = π * (3 cm)^2 * 5 cm

                             = 45π cm³

For the second cylinder:

Radius (r₂) = 15 centimeters

Height (h₂) = 5 centimeters

Volume of the second cylinder (V₂) = π * (15 cm)^2 * 5 cm

                              = 1125π cm³

To find the ratio of the volumes, we divide the volume of the second cylinder by the volume of the first cylinder:

Ratio = V₂ / V₁

     = (1125π cm³) / (45π cm³)

     = 25

Therefore, the ratio of the volume of the second cylinder to the volume of the first cylinder is 25.

The probability of not pulling hip hop CDs is equal to 3/5. The correct option is (A).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

Given that,

The number of country, rock, hip hop, and jazz CDs are 10, 5, 12 and 3 respectively.

Then, the total number of CDs are 10 + 5 + 12 + 3 = 30

Now, the probability of not selecting hip hop is equal to the probability of selecting the remaining types of CDs which is given as,

P(Not hip hop CDs) = (10 + 5 + 3)/30    

                                 = 18/30

The equation that represents a line, in slope-intercept form, is expressed or written as:

y = mx + b, where the slope is m, and the y-intercept is b.

The slope of line q, with the equation y + 7 = 9(x + 4) is 9. The negative reciprocal of 9 is -1/9. This means line r that is perpendicular to line q and passes through (9, -10) has a slope, m = -1/9.

To write the equation of the line in slope-intercept form, first, substitute m = -1/9 and (a, b) = (9, -10) into y - b = m(x - a):
