Mary's scarf is 64 centimeters long. How many millimeters is the length of the scarf?

Answer:

0.28

Step-by-step explanation:

High-quality soil gives seed: 0.8 chance of survival

Medium-quality soil gives seed : 0.3 chance of survival

Low-quality soil gives seed: 0.1 chance of survival

Proportions/frequency of soils:

High-quality soil = 30% = 0.3

Medium-quality soil = 20% = 0.2

Low-quality soil = 50% = 0.5

probability of a seed landing on a particular soil type ∝ frequency of that type in the  habitat

probability that a seed dies before landing = 0.2

A) The overall probability of seed survival

first we have to determine the probability of seed survival if it lands

= ∑ (frequency of soil * chance of seed survival)

= (0.8 * 0.3) + ( 0.3 * 0.2 ) + ( 0.1 * 0.5 ) = 0.35

hence overall probability of seed survival

= ( 1 - 0.2 ) * 0.35 = 0.28

There are 2 angles measurements do you need to figure out the measurements of all the labeled angles in the figure.

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

There are 4 angles is shown in figure.

Now, If we know the value of angle 1 then by vertically opposite angle the value of angle 3 is same as angle 1.

And, If we know the value of angle 2 then by vertically opposite angle the value of angle 4 is same as angle 2.

Thus, There are 2 angles measurements do you need to figure out the measurements of all the labeled angles in the figure.

After analyzing, it can be concluded that the functions f and g are:

A. f(0) is larger than g(0).

B. f(3) is larger than g(3).

To determine which of the two functions is larger at any given point, one must compare the heights of the two functions at the same point on the x-axis. At point x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0).

Similarly, at point x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3).

To compare which of two functions is larger at any given point, we need to compare the heights of the two functions at the same point on the x-axis. For example, at x=0, the height of the f(x) function is larger than the height of the g(x) function, so f(0) is larger than g(0). The same comparison can be made at any other point on the x-axis.

For example, at x=3, the height of the f(x) function is larger than the height of the g(x) function, so f(3) is larger than g(3). This comparison can be done for any point on the x-axis, which will allow us to determine which of the two functions is larger at any given point.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

Answer:

p = 1.25x + 70

Step-by-step explanation:

We know she makes $70 each day and we know she makes $1.25 for each computer she sells.

With that we can add it into an equation because we can add 70 + 1.25, but the amount for each computer she sells in unknown so we give it an x which makes it 1.25x.

So, we do 1.25x + 70, but the amount total is missing so that is our p.

This finally completes our equation, p = 1.25x + 70 or  1.25x + 70 = p

Answer:

1/52

Step-by-step explanation:

theres 52 cards and there is only one three of squares so there is a 1/52 chance

Answer:

3/52

Step-by-step explanation:

Area of R= 6√3 square units, volume of the solid generated when R is revolved about the horizontal line y = 3 is 9π cubic units and volume of the solid generated when R is revolved about the vertical line x = 10 is 17.91 cubic units.

What is volume?

In mathematics, volume refers to the measure of the amount of space occupied by a three-dimensional object.

a) To find the area of R, we need to integrate the function y = \(\sqrt{(x-1)\) from x = 1 to x = 10 (the region bounded by the x-axis and the vertical line x = 10). So we have:

Area of R = ∫[1,10] \(\sqrt{(x-1)\) dx

Using the substitution u = x - 1, we can rewrite the integral as:

Area of R = ∫[0,9] \(\sqrt{(u)\) du

Using the power rule for integration, we have:

Area of R = (2/3)\(u^{(3/2)\) |[0,9]

= (2/3)\((9^{(3/2)} - 0)\)

= 18√3/3

= 6√3

Therefore, the area of R is 6√3 square units.

b) To find the volume of the solid generated when R is revolved about the horizontal line y = 3, we can use the method of disks. We need to integrate the area of the circle generated by each vertical slice of R as it rotates around the line y = 3. The radius of each circle is given by r = y - 3, and the area of each circle is given by A = π\(r^2\). So we have:

Volume = ∫[1,10] π\((y-3)^2\) dx

Using the substitution u = y - 3, we can rewrite the integral as:

Volume = π ∫[0,√9] \(u^2\) du (substituting the limits by the boundary conditions)

Using the power rule for integration, we have:

Volume = π(\(u^3\)/3) |[0,3]

= π(\(3^3\)/3 - 0)

= 9π

Therefore, the volume of the solid generated when R is revolved about the horizontal line y = 3 is 9π cubic units.

c) To find the volume of the solid generated when R is revolved about the vertical line x = 10, we can use the method of cylindrical shells. We need to integrate the volume of each cylindrical shell generated by each vertical slice of R as it rotates around the line x = 10. The radius of each cylindrical shell is given by r = 10 - x, and the height of each cylindrical shell is given by h = y. So we have:

Volume = ∫[1,10] 2πrh dx

= ∫[1,10] 2πy(10-x) dx

= 2π ∫[1,10] y(10-x) dx

Using the substitution u = 10 - x, we can rewrite the integral as:

Volume = 2π ∫[0,9] (10-u) sqrt(u-1) du (substituting the limits by the boundary conditions)

Using integration by parts with u = (10 - u) and dv = sqrt(u-1) du, we have:

Volume = 2π [-2/3 (10-u) \((u-1)^{(3/2)\) - 4/5 \((u-1)^{(5/2)\)] |[0,9]

= 2π [(2/3)(9)(2√2) + (4/5)(8√2) - (2/3)(-1)\((1)^{(3/2)\) - (4/5)(0)]

= 2π (12√2/5 + 72√2/5 + 2/3)

= 48π√2/5

Therefore, the volume is approximately 17.91 cubic units.

Using linear approximation, the expression √125.2 can be approximated as approximately 10.02.

To find the equation of the tangent line to the function f(x) = √x at x = 125, determine the slope (m) and the y-intercept (b) of the tangent line.

First, find the slope (m) using the derivative of the function f(x) = √x:

f'(x) = 1 / (2√x)

Evaluate the derivative at x = 125:

f'(125) = 1 / (2√125) = 1 / (2 × 5) = 1/10

Now, find the y-coordinate of the point on the function f(x) at x = 125:

f(125) = √125 = 5

So, the tangent line at x = 125 passes through the point (125, 5) and has a slope of 1/10.

Using the point-slope form of a linear equation, the equation of the tangent line can be written as:

y - 5 = (1/10)(x - 125)

To simplify, multiply through by 10:

10y - 50 = x - 125

Rearranging the equation, express it in the form y = mx + b:

y = (1/10)x - 75/10 + 5

Simplifying further:

y = (1/10)x - 75/10 + 50/10

Combining the terms:

y = (1/10)x - 25/10

Therefore, the equation of the tangent line to f(x) = √x at x = 125 is y = (1/10)x - 25/10.

Now, use this tangent line to approximate the value of √125.2:

Substitute x = 125.2 into the equation:

y = (1/10)(125.2) - 25/10

y = 12.52 - 2.5

y ≈ 10.02

So, using linear approximation, approximate √125.2 as approximately 10.02.

The length of side CB to one decimal place is 89.3.

To find the length of side CB in the given triangle, we can use the sine rule. The sine rule states that in a triangle, the ratio of the length of a side to the sine of its opposite angle is constant.

In this case, we have the angle C as 53° and the side opposite to it, side CB, as the unknown. Let's denote the length of side CB as x.

According to the sine rule:

sin(C) / x = sin(A) / AB

We know that angle A is 37° and AB is 120 units. Plugging in the values:

sin(53°) / x = sin(37°) / 120

To find x, we can rearrange the equation:

x = (120 * sin(53°)) / sin(37°)

Calculating this expression gives us:

x ≈ 89.32

Rounding this value to one decimal place, the length of side CB is approximately 89.3.

el hombre tenía 50 acciones.

La pregunta es, ¿cuántas acciones poseía el hombre si declararon un dividendo del 6% pagadero en acciones y tenía 50 acciones con un valor de $30 cada una?Para calcular cuántas acciones tenía el hombre,

se puede utilizar la siguiente fórmula:Dividendos = Número de acciones * Precio por acción * Tasa de dividendosDe esta fórmula,

podemos despejar el número de acciones. Así, tenemos:Número de acciones = Dividendos / (Precio por acción * Tasa de dividendos)De los datos del problema, se sabe que el hombre tenía 50 acciones con un valor de $30 cada una.

Además, la corporación declaró un dividendo del 6% pagadero en acciones. Por lo tanto, la tasa de dividendos es del 6%.Para resolver el problema, primero debemos calcular el valor del dividendo que se pagará en acciones.

Para ello, se debe multiplicar el valor de las acciones del hombre por la tasa de dividendos.

Así, tenemos:Valor del dividendo = 50 acciones * $30 * 0.06 = $90El valor del dividendo es de $90. Ahora, podemos sustituir este valor en la fórmula para calcular el número de acciones que tenía el hombre.

Así, tenemos:Número de acciones = $90 / ($30 * 0.06) = 50 accionesPor lo tanto,
