Twenty four blood samples were selected by taking every seventh blood sample from racks holding 199 blood samples from the morning draw at a medical center ANSWER BOTH A AND B

Answers

a. FPCF for this sample is FPCF = √(199/24) = 2.89.

b. The population cannot be considered effectively infinite, so the answer is no.

What is FPCF?

When the sample size is significant compared to the size of the community, the Finite Population Correction Factor, also known as the FPC factor, is applied. The population in most cases is so vast that typical sample sizes are insufficient to raise concerns about the need for the FPC.

The recommendation is to use the FPC when the sample size to population size ratio is higher than 5%. The FPCF must be used, for instance, if the population number is 300 and the sample size is 30, which results in a ratio of 10%.

a. To calculate the FPCF (finite population correction factor) for this sample, we can use the formula:

FPCF = √(N/n)

where N is the population size, and n is the sample size.

In this case, N = 199 (the number of blood samples in the racks), and n = 24 (the number of samples selected every seventh blood sample).

FPCF = √(199/24) = 2.89 (rounded to two decimal places)

b. To determine whether the population should be considered effectively infinite, we need to compare the sample size to the population size. A general rule of thumb is that the population can be considered effectively infinite if the sample size is less than 5-10% of the population size.

In this case, the sample size is 24, which is approximately 12% of the population size of 199. Therefore, the population cannot be considered effectively infinite, and the FPCF should be applied to adjust for the finite population size.

Solve a triangle with b =7, c =10, and A= 51. round to the nearest tenth

Answers

The sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

What is a triangle?

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles.

To solve the triangle, we need to find the values of the remaining sides and angles. We can start by using the Law of Sines, which states that:

a / sin A = b / sin B = c / sin C

where a, b, and c are the sides of the triangle, and A, B, and C are the angles opposite to those sides.

Using the given values, we can write:

a / sin 51 = 7 / sin B

a / sin 51 = 10 / sin C

To solve for a, we can use either of the two equations above. Let's use the first one and solve for sin B:

sin B = (7 / sin 51) * sin B

sin B = 7 / (sin 51 / sin B)

sin B = 7 / sin(180 - 51 - B)

sin B = 7 / sin(129 - B)

Using the sine rule, we can determine the angle B:

sin B / 7 = sin(129 - B) / 10

sin B = (7/10) * sin(129 - B)

sin B = (7/10) * (sin 129 * cos B - cos 129 * sin B)

sin B = (7/10) * sin 129 * cos B - (7/10) * cos 129 * sin B

(7/10 + (7/10) * cos 129) * sin B = (7/10) * sin 129 * cos B

sin B = (7/10) * sin 129 * cos B / (7/10 + (7/10) * cos 129)

sin B = sin 51.5

B = sin(sin B)

B = sin(sin 51.5)

B ≈ 51.5°

We can now find the remaining angle, C:

C = 180 - A - B

C = 180 - 51 - 51.5

C ≈ 77.5°

Finally, we can use the Law of Sines again to find the remaining side, a:

a / sin A = c / sin C

a / sin 51 = 10 / sin 77.5

a = (10 * sin 51) / sin 77.5

a ≈ 8.3

Therefore, the sides of the triangle are a ≈ 8.3, b = 7, and c = 10, and the angles are A = 51°, B ≈ 51.5°, and C ≈ 77.5°.

can you always divide by e^x? and what example can you give to prove this statement

Answers

Answer: No, you cannot always divide by e^x. When e^x equals zero, dividing by it would result in an undefined value or division by zero error.

For example, consider the function f(x) = e^x. We know that e^x is never equal to zero for any value of x. Therefore, we can always divide by e^x for any value of x, and the resulting quotient will be well-defined.

However, if we consider the function g(x) = 1 / e^x, we cannot always divide by e^x. When e^x equals zero, g(x) will be undefined. In fact, there is no value of x for which e^x is equal to zero, so the function g(x) is well-defined for all values of x.

In summary, dividing by e^x is allowed for most cases, except when e^x equals zero.

Answers

For the given cone, the approximate volume of the toy top is 106.81 cubic centimeters. The three dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex.

What is volume?

Volume is a three-dimensional quantity that measures the amount of space occupied by an object or a region in space.

The volume of the toy top can be calculated by finding the volumes of the cone and cylinder and then adding them together.

The volume of the cone is given by the formula V = (1/3)π[tex]r^{2}[/tex]h, where r is the radius and h is the height of the cone. In this case, the slant height is given, so we need to use the Pythagorean theorem to find the height:

h = [tex]\sqrt{(l^2 - r^2)[/tex] = [tex]\sqrt{(10^2 - 6^2)[/tex] = √(64) = 8 cm

Therefore, the volume of the cone is:

V_cone = (1/3)π[tex]r^2[/tex]h = (1/3)π([tex]6^2[/tex])(8) ≈ 100.53 [tex]cm^3[/tex]

The volume of the cylinder is given by the formula V = π[tex]r^2[/tex]h, where r is the radius and h is the height of the cylinder. In this case, the diameter is given, so we need to divide by 2 to get the radius:

V_cone = (1/3)πh = (1/3)πr = d/2 = 1 cm = 2 cm

Therefore, the volume of the cylinder is:

V_cylinder = π[tex]r^{2}[/tex]h = π([tex]1^{2}[/tex])(2) ≈ 6.28

The total volume of the toy top is:

V = V_cone + V_cylinder ≈ 100.53 + 6.28  ≈  106.81 T

Therefore, the approximate volume of the toy top is 106.81 cubic centimeters.

To find the price of the chair in the furniture store, we need to calculate the retail price, which is the wholesale price plus the markup. The markup is calculated by multiplying the wholesale price by the markup rate as a decimal:

markup = 0.22 x $181 = $39.82

So the retail price is:

$181 + $39.82 = $220.82

Rounding to the nearest cent, we get the final answer:

A particle moves along the x-axis with velocity given by v(t) = 6t² + 8t - 5
for time t≥ 0. If the particle is at position x = -2 at time t = 2, what is
the position of the particle at time t = 1?

Answers

The position of the particle at time t = 1 would be -1.

Position of a particle at a time, t

To find the position of the particle at time t = 1, we need to integrate the velocity function v(t) from t = 0 to t = 1, and add it to the initial position x = -2:

x(1) = -2 + ∫[0,1] v(t) dt

Integrating v(t), we get:

x(1) = -2 + ∫[0,1] (6t² + 8t - 5) dt

x(1) = -2 + [2t³ + 4t² - 5t] from 0 to 1

x(1) = -2 + [2(1)³ + 4(1)² - 5(1)] - [2(0)³ + 4(0)² - 5(0)]

x(1) = -2 + [2 + 4 - 5]

x(1) = -2 + 1

x(1) = -1

On the first
day there were 4 laborers getting time and a half and 20 who were not for a total of $2080. On the
second day there were 2 laborers getting time and a half and 15 who were not for a total of $1440.
How much were the time and a half workers getting per day compared to the laborers who did not get
time and a half.

Answers

Answer:

  "time and a half" workers were paid 50% more per day

Step-by-step explanation:

You want to know the relative daily pay rates of laborers making time and a half versus those who were not. 4 getting time and a half and 20 not earned a total of $2080, while 2 getting time and a half and 15 not earned a total of $1440.

Setup

We can let x and y represent the daily pay of time and a half workers, and those not earning time and a half. The two payrolls can be described by ...

  4x +20y = 2080

  2x +15y = 1440

Solution

Subtracting the first equation from 2 times the second, we have ...

  2(2x +15y) -(4x +20y)  = 2(1440) -(2080)

  10y = 800 . . . . . . . simplify

  y = 80 . . . . . . . . . . divide by 10

  2x +15(80) = 1440

  2x = 240 . . . . . . . . . . subtract 1200

  x = 120 . . . . . . . . divide by 2

Workers getting time and a half made $120 per day; workers not getting time and a half made $80 per day. Workers getting time and a half made half again as much as those who didn't: $40 per day more, or 50% more, or half-again as much.

__

Additional comment

"Time and a half" means the pay is 50% more. That's what we see here. You don't need any math to say those getting time and a half were getting 50% more per day.

calculate the area of the shaded region. the apothem is 2 ft, and the shaded area is 110 degrees. the figure is a circle.

Answers

The area of the shaded region is 1.916 ft²

What is Area?

Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.

To calculate the area of the shaded region, we need to find the area of the entire circle and subtract the area of the unshaded portion.

The central angle corresponding to the shaded region is 110 degrees. The entire circle has a central angle of 360 degrees.

The unshaded portion of the circle is the sector that corresponds to the central angle of 360 - 110 = 250 degrees. The area of a sector of a circle with radius r and central angle θ is given by the formula:

A = (θ/360)πr²

Substituting θ = 110 degrees and r = 2 ft, we get:

A = (110/360)π(2)

A =  (0.305)π(2)

A =  (0.305)π(2)

A = 0.61π

A = 1.916 ft²

Therefore, the area of the shaded region is 1.916 ft².

So, the value of the car after 13 years is approximately $13,330.

What is initial value?

In mathematics, an initial value refers to the value of a function or a variable at a specific starting point or initial condition. For example, when solving a differential equation, the initial value is the value of the function at the starting point or initial time.

In the context of calculus, the initial value of a function f(x) at a point x=a is denoted by f(a). In the context of differential equations, the initial value of a function y(x) at a point x=a is denoted by y(a) or y(a) = y0.

he given exponential function can be written as:

[tex]v(t) = 25,900(0.95)^t[/tex]

where t is the age of the car in years.

To find the initial value of the car, we need to evaluate v(0):

[tex]v(0) = 25,900(0.95)^0[/tex]

[tex]v(0) = 25,900(1)[/tex]

The solution to the triangle is: a ≈ 22.4, b = 4 , c ≈ 77.2 ,A = 27° ,B ≈ 42.5°

C ≈ 110.5°  we got the answer by using law of sine

what is  law of sine?

The Law of Sines, also known as the Sine Rule, is a mathematical formula used in trigonometry to relate the sides and angles of a non-right-angled triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.

In the given question,

Using the law of sines and the fact that the angles of a triangle sum up to 180 degrees, we can solve for the missing parts of the triangle:

sin(A)/a = sin(B)/b = sin(C)/c

sin(27)/a = sin(B)/42 = sin(C)/72

We can use the first equation to solve for a:

a = b(sin(A)/sin(B)) = 42(sin(27)/sin(B)) ≈ 22.4161

Next, we can use the second equation to solve for sin(B):

sin(B) = b(sin(A)/a) = 42(sin(27)/a) ≈ 0.6822

Taking the inverse sine, we find that B ≈ 42.4827 degrees.

Now we can use the fact that the angles of a triangle sum up to 180 degrees to solve for C:

C = 180 - A - B ≈ 110.5173 degrees.

Finally, we can use the law of sines again to solve for the remaining side, c:

c = a(sin(C)/sin(A)) = 22.4161(sin(110.5173)/sin(27)) ≈ 77.2352

Therefore, the solution to the triangle is:

a ≈ 22.4

b = 42

c ≈ 77.2

A = 27°

B ≈ 42.5°

C ≈ 110.5°

         First, we will graph these equations. See attached. One has a y-intercept of 3 and then moves right one unit for every up down (we get this from the slope of 1). The other has a y-intercept of 4, and then moves down two units for every unit right (we get this from the slope of 1).

         The point of intersection is the solution, this is the point at which both graphed lines cross each other. Our solution is:

                         (-3, 0)     x = -3, y = 0

Answer:

(-3, 0)

Step-by-step explanation:

When we graph the equations:

y = x + 3,

y = -2 - 6,

we can see that they intersect at (-3, 0).

Therefore, that is the solution to the system.

— Extra note —

When graphing a line from a slope-intercept form equation (y = mx + b), we know the following:

m is the line's slope (rise over run)

b is the y-coordinate of the line's y-intercept

Consider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6,209 patients treated with this drug, 160 developed the adverse reaction of nausea. Use 0.01 a significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction?

Answers

For given dataset,  the p-value is greater than the significance level of 0.01, we fail to reject the null hypothesis.

What exactly is a data set?

A dataset is a collection of data points or observations that are related to each other in some way. Each data point in a dataset represents a single instance or measurement of some variable or phenomenon that is being studied.

A dataset can take many different forms depending on the type of data being collected and the purpose of the study.

Now,

To test the claim that 3% of users develop nausea, we will use a hypothesis test with a significance level of 0.01.

Let p = true proportion of users who develop nausea.

Null Hypothesis: H0: p = 0.03

Alternative Hypothesis: H1: p > 0.03 (one-tailed test)

We will use the normal approximation to the binomial distribution since np and n(1-p) are both greater than 10, where n is the sample size and p is the hypothesized proportion.

The test statistic is calculated as follows:

z = (P - p)/√(p(1-p)/n)

Here P = sample proportion and n = sample size.

The sample proportion is:

P = 160 / 6209 = 0.0258

Substituting the values, we get:

z = (0.0258 - 0.03) / √(0.03 x 0.97 / 6209) = -1.72

Using a z-table or calculator, we find that the p-value for this test is approximately 0.043. Since the p-value is greater than the significance level of 0.01, we fail to reject the null hypothesis.

Therefore, we do not have sufficient evidence to support the claim that more than 3% of users develop nausea. However, we should still be cautious about this adverse reaction and continue monitoring it.

select all values for b that make the equation 8(x - 3) = 2x + b + 6x have no solutions for x. -24 -3 3 24​

Answers

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

Answer:  [tex]\textsf{B (-3), C (3), and D (24)}[/tex]

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

Given:  [tex]\textsf{8(x - 3) = 2x + b + 6x}[/tex]

Find: [tex]\textsf{Which values for b are not a solution}[/tex]

Solution: In order to make it easier for us to determine the answer, let us first simplify the expression that was given to us.  We can do that by first combining like terms on the right side of the equation and distributing the 8 on the left side of the equation.

[tex]\textsf{8(x - 3) = 2x + b + 6x}[/tex][tex]\textsf{(8 * x) + (8 * -3) = 8x + b}[/tex][tex]\textsf{8x - 24 = 8x + b}[/tex]

We can now subtract 8x from both sides of the equation.

[tex]\textsf{8x - 8x - 24 = 8x - 8x + b}[/tex][tex]\textsf{-24 = b}[/tex]

Now that we know that b is equal to -24, that means that any value other than -24 would cause the equation to have no solutions.  Therefore, the correct answer would be B (-3), C (3), and D (24).

To find the average result of rolling a six-sided dice, Josh rolls a dice 100 times.
The table shows how many times Josh rolled each number. What is the mean,
or average, of the dice rolls?

Answers

Answer:16.7

Step-by-step explanation: So the first step is to add all of the numbers in the second column. (15,18,14,16,19,18). At the end of your problem it says 100. So you have 6 different numbers, and 100. You will do 100 divided by 6. Finally you will get 16.66 and you will just round it.

Step-by-step explanation:

Graph with Numbers

The coordinate plane is a two-dimensional plane that is divided into four quadrants. The upper-right quadrant is known as quadrant one, and the following quadrants go in counter-clockwise order: quadrant two, quadrant three, quadrant four (see image below). Quadrants are typically labeled using Roman numerals (I, II, III, and IV). The coordinate plane is comprised of two axes that are perpendicular lines, meaning when they are joined together, they create four right angles. The x-axis is the horizontal axis, and the y-axis is the vertical axis. The point where the two axes are joined together is called the origin. The coordinates of the origin are (0, 0). This means that the x-coordinate is 0 and the y-coordinate is 0. Ordered pairs are always written in the format (x, y).

The coordinate plane

The coordinate plane has four quadrants, a horizontal x-axis and vertical y-axis, and the origin is the point in the center.

The left side of the x-axis contains negative numbers. Traveling to the left on the coordinate plane indicates the x-value is getting smaller. The right side of the x-axis contains positive numbers. Traveling to the right on the coordinate plane indicates the x-value is getting larger. The upper half of the y-axis contains positive numbers. Traveling upward on the coordinate plane indicates the y-value is getting larger. The lower half of the y-axis contains negative numbers. Traveling downward on the coordinate plane indicates the y-value is getting smaller.

In the following image, point A is graphed on the coordinate plane. The coordinates for point A are (3, 2). This means that the x-value is 3 and the y-value is 2. To graph point A on the coordinate plane, start at the origin and go three spaces to the right (because the x-value, 3, is positive) and two spaces upward (because the y-value, 2, is positive). Since the x-value and y-value are both positive, point A will be in quadrant I.

Graphing the point (3, 2)

In order to graph the point (3, 2), move left three spaces and up two spaces on the coordinate plane.

The drink of the people at large in Japan is green tea. The preparation of good tea is regarded by the Japanese as the height ofsocial art. For that reason, it is an important element in the domestic, political, and general life of the country.Tea is the beverage--the masterpiece-of every meal, even if it be nothing but boiled rice. Every artisan and laborer, going to work,carries a rice-box of lacquered wood, a kettle, a tea-caddy, a tea-pot, a cup, and chop-sticks. Milk and sugar are generally avoided. TheJapanese and the Chinese never indulge in either of these ingredients in tea. The use of these, they claim, spoils the delicate aroma.From the highest court circles down to the lowliest and poorest of the Emperor's subjects, it is the custom in both Japan and China tooffer tea to every visitor upon his or her arrival. Not to do this would be an unpardonable breach of national manners.

As soon as a guest is seated upon amat, a small tray is set before the master of the house. Upon this tray is a tiny tea-pot with a handle at right angles to the spout. Otherparts of this outfit include a highly artistic tea-kettle filled with hot water, and a number of small cups, set in metal or bamboo trays. Thesetrays are used for handing the cups around, but the guest is not expected to take one. The cups being without handles, are not easy tohold. The visitor must therefore be careful lest he or she let one slip through untutored fingers.The tea-pot is drenched with hot water before the tea is put in. Then, more hot water is poured over the leaves, and soon poured offinto the cups. This is repeated several times.
