The Central Limit Theorem justifies the use of the normal distribution for the sampling distribution of proportion.

The Central Limit Theorem states that under certain conditions, the sampling distribution of the mean of a random sample drawn from any population will be approximately normal, regardless of the shape of the population distribution. One of these conditions is that the sample size should be large enough, typically n >= 30.  For the sampling distribution of proportion, the Central Limit Theorem applies because the proportion is essentially a mean of a sample of binary data of a normal distribution  (e.g. success or failure). If the sample size is large enough, the sampling distribution of the proportion will be approximately normal, regardless of the shape of the population distribution.  The condition np >= 5 and nq >= 5 is used to ensure that the sample size is large enough for the normal approximation to be valid. In essence, this condition ensures that there are enough successes and failures in the sample to satisfy the conditions of the Central Limit Theorem. If this condition is not met, then the normal approximation may not be valid and alternative methods, such as the binomial distribution, should be used instead.

Answer:

C: ratio of the horizontal change to the vertical change of a line

Step-by-step explanation:

A and B are correct.

C is incorrect.

The velocity vector is v(t) = (3t^2, et, 1 - e-t), and the position vector is r(t) = (t^3, et + 4, t + e-t + 2).

The velocity vector v(t) can be found by integrating the acceleration vector a(t) with respect to time t, starting from the initial velocity v(0). The position vector r(t) can then be obtained by integrating the velocity vector v(t) with respect to time t, starting from the initial position r(0).

Integrating the acceleration vector a(t) = (6t, et, e-t) with respect to time t, we get the velocity vector v(t) = (3t^2, et, -e-t) + C, where C is the constant of integration.

Using the initial velocity v(0) = (0,0,1), we can substitute t = 0 into the expression for v(t) to find the value of the constant C. This gives us C = v(0) = (0,0,1).

Therefore, the velocity vector v(t) is v(t) = (3t^2, et, -e-t) + (0,0,1) = (3t^2, et, 1 - e-t).

Integrating the velocity vector v(t) = (3t^2, et, 1 - e-t) with respect to time t, we obtain the position vector r(t) = (t^3, et, t + e-t) + D, where D is the constant of integration.

Using the initial position r(0) = (0,4,2), we can substitute t = 0 into the expression for r(t) to find the value of the constant D. This gives us D = r(0) = (0,4,2).

Therefore, the position vector r(t) is r(t) = (t^3, et, t + e-t) + (0,4,2) = (t^3, et + 4, t + e-t + 2).

In summary, the velocity vector is v(t) = (3t^2, et, 1 - e-t), and the position vector is r(t) = (t^3, et + 4, t + e-t + 2).

The area of the tile can be found by dividing it into two triangles and one trapezoid. The area of the trapezoid is (5+3)/2 x 6 = 24 cm^2. The area of the two triangles can be found using the height of 5 cm and the base of 6 cm and 2 cm, respectively. The total area is then 24 + (5 x 6)/2 + (5 x 2)/2 = 24 + 15 + 5 = 44 cm^2. Therefore, the closest answer choice is 42.5 cm^2. The answer is (C) 42.5 cm^2.

Step-by-step explanation:

gg

Answer:

A = 3 cm^2

Step-by-step explanation:

To find the area of a triangle, we use the formula

A = 1/2 bh where b is the base and h is the height

A = 1/2 ( 3) (2)

A = 3 cm^2

y increases to 100 after approximately 6.7335 time units and drops to 1 after approximately 1.7273 time units. Rounded to four decimal places, the answers are:

t = 6.7335 (for y = 100)

t = 1.7273 (for y = 1)

This is a first-order differential equation with a constant coefficient, which can be solved using separation of variables:

dy/dt = k*y

dy/y = k*dt

Integrating both sides, we get:

ln(y) = k*t + C

where C is the constant of integration. Solving for y, we get:

y = e^(kt+C) = Ce^(kt)

where C = e^C is another constant of integration. Using the initial condition y(0) = y0 = 6, we get:

y = y0e^(kt)

To find the value of k, we use the fact that y increases to 100 or drops to 1:

For y = 100:

100 = 6e^(kt)

e^(k*t) = 100/6 = 50/3

k*t = ln(50/3)

t = ln(50/3)/k

For y = 1:

1 = 6e^(kt)

e^(k*t) = 1/6

k*t = ln(1/6) = -ln(6)

t = -ln(6)/k

To find the value of k, we can use either equation:

k = ln(50/3)/t = -ln(6)/t

Substituting the values, we get:

k = ln(50/3)/ln(50/3)*(-ln(6)) = -0.3293

Therefore, the equation for y is:

y = 6e^(-0.3293t)

To find the time at which y increases to 100 or drops to 1, we solve for t:

For y = 100:

100 = 6e^(-0.3293t)

t = ln(100/6)/(-0.3293) = 6.7335

For y = 1:

1 = 6e^(-0.3293t)

t = ln(1/6)/(-0.3293) = 1.7273

Step-by-step explanation:

A canoe rental shop is being built near a river. An equation of the line representing the river is y=1/4x+8. Each unit in the coordinate plane corresponds to 100 feet. Approximately how far is the canoe rental shop from the river? Round your answer to the nearest whole foot. The rental shop is at (-3,3).

Solution:

The distance between a point and a line is the perpendicular distance. The perpendicular distance is the shortest distance between the point and the line.

Given a point (\(x_1,y_1\)) and a line with the equation Ax + By + C = 0, the perpendicular distance (d) is given as:

\(d=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }\)

Given the equation of the line y = 1/4 x + 8

y - 1/4 x - 8 = 0

Therefore A = -1/4, B = 1 and C = -8

The point is (-3,3), therefore \(x_1=-3,y_1=3\)

\(d=\frac{|-1/4(-3)+(1*3)+(-8)|}{\sqrt{(-1/4)^2+1^2} }\\\\d=4.123\ unit\\\\but\ 1\ unit=100\ feet\\\\ d=4.123\ unit*1\ feet=412.3\ feet\)

h(x) = -7/6x - 25/6.

Given h(-1)=-2 and h(-7)=-9

For linear function h(x), we can use slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.

To find m, we can use the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

h(-1) = -2 is a point on the line, so we can write it as (-1, -2).

h(-7) = -9 is another point on the line, so we can write it as (-7, -9).

Now we can find m using these points: m = (-9 - (-2)) / (-7 - (-1)) = (-9 + 2) / (-7 + 1) = -7/6

Now we can find b using one of the points and m. Let's use (-1, -2):

y = mx + b-2 = (-7/6)(-1) + b-2 = 7/6 + b

b = -25/6

Therefore, the linear function h(x) is:h(x) = -7/6x - 25/6

We can check our answer by plugging in the two given points:

h(-1) = (-7/6)(-1) - 25/6 = -2h(-7) = (-7/6)(-7) - 25/6 = -9

The answer is h(x) = -7/6x - 25/6.

The sample mean is the best estimate of the population mean.

Option (C) is correct.

What is a sample mean?

The sample mean is a statistic obtained by calculating the arithmetic average of the values of a variable in a sample. If the sample is drawn from probability distributions having a common expected value, then the sample mean is an estimator of that expected value.

The concept used in this situation is an estimation.

The estimation in statistics is nothing but a data analysis framework that uses a combination of confidence intervals, effect sizes, and meta-analysis.

In this process we plan the experiments, analyze the data and interpret the results.

1. An estimate is a value that is based on some data and has been adjusted using statistical estimation.

2. An estimate of a population is expressed in two ways such as point estimation and interval estimation.

3. A point estimate of the population is defined as a single value of the statistic.

4. The interval estimate of the population is defined as the population parameter that lies between two numbers.

Step: 1

From the information, observe that the sample mean is not the best point estimate for the following measures.

1. Population standard deviation.

2. Population median

3. Sample standard deviation.

The sample mean is not a best-point estimate of the population standard deviation, population median, and sample standard deviation.

Since the sample means is not an unbiased estimate of these measures.

That is, the expectation of the sample mean value is not equal to the population standard deviation, population median, and sample standard deviation values.

From the information, observe that the sample mean is given and the sample mean is the best point estimate to the population mean.

The sample mean is the best point estimate of the population mean.

Since the sample mean is an unbiased estimator for the population.

Hence, the sample mean is the best estimate of the population mean.

Explanation:

Let's label the two brands of chocolate as A and B

Furthermore, define these variables

The amounts are in grams.

The two amounts must add to 900 grams, so x+y = 900. This can be solved to y = 900-x which we'll use later.

Since we have x grams of brand A, and brand A has 99% cocoa, this means 0.99x represents the amount of pure cocoa from brand A.

Similarly, brand B contributes another 0.70y grams of pure cocoa

Overall, we're dealing with 0.99x+0.70y grams of pure cocoa from the two brands mixed together.

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

Rolf needs 900 grams of final product. He wants it to be 80% cocoa, which means 80% of the 900 is going to be pure cocoa

80% of 900 = 0.80*900 = 720

Rolf wants 720 grams of pure cocoa after mixing the two brands together.

So this leads to the second equation: 0.99x+0.70y = 720

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

Let's apply substitution to replace y with 900-x

0.99x+0.70y = 720

0.99x+0.70( y ) = 720

0.99x + 0.70( 900-x ) = 720

At this point, we have a single variable in which we can isolate x fully.

0.99x + 0.70( 900-x ) = 720

0.99x + 0.70( 900) + 0.70(-x) = 720

0.99x + 630 - 0.70x = 720

0.29x = 720-630

0.29x = 90

x = 90/(0.29)

x = 310.344827586 which is approximate

Rounding to the nearest full gram, we get x = 310

Use this x value to find y

y = 900-x

y = 900-310.344827586

y = 589.655172414 which is also approximate

y = 590 when rounding to the nearest whole number

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

In summary, we have

Meaning that Rolf will need 310 grams of brand A to mix with 590 grams of brand B.

If we plugged those values into x+y = 900, then that equation works out.

If we tried the second equation, then,

0.99x+0.70y = 720

0.99*310+0.70*590 = 720

719.9 = 720

The slight discrepancy is due to the fact we rounded those approximate x and y values to the nearest whole number. We would get better accuracy if we rounded to say the nearest tenth or hundredth.
