Answer:

Step-by-step explanation:

Step-by-step explanation:

a

2/3 of 14 kg.

that means multiplying 2/3 × 14 = 28/3.

now we only need to do the division with remainder.

how often does 3 fit into 28 ? 9 times (9×3 = 27).

and then there is 1 left. and that means 1/3, since we are dividing by 3.

so, 2/3 of 14 kg = 9 1/3 kg

b

3/5 × 18

simply multiplication

54/5

and again division with remainder.

how often does 5 fit into 54 ? 10 times (10×5 = 50).

and there are 4 left. for a divisible by 5 that means 4/5.

so, 3/5 × 18 = 10 4/5

c

7/8 × 22

simply multiplication

154/8

again division with remainder.

how often does 8 fit into 154 ? 19 times (19×8 = 152).

and there are 2 left. so, 2/8 or 1/4.

so, 7/8 × 22 = 19 1/4

d

14 + 4/5

how many 1/5 are in 1 ? 5 !!! that defines the size of 1/5, because it is 1/5 of the whole, and the whole is 5/5 or 5×1/5.

so, if 1 has 5 times 1/5, how many 1/5 are in 14 ? well, 14×5 = 70

so, 14 = 70/5

and therefore,

14 + 4/5 = 70/5 + 4/5 = 74/5 = 14 4/5

surprise, surprise !

when we write something like 14 4/5, it has exactly the meaning 14 + 4/5.

but if the symbol was "÷" instead of "+" (it is really not to see in that picture) :

14 ÷ 4/5

remember, a division by a fraction is the same as the multiplication with the upside-down fraction :

14 × 5/4 = 70/4

how often does 4 fit into 70 ? 17 times (17×4 = 68).

and there are 2 left. that means 2/4 or 1/2.

14 ÷ 4/5 = 17 1/2

e

as for d.

if the operation is "+" then the result is for the same reasons 24 12/19.

if the operation is "÷" then we have

24 ÷ 12/19 = 24 × 19/12 = 2 × 19 = 38

Answer:

360!!!!!!!!!!!!!!!!!!!! ;)

Step-by-step explanation:

a) The relationship between b and c is that c cannot be zero.

b) b can be any nonzero constant and c is equal to 2.5 in this case.

In two dimensions, the compatibility equations for strain are,0

∂εx/∂y + ∂γxy/∂x = 0

∂εy/∂x + ∂γxy/∂y = 0

where εx and εy are the normal strains in the x and y directions, respectively, and γxy is the shear strain.

Using the given strain field, we can calculate the strains,

εx = -4.5cx² + 10.5cy

εy = 1.5cx² - 7.5cy²

γxy = 1.5bxy

Taking partial derivatives and plugging them into the compatibility equations, we get,

⇒ -9cx + 0 = 0

⇒ 0 + (-15cy) = 0

These equations must be satisfied for the strain field to be compatible. From the first equation,

We get cx = 0, which means c cannot be zero.

From the second equation, we get cy = 0,

Which means b can be any nonzero constant.

For part b:

We are asked to find the displacements u and v corresponding to the given strain field at points (3, 7), assuming they are zero at point (0, 0) and using c = 2.5.

To find the displacement components,

We need to integrate the strains with respect to x and y. We get,

u = ∫∫εx dx dy = ∫(10.5cy) dy = 5.25cy²

v = ∫∫εy dx dy = ∫(1.5cx² ) dx - ∫(7.5cy²) dy = 0.5cx³ - 2.5cy³

Plugging in the values of c and b, we get,

u = 5.25(2.5)(7)²  = 767.62

v = 0.5(2.5)(3)³ - 2.5(7)³ = -8583.75

Therefore,

The displacements at points (3, 7) are u = 767.62 and v = -8583.75.

Step-by-step explanation:

9m + 3m - m = ?

just look at it without the variables: m

9 + 3 - 1 = ?

The reason there is a 1 before the m is because there is always atleast a 1 before a variable. 1 x m = m, but 0 x m = 0. so '1'.

ok so now lets solve

9 + 3 - 1

 12 - 1

    11

Triangle 1 is rotated to result in triangle 2;

Triangle 1 is dilated to result in triangle 3;

Triangle 1 is reflected to result in triangle 4;

Triangle 1 is stretched to result in triangle 5.

Triangles are 2D shapes that can undergo several transformations to change their orientation or size.

In the given question, Triangle 1 has undergone four different transformations to obtain triangles 2, 3, 4, and 5.

Below are the explanations for each of the transformations:

Rotation:

Triangle 1 has been rotated to result in triangle 2.

Rotation is a transformation in which a shape is turned around a point.

In this case, Triangle 1 has been rotated 90 degrees clockwise around a point to get triangle 2.

Dilation:

Triangle 1 has been dilated to result in triangle 3.

Dilation is a transformation in which a shape is enlarged or shrunk uniformly.

In this case, Triangle 1 has been enlarged uniformly to get triangle 3.

Reflection:

Triangle 1 has been reflected to result in triangle 4.

Reflection is a transformation in which a shape is flipped over a line.

In this case, Triangle 1 has been reflected across the y-axis to get triangle 4.

Stretching:

Triangle 1 has been stretched to result in triangle 5.

Stretching is a transformation in which a shape is expanded or contracted non-uniformly.

In this case, Triangle 1 has been expanded in the y-direction and contracted in the x-direction to get triangle 5.

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.

The investment will double in nine years at an interest rate of approximately 8.09% compounded annually.

To find the value of the (P/A,8%,145) factor, we can use the general formula for the present worth of an annuity:

(P/A, i%, n) = (1 - (1 + i)^(-n)) / i

Substituting the values given:

i = 8%

n = 145

(P/A,8%,145) = (1 - (1 + 0.08)^(-145)) / 0.08

Using a financial calculator or spreadsheet software, we can calculate the value of (P/A,8%,145) as follows:

(P/A,8%,145) ≈ 43.7276 (rounded to four decimal places)

Therefore, the correct choice for the value of (P/A,8%,145) is:

C. (P/A,8%,145) = (P/A,8%,100)(P/A,8%,45) ≈ 43.7276 (rounded to four decimal places)

Regarding the second question, to find the interest rate at which an investment will double in nine years, we can use the future worth factor formula:

(F/P, i%, n) = (1 + i)^n

We want the investment to double, so we have:

(1 + i)^9 = 2

Taking the ninth root of both sides:

1 + i = 2^(1/9)

Solving for i:

i ≈ 0.0809 or 8.09% (rounded to two decimal places)

Therefore, the investment will double in nine years at an interest rate of approximately 8.09% compounded annually.

Step-by-step explanation:

The manager wants to control the maximum probability of Type I error at 1% (i.e. the manager wants the significance level to be 1%). To calculate the critical value, we need to find the Z-score associated with a 1% significance level.
To find the critical value, we can use a Z-table or a Z-score calculator. Since the significance level is 1% (0.01), we need to find the Z-score corresponding to the area of 0.99 (1 - 0.01) in the upper tail of the standard normal distribution.
By looking up the Z-table or using a Z-score calculator, we find that the Z-score corresponding to a 0.99 cumulative probability is approximately 2.33. The critical value the manager should use to conduct the hypothesis test is 2.33.

To calculate the probability of Type II error, we need to specify an alternative hypothesis and determine the corresponding population mean value. In this case, the alternative hypothesis is that the mean daily output is greater than 200, and the specified population mean value is 205.

To calculate the probability of Type II error, we need to find the area under the null hypothesis distribution that falls to the right of the critical value. In other words, we need to find the probability that the test statistic, assuming the null hypothesis is true, falls in the rejection region. Since we are assuming the population mean is 205, we can calculate the Z-score using the formula:

Z = (sample mean - population mean) / (standard deviation / sqrt(sample size))
Substituting the values, we get:
Z = (205 - 200) / (18 / sqrt(81)) = 5 / (18 / 9) = 5 / 2 = 2.5

Now, we can calculate the probability of Type II error by finding the area under the null hypothesis distribution to the right of the critical value, which is 2.33. Using the Z-table or a Z-score calculator, we find that the probability of Type II error is approximately 0.0062, or 0.62%.
If the sample mean turns out to be 205, we compare it to the critical value. If the sample mean is greater than the critical value (2.33), we reject the null hypothesis. In this case, since the sample mean is 205, which is greater than the critical value of 2.33, we would reject the null hypothesis. The conclusion of the test would be that there is sufficient evidence to suggest that the mean daily output is greater than 200.

Approximately 304,657,600 Americans were there in July 2009 based on the estimated 2008 growth rate of 0.88%.

To find the approximate US population in July 2009, we need to apply the growth rate of 0.88% to the initial population in July 2008.

Convert the growth rate from percentage to decimal:

0.88% = 0.0088
Calculate the number of people added to the population in 2008: 302,000,000 * 0.0088 = 2,657,600

The probability of event E2 occurring, given that event E1 has happened is called a conditional probability. This type of probability is denoted by P(E2 | E1), which reads as "the probability of E2 given E1."

Conditional probability helps to calculate the probability of an event that depends on the occurrence of another event. For example, consider the following scenario: A company has two factories, and each factory produces a different type of product. The probability of a defective product from factory 1 is 0.05, and the probability of a defective product from factory 2 is 0.03.

Suppose a customer buys a product, and it is known that the product came from factory 1. What is the probability that the product is defective? To solve this problem, we use conditional probability. Let E1 be the event that the product came from factory 1, and E2 be the event that the product is defective.

Then, we want to find P(E2 | E1), which is the probability of the product being defective given that it came from factory 1. Using the formula for conditional probability, we get:
P(E2 | E1) = P(E1 and E2) / P(E1)
= (0.05 x 1) / 0.5
= 0.1
Therefore, the probability of the product being defective given that it came from factory 1 is 0.1 or 10%.
