Step-by-step explanation:

B' represents the complement of set B, which includes all elements in U that are not in B. Therefore, B' = {0, 1, 2, 5, 6, 7}.

A - B' means all elements in set A that are not in set B'. In other words, we need to remove all the elements in set B' from set A.

A - B' = {3, 6}

Therefore, the elements in A - B' are 3 and 6.

Answer:

14 5/8

Step-by-step explanation

1) Convert the mixed number to an improper fraction

3 3/8 = 3 x 8 + 3 / 8 = 24 + 3/ 8=  27/8

2) Convert the second mixed number to an improper fraction

4 1/3 = 4 x 3 + 1/ 3 = 12 + 1/3= 13/3

3) Multiply 27/8 x 13/3= 351/24 divided by 3 = 117/8 117/8 as a mixed number is 14 5/8

4) 14 5/8 is the final answer simplified

Answer:

\(\frac{117}{8}\) (or \(14\frac{5}{8}\) in mixed number form)

Step-by-step explanation:

1) First, convert \(3\frac{3}{8}\) and \(4\frac{1}{3}\) into improper fractions. (Multiply the denominator by the whole number at the front, then add the numerator. The number that you receive from this would be the new numerator, and the denominator would still be the same.) This would be \(\frac{27}{8}\) and \(\frac{13}{3}\) respectively.

2) Multiply the two improper fractions. Multiply the numbers of the numerators and denominators together:

\(\frac{27}{8}\)·\(\frac{13}{3}\)

\(\frac{351}{24}\)

3) Simplify the fraction. Find a number that both 351 and 24 can divide evenly into - in this case, it is 3. Divide both 351 and 24 by 3 and receive the final answer:

\(\frac{351}{24}\)÷\(\frac{3}{3}\)

\(\frac{117}{8}\)

If you need it in mixed number form, find what times 8 can get closest to the number 117 without going over it. In this case, it is 14, since 14 times 8 is 112, and 112 is the biggest number closest to 117 that is still under it. 14 would be the whole number at the front Include the remainder, or how far away 112 is from 117, which is 5, at the numerator. The denominator would stay the same. Therefore, the answer in mixed number form is \(14\frac{5}{8}\).

In this experiment, we conducted 10 trials with each trial consisting of flipping a coin 4 times. The sample proportion, denoted as p^, represents the proportion of heads. We will now calculate the sample proportion for each trial.

To calculate the sample proportion, we need to determine the number of heads observed in each trial and divide it by the total number of coin flips (4 in this case). Let's denote the number of heads as X in each trial. The sample proportion p^ is then given by p^ = X/4.

For example, let's say in the first trial we observed 3 heads. The sample proportion for this trial would be p^ = 3/4 = 0.75. Similarly, we calculate the sample proportion for the remaining trials.

Trial 1: p^ = 3/4 = 0.75

Trial 2: p^ = 2/4 = 0.5

Trial 3: p^ = 4/4 = 1.0

Trial 4: p^ = 1/4 = 0.25

Trial 5: p^ = 2/4 = 0.5

Trial 6: p^ = 3/4 = 0.75

Trial 7: p^ = 0/4 = 0.0

Trial 8: p^ = 4/4 = 1.0

Trial 9: p^ = 3/4 = 0.75

Trial 10: p^ = 4/4 = 1.0

In this way, we calculate the sample proportion for each trial, representing the proportion of heads observed. The sample proportions can range from 0 to 1, indicating the variability in the outcomes of flipping a coin.

The first four nonzero terms of the Maclaurin series for the function g(x) are:

1 - x + 1/2 x^2 - 1/6 x^3

So the correct answer is option (c).

To find the Maclaurin series for the given function g(x) = (1 + x)e^(-x), we can use the formula for the Maclaurin series:

f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...

First, we find the first few derivatives of g(x):

g(x) = (1 + x)e^(-x)

g'(x) = -xe^(-x) + e^(-x)

g''(x) = xe^(-x) - 2e^(-x)

g'''(x) = -xe^(-x) + 3e^(-x)

Evaluating these derivatives at x = 0, we get:

g(0) = 1

g'(0) = 0

g''(0) = -2

g'''(0) = 3

Using the Maclaurin series formula and substituting in these values, we get:

g(x) = 1 + 0x - 2/2! x^2 + 3/3! x^3 + ...

Simplifying this expression, we get:

g(x) = 1 - x + 1/2 x^2 - 1/6 x^3 + ...

Therefore, the first four nonzero terms of the Maclaurin series for the function g(x) are:

There are four possible three-letter arrangements that Amy can form using the letters from the word "dice" without repeating any letters. To form a three-letter arrangement using only letters from the word "dice" without repeating any letters, we can use the formula for combinations.

The formula is given by nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be chosen.
In this case, n = 4 (the total number of available letters) and r = 3 (the number of letters to be chosen for the arrangement).
5. Substituting these values into the formula, we get \(4C_{3}\) = 4! / (3!(4-3)!) = 4! / (3!1!) = (4 * 3 * 2) / (3 * 2 * 1) = 4.

If a Pearson correlation coefficient has a final value of +10, interpretation of this result is that it is an impossible value of r. Therefore, the correct option is A.

It is given that the Pearson correlation coefficient you calculated has a value of +10. This is actually an impossible value of r. Pearson correlation coefficient (r) ranges between -1 and +1. A value of +1 indicates a perfect positive correlation, while a value of -1 indicates a perfect negative correlation. A value of 0 suggests no correlation between the variables.

A value of +10 would fall outside of this range, making it an impossible value of r. Therefore, this result cannot be interpreted in terms of positive or negative correlation, nor can it be considered a significant correlation. It is important to ensure that the range of possible values is considered when interpreting statistical results. Hence, the correct answer is option A.

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.

One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.

In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior. By doing so, they can make more accurate forecasts and improve their overall performance.

Shape of Triangular sail is Obtuse Angled Triangle.

Step-by-step explanation:

The triangle is obtuse since the sum of the squares of 2 sides are greater than the square of the third side. (Converse Pythagorean theorem) Hope this helps!

Given: Length of sides of triangular sail = 7 ft , 15 ft , 7 ft

To find: Shape of Sail .i.e., shape of triangle

We use a result which states that

if a , b  , c are sides of triangle where c is greater then a & b.

now, if c² < a² + b² then triangle is Acute angled

if c² = a² + b² then triangle is Right angled

if c² > a² + b² then triangle is Obtuse angled

here a = 7 , b = 7 &  c = 15

c² = 15² = 225

a² + b² = 7² + 7² = 49 + 49 = 98

since, c² > a² + b²

⇒ Triangle must be Obtuse Angled.

Therefore, Shape of Triangular sail is Obtuse Angled Triangle.

4a) 32.90975

4b) 57.376406

5) 59.0362434

Step-by-step explanation:

4a)

Using trig functions, we can use tan to solve 4a

tan(35)=\(\frac{x}{47}\)

for tan, it is the opposite side of the angle as the numerator and the denominator is the adjacent leg

x = 32.90975

4b)

Same for this one, but cos

cos(35) = \(\frac{47}{x}\)

For cos, it is the adjacent side as the numerator and the hypotenuse as denominator.

5)

For this one, x is actually equal to the angle of depression

we can also use the tan function for this one

tan(x) = \(\frac{50}{30}\)

and solve for x:

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.

Answer:

your equation is false

The dimensions are 24 by 13.5 cm

The given parameters are

Length = 3 cm less than twice the width

This means that

L = 2W - 3

Where

L represents Length and W represents Width

The perimeter is given as

P = 75 cm

The perimeter is calculated as

P = 2*(L + W)

So, we have

2*(L + W) = 75

This gives

2*(2W - 3 + W) = 75

Evaluate

2*(3W - 3) = 75

Divide by 2

3W - 3 = 37.5

So, we have

3W = 40.5

Divide by 3

W = 13.5

Recall that

L = 2W - 3

So, we have

L = 2 * 13.5 - 3

Evaluate

L = 24

Hence, the dimensions of the rectangle are 24 by 13.5 cm
