The equation 6x + 5 = 5x + 11 +x-6 is true for all real numbers. Substitute a few real numbers for x to see that this is so and then try solving the equation. Describe
what happens.

A - B is the complement of B in A; in other words, all the elements of A that do not belong to B.

Since A ∩ B = {4, 6}, we have

A - B = {2, 8, 10}

Then the complement of A - B, denoted (A - B)' is all the elements of the universal set U that do not belong to A - B.

(A - B)' = {1, 3, 4, 5, 6, 7, 9}

Step-by-step explanation:

1) Simplify 4² to 16.

\( \frac{ - \frac{1}{3} \times - 33 - \frac{1}{2} \times 16 }{ \frac{1}{4} } \)

2) Move the negative sing to the left side.

\( \frac{ - ( - \frac{33}{3}) - \frac{1}{2} \times 16 }{ \frac{1}{4} } \)

3) Simplify 33/3 to 11.

\( \frac{ - ( - 11) - \frac{1}{2} \times 16 }{ \frac{1}{4} } \)

4) Simplify 1/2 × 16 to 16/2.

\( \frac{ - ( - 11) - \frac{16}{2} }{ \frac{1}{4} } \)

5) Simplify 16/2 to 8.

\( \frac{ - ( - 11) - 8}{ \frac{1}{4} } \)

6) Remove parentheses.

\( \frac{11 - 8}{ \frac{1}{4} } \)

7) Simplify 11 - 3 to 8.

\( \frac{3}{ \frac{1}{4} } \)

8) Invert and multiply.

Answer:

√38

Step-by-step explanation:

√38

step 1: Check which squared numbers can be multiplied by another number to get 38.

Start with these numbers: 4, 9, 16, and 25

Step 2: Testing out the numbers

√25 × __ = 25 can't be divided by 38

√16 × ___ = 16 can't be divided by 38

√9 × ____ = 9 can't be divided by 38

√4 × ____= 4 can't be divided by 38

Step 3: Answer

After trying the square root numbers that could possibly work with √38 none work; which means √38 can't be simplified. So the answer is √38

Answer: Adams heart Beats 1,440 more times than Blake’s in 120 minutes.

Step-by-step explanation:

Adam: 74 x 120 = 8,880

Blake: 62 x 120 = 7,440

8,880 - 7,440 = 1,440

Answer:

1440

Step-by-step explanation: you multiply

74 x 120 and 62 x 120

8,880             7,440 then subtract the two

8,880 - 7,740 = 1,440

Answer:

Answer: 52.4 percent

Step-by-step explanation: So you'd want to subtract 7.80 from 16.40 to get 8.60. Then you'd multiply that by 100 which would give you 860. After you've done that you want to divide 860 by 16.40.

Answer:

A. can I come anwser my question

C. No, because a difference in proportions of 0.4 or more occurred 7 out of 200 times, meaning the difference is not statistically significant and the new additive is not more effective.

====================================================

Explanation:

If the new additive was more effective than the old one, then the difference in proportions (new - old) should be fairly large.

Count the dots over the x axis labels of "0.4" through "0.6"

That makes 5+1+1 = 7 dots total.

There are 7 instances where the difference of proportions is 0.4 or larger.

This is out of 200 observations, so 7/200 = 0.035 = 3.5% of the differences have 0.4 or larger.

This is not very significant. The general rule of thumb is to use 5% as the threshold. Some stats textbooks will use 10%. Other times your teacher will specify the significance level. The Greek letter alpha is often used.

Because 3.5% < 5%, we consider the new additive to not be that effective compared to the original additive.

Answer:

2744m^3

Step-by-step explanation:

14*14*14=2744m^3

Answer:

50mb

Step-by-step explanation:

So start with what you have 300/150 = 2 so each song took up 2mb of space, so 25 songs would take up 25x2= 50mb

The number of megabytes taken up by 25 songs is 50 megabytes.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

150 songs = 300 megabytes

1 song = 300 /150 megabytes

1 song = 2 megabytes ______(1)

Now,

Multiply 25 on both sides of (1).

25 songs = 25 x 2 megabytes

25 songs = 50 megabytes

Thus,

25 songs will take 50 megabytes.

Answer:

Step-by-step explanation:

We can use the method of undetermined coefficients to solve this differential equation. First, we will need to find the solution to the homogeneous equation and the particular solution to the non-homogeneous equation.

For the homogeneous equation, we will use the form y"+ky=0, where k is a constant. We can find the solutions to this equation by letting y=e^mx,

y"=m^2e^mx -> (m^2)e^mx+k*e^mx=0, therefore (m^2+k)e^mx=0

(m^2+k) should equal 0 for the equation to have a non-trivial solution. Therefore, m=±i√(k), and the general solution to the homogenous equation is y=A*e^i√(k)x+Be^-i√(k)*x.

Now, we need to find the particular solution to the non-homogeneous equation. We can use the method of undetermined coefficients to find the particular solution. We will let yp=a0+a1x+a2x^2+.... As the derivative of a sum of functions is the sum of the derivatives, we get

yp″=a1+2a2x....yp‴=2a2+3a3x+....

Substituting the general solution into the non-homogeneous equation, we get

a0+a1x+a2x^2+...+2a2x+3a3x^2+...=Y(4)

So, the coefficient of each term in the expansion of the left hand side should equal the coefficient of each term in the expansion of the right hand side. Since there is only one term on the right hand side, we get the recurrence relation:

a(n+1)=Y(n-2)/n^2

From this relation, we can find all the coefficients in the expansion for the particular solution. Using this particular solution, we can find the total solution to the differential equation as the sum of the homogeneous solution and the particular solution.

The probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.78.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that the statistics class has 50 students and among those students, 35 are business majors, and 7 like grilled cheese. Of the business majors, 3 like grilled cheese.

The probability will be calculated as:-

P(AUB) = P(A) + P(B) - P(AB)

\(P(AUB)=\dfrac{35}{50}+\dfrac{7}{50}-\dfrac{3}{50}\)

\(P(AUB)=\dfrac{42-3}{50}\)

\(P(AUB)=\dfrac{39}{50}\)

P(AUB) = 0.78

Therefore the probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.78.

Step-by-step explanation:

This would be more of an opinion and not a fact, but I see it as very unlikely that they will be able to accomplish this goal. Mainly due to human psychology. Most individuals want to be able to physically hold their money as well as being able to physically exchange their money for the goods that they need since physical cash is accepted worldwide.

Step-by-step explanation:

Answer:

a) There are four prime numbers between 1 and 10: 2, 3, 5, and 7. So the probability of drawing a prime number is 4/10 or 2/5, which is 20% and not 10%. Therefore, option (a) is not correct.

b) As we saw in part (a), the probability of drawing a prime number is 2/5 or 40% (since 2/5 is equivalent to 0.4). Therefore, option (b) is correct.

c) The probability of drawing a prime number is 2/5 or 40%, which is not 25%. Therefore, option (c) is not correct.

d) As we saw in part (a) and (b), the probability of drawing a prime number is 2/5 or 40%, which is not 50%. Therefore, option (d) is not correct.

So, the correct answer is (b) 25%.

Answer:

Mean = 59.1, Median = 61

(there might have been a mistake in calculation (a lot of numbers!))

Step-by-step explanation:

The sample size is 40,

Now, the formula for the mean is,

Mean = (sum of the sample values)/(sample size)

so we get,

\(Mean = (49+63+78+22+41+39+75+61+63+65+58+37+45+52+81+75+78+72+68+59+72+85+63+61+75+39+41+48+59+55+61+25+61+52+58+71+75+82+49+51)/40\\Mean = 2364/40\\Mean = 59.1\)

To find the median, we have to sort the list in ascending (or descending)order,

we get the list,

22,25,37,39,39,41,41,45,48,49,

49,51,52, 52,55,58, 58, 59, 59, 61,

61, 61, 61, 63, 63, 63, 65, 68, 71, 72,

72, 75, 75, 75, 75, 78, 78, 81, 82, 85

Now, we have to find the median,

since there are 40 values, we divide by 2 to get, 40/2 = 20

now, to find the median, we takethe average of the values above and below this value,

\(Median = ((n/2+1)th \ value + (n/2)th \ value )/2\\where, \ the\ (n/2)th \ value \ is,\\n/2 = (total \ number \ of \ samples) /2\\n/2=40/2\\(n/2)th = 20\\Hence\ the (n/2)th \ value \ is \ the \ 20th \ value\)

And the (n+1)th value is the 21st value

Now,

The ((n/2)+1)th value is 61 and the nth value is 61, so the median is,

Median = (61+61)/2

Median = 61

Answer:

\(sin(\theta) = \frac{\sqrt{17} }{7}\)

Step-by-step explanation:

We know that:

sin(x)^2 + cos(x)^2 = 1

And we know that:

\(cos(\theta) = \frac{4\sqrt{2}}{7} }\)

We want to find the value of the sine function evaluated in theta.

If we replace that in the first equation, we get:

\(sin(\theta)^2 + cos(\theta)^2 = 1\)

\(sin(\theta)^2 + (\frac{4*\sqrt{2} }{7}) ^2 = 1\)

\(sin(\theta)^2 + (\frac{4^2*\sqrt{2}^2 }{7^2}) = 1\)

\(sin(\theta)^2 + (\frac{16*2 }{49}) = 1\)

Now we can just isolate the sine part of that equation, so we get:

\(sin(\theta)^2 = - (\frac{16*2 }{49}) + 1 = \frac{-32}{49} + \frac{49}{49} = \frac{-32 + 49}{49} = \frac{17}{49}\)

\(sin(\theta) = \sqrt{\frac{17}{49} } = \frac{\sqrt{17} }{\sqrt{49} } = \frac{\sqrt{17} }{7}\)

(We can't simplify the fraction anymore)

The slope between the two points is 7/4

Step-by-step explanation:

Slope  of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\(\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\)

The points plotted by Carlos are (-4,-4) and (0,3), thus the slope is:

\(\displaystyle m=\frac{3-(-4)}{0-(-4)}\)

\(\displaystyle m=\frac{7}{4}\)

The slope between the two points is 7/4
