which expression uess exactly terms and is equivalent to 6(2 + x + x + y)

Answer:

the answer is 11.66

Step-by-step explanation:

because 3 cant give 0 anything 9 will make 1, 2 but 2 cant change 6

Answer:

11.66

Step-by-step explanation:

The thousandths (1) is less than 5. Round 1 to 0, so you'll get 11.66.

Therefore, the correct probability distribution for X is:

X P(X)

3 2/3

4 2/3

5 2/3

6 0

We can determine the probability distribution of X by listing all possible values of X and their corresponding probabilities:

X = 3: The only way to obtain a sum of 3 is by selecting balls (1,2) or (2,1), each with probability 1/3. Therefore, P(X=3) = 1/3 + 1/3 = 2/3.

X = 4: The only way to obtain a sum of 4 is by selecting balls (1,3) or (2,2), each with probability 1/3. Therefore, P(X=4) = 1/3 + 1/3 = 2/3.

X = 5: The only way to obtain a sum of 5 is by selecting balls (2,3) or (3,2), each with probability 1/3. Therefore, P(X=5) = 1/3 + 1/3 = 2/3.

X = 6: There is no way to obtain a sum of 6.

We can check that the sum of the probabilities for all possible values of X is 1:

P(X=3) + P(X=4) + P(X=5) + P(X=6) = 2/3 + 2/3 + 2/3 + 0 = 6/3 = 2

Therefore, the correct probability distribution for X is:

X P(X)

3 2/3

4 2/3

5 2/3

6 0

The correct statement regarding the residual in this problem is given as follows:

2.66; The line of best fit underpredicts the temperature change.

For a data-set, the definition of a residual is that it is the difference of the actual output value by the predicted output value, that is:

Residual = Observed - Predicted.

For a rain amount of 0.4 inches, the predicted temperature change is given as follows:

y = -1.4 x 0.4 + 0.2

y = -0.36.

Then the residual is given as follows:

R = 2.3 - (-0.36)

R = 2.66 -> underpredicts the change.

Answer:

C

Step-by-step explanation:

Area of a 1/4 sector of a circle = 1/4 * pi r^2

Givens

100 of these quarter sectors

pi = 3.14

r = 12

Solution

You are using area because you are going to paint each one of the sectors. You must cover every cm^2 with paint.

Area = 1/4 * 3.14 * r * r

Area = 1/4 * 3.14 * 12 * 12

Area = 113.25

But there are 100 of them. so the area is

100 * Area = 11325 cm^2

Rounded to the nearest 100 hundreds = 11300 cm^2

The answer is 11,300 cm²

Answer:

x = 16

Step-by-step explanation:

This is the answer because:

1) First, minus 4 from +4 and 20

+4 - 4 = 0

20 - 4 = 16

2) Now, you are left with x = 16

Therefore, the answer is x = 16. You can also check by adding 16 + 4 which equals to 20. This is how you solve for the variable by using addition property of equality.

Answer:

\(10d\geq 35\).

Step-by-step explanation:

Time for which Mikal volunteers each day \(=7\) hours.

Time spent on traveling each day \(=1.5+1.5=3\) hours.

Since the time spent on traveling also counts toward his community service hours.

So, total hours completed for the project each day \(=7+3=10\) hours.

Let \(d\) be the number of days, Mikal must volunteer at the park to complete his summer project.

Mikal must complete at least \(35\) hours of community service at a city park for the project.

So, \(10d\geq 35\) be the inequality that can be used to find the number of days Mikal must volunteer at the park to complete his summer project.

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.

u > 7

Step-by-step explanation:

-2u -6 < -20  Add 6 to both sides

-2u - 6 + 6 < -20 + 6

-2u < -14  Divide both sides by -2.  When you multiply or divide both sides by a negative number, you must flig the sign.

\(\frac{-2u}{-2}\) > \(\frac{-14}{-2}\)

u > 7

Helping in the name of Jesus.

The answer is:

u > 7

In-depth explanation:

You haven't told me what the values of u are, but I'll solve the equation for u.

Add 6 on each side:

\(\bf{-2u-6 < -20}\)

\(\bf{-2u < -14}\)

Divide each side by -1 and reverse the sign:

\(\bf{2u > 14}\)

Now divide each side by 2

\(\bf{u > 7}\)

The cost price of the article, which is sold for Rs. 150 at a gain but if sold for Rs. 135 would have resulted in a loss equal to 50% of the original gain, is Rs. 127.50.

The cost price is the difference between the selling price and the profit or gain.

The difference is determined by subtraction.

Selling price of the article = Rs. 150

Loss if sold at Rs. 135 = 50% of the original gain

Original gain = Rs. 15 (Rs. 150 - Rs. 135)

50% of the original gain = Rs. 7.50 (Rs. 15 x 50%)

Cost price of the article = Rs. 127.50 (Rs. 135 - Rs. 7.50)

Thus, the cost price is Rs. 127.50.
