Answer: F

Step-by-step explanation:

Answer: correct answer is A

Step-by-step explanation:

Remember that the coordinates (−2,−5π3) tell us the radius r=−2 and the angle θ=−5π3. So the point should be on the circle labeled 2 and form an angle of −5π3 with the negative x-axis. Point A is the correct point.

a. The shape of the sampling distribution is normal by the Central Limit Theorem.

b. The mean is 0.23.

c. The standard error is 0.125, which means that the sample proportions differ by around 0.125 from the mean of 0.23.

d. The probability is 0.2877 = 28.77%.

By the Central Limit Theorem, each sample has at least 10 successes and at least 10 failures, and the shape of the distribution is normal.

For each sample, the mean and the standard error are specified as follows:

Hence, the distribution of differences, the mean, and the standard error are specified as follows:

Using the z-score formula, the probability that the difference is greater than 30 is 1 subtracted by the p-value of Z when X = 0.3, Therefore:

Z = (0.3 - 0.23)/0.125

Z = 0.56

Z = 0.56

1 - 0.7123 = 0.2877 = 28.77%.

Permutation and combination:

Permutation is the act of arranging objects or numbers in order.

Composition is the selection of objects or numbers from a group of objects or collections, the order of the objects being unimportant.

According to the Question:

Arranging elements in a specific order is called permutation. Here, the components of the collection are organized in a linear or sequential fashion. For example, the permutation of the set A=1,6 is 2, which is 1,6,1. Unlike composition, where the order of the parts does not matter, permutation requires the elements to be in a specific order.

Answer: 1/864 =0.00116

Step-by-step explanation: simplify 3/8

divide 3/8 by 5= 3/40

3/40 divided by 24 =1/720

10/27 X 1/320= 1/864

simplify 10/27 and get 1/864 as a fraction but in a decimal 0.00116

The value of the expression 0 /27 ×((3/8 )÷ (5/24))  using division of fractions is 2/3

For dividing two fractions we keep the first one as it is and replace the sign of division by multiplication and take the reciprocal of the second number .

For example if we want to divide (a/b) by (c/d)

Then we write its as (a/b) ÷(c/d) = (a/b) × (d/c)

For evaluating the expression 10 /27 ×((3/8 )/ (5/24))

First evaluate (3/8 divided by 5/24)

(3/8)÷(5/24) = (3/8)×(24/5) = (3 ×24)/(8×5) =9/5

Now,

10 /27 ×((3/8 )/ (5/24)) =( 10/27 )× (9/5) = (10×9)/(27×5) = 2/3

Therefore, the value of the expression 10/27 x (3/8 divided by 5/24)  is 2/3.

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.

Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.

This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.

He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.

Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.

Thus, looking at the provided options, option B ($850.00) would be the correct answer.

Anna's total profit was $6000 + $16000 - $4000 = $14000.

How did Anna earn profit

Anna bought $4000 of company stock. The value of the stock doubled when she sold 75% of it, which means she sold 0.75 * $4000 = $3000 worth of stock when its value doubled.

Since the value of the stock doubled, Anna sold the $3000 worth of stock for 2 * $3000 = $6000.

Anna then sold the remainder of the stock (25% of the original amount) for four times the purchase price. Since she originally bought the stock for $4000, the remainder was worth 0.25 * $4000 = $1000.

Selling this remainder for four times the purchase price means that Anna sold it for 4 * $4000 = $16000.

We're given:

If the shop sold " \(9\dfrac{9}{10}\)  times as much milk chocolate as white chocolate", we must multiply \(9\dfrac{9}{10}\) by the amount of white chocolate sold to find the amount of milk chocolate sold.

Multiply \(9\dfrac{9}{10}\) by 9 ounces:

\(9\dfrac{9}{10}\times9\)

Convert the fraction into an improper fraction:

\(=\dfrac{99}{10}\times9\)

Multiply:

\(=\dfrac{891}{10}\)

The shop sold \(\dfrac{891}{10}\) ounces of milk chocolate.

Answer:

\(5x-y+7z-38=0\)

or

\(5x-y+7z=38\)

Step-by-step explanation:

Given vector equation:

\(\textbf{r} = \textbf{i} - 5\textbf{j} + 4\textbf{k} + \lambda(3\textbf{i} + \textbf{j} - 2\textbf{k}) + \mu(-\textbf{i} + 2\textbf{j} + \textbf{k})\)

The vector 3i + j - 2k is perpendicular to n.

The vector -i + 2j + k is perpendicular to n.

\(\textsf{So}\;\;\textbf{n}=\left|\begin{array}{ccc}\textbf{i}&\textbf{j}&\textbf{k}\\3&1&-2\\-1&2&1\end{array}\right|\)

        \(=\textbf{i}\left|\begin{array}{rr}1&-2\\2&1\end{array}\right|-\textbf{j}\left|\begin{array}{rr}3&-2\\-1&1\end{array}\right|+\textbf{k}\left|\begin{array}{rr}3&1\\-1&2\end{array}\right|\)

        \(=\textbf{i}(1 \cdot 1 - (-2) \cdot 2)-\textbf{j}(3 \cdot 1-(-2) \cdot (-1))+\textbf{k}(3 \cdot 2-1 \cdot (-1))\)

        \(=\textbf{i}(1 +4)-\textbf{j}(3-2)+\textbf{k}(6+1)\)

        \(=5\textbf{i}-\textbf{j}+7\textbf{k}\)

So the equation of the plane written in Cartesian form is:

\(5x-y+7z+d=0\)

Substituting (1, -5, 4) gives:

\(5(1)-(-5)+7(4)+d=0\)

\(5+5+28+d=0\)

\(38+d=0\)

\(d=-38\)

Therefore, the given vector equation in Cartesian form is:

Answer:

y - 1/3x - 10 + 4 = 0

Step-by-step explanation:

What we know:

x = 12

y = 10

slope (m) = 1/3

y - y1 = m(x - x1) Point-slope form

Substitute in the values we have

y - 10 = 1/3(x - 12)

Bring all the values to one side

y - 10 - 1/3(x - 12) = 0

y - 1/3x - 10 + 4 = 0

The perimeter and area of the rectangle with given vertices are  24 units and the area is 27 square units.

To find the perimeter and area of the rectangle with the given vertices, we can use the distance formula and the formula for rectangle area.

First, let's find the lengths of the sides using the distance formula:

Side AB: √[(x₂ - x₁)² + (y₂ - y₁)²]

         = √[(5 - 5)² + (-3 - 6)²]

         = √[0² + (-9)²]

         = √81

         = 9

Side BC: √[(x₂ - x₁)² + (y₂ - y₁)²]

         = √[(2 - 5)² + (-3 - (-3))²]

         = √[-3² + 0²]

         = √9

         = 3

Now, we can calculate the perimeter by adding the lengths of all four sides:

Perimeter = AB + BC + CD + DA

         = 9 + 3 + 9 + 3

         = 24

To find the area of the rectangle, we can use the formula:

Area = Length × Width

The length of the rectangle is AB = 9 and the width is BC = 3.

Area = 9 × 3

        = 27

Therefore, the perimeter of the rectangle is 24 units and the area is 27 square units.

Step-by-step explanation:

When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.

The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.

Replacing x with 1, we have:

ƒ(1) = -4(1) - 5

Simplifying further:

ƒ(1) = -4 - 5

ƒ(1) = -9

Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.

Let's break down the steps taken to arrive at the solution:

1. Start with the function f(x) = -4x - 5.

2. Replace x with 1 in the function.

3. Evaluate the expression by performing the necessary operations.

4. Simplify the expression to obtain the final result.

In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.

It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.

Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.
