Answer:

x = 10°

Step-by-step explanation:

As we can see it is an equilateral triangle so all sides and angles are equal.

6x + 6x + 6x = 180° { being sum of angles of triangle }

18x = 180°

x = 180° / 18

x = 10°

Hope it will help ✔

Hey there

Answer:

10°

Step-by-step explanation:

Since all sides are equal.

Then,

It is the equilateral triangle

Therefore,

All sides are equal to 60°

Now,

60° = 6x

60°/6 = x

10° = x

Answer:

The Answer is the bottom one

a) A sample size of at least 963 drivers is needed.

b) A sample size of at least 753 drivers is needed.

a) To determine the sample size needed for a 90% confidence interval with a margin of error of 3%, we need to use the formula:

\(n = (z^2 \times p \times q) / E^2\)

Where:

n = sample size

z = the z-score corresponding to the desired confidence level (in this case, 1.645 for 90%)

p = the estimated proportion of drivers exceeding the speed limit (unknown)

q = 1 - p

E = the margin of error (0.03)

To find the minimum sample size required, we need to estimate p. Since we do not have any previous information, we can use 0.5 as an estimate, which gives:

\(n = (1.645^2 \times 0.5 \times 0.5) / 0.03^2 = 962.59\)

b) If previous studies found that 80% of drivers on this road exceeded the speed limit, we can use this value as an estimate for p in the formula above:

\(n = (1.645^2 \times 0.8 \times 0.2) / 0.03^2 = 752.45\)

The answer to part (b) is (D) 753.

Answer:

43 1/3 minutes to iron 10 shirts

Step-by-step explanation:

Number of shirts : Time taken

3 shirts : 13 minutes

10 shirts : x minutes

3 / 13 = 10 / x

Cross product

3 * x = 13 * 10

3x = 130

Divide both sides by 3

3x / 3 = 130 / 3

x = 43 1/3 minutes

x = 43 minutes 20 seconds

It will take 43 minutes 20 seconds to iron 10 shirts

The correct statements are: A) The distance between point A and point K is 8.2 units. C) The distance between point G and point B is 10.8 units. E) The distance between point P and point E is 13.2 units.

To find the distance between two points using the Pythagorean Theorem, we need to consider the coordinates of the points and calculate the length of the hypotenuse of the right triangle formed by connecting the points. The distance between point A and point K: Given the coordinates of point A as (4, 3) and point K as (8, 9), we can calculate the distance using the Pythagorean Theorem. The horizontal distance is 8 - 4 = 4 units, and the vertical distance is 9 - 3 = 6 units. The distance is √((4^2) + (6^2)) ≈ 8.2 units.

The distance between point G and point B: Given the coordinates of point G as (5, 1) and point B as (9, 10), the horizontal distance is 9 - 5 = 4 units, and the vertical distance is 10 - 1 = 9 units. The distance is √((4^2) + (9^2)) ≈ 10.8 units. The distance between point P and point E: Given the coordinates of point P as (6, 2) and point E as (2, 10), the horizontal distance is 6 - 2 = 4 units, and the vertical distance is 10 - 2 = 8 units. The distance is √((4^2) + (8^2)) ≈ 13.2 units. Therefore, the correct statements are A) The distance between point A and point K is 8.2 units, C) The distance between point G and point B is 10.8 units, and E) The distance between point P and point E is 13.2 units.

y=1/3x+4 is the equation of line passing through (3, 5) and parallel to -x+3y=6

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

-x+3y=6

3y=6+x

Divide both sides by 3

y=2+1/3x

y=1/3x+2

slope is 1/3

In parallel lines the slope will remain same

We need to find the equation of line passing through (3, 5) and parallel to 3y=6+x

5=1/3(3)+b

5=1+b

Based on the given information, we can assume that AB and AD are line segments in a two-dimensional plane. AB is 10 inches in length while AD is 6 inches in length. These measurements provide us with two important pieces of information that can be used for various calculations.

For instance, we can use the given lengths to find the distance between points A and B. This can be done using the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse (the longest side). So, we can assume that AB is the hypotenuse of a right triangle with sides AB and AD. Using the Pythagorean Theorem, we can find the length of the third side (AC): AC^2 = AB^2 - AD^2 = 100 - 36 = 64. Thus, AC = 8 inches.

Overall, the given measurements of AB and AD provide us with a foundation for solving various geometric problems and making calculations in a two-dimensional plane.

This is a more complicated way to write \(y < 2\)

The range is the set of all possible y outputs of a function. So we use the graph to see what y values are possible. The graph shows that y can be anything smaller than y = 2. We can't actually reach y = 2 itself due to a horizontal asymptote here.

In interval notation, the answer would be \((-\infty, 2)\) with the curved parenthesis to indicate "do not include y = 2 as part of the range".

Parity check matrix is a mathematical construct that verifies the accuracy of digital information. To prove that the parity check matrix has the characteristic of "all columns are distinct," we need to show that no two columns in the matrix are the same. This can be proven by contradiction.

Assume that there exist two columns in the parity check matrix that are the same. Let's denote these columns as Column X and Column Y,

where X ≠ Y.

Since the columns are the same, all the elements in Column X are equal to the corresponding elements in Column Y.

Now, let's consider the corresponding rows in the matrix for Column X and Column Y. Since all the elements in these columns are the same, the corresponding elements in the rows will also be the same. However, this contradicts the definition of a parity check matrix.

A parity check matrix is constructed in such a way that each column represents a different parity check equation. If two columns are the same, it means that they represent the same parity check equation.

This would violate the requirement of a parity check matrix, which states that each parity check equation should be distinct.

Therefore, by contradiction, we can conclude that the parity check matrix has the characteristic of "all columns are distinct."

We have two events, A and B, with P(A) = 0.60, P(B) = 0.70, and P(An B) = 0.40: a. P(A/B) = 0.5714 and b. P(B/A) = 0.6667

a. P(A/B) = 0.5714

To find P(A/B), we use the formula for conditional probability: P(A/B) = P(An B) / P(B).

Given that P(An B) = 0.40 and P(B) = 0.70, we can substitute these values into the formula:

P(A/B) = 0.40 / 0.70 = 0.5714 (rounded to 4 decimal places).

b. P(B/A) = 0.6667

To find P(B/A), we use the formula for conditional probability: P(B/A) = P(Bn A) / P(A).

Given that P(An B) = 0.40 and P(A) = 0.60, we can calculate P(Bn A) by rearranging the formula: P(Bn A) = P(An B) * P(A) = 0.40 * 0.60 = 0.24.

Substituting these values into the formula, we have:

P(B/A) = P(Bn A) / P(A) = 0.24 / 0.60 = 0.6667 (rounded to 4 decimal places).

The value of b in the equation (x^2 + bx - 2)(x + 3) = x^3 + 6x^2 + 7x - 6 can be determined by comparing the coefficients of the corresponding terms on both sides of the equation. The value of b is 7.

To find the value of b, we expand the left side of the equation (x^2 + bx - 2)(x + 3) using the distributive property. This results in the expression x^3 + 3x^2 + bx^2 + 3bx - 2x - 6.

Comparing this expression with the right side of the equation x^3 + 6x^2 + 7x - 6, we can see that the coefficients of the corresponding terms should be equal. The coefficient of x^2 is 3 in both expressions, the coefficient of x is 7 in both expressions, and the constant term is -6 in both expressions. Therefore, the value of b is 7.

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = \(\frac{-36-(-6)}{4-(-1)}\) = \(\frac{-36+6}{4+1}\) = \(\frac{-30}{5}\) = - 6

Hi!

Your answer should be: 3/c, "c= (5)($7)"

Reason being:

A: it only has the number of tickets, so that wouldn't make sense.

B: It has both numbers, but, were not adding, because the tickets cost $7 EACH, so only adding them wouldn't give you the right answer.

C: They are multiplying 5x$7, which is correct because  each ticket is $7, and she is trying to buy 5, so 5x$7=c is correct.

D: like A, they only have one part of the problem, so it wouldn't make sense.

Hope this helps!

Yours truly,

Answer:

I did this in a test so the answer is the third one. i already knew the answer was the third one.

Step-by-step explanation:

Lets check all of em first.

c = 5

(c) cant equal five because (c) is the total cost for tickets and if she bought 5

and each of them is $7  it cant be 5 thes goes same for the other-  c = $7

Now for c = 5 + $7 Clearly you cant find out the total cost for 5 tickets using addition.

therefore, the right answer is c = (5) ($7)
