What is common ratio?

The common ratio between consecutive terms in a geometric sequence is constant. Let's denote this common ratio by 'r'. To find 'r', we can divide any term by the preceding term,

r = -448/896 = -1/2

Now we can use the formula for the nth term of a geometric sequence,

[tex]a_n = a_1 \times p^{n - 1}[/tex]

where '

[tex]a_1[/tex] is the first term and 'n' is the index of the term we want to find.

Substituting the values we have,

[tex]a_8 = 896 (-1/2)^{8-1} \\ = 896 \times (-1/2)^{7} = -14[/tex]

Therefore, the eighth term of the sequence is -14.

Experimental Probability:

The experimental probability of an event is found by dividing the number of times the event occurs by the total number of trials. In this case, the name Grace was chosen 15 times out of 116 trials, so the experimental probability of choosing Grace is:

Experimental Probability = Number of times Grace was chosen / Total number of trials

Experimental Probability = 15 / 116

Experimental Probability = 0.1293 or approximately 12.93%

Theoretical Probability:

The theoretical probability of an event is found by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, there are six names in the hat, so the probability of choosing Grace is:

Theoretical Probability = Number of favorable outcomes / Total number of possible outcomes

Theoretical Probability = 1 / 6

Theoretical Probability = 0.1667 or approximately 16.67%

If the number of names in the hat were different, both the experimental and theoretical probabilities would change. For example, if there were only three names in the hat, the theoretical probability of choosing Grace would be 1/3 or approximately 33.33%. The experimental probability would also change based on the number of times Grace was chosen out of the total number of trials. As the number of names in the hat increases, the theoretical probability of choosing Grace decreases, and the experimental probability becomes more accurate as the number of trials increases.

The solution to the trigonometric equation with sine function is x = 2.5.

Starting with 3√2 sin π/3 (x − 2) + 4 = 7:

First, we can simplify 3√2 sin π/3 to 3, since sin π/3 = √3/2 and 3√2 = 3 x √2 x √2 = 3 x 2 = 6.

6(x - 2) + 4 = 7

6x - 12 + 4 = 7

6x - 8 = 7

6x = 15

x = 2.5

Answer:

Step-by-step explanation:

y = x² - 4x - 5 → (1)

y = x - 9 → (2)

substitute y = x² - 4x - 5 into (2)

x² - 4x - 5 = x - 9 ( subtract x - 9 from both sides )

x² - 5x + 4 = 0 ← in standard form

(x - 1)(x - 4) = 0 ← in factored form

equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 4 = 0 ⇒ x = 4

substitute these values into (2) for corresponding values of y

x = 1 : y = 1 - 9 = - 8 ⇒ (1, - 8 )

x = 4 : y = 4 - 9 = - 5 ⇒ (4, - 5 )

A prism is a three-dimensional geometric shape that consists of two identical polygonal bases that are connected by a set of parallelogram faces. The shape of the prism is determined by the shape of its bases. For example, if the bases are triangles, the prism is called a triangular prism. Similarly, if the bases are squares, the prism is called a square prism, and so on.

Prisms have a number of interesting properties. The faces that connect the bases are always parallelograms, and the opposite faces are congruent and parallel. The altitude of a prism is the perpendicular distance between its bases, and its lateral faces are all rectangles or parallelograms. The volume of a prism can be calculated by multiplying the area of its base by its altitude. The formula for the volume of a prism is V = Bh, where V is the volume, B is the area of the base, and h is the altitude.

Given:

Length of the rectangular prism, l = 12 in

The probability that the random variable has a value between 0.1 and 3.3 is 0.0256. Option b is correct answer.

Since the area under the density curve represents the total probability, we need to find the area between the vertical lines at x = 0.1 and x = 3.3, and under the curve.

First, we need to find the y-coordinates of the two horizontal lines. The line passing through (0, 125) and (8, 125) is parallel to the x-axis, so it has a constant y-coordinate of 125. The line passing through (8, 0) and (8, 125) is parallel to the y-axis, so it has an undefined slope and is a vertical line.

Therefore, we do not need to find its y-coordinate.

Next, we need to find the equation of the density curve. Since it is a uniform density curve, the height of the curve is constant over its entire length.

To find the height, we need to find the total area under the curve, which is given by the rectangle formed by the vertical lines at x = 0 and x = 8, and the horizontal lines at y = 0 and y = 125.

The width of the rectangle is 8, and the height is 1/125 (since the total area is 1 and the width is 8). Therefore, the height of the curve is 1/125 over its entire length.

Now, we can find the area between the vertical lines at x = 0.1 and x = 3.3, and under the curve.

The width of this area is 3.3 - 0.1 = 3.2, and the height of the curve is 1/125. Therefore, the area is:

3.2 × (1/125) = 0.0256

Therefore, the probability that the random variable has a value between 0.1 and 3.3 is 0.0256.

a) We can rewrite the provided line in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, to determine the slope.

y + 1 = (5/7)(x - 4) (x - 4)

y = (5/7)x - (20/7) - 1

y = (5/7)x - (27/7)

This line and the one we're looking for are parallel, thus their slopes are the same (5/7). Hence, the equation of the line passing through E(4,-3) can be expressed using the point-slope form:

y - (-3) = (5/7)(x - 4) (x - 4)

y = (5/7)x - (20/7)

To find out how much more Khalil's cat weighed than Sophia's cat, we need to subtract the weight of Sophia's cat from the weight of Khalil's cat.

Khalil's cat weighed 18 5/6 pounds.

Sophia's cat weighed 10 1/3 pounds.

Subtracting the weights:

18 5/6 - 10 1/3

To subtract mixed numbers, we need to find a common denominator. In this case, the least common multiple of 6 and 3 is 6. So, we can convert the fractions to have a denominator of 6:

18 5/6 - 10 1/3 = 18 5/6 - 10 2/6

Now, we can subtract the whole numbers and the fractions separately:

18 - 10 = 8

5/6 - 2/6 = 3/6

Step-by-step explanation:

Since the altitude drawn from the vertex of the isosceles triangle forms two congruent right triangles and divides the base into two equal segments, we can work with one of the right triangles to find the length of the other side of the isosceles triangle.

Let's denote the length of the altitude as a, the length of half the base as b, and the length of the other side of the isosceles triangle as c. From the problem, we know that a = 18 inches and b = 15 inches / 2 = 7.5 inches.

We can use the Pythagorean theorem to find the length of c:

a² + b² = c²

Substitute the known values:

18² + 7.5² = c²

324 + 56.25 = c²

380.25 = c²

Now, take the square root of both sides to find the length of c:

c = √380.25

c ≈ 19.5 inches

Since the isosceles triangle has two sides with equal length, the perimeter is:

Perimeter = base + 2 * c

Perimeter = 15 + 2 * 19.5

Perimeter = 15 + 39

Perimeter = 54 inches

Thus, the perimeter of the isosceles triangle is approximately 54 inches.

Given that ABCD is a parallelogram:

Opposite sides of a parallelogram are parallel and congruent. Therefore, AB = DC.

Diagonals of a parallelogram bisect each other. Therefore, the midpoint of AC is the same as the midpoint of BD. Let M be the midpoint of AC, and N be the midpoint of BD.

By the midpoint theorem, BM = DM and BN = AN.

Since BM = DM and BN = AN, we can conclude that quadrilateral ABCD is a parallelogram in which BC || AD and CD || AB.

Therefore, we have shown that AB = CD and BC = AD in parallelogram ABCD.

Step-by-step explanation:

Set the two equal to each other:

5x=3x+46

Step-by-step explanation:

We are given:

Sample size (n) = 35

Sample mean ($\bar{x}$) = 36 seconds

Population standard deviation ($\sigma$) = 8 seconds

Confidence level = 95%

We can find the margin of error using the formula:

Margin of Error = z*(σ/√n), where z is the z-score for the given confidence level, σ is the population standard deviation, and n is the sample size.

For a 95% confidence level, the z-score is 1.96 (from the z-table or calculator).

Putting the values in the formula, we get:

Margin of Error = 1.96*(8/√35) ≈ 2.68

The confidence interval is given by:

Lower Limit = $\bar{x}$ - Margin of Error

Upper Limit = $\bar{x}$ + Margin of Error

Substituting the values, we get:

Lower Limit = 36 - 2.68 ≈ 33.32

Upper Limit = 36 + 2.68 ≈ 38.68

Therefore, the 95% confidence interval for the mean time that all half-hour local TV news broadcasts devote to U.S. foreign policy is (33.32, 38.68).

Since the Lear Center's claim of the average time being 38 seconds falls within this interval, we can say that the sample data supports the Lear Center's claim at a 95% confidence level.
