The sum of the geometric series with 12 terms, starting from 10 and with a common ratio of 2, is 40,950.

To find the sum of a geometric series, we can use the formula:

S = a * (1 - r^n) / (1 - r)

Where:

S is the sum of the series,

a is the first term of the series,

r is the common ratio,

n is the number of terms in the series.

In this case, the first term (a) is 10, the common ratio (r) is 2, and the number of terms (n) is 12.

Plugging in the values into the formula, we have:

S = 10 * (1 - 2^12) / (1 - 2)

Simplifying further:

S = 10 * (1 - 4096) / (1 - 2)

S = 10 * (-4095) / (-1)

S = 10 * 4095

S = 40,950

Therefore, the sum of the geometric series with 12 terms, starting from 10 and with a common ratio of 2, is 40,950.

The correct answer is D) 40,950.

To calculate the perimeter, add the lengths of sides AB, BC, and AC. The area can be found using Heron's formula. To find the angles, use the law of cosines.

1. **Perimeter and area of triangle ABC**

To find the perimeter and area of triangle ABC, we need to use the given information about its sides and angles.

Let's assume that side AB has a length of "a", side BC has a length of "b", and side AC has a length of "c". The given angles are angle A, angle B, and angle C.

The perimeter of a triangle is the sum of the lengths of its sides. Therefore, the perimeter P of triangle ABC is given by: P = a + b + c.

To find the area of triangle ABC, we can use Heron's formula, which states that the area A of a triangle with side lengths "a", "b", and "c" is given by: A = √(s(s - a)(s - b)(s - c)), where s is the semi-perimeter of the triangle, given by: s = (a + b + c) / 2.

Once we have calculated the area, we can use the law of cosines to find the measures of the angles. The law of cosines states that for a triangle with side lengths "a", "b", and "c", and opposite angles A, B, and C, the following relationships hold:

cos(A) = (b^2 + c^2 - a^2) / (2bc)

cos(B) = (a^2 + c^2 - b^2) / (2ac)

cos(C) = (a^2 + b^2 - c^2) / (2ab)

Using these formulas, we can calculate the measures of the angles A, B, and C.

To find the exact values of the perimeter, area, and angles, we would need the specific lengths of the sides and the measures of the angles. Please provide those values, and I can assist you with the calculations.

For example, when x = 1, y = 2, and there are no other inputs with the same output. The set of ordered pairs {(1, 3), (2, 5), (1, 4)}: This is not a function because the input x = 1 has two different output values, y = 3 and y = 4. A function requires each input to have only one corresponding output. The equation y = x^2: This is a function because for every x-value, there is a unique y-value.

The probability mass function (PMF) for x is {0.0004, 0.0588, 0.3432, 0.941192}, and the cumulative mass function (CMF) for x is {0.0004, 0.0592, 0.4024, 1.0}.

The probability mass function (PMF) and cumulative mass function (CMF) for the random variable x, which denotes the number of parts correctly classified in an optical inspection system, can be determined.

Since the classifications of the parts are independent, we can use the binomial probability distribution to model this scenario. The PMF gives the probability of obtaining a specific value of x, and the CMF gives the probability of obtaining a value less than or equal to x.

The PMF of x is given by the binomial probability formula:

P(x) = (n C x) * p^x * (1 - p)^(n - x)

where n is the number of trials (number of parts inspected), x is the number of successes (number of parts correctly classified), and p is the probability of success (probability of correct classification of any part).

In this case, n = 3 (three parts inspected) and p = 0.98 (probability of correct classification).

Let's calculate the PMF for x:

P(x = 0) = (3 C 0) * (0.98^0) * (1 - 0.98)^(3 - 0) = 0.0004

P(x = 1) = (3 C 1) * (0.98^1) * (1 - 0.98)^(3 - 1) = 0.0588

P(x = 2) = (3 C 2) * (0.98^2) * (1 - 0.98)^(3 - 2) = 0.3432

P(x = 3) = (3 C 3) * (0.98^3) * (1 - 0.98)^(3 - 3) = 0.941192

The PMF for x is:

P(x = 0) = 0.0004

P(x = 1) = 0.0588

P(x = 2) = 0.3432

P(x = 3) = 0.941192

To calculate the CMF, we sum up the probabilities up to x:

F(x) = P(X ≤ x) = P(x = 0) + P(x = 1) + ... + P(x = x)

Using the calculated probabilities, the CMF for x is:

F(x = 0) = 0.0004

F(x = 1) = 0.0592

F(x = 2) = 0.4024

F(x = 3) = 1.0

Therefore, the probability mass function (PMF) for x is {0.0004, 0.0588, 0.3432, 0.941192}, and the cumulative mass function (CMF) for x is {0.0004, 0.0592, 0.4024, 1.0}.

Based on Amadou's measurements, the height of the skyscraper is approximately 97.2 meters.

Amadou measures the angle of elevation from his eye to the top of the skyscraper as 44 degrees. To determine the height of the skyscraper, we can use trigonometry. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side.

In this case, the opposite side represents the height of the skyscraper, and the adjacent side represents the horizontal distance from Amadou to the base of the skyscraper. We are given that the adjacent side is 164 meters and the angle of elevation is 44 degrees.

Using the tangent function, we can set up the following equation:

tan(44 degrees) = height of skyscraper / 164 meters

To solve for the height of the skyscraper, we rearrange the equation:

height of skyscraper = tan(44 degrees) * 164 meters

Using a scientific calculator or trigonometric table, we find that tan(44 degrees) is approximately 0.9659. Multiplying this value by 164 meters gives us the height of the skyscraper:

height of skyscraper ≈ 0.9659 * 164 meters ≈ 97.2 meters

To determine the probability that the average shoe size of five randomly chosen women is 9 or more, we need to calculate the z-score for this value and then find the corresponding probability using the Normal distribution.

In summary, we want to find the probability that the average shoe size of five randomly chosen women is 9 or more.

Now, let's explain the answer in more detail. The distribution of women's shoe sizes in the US follows a Normal distribution with a mean of 8 and a standard deviation of 1.5. To calculate the probability, we first need to find the z-score corresponding to a shoe size of 9 or more.

The z-score formula is given by z = (x - μ) / σ, where x is the value of interest, μ is the mean, and σ is the standard deviation. In this case, the value of interest is 9, the mean is 8, and the standard deviation is 1.5. Plugging these values into the formula, we get z = (9 - 8) / 1.5 = 0.67.

Next, we use a standard Normal distribution table or a statistical calculator to find the probability corresponding to the z-score of 0.67. The probability of obtaining a z-score of 0.67 or higher represents the probability that the average shoe size of five randomly chosen women is 9 or more.

After 10 seconds, the snail is 14 inches away from Diana. Let's assume that Diana is at the origin (0,0) and the snail moves at a constant speed. Let's consider the snail is at point (x, y) and Diana is at the origin (0,0). The snail is moving away from Diana at a constant speed. It moves 2 inches in 4 seconds.

Then the distance traveled by the snail in 1 second is

= 2/4inches

= 0.5 inches.

So, the distance the snail travels from (0,0) in x seconds is 0.5x. After 3 seconds, the snail moves

= 0.5(3)

= 1.5 inches away from Diana, and its distance from her is 9 inches.

So, we have y = 9 + 0.5x. This is the equation for the snail's distance from Diana, y, as a function of time, x.

We can see that the equation y = 9 + 0.5x provides the snail's distance from Diana. Here, y is the distance between Diana and the snail and x is the current time. We can observe that the snail moves at a constant pace of 0.5 inches per second since the coefficient of x is equal to 0.5. The constant term in the equation is 9, which stands for the separation between Diana and the snail at the initial value of x, or 0, the starting point.

Therefore, we can infer that the distance between the snail and Diana, y, as a function of time, x, is represented by the equation y = 9 + 0.5x. The distance between Diana and the snail can be calculated at any time using this equation. The distance between Diana and the snail after 10 seconds, for instance, can be calculated using this equation.

For this,

we substitute x = 10 in the equation and get

y = 9 + 0.5(10)

= 14.

Therefore, after 10 seconds, the snail is 14 inches away from Diana.

To find the amount of the payment that goes towards interest at the 12th payment, you should multiply the balance at the 12th payment by the interest rate which is 8%.

The balance of the loan after 12 payments is $4159.90.

Thus the amount of the payment that goes towards interest at the 12th payment is:

4159.90 × 0.08 = $332.79

The principal amount paid at the 12th payment is the difference between the monthly payment of $187.80 and the amount of interest paid of $332.79.

The principal amount paid at the 12th payment

= $187.80 − $332.79

= −$144.99

The negative answer means that the amount paid is the interest.

To find the balance of the loan after the 35th payment, we will subtract the monthly payment from the balance after the 34th payment.

Therefore, the balance of the loan after the 35th payment is:

380.60 − 187.80 = $192.80

To find the amount of the payment that goes towards interest at the 35th payment, you should multiply the balance at the 35th payment by the interest rate which is 8%.

The balance after the 34th payment is $380.60, so the interest payment at the 35th payment is:

380.60 × 0.08 = $30.44

The principal amount paid at the 35th payment is the difference between the monthly payment of $187.80 and the amount of interest paid of $30.44.

The principal amount paid at the 35th payment

= $187.80 − $30.44

= $157.36

Therefore, the balance of the loan after the 35th payment is:

192.80 − 157.36 = $35.44.

The balance of the loan after the 35th payment is $35.44.

1/10 of the baker's total cost for 100 pounds of chocolate sprinkles is 10x dollars.

To find 1/10 of the baker's total cost for 100 pounds of chocolate sprinkles, we need to determine the cost per pound of chocolate sprinkles.

Let's assume the cost per pound of chocolate sprinkles is 'x' dollars.

Since it is mentioned that chocolate sprinkles cost as much per pound as sugar, we can assume that the cost per pound of sugar is also 'x' dollars.

Now, let's calculate the total cost for 100 pounds of chocolate sprinkles:

Total cost = Cost per pound * Number of pounds

Total cost = x * 100

Total cost = 100x dollars

To find 1/10 of the total cost, we multiply the total cost by 1/10:

1/10 of total cost = (1/10) * (100x)

1/10 of total cost = 10x

Therefore, 1/10 of the baker's total cost for 100 pounds of chocolate sprinkles is 10x dollars.

7,875 lbs.

Old furniture weighs = 1,123 lbs.

Combined weight of furniture and truck = 8,122 lbs.

New items = 876 lbs.

First, subtract the weight of the old furniture from the combined weight:

8,122 lbs - 1,123 lbs. = 6,999 lbs.

Then, add the weight of the new items:

6,999 lbs + 876 lbs. = 7,875 lbs.

The solution to the system of equations is (x, y) = (2, 1).

Given equations are,1. 1/4x + 1/2y = 5/82. 3/4x - 1/2y = 27/8 - 3/8

Now we will solve these two equations by elimination method:

Multiplying equation 1 by 3 and equation 2 by 2,3/4x + 3/2y = 15/8  -------------- (3)

3/2x - y = 6/8 -------------- (4)

Simplifying equation 3,3/4x + 3/2y = 15/8 -------------- (5)

Multiplying equation 4 by 3,4.5x - 3y = 3 -------------- (6)

Now, we will add equation 5 and equation 6,

3/4x + 3/2y = 15/8 -------------- (5)

4.5x - 3y = 3 -------------- (6)

______________15/4x + 0y = 39/8

Therefore, x = 2.Now, substituting x=2 in equation 4,3/2(2) - y = 6/8-3y = -3/8

Therefore, y = 1.

Hence, the solution to the system of equations is (x, y) = (2, 1).

We are given 2 equations as follows:1/4x + 1/2y = 5/8 ...(i)3/4x - 1/2y = 27/8 - 3/8 ...(ii)

Multiplying equation (i) by 3 and equation (ii) by 2,3/4x + 3/2y = 15/8...(iii)3/2x - y = 6/8 ...(iv)We can write equation (iii) as follows: y = (3/2x - 6/8)/-1 = 3/2x - 6/8Now we substitute this value of y in equation (i)1/4x + 1/2(3/2x - 6/8) = 5/8Simplifying,3/4x - 3/8 = 5/8 => 3/4x = 5/8 + 3/8 => 3/4x = 1 => x = 4/3

Now we substitute this value of x in equation (iv):y = 3/2(4/3) - 6/8 = 2/1 = 2

Therefore, the solution to the system of equations is (x, y) = (4/3, 2).
