The area of the given  isosceles triangle is 480 square units.

Isosceles triangle:

An isosceles triangle is a triangle with two sides of equal length. Let's do a little activity to understand this better. Take a square piece of paper and fold it in half. Draw a line from the folded top corner to the bottom edge (see image below). Open the sheet and you will see a triangle. Mark the triangle vertices as O, D, C. Then measure OD and OC. Repeat this activity at different scales and observe patterns. We can see that OD and OC are always the same. A triangle with two equal sides is called an isosceles triangle.

Given,

base (b) = 20 units and

height (h) = 120 units.

The formula to calculate the area is 1/2 × b × h square units.

By substituting the values, we get

⇒ Area = 1/2 × 20 × 120

            = 480 unit Squares

Therefore, the area of the given  isosceles triangle is 96 square units.

Answer:

Answer:

Beth is five years old.

Step-by-step:

Beth + Julio + Gerald + Debra = 38

B + (Beth - 2) + (2 x Beth) + (2 x Gerald) = 38

Since we know that Gerald is twice as old as Beth and Debra is twice as old as Gerald. That makes Debra four times older than Beth.

Beth + (Beth - 2) + (2 x Beth) + (4 x Beth) = 38

B +  (B -2) + (2B) + (4B) = 38

Simplfy the like terms.

8B - 2 = 38

Add 2 on both sides.

8B = 38 + 2

8B = 40

Divide both sides by 8 to isolate the variable.

To calculate the time it will take approximately 31.48 to pay off the balance on your VISA credit card, we can use the formula for the number of periods (months) required to repay a loan with a fixed monthly payment. The correct answer is 31.48 months.

The formula is:

n = -(1/30) * log(1 - ((r * P) / A))

First, let's calculate the monthly interest rate (r):

r = 0.0233333

n = -(1/30) * log(1 - ((0.0233333 * 12500) / 860))

On average, a customer spends approximately 1.16 minutes waiting time on hold before they can start speaking to a representative.

To find the average waiting time for a customer on hold before they can start speaking to a representative, we need to consider both the arrival rate of calls and the average service time of the staff members.

Given:

9 staff members taking calls.

On average, one call arrives every 5 minutes (standard deviation of 5 minutes).

Each staff member spends on average 18 minutes with each customer (with a standard deviation of 27 minutes).

To calculate the average waiting time, we need to use queuing theory, specifically the M/M/c queuing model. In this model:

"M" stands for Markovian or memoryless arrival and service times.

"c" represents the number of servers.

In our case, we have an M/M/9 queuing model since we have 9 staff members.

The average waiting time for a customer on hold is given by the following formula:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

Where:

c = number of servers (staff members) = 9

μ = average service rate (1 / average service time)

λ = average arrival rate (1 / average interarrival time)

ρ = λ / (c * μ)

First, let's calculate the average arrival rate (λ):

λ = 1 / (average interarrival time) = 1 / 5 minutes = 0.2 calls per minute

Next, calculate the average service rate (μ):

μ = 1 / (average service time) = 1 / 18 minutes = 0.0556 customers per minute

Now, calculate ρ:

ρ = λ / (c * μ) = 0.2 / (9 * 0.0556) ≈ 0.407

Finally, calculate the waiting time:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

= (1 / (9 * (0.0556 - 0.2))) * (0.407 / (1 - 0.407))

≈ 1.16 minutes

Therefore, on average, a customer spends approximately 1.16 minutes waiting on hold before they can start speaking to a representative.

a) The change-of-coordinates matrix from basis A to basis B is C = [4 -1 0; -1 1 1; 0 1 -2].

b)  The vector [x]g for x = 3a + 4a2 + az is [11; -2; -6] in the basis B.

a. To find the change-of-coordinates matrix from basis A to basis B, we need to express the vectors in A as linear combinations of the vectors in B.

From the given information, we have

a = 4b – b2, a = -b1 + b2 + b3, and az = b2 – 2b3.

We can rewrite these equations as linear combinations:

a = 4b – b2 + 0b3, a = -b1 + b2 + b3, and az = 0b1 + b2 – 2b3.

Using these expressions, we can construct a matrix where the columns correspond to the vectors in A expressed in terms of the vectors in B. The change-of-coordinates matrix C is given by:

C = [4 -1 0; -1 1 1; 0 1 -2].

b. To find [x]g for x = 3a + 4a2 + az, we can use the change-of-coordinates matrix C.

First, we express the vector x in terms of the basis A:

x = 3(aj) + 4(az) + (az).

Then, we can rewrite x in terms of the basis B using the change-of-coordinates matrix:

[x]g = C[x]A.

Calculating the matrix-vector multiplication, we have:

[x]g = C * [3; 4; 1] = [11; -2; -6].

Therefore, the vector [x]g in the basis B is [11; -2; -6].

The probability distribution's mean and standard deviation, Y, will be 0.4899 and 0.699, respectively, based on the information provided.

By dividing the sum of the supplied numbers by the entire number of numbers, the mean—the average of the given numbers—is determined.

The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data collection more accurately than the average does. It reflects the midway of the data since it is the point above and below which half (50%) of the observed data falls.

Mean= (Sum of All Observations/Total number of Observations).

How is a probability distribution made?

It should be noted that the probability distribution for y will be as follows given the probability distribution:

Y                         0           1         . 2

Probabilities      0.63     0.25,  0.12

The median value of Y is:

Mean = (0 × 0.63) + (1 × 0.25) + (2 × 0.12)

Mean = 0 + 0.25 + 0.25

Mean = 0.49

The variance will be 0.4899. Therefore, the standard deviation will be:

standard deviation = ✓0.4899

=> Standard Deviation = 0.699

So, The probability distribution's mean and standard deviation, Y, will be 0.4899 and 0.699, respectively

According to the rectangle plot, the total length of fence that Farmer Ted will use can be expressed in terms of x as 2x + 432/x.

Now, the problem asks us to find the total length of fence that Farmer Ted will use to enclose the rectangle and divide it into two equal parts using another fence parallel to one of the sides. To solve this problem, we need to first visualize the rectangle and understand what's happening.

Next, we need to enclose the rectangle with a fence. This means we need to find the perimeter of the rectangle, which is the total length of all its sides. The perimeter of a rectangle can be found by adding up the lengths of all its sides:

Perimeter = 2x + 2y

Now we have two smaller rectangles with dimensions x by y/2. The total area of both rectangles is still 216 square meters, so we can set up an equation to solve for y:

(x)(y/2) + (x)(y/2) = 216

Simplifying this equation, we get:

xy = 216

We can now use this equation to solve for y in terms of x:

y = 216/x

We can substitute this value for y in the equation for the perimeter of the original rectangle:

Perimeter = 2x + 2y

Perimeter = 2x + 2(216/x)

Simplifying this equation, we get:

Perimeter = 2x + 432/x

The normally distributed process has specifications of LSL = 75 and USL = 85 has a Cp of 2.22 , this process is capable and 0.08 defective parts can be expected per day.

To obtain the estimate of Cp, we first need to calculate the process capability index (Cpk) using the formula:

Cpk = min[(USL - mean) / (3 * standard deviation), (mean - LSL) / (3 * standard deviation)]

In this case, the sample mean is 80 and the sample standard deviation is 1.5, so:

Cpk = min[(85 - 80) / (3 * 1.5), (80 - 75) / (3 * 1.5)]
   = min[1.11, 1.11]
   = 1.11

To obtain Cp, we simply multiply Cpk by 2, since Cp = 2 * Cpk when the process is centered:

Cp = 2 * Cpk
  = 2 * 1.11
  = 2.22

Since Cp is greater than 1.0, this process is capable.

To calculate the expected number of defective parts per day, we need to know the proportion of parts that are defective.

Assuming that the process is centered, the proportion of parts that are defective can be estimated using the area under the normal distribution curve beyond the specification limits.

Since the process is normally distributed with mean 80 and standard deviation 1.5, we can use a standard normal distribution table to find the area beyond the limits:

Area beyond USL = P(Z > (USL - mean) / standard deviation) = P(Z > (85 - 80) / 1.5) = P(Z > 3.33) = 0.0004

Area beyond LSL = P(Z < (LSL - mean) / standard deviation) = P(Z < (75 - 80) / 1.5) = P(Z < -3.33) = 0.0004

So the proportion of parts that are defective is:

Proportion defective = 0.0004 + 0.0004 = 0.0008

To find the expected number of defective parts per day, we multiply this proportion by the number of parts produced per day:

Expected number of defective parts per day = 0.0008 * 100 = 0.08

So we would expect to see approximately 0.08 defective parts per day.

Step-by-step explanation:

We need to use FOIL

Multiply the FIRST terms of each set together

Then the OUTSIDE terms

Then the INSIDE terms

and then the LAST terms

Thus:

\(2*2x = 4x\)

\(2*3 = 6\)

\(-4*3 = -12\)

\(-4*2x = -8x\)
