The area of the sidewalk is 388 square feet.

To find the area of the sidewalk you can find the area of each individual shape and add them together.

Area of the first triangle T = (1/2) x 6 ft x 11 ft = 33 sq. ft.

Area of the second triangle = (1/2) x 6 ft x 18 ft = 54 sq. ft.

Area of the rectangle = 6 ft x 30 ft = 180 sq. ft.

Area of the square = 11 ft x 11 ft = 121 sq. ft.

Therefore, the total area of the sidewalk is:

33 sq. ft. + 54 sq. ft. + 180 sq. ft. + 121 sq. ft. = 388 sq. ft.

So, the area of the sidewalk is 388 square feet.

Answer:

The total DOWNWARD vertical distance the ball has traveled after it hits the surface the 5th time is 23.056 feet.

Step-by-step explanation:

Geometric sequence:

The nth term is a product of the previous(nth-1) term and the common ratio. That is:

\(a_n = qa_{n-1}\)

In which q is the common difference.

Sum of the first n terms of geometric sequence:

The sum of the first n terms of a geometric sequence is given by:

\(S_n = \frac{a_1(1-q^n)}{1-q}\)

A rubber ball is dropped from a height of 10 feet onto a hard surface.

This means that \(a_1 = 10\)

The ball is 6 feet in the air and continues to follow a sequence of bounces

This means that \(q = \frac{6}{10} = 0.6\)

What is the total DOWNWARD vertical distance the ball has traveled after it hits the surface the 5th time?

This is \(S_5\). So

\(S_5 = \frac{10(1-0.6^5)}{1-0.6} = 23.056\)

The total DOWNWARD vertical distance the ball has traveled after it hits the surface the 5th time is 23.056 feet.

Step-by-step explanation:

There are 4 groups

1. Alto

2. Bass

3. Tenor

4. Soprano

The question says "what is the probability that this member comes from the alto section"

Since there are 4 groups, I did 4/8 (since there are 8 people in Alto) and I got 0.5.

Hope I got it right and it helped you

*Note* I most likely got it right I just doubt myself too much lol

But just in case, I hope I got it right.

Answer:

there are 4 parts in that choir and the alto members are 8 in number so we say those in alto divided by the number of parts, we get→ 4÷8 =0.5, that's the ans.

the left side of this equation equal the right side through the process of completing the square that establishes the equality between the left side and the right side of the Gaussian integral equation.

using  completing the square method:

Starting with the left side of the equation:

∫\(e^(^-^x^2)\) dx

\(e^(^-^x^2) = (e^(^-x^2/2))^2\)

∫\((e^(^-^x^2/2))^2 dx\)

let  u = √(x²/2) =  x = √(2u²).

dx = √2u du.

∫ \((e^(^x^2/2))^2 dx\)

= ∫ \((e^(^-2u^2)\)) (√2u du)

The integral of \(e^(-2u^2)\)= √(π/2).

∫ \((e^(-x^2/2))^2\) dx

= ∫  (√2u du) \((e^(-2u^2))\\\)

= √(π/2) ∫ (√2u du)

We substitute back  u = √(x²/2), we obtain:

∫ \((e^(-x^2/2))^2\)dx

= √(π/2) (√(x²/2))²

= √(π/2) (x²/2)

= (√π/2) x²

A comparison  with the right side of the equation  shows that they are are equal.

Step-by-step explanation:

The set (A U B) n (A U C) is {2, 5, 7, 10}. A.

To find the set (A U B) n (A U C), we first need to calculate the union of sets A and B, and then calculate the union of that result with set C. Finally, we find the intersection of these two sets.

Set A U B:

The union of sets A and B, denoted as A U B, is the combination of all elements from both sets without any repetitions.

A contains the elements 2, 5, 7, and 10, while B contains the elements 1, 2, and 3.

A U B consists of the elements {1, 2, 3, 5, 7, 10}.

Set (A U B) U C:

Next, we calculate the union of the set (A U B) with set C, denoted as (A U B) U C. A U B contains the elements {1, 2, 3, 5, 7, 10} and C contains the elements {1, 2, 3, 4, 5}.

Taking the union of these two sets results in {1, 2, 3, 4, 5, 7, 10}.

Finding the intersection:

Finally, we find the intersection of (A U B) U C with A U C. A U C consists of the elements {2, 5, 7, 10}.

The intersection of these two sets is the combination of common elements.

The common elements are {2, 5, 7, 10}.

Answer:

99% confidence interval is wider as compared to the 80% confidence interval.

Step-by-step explanation:

We are given that a magazine provided results from a poll of 500 adults who were asked to identify their favorite pie.

Among the 500 respondents, 14​% chose chocolate​ pie, and the margin of error was given as plus or minus ±3 percentage points. 

The pivotal quantity for the confidence interval for the population proportion is given by;

                            P.Q.  =  \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\)  ~ N(0,1)

where, \(\hat p\) = sample proportion of adults who chose chocolate​ pie = 14%

            n = sample of adults = 500

            p = true proportion

Now, the 99% confidence interval for p =  \(\hat p \pm Z_(_\frac{\alpha}{2}_) \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)

Here, \(\alpha\) = 1% so  \((\frac{\alpha}{2})\) = 0.5%. So, the critical value of z at 0.5% significance level is 2.5758.

Also, Margin of error = \(Z_(_\frac{\alpha}{2}_) \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)  = 0.03 for 99% interval.

So, 99% confidence interval for p  =  \(0.14 \pm2.5758 \times \sqrt{\frac{0.14(1-0.14)}{500} }\)

                                                        = [0.14 - 0.03 , 0.14 + 0.03]

                                                        = [0.11 , 0.17]

Similarly, 80% confidence interval for p  =  \(0.14 \pm 1.2816 \times \sqrt{\frac{0.14(1-0.14)}{500} }\)

Here, \(\alpha\) = 20% so  \((\frac{\alpha}{2})\) = 10%. So, the critical value of z at 10% significance level is 1.2816.

Also, Margin of error = \(Z_(_\frac{\alpha}{2}_) \times \sqrt{\frac{\hat p(1-\hat p)}{n} }\)  = 0.02 for 80% interval.

So, 80% confidence interval for p  =  [0.14 - 0.02 , 0.14 + 0.02]

                                                           =  [0.12 , 0.16]

Now, as we can clearly see that 99% confidence interval is wider as compared to 80% confidence interval. This is because more the confidence level wider is the confidence interval and we are more confident about true population parameter.

Answer: To calculate the monthly payment, we need to use the formula for the equal monthly installment for a loan with constant payments and interest:

P = (r * PV) / (1 - (1 + r)^-n)

where:

P = monthly payment

r = monthly interest rate

PV = present value (the initial loan amount)

n = total number of payments

In this case, PV = $3500, n = 60, and r = 1.75% per month.

First, we can calculate the monthly interest rate by dividing the annual rate by 12:

r = 1.75% / 100% / 12 = 0.0175/12

Plugging in the values, we get:

P = (0.0175/12 * $3500) / (1 - (1 + 0.0175/12)^-60)

P = $69.92 (rounded to two decimal places)

So the monthly payment is $69.92.

To calculate the total interest paid, we can subtract the initial loan amount from the total of all payments:

Total interest = (P * n) - PV

Total interest = ($69.92 * 60) - $3500

Total interest = $195.20

So the total interest paid is $195.20.

Step-by-step explanation:

Answer: The total interest paid is $1186.

Step-by-step explanation: The first step is to calculate the monthly interest rate:

1.75% per month can be written as 0.0175 in decimal form.

Next, we can use the formula for the monthly payment of a loan:

P = r(PV) / [1 - (1+r)^(-n)]

Where:

P = monthly payment

r = monthly interest rate

PV = present value of the loan

n = total number of payments

Plugging in the given values, we get:

P = 0.0175(3500) / [1 - (1+0.0175)^(-60)]

= 78.10

Therefore, your monthly payments are $78.10.

To calculate the total interest paid, we can multiply the monthly payment by the number of payments and subtract the original loan amount:

Total interest = (60 x 78.10) - 3500

= 4686 - 3500

= $1186

Therefore, the total interest paid is $1186.

The ratio of cucumber plants to the total number of plants is 5:17.

We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part-to-part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.

Given the number of tomato plants = 12

number of cucumber plants = 5

total number of plants = 12 + 5 = 17

and the ratio of the number of cucumber plants to the total number of plants

= (number of cucumber plants)/(total number of plants)

= 5/17

the symbol of the ratio is ":"

= 5:17

Answer:

L = 10, W = 6

Step-by-step explanation:

(x-2)(x+2) = 60

\(x^{2}\) - \(2^{2}\) = 60

\(x^{2}\) = 60 + 4 = 64

x = \(\sqrt{64}\) = 8 or -8

-8 rejected

thus length is 8 + 2 = 10, width is 8-2=6

The length is 10 units and width is 6 units.

Length = x+2

Width = x-2

Area = 60

Area = Length × Width

Therefore, (x+2)(x-2) = 60

x²-2x+2x - 4 = 60

Collect like terms

x² = 60+4.

x² = 64.

Therefore, in order to get the value of x, we'll find the square root of 64

x² = 64.

x = ✓64

x = 8

Length =  = x+2 = 8+2 = 10

Width = x-2 = 8-2 = 6

Answer: Quadrant 3 and Quadrant 1

Step-by-step explanation:

Answer:

wheres the diagram???

Step-by-step explanation:

The length of side x is approximately 24.87, rounded to the nearest hundredth.

how can we find side of the triangle?

To find the length of side x, we can use the sine function, which relates the opposite side to an angle to the hypotenuse:

sin(11°) = opposite side/hypotenuse

Rearranging this equation, we get:

opposite side = sin(11°) * hypotenuse

We know that the hypotenuse has a length of 130, so we can substitute that in:

opposite = sin(11°) * 130

Using a calculator, we can evaluate sin(11°) to be approximately 0.1919, so we can substitute that in as well:

opposite = 0.1919 * 130

Simplifying this expression, we get:

opposite ≈ 24.87

Therefore, the length of side x is approximately 24.87, rounded to the nearest hundredth.
