Answer 1

Answer:

Below

Step-by-step explanation:

Area of a triangle = 1/2 base * height

this triangle has base = 4 ( 3 in) = 12 in and height = 3 (3 in) = 9 in

area = 1/2 * 12 * 9 = 54 in^2

54 in^2 * $ 2.75 /in^2 = $ 148.50

If the window is scaled down by .5 then the dimensions would be

base = 6 in height = 4.5 in

area = 1/2 * 6 * 4.5 = 13.5 in^2

cost would be 13.5 in^2 * $ 2.75/in^2 =~ $37.13

question jordan wondered if the bean burritos at restaurant a tend to be heavier than bean burritos at restaurant b. to investigate, she visited each restaurant at 10 randomly selected times, ordered a bean burrito, and weighed the burrito. the 95% confidence interval for the difference (a - b) in the mean weight of the burrito is 0.06 ounce 0.20 ounce. based on the confidence interval, which conclusion is most appropriate?

Answers

The conclusion of question as discuss below.

Define the term mean?

The mean is a measure of central tendency that represents the average value of a set of numbers. It is calculated by adding up all the values in the set and then dividing by the total number of values.

Based on the given information, we can say that there is a 95% chance that the true difference (a - b) in the mean weight of the bean burritos between Restaurant A and Restaurant B falls within the interval 0.06 ounce to 0.20 ounce.

Since the confidence interval does not include zero, we can conclude that there is a statistically significant difference between the mean weights of the bean burritos at the two restaurants. Specifically, we can say that the mean weight of the bean burritos at Restaurant A is likely to be heavier than the mean weight of the bean burritos at Restaurant B.

However, it's important to note that we cannot determine the magnitude of the difference or the direction of causation (i.e., whether Restaurant A intentionally makes their burritos heavier or whether they use different ingredients that naturally result in heavier burritos).

We can infer that there is a statistically significant difference among the mean weights of the bean burritos at the two eateries because the confidence interval does not include zero.

Define the term mean?

The mean, which reflects the average value of a group of numbers, is a metric of central tendency. It can be calculated by adding up all of the values in the collection, dividing by the total number of values, and then taking the remainder away.

Based on the information provided, we can state that there is a 95% chance that the actual difference (a - b) between Restaurant A and

Restaurant B's mean weight of the bean burritos will lie between 0.06 ounce and 0.20 ounce.

We can infer that there is a statistically significant variance among the mean weights of the bean burritos at the two eateries because the confidence interval does not include zero. We can specifically state that the bean burritos' average weight at Restaurant A is probably heavier than the average bean burrito's weight at Restaurant B.

It's crucial to remember that we cannot establish the size of the difference or the causal relationship. (i.e., whether Restaurant A intentionally makes their burritos heavier or whether they use different ingredients that naturally result in heavier burritos).

Which equation is true when x = 3?

Group of answer choices

8x = 28

x - 19 = 16

28 + x = 25

x/3 = 1

Answers

The equation that is true when x is equal to 3 is (x/3) = 1. By substituting the given x value and simplifying the equation we can solve.

What is division?

Division is a mathematical operation that is used to split a quantity or value into equal parts or groups. It is one of the four basic arithmetic operations, along with addition, subtraction, and multiplication.

According to question:

The equation that is true when x = 3 is:

x/3 = 1

Substituting x = 3, we get:

3/3 = 1

Which is true, since 3 divided by 3 is equal to 1.

The other equations:

8x = 28: If we substitute x = 3, we get 8(3) = 24, which is not equal to 28, so this equation is not true when x = 3.x - 19 = 16: If we substitute x = 3, we get 3 - 19 = -16, which is not equal to 16, so this equation is not true when x = 3.28 + x = 25: If we substitute x = 3, we get 28 + 3 = 31, which is not equal to 25, so this equation is not true when x = 3.

Suppose that the Local sales tax rate is 4% and you purchase a car for 24,500. A. How much Tax is paid?
B. What is the car’s total cost?

Answers

The purchase cost of a car 24,500 with local sales tax rate 4% has following answer,

Total tax paid = $980

Total cost of a car including tax = $25.480.

Purchasing cost of a car = $24,500

Local sales tax rate on a car = 4%

Tax paid on the car purchase = (Purchase price) × (tax rate)

Substitute the value we get,

⇒ Tax amount = 4% of 24,500

⇒ Tax amount = 0.04 x 24,500

⇒ Tax amount = $980

Total cost of a car including tax = ( Tax amount ) + (Purchase price )

Substitute the value we have,

⇒ Total cost of a car = Purchase price + Tax amount

⇒ Total cost of a car = 24,500 + 980

⇒ Total cost of a car = $25,480

Therefore, the tax paid on the car purchase and the car's total cost including tax is equal to $980 and $25,480 respectively.

The same video is uploaded to a different website. There are also 100 views in day one ,but 400 views on day 2and 1,600 views on day 3. Explain how the explicit and rescursive formula change

Answers

The explicit formula is given by the equation a(n) = 50n² + 25n + 25 and the recursive formula is given by a(n) = a(n-1) + 200, with a(1) = 100.

What is the finite differences method?

A approach for identifying patterns in numerical sequences is the method of finite differences. It entails first identifying the differences between each word in the sequence, then repeating the procedure with the sequence of differences that results. If a pattern forms where the gaps between the gaps are always the same, the initial sequence exhibits a polynomial pattern. Both the recursive formula, which enables us to compute any term by utilising the previous term in the series, and the explicit formula for the sequence, which allows us to calculate any term in the sequence directly, can be found using the procedure.

Given the views on different days we have:

First finite difference: 300-100 = 200

Second finite difference: 1200-300 = 900

We observe that second finite difference is constant and hence follows a quadratic pattern.

Using the explicit formula we have:

a(n) = 50n² + 25n + 25

where, a(n) is the views on day n.

Using recursive formula:

a(n) = a(n-1) + 200, with a(1) = 100

Hence, the explicit formula is given by the equation a(n) = 50n² + 25n + 25 and the recursive formula is given by a(n) = a(n-1) + 200, with a(1) = 100.
