Answer:

  a.  16%

Step-by-step explanation:

The difference from the mean is ...

  (x - µ) = 4420 lb -3550 lb = 870 lb

Then the minimum Z-score of the traffic of interest is ...

  (x - µ)/σ = (870 lb)/(870 lb) = 1

__

The "empirical rule" tells you that 68% of a normal distribution is within 1 σ (Z = ±1) of the mean. If 68% is inside that range, then the remaining 32% is outside that range. The normal distribution is symmetrical about the mean, so half that quantity is below Z = -1, and the other half, 16%, is above Z=1.

About 16% of the cars have weights more than 4420 pounds.

28 miles per gallon

560/20=28

Step-by-step explanation:

Plz give me brainliest

Number of miles a car travels are 28.

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.

Number of gallons of gas = 20

A car with 20 gallons of gas can drive 560 miles

Based on the given conditions,

= \(\frac{560}{20}\)

= 28

Hence, number of miles are 28.

In the given angles, the values of R=31⁰, x=34⁰, m<S= 38⁰, m<Y = 111⁰

We know that a triangle is a polygon whose sum of angles is equal to 180 degress , with three sides and three vertices.

The given angles are

31⁰,  (x+4)⁰,  (3x+9)⁰

The sum of angles of the triangle

31+x+4+3x+9=180⁰

44+4x=180⁰

Collecting like terms

4x=136

Dividing by 4

x=34⁰

Substituting the value of x=34 in the given angles we have

R= 31⁰,             given

 (x+4)⁰   = 34+4=38⁰,  (3*34+9)⁰=111⁰

The amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

In the question, we are informed that the triangle KLM, represents a section of a park set aside for picnic tables. We are also informed that the picnic area will take up approximately 400 square yards of the park.

We are asked for the amount of fencing needed to surround the perimeter of the picnic area of the park.

We know the area of a triangle can be found using the trigonometric area formula, Area = (1/2)ab sin C.

Using this in the given triangle KLM, we get:

Area = (1/2)(KL)(KM)(sin K),

or, 400 = (1/2)(KL)(45)(sin 25°),

or, KL = (400*2)/(45*sin 25°) = 800/(45*0.42262) = 800/19.017822 = 42.0658 ≈ 42 yd.

Thus, we get KL = 42 yards.

Now, the perimeter of the picnic area = the perimeter of the triangle KLM = KL + LM + MK = 42 + 20 + 45 yards = 107 yards.

Thus, the amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

Answer: b

Step-by-step explanation:

Answer:

quite simple

Step-by-step explanation:

When multiplying a monomial by a monomial, multiply the coefficients and then multiply the variables. When multiplying variables that are the same, use the product of powers property to add the exponents. When multiplying a monomial by a binomial, multiply the factors of the monomial into each term of the binomial.

Question 1a

To calculate the book value at the end of the first year using straight-line depreciation, we need to determine the annual depreciation expense first. The straight-line method assumes that the asset depreciates by an equal amount each year over its useful life. Therefore, we can use the following formula to calculate the annual depreciation:

Annual Depreciation = (Cost - Salvage Value) / Useful Life

Substituting the given values, we get:

Annual Depreciation = ($200,000 - $20,000) / 10 years = $18,000 per year

This means that the tractor will depreciate by $18,000 each year for the next 10 years.

To determine the book value at the end of the first year, we need to subtract the depreciation expense for the year from the original cost of the tractor. Since one year has passed, the depreciation expense for the first year will be:

Depreciation Expense for Year 1 = $18,000

Therefore, the book value of the tractor at the end of the first year will be:

Book Value = Cost - Depreciation Expense for Year 1

= $200,000 - $18,000

= $182,000

So the book value of the tractor at the end of the first year, December 31, 2022, using straight-line depreciation is $182,000. so the answer is D

Question 1(b)

To determine the farmer's noncurrent liabilities, we need to use the information provided to calculate the total liabilities and then subtract the current liabilities from it. Here's the step-by-step solution:

Calculate the total current liabilities using the current ratio:

Current Ratio = Current Assets / Current Liabilities

2 = $80,000 / Current Liabilities

Current Liabilities = $80,000 / 2

Current Liabilities = $40,000

Calculate the total liabilities using the debt/equity ratio:

Debt/Equity Ratio = Total Liabilities / Owner Equity

1.0 = Total Liabilities / $100,000

Total Liabilities = $100,000 * 1.0

Total Liabilities = $100,000

Subtract the current liabilities from the total liabilities to get the noncurrent liabilities:

Noncurrent Liabilities = Total Liabilities - Current Liabilities

Noncurrent Liabilities = $100,000 - $40,000

Noncurrent Liabilities = $60,000

Therefore, the farmer's noncurrent liabilities are $60,000. so the answer is B.

Answer:

The distance is 12 miles

Step-by-step explanation:

Given

See attachment for grid

Required

The distance

From the attached:

\(B = (-8,6)\) --- Bank

\(H = (4,6)\) --- Hiroto's house

Using distance formula, we have:

\(d = \sqrt{(x_1- x_2)^2 + (y_1 - y_2)^2}\)

This gives:

\(d = \sqrt{(-8- 4)^2 + (6 - 6)^2}\)

\(d = \sqrt{(-12)^2}\)

\(d = \sqrt{144}\)

\(d = 12\)

As a result of answering the given question, we may state that As a result, the recursive formula for this geometric sequences is as follows: a1 = 2, a2 = 10, a3 = 50, and a4 = 250 a = 5 * an-1.

A sequence is an ordered list of elements in mathematics. Numbers, functions, and other mathematical objects can be used as elements. A series is frequently denoted by stating its terms in parenthesis, separated by commas. The series of natural numbers, for example, can be denoted as: (1, 2, 3, 4, 5, ...) Similarly, the series of even numbers is denoted as follows: (2, 4, 6, 8, 10, ...) Depending on whether it has a finite or infinite number of terms, a sequence might be finite or infinite.

We must first discover the common ratio, r, in order to find the explicit and recursive formulas for this geometric series.

To accomplish this, divide any phrase by its preceding term:

\(10 / 2 = 5\s50 / 10 = 5\s250 / 50 = 5\\\)

The common ratio r is 5, as we can see.

\(a = a1 * r^(n-1) (n-1)\\a = 2 * 5^(n-1) (n-1)\)

A geometric sequence's recursive formula is:

\(a = r * an-1\)

where a represents the nth phrase and an-1 represents the (n-1)th term.

The initial term a1 in this series is 2, and the common ratio r is 5. As a result, the recursive formula is:

\(a1 = 2\san = 5 * an-1\)

As a result, the recursive formula for this geometric series is as follows:

a1 = 2, a2 = 10, a3 = 50, and a4 = 250 a = 5 * an-1.

Answer:

  (a)  27 days

  (b)  70 miles

Step-by-step explanation:

Given that the track remaining to be laid is L(d) = 189 -7d, you want (a) the number of days to lay all the track, and (b) the amount remaining after 17 days.

When the amount remaining is 0, the number of days that have elapsed is ...

  0 = L(d)

  0 = 189 -7d

  7d = 189 . . . . . . add 7d

  d = 27 . . . . . . . . divide by 7

It will take the crew 27 days to lay all the track.

The track remaining after 17 days is ...

  L(17) = 189 -7(17) = 189 -119 = 70

70 miles of track remain to be laid after 17 days.
