The maximum number of hikers who could have walked between 6 miles and 17 miles is 19.

We need to find the maximum number of hikers who could have walked between 6 miles and 17 miles.

When the derivative equals 0, rearrange the function using elementary algebraic principles to find the value for x. The x-coordinate of the function's vertex, which is where the maximum or lowest will occur, is provided in this answer. the solution back into the original function to determine the minimum or maximum.

From the table, we can see

Between intervals 5≤x<10 there are 2 hikers

Between intervals 10≤x<15 there are 9 hikers

Between intervals 15≤x<20 there are 8 hikers

So, total number of hikers = 2+9+8

= 19

Hence, the maximum number of hikers who could have walked between 6 miles and 17 miles is 19.

The equation of given graph is y = |x - 3| + 5.

The graph of a absolute or modulus function is a V- shape graph. The function of absolute is f(x) = |x|. The general form of absolute function is f(x)=a |x - h| + k. Where (h,k) is the vertex of graph.

Here, we can see that graph is in the form of V shape, so the function will be absolute function. Now, we have to find the vertex of graph.

As seen from the graph the minimum point on the graph is located at the point (3, 5) and the value of a should be 1.

So, by putting the value of vertex in general equation we get the equation of the graph,

y = |x - 3| + 5

Therefore, the equation of given graph is y = |x - 3| + 5.

Answer:

$3.70

Step-by-step explanation:

12 dimes, and dimes are ten cents each. So we will multiply 10*12=120. Which is $1.20.

10 quarters, and quarters are twenty-five cents each. So we will multiply 10*25=250. Which is $2.50

Now we take our two totals and add them together. 1.20+2.50=3.70.

So we have $3.70.

If EOF = 26 and FOG= 38, then the measure of BOG would be 64 degrees.

What is a measure of angle?

An angle is measured in degrees, thus the term "degree measure." Because one complete revolution equals 360 degrees, it is divided into 360 parts. Each stage of the revolution represents a degree.

The given data:

A measure of EOF = 26 and a measure of FOG = 38.

Then we can say that OF is an angle bisector of angle EOG.

Then the measure of BOG = EOF + FOG

                                            = 26 + 38

                                            =  64 degrees.

Hence, If EOF = 26 and FOG= 38, then the measure of BOG would be 64 degrees.

The accounting profit is $10,800 and economic profit is - $14,200.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

The saving of Sarah = $50,000

The interest on $25,000 Sarah withdrew at the rate of 4% = $1000

The interest on $30,000  Sarah borrowed at the rate of 4% = %1200

The amount paid for ingredients = $27,000

Total investment = 27,000+30,000+ 1000+1200 = $59,200

Revenue of Sarah = $70,000

Accounting profit of Sarah = $70,000 - $59,200 = $10,800

Economic profit of Sarah = $70,000 - ($59,200+$25,000)

                                          = - $14,200

Answer:

[tex]a_{n}[/tex] = n - 5

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

- 3 - (- 4) = - 2 - (- 3) = - 1 - (- 2) = 1

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = - 4 and d = 1 , then

[tex]a_{n}[/tex] = - 4 + 1 (n - 1) = - 4 + n - 1 = n - 5

The greater principal is there for Account A as $400.

Simple interest can be defined as a type of interest where the rate is applied on the same principal.

Given that,

The interest for Account A is $15.75 and Account B is  $28.

The total time for interest is 21 months.

Rate of interest for Account A is  3% and Account B is 4%.

Now, the time period can be written in years as,

21 months = 21 / 12 years

                  = 7 / 4

Suppose the principal for Account A and Account B is P₁ and P₂ respectively.

The formula for simple interest is given as,

(P × r × t) / 100

Substitute the respective values for both the accounts to get,

For Account A,

15.75 = (P × 3 × 7 / 4) / 100

⇒ P = (1575 × 4) / (3 × 7)

⇒ P = 300

For Account B,

28 = (P × 4 × 7 / 4) / 100

⇒ P = 2800 / 7

⇒ P = 400

Hence, Account B had greater principal.

The system of equations has its solutions to be (1, -1) and (7, -1)

The system of equations is given as

(x−4)² + (y+1)² = 9

(x−4)²/9 + (y+1)²/81 = 1

Make (y + 1)² the subject in the equation (x−4)² + (y+1)² = 9

So, we have

(y+1)² = 9 - (x−4)²

Substitute (y+1)² = 9 - (x−4)² in (x−4)²/9 + (y+1)²/81 = 1

This gives

(x−4)²/9 + [9 - (x−4)²]/81 = 1

Split

(x−4)²/9 + 9/81 - (x−4)²/81 = 1

Collect the like terms

(x−4)²/9 - (x−4)²/81 = 1 - 9/81

Evaluate the like terms

[9(x−4)² - (x−4)²]/81 = 72/81

So, we have

9(x−4)² - (x−4)² = 72

Evaluate the difference

8(x−4)² = 72

Divide by 8

(x−4)² = 9

Take the square roots

x - 4 = ±3

So, we have

x = 4 ± 3

Evaluate

x = 1 or 7

Substitute x = 1 or 7 in (y+1)² = 9 - (x−4)²

(y + 1)² = 9 - (1−4)² or (y + 1)² = 9 - (7−4)²

This gives

(y + 1)² = 0 or (y + 1)² = 0

This gives

y + 1 = 0

Evaluate

y = -1

Hence, the solution is (1, -1) and (7, -1)

(a) -0.255 is the probability that a randomly selected credit card holder has a credit card balance less than $2500. (b) You randomly select 25 credit card holders. 0.0228 is the probability that their mean credit card balance is less than $2500.

Let us pull out the critical elements

Population: Normally distributed with mean of 2870

population standard deviation = 900 standard deviation of the sample mean (standard error) is 900 / √25. or 180

As population sigma is known, we do not have apply any corrections

P(xbar < $2500) = ?    

Since μ and σ are known (population mean and standard deviation) we can use a simple Z test.

Ztest = (2500-2870 )/ 180  or -370/180 = -2.055

As this is very close to -2 one can use the rule of thumb for probability within ± 2 sigma  being 95.44% to get a close estimate.   If the area between -2 and 2 sigma = .9544 then the area outside = .0456.  Half of this (the amount under the curve LESS THAN -2) would be .0228

The probability that their mean length is greater than 20.1 inches is 0.32.

Standard deviation:

The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

The given value are:

Mean = 18.8 inches

Standard deviation = 6.2 inches

We have to find the probability that their mean length is greater than 20.1 inches.

Variance of sample mean = 6.2 / 48

                                           = 0.13

S.D of sample mean=   [tex]\sqrt{0.13}[/tex]

                                 = 0.36

Z score for the length of 20.1 is ( 20.1 - 18.8) / 0.36 = 0.468

The p-value for 0.468 in the standard normal table is 0.32.

The measures are as follows:

Hence:

7x - 3 = 4x + 8
