Answer: There are 45 miles that she have to travel to get to the next down.

Step-by-step explanation:

Since we have given that

1 inch = 15 miles

If there are given 3 inches.

We need to find the number of miles she have to travel to get to travel to get to the next town.

So, it becomes,

[tex]\dfrac{1}{15}=\dfrac{3}{x}\\\\x=15\times 3\\\\x=45\ miles[/tex]

Hence, there are 45 miles that she have to travel to get to the next down.

Answer:

The answer to your question is Positive

Step-by-step explanation:

Function

                  g(x) = x⁴ - 8x³ + x² + 42x

To know if the function is positive or negative in the interval (0, 3), look for two numbers between this interval and evaluate the function.

The numbers I chose were 1 and 2

-  g(1) = (1)⁴ - 8(1)³ + (1)² + 42(1)

         = 1 - 8 - 1 + 42

        = + 36    positive

-  g(2) = (2)⁴ - 8(2)³ + (2)² + 42(2)

          = 16 - 64 + 4 + 84

          = + 40

Conclusion

The function is positive in the interval (0, 3)

In a state where the license plates have two letters followed by four numerals, the probability of getting a license plate that has a repeated letter or digit is approximately 51.5%.

To solve this question, we need to understand the fundamental counting principle and the concept of probability. First, let's explore the total number of possibilities for a license plate of this format. The choice for each spot on the license plate is independent of each other. Therefore, there are 26 possibilities (26 letters in the English alphabet) for each of the first two spots, and 10 possibilities for each of the next four spots (0-9 digits). The total number of possibilities is thus 26 * 26 * 10 * 10 * 10 * 10, or 67,600,000 combinations.

Next, we will calculate all the combinations in which no letters or digits are repeated. There are 26 options for the first letter, 25 remaining options for the second letter, 10 options for the first digit, and then 9, 8, and 7 options for the next three positions, giving us 26 * 25 * 10 * 9 * 8 * 7 = 327,600,000 combinations.

To get the probability of a repeated letter or digit, subtract the non-repeating combinations from the total combinations, divide by the total, and then multiply by 100 to get a percentage. So the probability is (676,000,000 - 327,600,000) / 676,000,000 * 100, which gives approximately 51.5%

Answer:

u => 4,028

Step-by-step explanation:

To find the answer, we have the following formula:

u => m - t (alpha, n-1) * [sd / (n) ^ (1/2)]

where m is the mean.

where sd is the standard deviation.

where n is the sample size.

t is a parameter that depends on the confidence interval and the sample size.

alpha = 1 - ci

ci = 90% = 0.9

Therefore, alpha = 1 - 0.9 = 0.1.

n - 1 = 25 - 1 = 24

So it would come being t (0.1, 24), if we look in the table, which I will attach the value of t is equal to 1.318.

We know the rest of the values, m = 4.05; sd = 0.08; n = 25

u => 4.05 - 1,318 * [0.08 / (25) ^ (1/2)]

u => 4.028

Which means that the interval with a 90% confidence of the wall thickness measurement is:

This calculation shows that Mary Ward's lease term is 36 months.

The question is asking us to find out for how many months Mary Ward's car lease lasts. To do so, we need to calculate the total monthly payments and then subtract the initial $1600 fee to find the total cost of the monthly payments alone. Then, we divide this amount by the monthly lease payment to determine the total number of months for the lease duration.

First, we deduct the initial fee from the total lease cost:

Total lease cost - Initial fee = Total of monthly payments

$26,800 - $1,600 = $25,200

Next, we divide this result by the monthly lease payment to find out the number of months:

$25,200 / $700 = 36 months

Therefore, the lease agreement lasts for 36 months, which is typically the term for most vehicle leases.

Answer:

9 boxes of chopsticks.

Step-by-step explanation:

The first thing is to calculate the number of chopsticks spent in a day, the problem tells us that they are 15 ^ 2 = 15 * 15 = 225 chopsticks daily.

To calculate the number of chopsticks in 30 days, it is to calculate the previous amount by 30:

225 * 30 = 6750 chopsticks spent in one month.

To know how many boxes you should order is to divide the total number of chopsticks in a month and the number of chopsticks that a box brings that are 750:

6750/750 = 9 boxes of chopsticks.

Therefore you should order exactly 9 boxes of chopsticks for the restaurant's need.

Answer:

Step-by-step explanation:

According to the flaring, the triangle expressed in the figure is formed.

Now we have a vector A and vector B, whose components are Ax, Ay and Bx and By respectively.

To calculate these components you must use the following formulas:

Ax = A * cos [angle a] = 32 * cos 37 ° = 25.6

Ay = A * sin [angle a] = 32 * sin 37 ° = 19.3

Bx = B * cos [angle a] = 21 * cos 23 ° = 19.3

By = B * sin [angle b] = 21 * sin 23 ° = - 8.2

In the figure it can be seen that vector B is the result of vector A and vector C

Thus:

B = A + C

reorganizing is:

C = B - A

Now to calculate Cx and Cy, we will do it with the previously calculated components:

Cx = Bx - Ax = 19.3 - 25.6 = -6.3

Cy = By - Ay = -8.2 - 19.3 = -27.5

Now to calculate the value of vector C, we apply the following formula:

C ^ 2 = Cx ^ 2 + Cy ^ 2

Rearranging:

C = (Cx ^ 2 + Cy ^ 2) ^ (1/2)

C = [(-6.3 ^ 2) + (27.5 ^ 2)] ^ (1/2) = 28.2

Then the distance would be 28.2 meters.

Answer: the solutions of the equation are

x = - 1

x = 8

x = 9

Step-by-step explanation:

The given cubic equation is expressed as

x³ - 16x² + 55x + 72 = 0

The first step is to test for any value of x that satisfies the equation when

x³ - 16x² + 55x + 72 = 0

Assuming x = - 1, then

- 1³ - 16(-1)³ + 55(-1) + 72 = 0

- 1 - 16 - 55 + 72 = 0

0 = 0

It means that x + 1 is a factor.

To determine the other factors, we would apply the long division method. The steps are shown in the attached photo. Looking at the photo, we would factorize the quadratic equation which is expressed as

x² - 17x + 72 = 0

x² - 9x - 8x + 72 = 0

x(x - 9) - 8(x - 9) = 0

(x - 9)(x - 8) = 0

Answer:

Step-by-step explanation:

9/sin(34) = 6/sinC

sinC = 0.372795269

C = 21.9, 158.1

Since 158.1 + 34 = 192.1 > 180

Only one triangle can be formed with angle 21.9° at C

Sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.

To determine the number of distinct triangles that can be drawn with the given measurements using the Law of Sines, we need to consider the Ambiguous Case (also known as the SSA case or the "side-side-angle" case).

The Law of Sines states:

sin(A) / a = sin(B) / b = sin(C) / c

Given:

m∠A = 34°

a = 9

c = 6

We want to find ∠B and side b.

First, find ∠B using the Law of Sines:

sin(B) / b = sin(A) / a

sin(B) / b = sin(34°) / 9

Now, find sin(34°):

sin(34°) ≈ 0.5592

Now, solve for sin(B) by multiplying both sides by b:

sin(B) = (0.5592 * b)

Next, find ∠C:

Since the sum of angles in a triangle is 180°:

∠C = 180° - ∠A - ∠B

∠C = 180° - 34° - ∠B

Determine the value of side b:

Using the Law of Sines again, we have:

sin(C) / b = sin(A) / a

sin(C) / b = sin(34°) / 9

Find sin(C):

sin(C) = sin(180° - 34° - ∠B)

We can now use the fact that sin(C) = sin(180° - angle) to find sin(C):

sin(C) = sin(180° - 34° - ∠B) = sin(146° + ∠B)

Now, solve for b by multiplying both sides by b:

sin(146° + ∠B) = (sin(34°) / 9) * b

Since sin(146° + ∠B) cannot be greater than 1 (the maximum value for sine), the number of distinct triangles will depend on the possible values of b.

In this case, we have sin(146° + ∠B) = (sin(34°) / 9) * b, and since sin(34°) ≈ 0.5592, the maximum value for (sin(34°) / 9) * b is approximately 0.5592 * 6 ≈ 3.3552.

Since sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.

P [  1689  ≤   X  ≤  2267 ]  = 54,88 %

Step-by-step explanation:

Normal Distribution

Mean        μ₀  =  1730

Standard Deviation      σ  = 257

We need to calculate  z scores for the values   1689     and      2267

We apply formula for z scores

z =  ( X -  μ₀ ) /σ

X = 1689     then

z = (1689 - 1730)/ 257      ⇒ z = - 41 / 257

z  = -  0.1595

And from z table we get  for  z =  - 0,1595

We have to interpolate

        - 0,15          0,4364

        - 0,16          0,4325

Δ  =   0.01           0.0039

0,1595  -  0,15  =  0.0095

By rule of three

0,01                  0,0039

0,0095                 x ??      x  =  0.0037

And    0,4364  -  0.0037  = 0,4327

Then    P [ X ≤ 1689 ]  =  0.4327     or    P [ X ≤ 1689 ]  = 43,27 %

And for the upper limit  2267  z  score will be

z  =  ( X - 1730 ) / 257       ⇒  z =  537 / 257

z  =  2.0894

Now from z table   we find  for score   2.0894

We interpolate and assume  0.9815

P [ X ≤ 2267 ]  =  0,9815

Ths vale already contains th value of   P [ X ≤ 1689 ]  =  0.4327

Then we subtract  to get    0,9815  -  0,4327   = 0,5488

Finally

P [ 1689  ≤   X  ≤  2267 ]  =  0,5488  or  P [  1689  ≤   X  ≤  2267 ]  = 54,88 %
