The highest frequency of any score in the histogram would be 5/20 = 0.25.

The score that has the highest frequency is 8. This is determined by counting the number of bars corresponding to each score. In this histogram, there are 5 bars corresponding to the score 8, which is the highest number compared to any other score.

Formulaically, we can calculate the frequency for each score by dividing the number of observations for that score by the total number of observations. For the score 8, this would be 5/20 = 0.25. This is the highest frequency of any score in the histogram.

The molar volume of ethane at 300 K and 200 atm, calculated using the Van der Waals equation of state, is approximately 0.109 L/mol.

To calculate the molar volume, we need to solve the cubic equation obtained from the expanded Van der Waals equation of state:

V^3 - (b + pRT)V^2 + (pa)V - pab = 0

Given the values of a = 5.5088 L^2 atm mol^(-2) and b = 0.065144 L mol^(-1) for ethane gas, and the temperature T = 300 K and pressure p = 200 atm, we can substitute these values into the cubic equation.

Substituting the values into the equation, we have:

V^3 - (0.065144 + (200)(0.0821)(300))V^2 + (5.5088)(200)V - (200)(0.065144)(5.5088) = 0

Solving this cubic equation, we find that one of the roots corresponds to the molar volume of ethane at the given conditions, which is approximately 0.109 L/mol.

Neglect air resistance and assume the ground is level. Therefore, the time taken by the froghopper to reach the maximum height of \(\(70 \: cm\) is \(0.377 \: s\)\)

The froghopper, Philaenus spumarius, holds the world record for insect jumps. When leaping at an angle of ( 58.0 ) degrees above the horizontal, some of the tiny critters have reached a maximum height of 70.0 cm above the level ground.

Find the time that elapses from the beginning of the jump to the top of the trajectory. Neglect air resistance and assume the ground is level.The given problem is about finding the time taken by a froghopper to reach the maximum height of (70 cm) when leaping at an angle of\(\(58.0 \: degrees\)\) above the horizontal.

The given information is that the ground is level, and air resistance is neglected.

To find the time that elapses from the beginning of the jump to the top of the trajectory, we need to use the kinematic equation of motion under free fall.\(\[y = v_0 t + \frac{1}{2}gt^2\]\)

Where,\(\[y = 70.0 \: cm = 0.7 \: m\]\)

(Maximum height) \(\[v_0 = 0\]\)

(Initial velocity) \(\[g = 9.8 \\): \(m/s^2\) (Acceleration due to gravity)

By substituting the given values in the above kinematic equation, we get,\(\[0.7 = \frac{1}{2} \times 9.8 \times t^2\]\)\(\[\Rightarrow t = \sqrt{\frac{0.7 \times 2}{9.8}}\]\)\(\[\Rightarrow t = 0.377 \: s\]\)

Therefore, the time taken by the froghopper to reach the maximum height of \(\(70 \: cm\) is \(0.377 \: s\)\)

Answer:

There are 68,640 different ways the runners can finish first, second, and third in the race.

Concept of Permutations

The number of different ways the runners can finish first, second, and third in a race can be calculated using the concept of permutations.

Brief Overview

Since there are 42 runners competing for the top three positions, we have 42 choices for the first-place finisher. Once the first-place finisher is determined, there are 41 remaining runners to choose from for the second-place finisher. Similarly, once the first two positions are determined, there are 40 runners left to choose from for the third-place finisher.

Calculations

To calculate the total number of different ways, we multiply the number of choices for each position:

42 choices for the first-place finisher × 41 choices for the second-place finisher × 40 choices for the third-place finisher = 68,640 different ways.

Concluding Sentence

Therefore, there are 68,640 different ways the runners can finish first, second, and third in the race.

Answer:

In 25 minutes, the monthly phone charges of both companies will be the same.

Step-by-step explanation:

If we allow m to represent the number of minutes, we can create two equations for C, the total cost of phone charges from both companies:

Phoenix equation:  C = 0.5m + 30

Nuphone equation: C - 0.10m + 40

Now, we can set the two equations equal to each other.  Solving for m will show us how many minutes must Abby use for the total cost at both companies to be the same:

0.5m + 30 = 0.10m + 40

Step 1:  Subtract 30 from both sides:

(0.5m + 30 = 0.10m + 40) - 30

0.5m = 0.10m + 10

Step 2:  Subtract 0.10m from both sides:

(0.5m = 0.10m + 10) - 0.10m

0.4m = 10

Step 3:  Divide both sides by 0.4 to solve for m (the number of minutes it takes for the total cost of both companies to be the same)

(0.4m = 10) / 0.4

m = 25

Thus, Abby would need to use 25 minutes for the total cost at both companies to be the same.

Optional Step 4: Check the validity of the answer by plugging in 25 for m in both equations and seeing if we get the same answer:

Checking m = 25 with Phoenix equation:

C = 0.5(25) + 30

C = 12.5 + 30

C = 42.5

Checking m = 25 with Nuphone equation:

C = 0.10(25) + 40

C = 2.5 + 40

C = 42.5

Thus, m = 25 is the correct answer.

Answer:

  m∠DCE = 58°

  m∠CDE = 74°

  m∠DAE = 119°

Step-by-step explanation:

The incenter is the point of intersection of the angle bisectors. The angles on either side of the bisector have the same measure. Of course, the sum of angles in a triangle is 180°.

  m∠DCE = 2×29° = 58°

  m∠CDE = 180° -58° -2×24° = 74°

  m∠DAE = 180° -74°/2 -24° = 119°

The value of the function at x = 4 is 8.79.

Tangent line approximation is the approximation of any function using a linear function. It is also called as linear approximation.

It allows us to approximate the value of a general function with a more simpler linear function.

Given that,

f(1) = 2

f'(x) = \(\sqrt{x^{2} +2cos x + 3}\)

We have the formula for linear approximation as,

f(x) = f(a) + f'(a) (x - a)

Here x = 4 and a = 1

f(a) = f(1) = 2

f'(a) = f'(1) = \(\sqrt{1^{2} +2cos 1 + 3}\) = 2.254

Substituting,

f(4) = 2 + (2.254) (4 - 1)

     = 8.762 ≈ 8.79

Hence the value of f(4) is 8.79.

the power rule of integration, we get ∫C x^5 y √z dz = (2/23)t^(23/2) | from 0 to 1 = 2/23 The value of the line integral is 2/23.

We need to evaluate the line integral ∫C x^5 y √z dz where C is the given curve x = t^4, y = t, z = t^2, 0 ≤ t ≤ 1.

First, we need to parameterize the curve C as r(t) = t^4 i + t j + t^2 k, 0 ≤ t ≤ 1.

Next, we need to express x, y, and z in terms of t: x = t^4, y = t, and z = t^2.

Then, we can express the integrand in terms of t as follows:

x^5 y √z = (t^4)^5 t √(t^2) = t^21/2

So, the line integral becomes:

∫C x^5 y √z dz = ∫0^1 t^21/2 dt

Using the power rule of integration, we get:

∫C x^5 y √z dz = (2/23)t^(23/2) | from 0 to 1 = 2/23

Therefore, the value of the line integral is 2/23.

Step-by-step explanation:

Let x and y be the per hour price of both activities. This gives us two equations which are:

\((1)2x+5y=205\\(2)3x+3y=240\)

Now we divide equation (2) by 3 so we get the value of y:

\(x+y=80\\y=80-x\)

Then we substitute y into equation (1):

\(2x+5(80-x)=205\\-3x=205-400\\-3x=(-195)\\3x=195\\x=65\)

Now we insert the in the equation we got for y:
