Answer:

- 8x > 24

Step-by-step explanation:

Given

- 6x - 10 > 14 + 2x ( subtract 2x from both sides )

- 8x - 10 > 14 ( add 14 to both sides )

- 8x > 24 ← required missing step

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.

x < - 3 ← is the solution

Answer:

Complete question:

Emily convinced her mom to buy a giant box of her favorite cereal. Her mom doesn't think the box will fit on their shelf. The volume of the box is 10,000 cm^3 cubed. The base of the box is 25cm by 10cm.

How tall is the box of cereal?

Answer: 40cm

Step-by-step explanation:

Given that :

A box is normally in the shape of a cube

formula of volume of a cube;

We want to find the height(tallness)

Volume=LengthxWidthxHeight

Volume = 10,000cm^3

Base of box = 25cm by 10cm,

Base of box = Length × width

Therefore:

Length = 25cm, Width = 10cm

Volume = Lengh × Width × Height

10,000cm^3 = 25cm × 10cm × Height

10,000cm^3 = 250cm^2 × Height

Height = 10,000cm^3 ÷ 250cm^2

Height = 40cm

5x^4 - 6x^7 + 1  is a rational function.

A rational function is one that can be written as a polynomial divided by a polynomial. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator.

As, the rational function are written as

P(x)/ Q(x), Q(x)≠0

So,

5x^4 - 6x^7 + 1 can be written as 5x^4 - 6x^7 + 1 /1.

So, 5x^4 - 6x^7 + 1  is a rational function.

The answer is 21:7 and 15: 5 are equivelent to 6:2

Step-by-step explanation:

The distance covered (in km) by a bike in 4 minutes at a speed of 63 km/hr is 4.2km

Given that a bike covered a certain distance in 4 minutes and at a speed of 63 km/hr.

We need to find the distance covered by the bike in km.

As per the formula, speed = distance/time, and the given speed of the bike is 63 km/hr.

we know that

1 hr = ( 60 × 60 ) sec = 3600 sec

1 km = 1000 m

so now the speed becomes,

63 km = 63×1000 = 63000 m

here,

speed = distance/time

speed = 63000/3600

speed = 35/2

speed = 17.5 m/s

as per the question we have to find, the distance covered by bike in 4 minutes.

4 minutes = ( 4 × 60 )sec = 240 sec

So,

The distance covered by bike in 4 minutes = 17.5 × 240 = 4200 m or 4.2 km

Hence, The distance covered (in km) by a bike in 4 minutes at a speed of 63 km/hr is 4.2 km

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

Step-by-step explanation:

We know that

Perimeter of rectangle = 2(l + w)

Let the width be w

=> 104 = 2(32 + w)

=> 104/2 = 32 + w

=> 52 = 32 + w

The height of the skyscraper is 174.01 m when Tyler is standing at a horizontal distance of 1 m.

The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides. There are five fundamental trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.

Let the height of the skyscraper = x.

Given that, he is standing at a horizontal distance of 1 meters from the base of the skyscraper, hence the adjacent distance = 1 m.

The angle of elevation is 57 degrees.

Using the trigonometric identities we have:

tan (57) = x / 1

x = 172.46

This is the height of the skyscraper above the eye level.

The total height of the skyscraper is:

172.46 + 1.55 = 174.01 m

To find the probability that a participant selected at random found the products favorable, we can calculate the weighted average of the favorable responses from both the industry-sponsored and non-industry-funded studies.

For the industry-sponsored studies, 65% of participants found the products favorable, and for the non-industry-funded studies, 47% found the products favorable. Since there were 65 industry-sponsored studies and 35 non-industry-funded studies, the overall probability is:

(65/100) * 0.65 + (35/100) * 0.47 = 0.4225 + 0.1645 = 0.587 or 58.7%

If a randomly selected participant found the product favorable, we can use Bayes' theorem to calculate the probability that the study was sponsored by the food industry given this favorable response. The calculation is:

P(Industry-sponsored | Favorable) = (P(Favorable | Industry-sponsored) * P(Industry-sponsored)) / P(Favorable)

P(Favorable | Industry-sponsored) = 0.65

P(Industry-sponsored) = 65/100

P(Favorable) = 0.587

P(Industry-sponsored | Favorable) = (0.65 * (65/100)) / 0.587 ≈ 0.719 or 71.9%

Similarly, if a randomly selected participant found the product unfavorable, we can use Bayes' theorem to calculate the probability that the study had no industry funding given this unfavorable response. The calculation is:

P(No industry funding | Unfavorable) = (P(Unfavorable | No industry funding) * P(No industry funding)) / P(Unfavorable)

P(Unfavorable | No industry funding) = 0.36

P(No industry funding) = 35/100

P(Unfavorable) = 1 - P(Favorable) = 1 - 0.587 = 0.413

P(No industry funding | Unfavorable) = (0.36 * (35/100)) / 0.413 ≈ 0.305 or 30.5%

To determine the margin of error (E) used to construct the confidence interval, we need to consider the formula for the margin of error in estimating a proportion:

E = Z * sqrt((p * q) / n)

Where:

- Z is the z-score corresponding to the desired confidence level (90% in this case)

- p is the estimated proportion of airline reservations being canceled

- q is the complement of p (1 - p)

- n is the sample size

Since the confidence interval is already given, we can determine the estimated proportion by taking the average of the lower and upper bounds:

p = (0.027 + 0.037) / 2 = 0.032

Next, we need to find the z-score corresponding to a 90% confidence level. Since the confidence interval is symmetric, we can use the standard normal distribution table or calculator to find the z-score that corresponds to a 95% confidence level (which is 1 - (1 - 0.90) / 2 = 0.95).

The z-score for a 95% confidence level is approximately 1.645.

Now we can calculate the margin of error:

E = 1.645 * sqrt((0.032 * (1 - 0.032)) / n)

Since the sample size (n) is not provided in the given information, we cannot calculate the exact margin of error.

The probability that a randomly selected group of 16 individuals from the campus will be selected is 0.8023 or 80.23%

Based on the sign in the elevator of the college library, the limit of 16 persons and weight limit of 2,500 pounds need to be adhered to. To ensure compliance with both limits, we need to consider both the number of people and their weight.

Assuming that the distribution of weights of individuals on campus is approximately normal with an average weight of 155 pounds and a standard deviation of 29 pounds, we can use this information to estimate the total weight of a group of 16 randomly selected individuals.

The total weight of a group of 16 individuals can be estimated as follows:

Total weight = 16 x average weight = 16 x 155 = 2480 pounds

To determine if this total weight is within the weight limit of 2,500 pounds, we need to consider the variability in the weights of the individuals. We can do this by calculating the standard deviation of the total weight using the following formula:

Standard deviation of total weight = square root of (n x variance)

where n is the sample size (16) and variance is the square of the standard deviation (29 squared).

Standard deviation of total weight = square root of (16 x 29^2) = 232.74

Using this standard deviation, we can calculate the probability that the total weight of the group of 16 individuals is less than or equal to the weight limit of 2,500 pounds:

Z-score = (2,500 - 2,480) / 232.74 = 0.86

Using a standard normal distribution table or calculator, we can find that the probability of a Z-score less than or equal to 0.86 is approximately 0.8023.

Therefore, the probability that a randomly selected group of 16 individuals from the campus will comply with both the number and weight limits in the elevator of the college library is approximately 0.8023 or 80.23%.
