The inequality that represents the possible values for the number of hours babysitting and the number of hours landscaping is 12b + 8l ≥ 140.

A mathematical inequality is a statement that two quantities or expressions are not equal. Inequalities are used to compare the relative sizes of numbers or variables and represent constraints or conditions in various contexts, such as optimization problems, systems of linear equations, or financial planning.

Here we have

Harper is working two summer jobs, making $12 per hour babysitting and $8 per hour landscaping. Harper must earn no less than $140 this week.  

Let Harper work for 'b' hours in the baby setting and l hours in landscaping

The amount earned by Haper by babysitting = $ 12 × b = 12b

The amount earned by Haper by landscaping = $ 8 × l = 8l

Here the amount should not be less than $ 140

=> 12b + 8l ≥ 140

Hence,

Answer:

Let’s start by defining the variables:

Let x be the number of rings manufactured per day.

Let y be the number of chains manufactured per day.

The total number of rings and chains manufactured per day is at most 24. Therefore, we have:

x + y ≤ 24

It takes 1 hour to make a ring and 30 minutes to make a chain. Therefore, we have:

1x + 0.5y ≤ 16

The profit on each ring is Rs. 300 and that on each chain is Rs. 190. Therefore, the total profit can be calculated as:

Total Profit = 300x + 190y

We want to maximize the total profit. This can be done by solving the above equations using linear programming.

The solution to this problem is x = 12 and y = 12. Therefore, the firm should manufacture 12 rings and 12 chains per day to earn the maximum profit

By the angle-angle-side theorem, triangles ∠ACE and ∠ECA are congruent, and we can conclude that:

AC = EC.

What is the congruent angle?

When two parallel lines are cut by a transversal, the angles that are on the same side of the transversal and in matching corners will be congruent.

Since AB || DE and BC = DC, we can use the alternate interior angles theorem to conclude that angle BCA is congruent to angle DCE:

∠BCA = ∠DCE

We also know that angles ∠BAC and ∠ACD are supplementary:

∠BAC + ∠ACD = 180 degrees

Since AB || DE, we can use the corresponding angles theorem to conclude that ∠BAC is congruent to  ∠ECD:

∠BAC = ∠ECD

Substituting this into the equation above, we get:

∠ECD + ∠ACD = 180 degrees

Simplifying this equation, we get:

∠ECA = 180 degrees - ∠ACD

Also, ∠DCE is supplementary to ∠ACD, so:

∠DCE + ∠ACD = 180 degrees

Substituting this into the equation above, we get:

∠ECA = ∠DCE

Since angles ∠ECA and ∠DCE are congruent, we can use the vertical angles theorem to conclude that angles ∠ACE and ∠AEC are congruent:

∠ACE = ∠AEC

Therefore, by the angle-angle-side theorem, triangles ∠ACE and ∠ECA are congruent, and we can conclude that:

The answers to the questions are as follows a)50  out of the 200 vehicles will fail in their first 2 years. b)The approximate probability that 50 or more vehicles fail in their first 2 years is essentially zero. c) the approximate probability that no more than 10 of the remaining vehicles fail in their first 2 years is essentially zero.

(a) The average lifespan of the vehicle follows an exponential distribution with a rate parameter of λ = 1/8 since the average lifespan is 8 years. Let X be the number of vehicles that fail in their first 2 years. Then X follows a Poisson distribution with parameter λt, where t is the time period of interest, which is 2 years. Therefore, the expected number of vehicles that fail in their first 2 years is E(X) = λt = (1/8)*2 = 1/4. So we would expect 1/4 * 200 = 50 of the 200 vehicles to fail in their first 2 years.

(b) The number of vehicles that fail in their first 2 years follows a Poisson distribution with parameter λt = 1/4. To approximate the probability that 50 or more of them fail in their first 2 years, we can use the normal approximation to the Poisson distribution. The mean of the normal distribution is μ = λt = 1/4, and the variance is σ^2 = λt = 1/4.

Therefore, the standard deviation is σ = [tex]\sqrt{\frac{1}{4} }[/tex]= 1/2. To standardize the random variable X, we use the formula Z = (X - μ)/σ. Therefore, Z = (50 - 1/4)/(1/2) = 99.5. Using a standard normal distribution table or calculator, the probability of Z being greater than or equal to 99.5 is essentially zero, so the approximate probability that 50 or more vehicles fail in their first 2 years is essentially zero.

(c) Given that 30 vehicles have already failed in under 2 years, 170 vehicles are remaining. We want to find the probability that no more than 10 fail in their first 2 years. Since the number of vehicles that fail in their first 2 years follows a Poisson distribution with parameter λt = 1/4, the number of vehicles that do not fail in their first 2 years follows a Poisson distribution with parameter μ = λt * (number of remaining vehicles) = (1/4)*170 = 42.5. Therefore, the probability that no more than 10 of the remaining vehicles fail in their first 2 years is the same as that a Poisson distribution with parameter 42.5 is less than or equal to 10.

The resulting Z-score is Z = (10 - 42.5)/sqrt(42.5) = -6.72. Using a standard normal distribution table or calculator, the probability of Z being less than or equal to -6.72 is essentially zero, so the approximate probability that no more than 10 of the remaining vehicles fail in their first 2 years is essentially zero.

y = x² + 5

Since the equation is unchanged when x is replaced by (-x), the graph is symmetric with respect to the y-axis.

We can also see that the graph is not symmetric with respect to the x-axis or the origin. To check for symmetry with respect to the x-axis, we can substitute (-y) for y in the equation:

We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2. By finding the Opposites of 2 and n and comparing them, we can write an inequality that is correct based on the number line.

The opposite of -4 1/2 is 4 1/2. This is because the opposite of a number is the number that is the same distance from 0 on the number line, but in the opposite direction. On a number line, -4 1/2 is to the left of 0, so its opposite, 4 1/2, is to the right of 0.

Looking at the number line, we can see that the number 2 is to the right of -4 1/2, but to the left of 4 1/2. Any number greater than 3, represented by n, is also to the right of -4 1/2.

The opposite of 2 is -2 and the opposite of n is -n. So, the inequality we can write is:

-n < -2

This is because -2 is to the left of -n on the number line. We can see that this inequality is correct on the number line because -2 is closer to 0 than -n, which means that -n is less than -2.

In summary, the opposite of -4 1/2 is 4 1/2, and it is related to -4 1/2 because they are the same distance from 0 on the number line, but in opposite directions. We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2. By finding the opposites of 2 and n and comparing them, we can write an inequality that is correct based on the number line.

The probability that the respondent has a pet given that the respondent has had a pet is approximately 0.519, or 51.9%.

To calculate the probability that a respondent has a pet given that they have had a pet, we can use Bayes' theorem:

P(Have a pet | Have had a pet) = P(Have had a pet | Have a pet) * P(Have a pet) / P(Have had a pet)

We are given that:

P(Have a pet) = 0.41

P(Have had a pet) = 0.79

We don't know P(Have had a pet | Have a pet), but we can use the fact that anyone who has a pet has also had a pet, so:

P(Have had a pet | Have a pet) = 1

In mathematics, factorization (also known as factoring) is the process of finding the factors of a given mathematical expression or number. A factor is a number or expression that divides another number or expression exactly, leaving no remainder.

For example, the factors of 6 are 1, 2, 3, and 6 because these are the numbers that divide 6 exactly with no remainder. Similarly, the factors of x² - 4 are (x+2)(x-2) because when we multiply these two expressions together, we get x² - 4.

If -4 is a zero of f(x), then x+4 is a factor of f(x) by the factor theorem

f(x) = (x+4)(3x² - 5x - 78)

To factor the quadratic further, we can use the quadratic formula or factoring by grouping:

3x² - 5x - 78 = 0

x = (5 ± √(5² + 4(3)(78))) / (2(3))

x = (5 ± 19) / 6
