Last question please that I need

Answers

The proper perpendicular slope should be -1/4 instead of positive 1/4. The y intercept is also incorrect

Let's call the y intercept b for now
m = -1/4 is the perpendicular slope
(x,y) = (16,1) is the point the perpendicular line goes through
breaking this down further means x = 16 and y = 1 pair up together

y = mx+b
y = (-1/4)*x+b ... replace m with -1/4
y = (-1/4)*16+b .... replace x with 16
1 = (-1/4)*16+b .... replace y with 1
1 = -4+b ... multiply -1/4 and 16 to get -4
1+4 = -4+b+4 ... add 4 to both sides
5 = b
b = 5
So the y intercept is 5 (not 4)

since m = -1/4 and b = 5  we go from 
y = mx+b
to
y = (-1/4)x+5

So the final answer is y = (-1/4)x+5 which can be written as [tex]y = -\frac{1}{4}x+5[/tex]

As a check, we can plug x = 16 into the equation to get...
y = (-1/4)*x + 5
y = (-1/4)*16 + 5
y = -4 + 5
y = 1
so that confirms we have the right answer.

Lisa wants to buy a phone card for $5. Company X charges $0.49 for the first minute and $0.16 for each additional minute. Company Y charges $0.57 for the first minute and $0.12 for each additional minute. If Lisa makes just one call, which phone company gives her more minutes for $5? How many more minutes?

Answers

So for $5, let's calculate each company's minutes for that much money.

Company X: First subtract the time for the first minute.

5 - 0.49 = 4.51

Then divide by 0.16, and you get about 28 minutes.

28 + the original 1 minute = 29 minutes

Company Y: $5 - 0.57 = 4.43

4.43 / 0.12 = about 36 + the original one minute = 37 minutes

So Company Y gives her more minutes for 5 dollars, and also 8 more.

What is the volume in cubic yards of a greenhouse that is 35 feet long, 10 feet wide, and 10 feet high?

Answers

Final answer:

To determine the volume of a greenhouse, multiply its length, width, and height to find its volume in cubic feet, then convert to cubic yards using the conversion factor of 1 cubic yard being equivalent to 27 cubic feet. The volume for the given dimensions is approximately 129.63 cubic yards.

Explanation:

The volume of a structure, including a greenhouse, is calculated by multiplying its length by its width by its height. The first step is to calculate the volume in cubic feet, then convert cubic feet to cubic yards knowing that 1 cubic yard equals 27 cubic feet. Here's how to calculate the volume of the given greenhouse:

Multiply the length, width, and height in feet to get the volume in cubic feet: 35 ft x 10 ft x 10 ft = 3500 cubic feet.Convert cubic feet to cubic yards using the conversion factor (1 cubic yard = 27 cubic feet): 3500 cubic feet

Step-by-step explanation:

(b) what is the probability that more than eleven loads occur during a 4-year period

Answers

In a 4-year period, expect around 2 loads (Poisson model). Over 11 loads is likely (80% chance). No loads for 5.8 years or more guarantees under 30% chance.

In a Poisson process with a mean time between occurrences of λ = 0.4 years, we can answer your questions as follows:

**(a) Expected number of loads in 4 years:**

The expected number of events in a Poisson process is the product of the mean occurrence rate (λ) and the time interval (t). Therefore, in a 4-year period, you can expect:

Expected loads = λ * t = 0.4 years/load * 4 years ≈ 1.6 loads

However, since the Poisson process deals with discrete events, the expected value doesn't necessarily translate to an exact number of occurrences. It represents the average number of loads you would expect to see over many repetitions of the same 4-year period.

**(b) Probability of more than 11 loads in 4 years:**

To calculate the probability of more than 11 loads, we need to find the probability of 12 or more loads. In a Poisson process, the probability of k events occurring in a time interval t is given by:

P(k events) = (e^(-λt) * (λt)^k) / k!

For k = 12 and λt = 4 * 0.4 = 1.6:

P(more than 11 loads) = 1 - P(0 loads) - P(1 load) - ... - P(11 loads)

≈ 1 - (e^(-1.6) * 1.6^0) / 0! - (e^(-1.6) * 1.6^1) / 1! - ... - (e^(-1.6) * 1.6^11) / 11!

≈ 1 - 0.1995 ≈ 0.8005

Therefore, the probability of having more than 11 loads in a 4-year period is approximately 0.801 (rounded to three decimal places).

**(c) Time period for at most 0.3 probability of no loads:**

We want to find the time period (t) where the probability of no loads (P(0 loads)) is at most 0.3. In other words, we need to solve:

P(0 loads) = e^(-λt) ≤ 0.3

Taking the natural logarithm of both sides and rearranging:

t ≥ -ln(0.3) / λ ≈ 2.303 / 0.4 ≈ 5.76 years

Therefore, the time period must be at least 5.76 years (rounded to four decimal places) for the probability of no loads to be at most 0.3.

The probable question may be:

An article suggests that a Poisson process can be used to represent the occurrence of structural loads over time. Suppose the mean time between occurrences of loads is 0.4 year.

(a) How many loads can be expected to occur during a 4-year period?

(b) What is the probability that more than eleven loads occur during a 4-year period? (Round your answer to three decimal places.)

(c) How long must a time period be so that the probability of no loads occurring during that period is at most 0.3? (Round your answer to four decimal places.)

Pi × radius^2. Radius=20 m Pi × 20^2 Area= 400pi m^2

Answer:  The required area of the given circle is [tex]400\pi~\textup{m^2}.[/tex]

Step-by-step explanation:  We are given that the diameter of a circle i 40 m.

We are to find the area of the circle in terms of pie.

We know that

the AREA of a circle with radius of length r units is given by

[tex]A=\p r^2.[/tex]

Since the diameter of the given circle is 40 m, so the length of the radius is given by

[tex]r=\dfrac{40}{2}=20~\textup{m}.[/tex]

Therefore, the AREA of the circle is given by

[tex]A=\pi r^2=\pi\times 20^2=400\pi~\textup{m}^2.[/tex]

Thus, the required area of the given circle is [tex]400\pi~\textup{m}^2.[/tex]

Find p((5 on green die and 3 on red die) or (3 on green die and 5 on red die)). (enter your answer as a fraction.)

Answers

1/72 This is because the odds that, on two dice, two specific numbers get rolled is 1/36. But since the number has to be rolled on a specific dice, that doubles the fraction.

The probability of rolling a 5 on the green die and a 3 on the red die, or a 3 on the green die and a 5 on the red die is calculated by summing their individual probabilities, leading to a final probability of 1/18.

To solve this probability question, we will use the fundamental counting principle and basic probability rules. We have two six-sided dice, one green and one red. The question specifies two separate events:

The green die shows a 5 and the red die shows a 3.

The green die shows a 3 and the red die shows a 5.

Since each face on a fair six-sided die has an equal chance of appearing, the probability of getting any specific number is 1/6. When we roll two dice, the probability of any specific outcome is (1/6) x (1/6), which simplifies to 1/36.

Since there are two independent events that satisfy the question, we can add the probabilities of each event occurring:

Probability of a 5 on green die and 3 on red die = 1/36

Probability of a 3 on green die and 5 on red die = 1/36

Adding them up, we get 1/36 + 1/36 = 2/36, which simplifies to 1/18. Therefore, the probability of getting either a (5 on the green die and 3 on the red die) or (3 on the green die and 5 on the red die) is 1/18.
