Answer:

**Answer: x=2 Please mark as brainliest**

**Step-by-step explanation: 16+7+4x=x+3x+7**

Trick or treaters arrive to your house according to a Poisson process with a constant rate parameter of 20 per hour. Suppose you begin sitting on your front porch, observing these arrivals, at some point in time. Suppose a trick or treater arrived 30 minutes ago, but there have been none since. What is the expected value of interarrival time (in minutes) from the previous trick or treater to the next one

B. $465.00

C. $906.93

D. $326.49

**Answer:**

A. $441.93

**Step-by-step explanation:**

Given that Nevaeh took out a 20-year loan for $155,000 at 3.6% interest, compounded monthly and her monthly payment on the loan is $906.93

Let us calculate EMI schedule for 155000 for 20 years

Out of EMI 906.93, 441.93 will be for note reduction.

There are four options given as

A. $441.93

B. $465.00

C. $906.93

D. $326.49

Correct answer is option A) 441.93$

b. Calculate the interval μ±2σμ±2σ. What values of the binomial random variable x fall into this interval?

c. Find P(6≤≤x$\leq$14). How does this compare with the fraction in the interval μ±2σμ±2σ for any distribution? For mound-shaped distributions?

**Answer:**

Explained below.

**Step-by-step explanation:**

Let the random variable *X* be defined as the number of Americans who travel by car look for gas stations and food outlets that are close to or visible from the highway.

The probability of the random variable *X* is: **p**** = 0.40**.

A random sample of **n ****=25 **Americans who travel by car are selected.

The events are independent of each other, since not everybody look for gas stations and food outlets that are close to or visible from the highway.

The random variable *X* follows a Binomial distribution with parameters *n* = 25 and *p* = 0.40.

(**a**)

The mean and variance of X are:

Thus, the mean and variance of X are **10** and **6** respectively.

(**b**)

Compute the values of the interval μ ± 2σ as follows:

Compute the probability of P (5 ≤ X ≤ 15) as follows:

Thus, **97.72% **values of the binomial random variable x fall into this interval.

(**c**)

Compute the value of P (6 ≤ X ≤ 14) as follows:

The value of P (6 ≤ X ≤ 14) is **0.9361**.

According to the Tchebysheff's theorem, for any distribution 75% of the data falls within μ ± 2σ values.

The proportion 0.9361 is very large compared to the other distributions.

Whereas for a mound-shaped distributions, 95% of the data falls within μ ± 2σ values. The proportion 0.9361 is slightly less when compared to the mound-shaped distribution.

The mean of x is 10 and the variance is 6. The **interval **μ ± 2σ is 10 ± 2√6. P(6 ≤ x ≤ 14) can be calculated using the binomial probability formula.

To find the mean of x, we multiply the sample size (n) by the probability of success (p), which is 40% or 0.4. So, the mean (μ) is 0.4 * 25 = 10. To find the variance of x, we multiply the sample size (n) by the probability of success (p) and the probability of failure (1-p), which is 0.6. So, the variance is 25 * 0.4 * 0.6 = 6.

To calculate the interval μ ± 2σ, we need to find the standard deviation (σ) first. The standard deviation is the square root of the variance, so σ = √6. Then, the interval is μ ± 2σ. Plugging in the values, the interval is 10 ± 2√6. To find the values of x that fall into this interval, we can **subtract **and add 2√6 from the mean, resulting in the range 10 - 2√6 to 10 + 2√6.

To find P(6 ≤ x ≤ 14), we need to find the probability of x being between 6 and 14. We can use the binomial probability formula to calculate this. P(6 ≤ x ≤ 14) = P(x = 6) + P(x = 7) + ... + P(x = 14). Using a binomial probability table or a calculator, we can find the probabilities of each x value and sum them up.

Perimeter is the sum of all sides of the polygons.

For a circle, it's called circumference

For Example

The triangle has three sides long 3 4 5 cm

perimeter = 3+4+5 =12 cm

The circle has a radius long 7 cm

circumference = 2πr = 14π cm

Answer: growth, rate is 95.8%

The base 1.958 is in the form 1+r where

1+r = 1.958

r = 1.958-1

r = 0.958

r = 95.8%

The value of r is positive indicating we have growth.

Contrast this to something like 1+r = 0.8 and that solves to r = -0.20 = -20% to indicate decay of 20%. In other words, if the base were some positive number less than 1, then you have decay. Otherwise, you have growth.

The initial value 880 does not affect the answer, so we completely ignore it.

The **value **of 8x + 2x when x = 6 is 60

**What is an Equation?**

**Equations **are mathematical statements with two algebraic **expressions **flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the **expressions **printed on the left and right sides.

**Coefficients**, **variables**, **operators**, **constants**, **terms**, **expressions**, and the equal to sign are some of the components of an **equation**. The "=" sign and terms on both sides must always be present when writing an **equation**.

Given data ,

Let the **equation **be A = 8x + 2x

The **value **of x = 6

**Substituting **the **value **of x in the **equation **, we get

A = 8x + 2x

A = 8 ( 6 ) + 2 ( 6 )

A = 48 + 12

A = 60

Therefore , the **value **of A = 60

Hence , the **value **of 8x + 2x when x = 6 is 60
