house flipping is the buying of a house for a low price with the intention of reselling it for a profit after a short period of time.

Buyers that acquire distressed houses, patch them up, and then resell them for a profit are included. These properties are often found through foreclosures, bank short sales, or property auctions.

To be successful at real estate flipping, you must be able to manage your money properly and invest in inexpensive homes. These are generally properties that need a lot of attention.

Following that, you'll need to spend on modifications that will boost the resale value of the house and draw the attention of a possible buyer. When the improvements are finished, you must list and advertise the home.

The surface area of the resulting solid is 40 cm².

A cube is a three-dimensional figure that has 6 faces and 12 edges and 8 vertices. All of the edges of a cube are of the same length.

If the volume of each of the two cubes is 8 cm³, then the length of its edge is 2 cm.

V = e³

8 = e³

e = 2 cm

Two cubes are glued together. Either side by side or put on top of each other, the dimension of the resulting solid is 4 cm by 2 cm by 2 cm.

Hence, the surface area of the resulting solid is

To find out how many miles per gallon the truck got, we can divide the number of miles it traveled by the number of gallons of gas it used: 84 miles / 4 gallons = <<84/4=21>>21 miles/gallon.

To find out how many miles per gallon the SUV got, we can divide the number of miles it traveled by the number of gallons of gas it used: 72 miles / 3 gallons = <<72/3=24>>24 miles/gallon.

To find out how many more miles per gallon the SUV got than the truck, we can subtract the number of miles per gallon the truck got from the number of miles per gallon the SUV got: 24 miles/gallon - 21 miles/gallon = <<24-21=3>>3 miles/gallon.

The SUV got 3 more miles per gallon than the truck.

Step-by-step explanation:

Let's find Mrs. Robinson first

100% - 20% = 80% or 0.8

29.99 times 0.8% = $24

29.99 -24 = $5.99 off

Now Let's find Mr.Chang

100% - 10% = 90% or 0.9

25 times 0.9% = $22.50

25 - 22.50 = $2.50 off

So Mrs. Robinson received a better discount!

The probability that a teenage boy has a cholesterol level greater than 200 is 0.11507.

Let the distribution of teenage boys' cholesterol levels be x

According to the question,

X follows a Normal distribution with

mean = 170

Standard deviation = 25

Hence, the variance = 25² = 625.

Hence X ~ N(170,25)

Now we need to find P(X>200)

= 1 - P(X<200)

Now to find this we need to convert the problem to a standard normal distribution

for this, we use the formula

P(X<x) = P(Z<x-mean/sd)

Therefore,

P(X<200)

= P(Z<(200 - 170)/25)

= P(Z<30/25)

= P(Z<1.2)

According to Z table,

P(Z<1.2)

= 0.88493

Hence, P(X>200)

= 1 - 0.88493

= 0.11507

Using the concept of asymptote of the function it can be concluded that the number of boxes of cereals sold is 0 after 0 weeks, it will keep falling after reaching the maximum sales and cereals sold is always positive as the cereals introduced so the correct option are A, C and E.

A line that a curve approaches but never touches is an asymptote. The graph of a function converges to a line known as an asymptote, in other words. When graphing functions, asymptotes are usually not necessary to be drawn. The curve must not contact the asymptote when we graph them using dotted lines (imaginary lines). As a result, the asymptotes are merely made-up lines. When either the value of x or y tends to or -, the distance between the asymptote of a function, y = f(x), and its graph is close to zero.

Option A is correct as according to the option A: - B(w)= [tex]\frac{120w}{150+w^{2} }[/tex], w=0.

On putting the value of w=0 in above function implies B(w)=0.

Hence, number of boxes of cereals sold is 0 after 0 weeks.

Option C is correct as function B(w) is decreasing function after reaching its maxima according to graph.

Option E is correct as B(w)= [tex]\frac{120w}{150+w^{2} }[/tex], if w>0

The number of unique orders that Gabriel can arrange for the new flavors of his favourite snak is 6..

The term permutation refers to the mathematical calculation of the number of ways a given set can be arranged. Simply put, permutation is a word that describes the number of ways things can be ordered or arranged. With permutations, the order of placement is important.

P(n,r) = n!/(n-r)!

where n --> total items in the set;

r --> items taken for the permutation;

"!" --> denotes taking the factorial

We have given that,

total possible flavours of Gabriel's favorite snack = 3

He wants to try each of the new flavors one after the other.

We have to calculate the number of ways Gabriel can arrange the new flavors .

For this Use the permutation formula,

ⁿPᵣ = n!/(n-r)!

here , n = 3 , r = 3 then,

P (3,3) = 3!/(3 − 3)!

= 3!/0!

As we know that 0! = 1 so, P(3,3) = 3!

= 3×2×1 (because n! = n(n-1)(n-2)---3.2.1 )

= 6

The value of the given car after 7 years will be $2880 which has been decreasing by 20% every three years.

A car is currently $6,000 and has been decreasing by 20% every three years.

After 7 years, the car will have decreased in value by 7 / 3 = 2 full cycles of 20%.

Each cycle decreases the value of the car by 20/100 × $6,000 = $1200.

After two cycles, the value of the car will be :

$6,000 - 2 × $1,200 = $3,600.

After 7 years, the car will have decreased in value by an additional :

$3,600 × 20/100 = $720.

So, after 7 years, the car will be worth :

$3,600 - $720 = $2880.

Therefore, the value of the given car after 7 years will be $2880.

Therefore , the answer is  the confidence interval is positive, the researcher can conclude there is a greater proportion of men than women who watch television regularly.

A confidence interval in frequentist statistics is a range of estimates for an unobserved parameter. The most common confidence level for computing confidence intervals is 95%, however other levels, including 90% or 99%, are sporadically employed.

Here,

Assuming that the confidence interval's lower and upper bounds are both positive and that it does, then one of the proportions must be larger than the other as the confidence interval's range corresponds to the difference in proportions. Men watch television more frequently than women do (56/70 vs. 47/85, according to a quick calculation of the proportions).

Given, Marry drove 156 miles at a constant rate.

If she had driven 99 miles/hour faster, she could have reduced her driving time by 45 minutes.

we have to find the speed at which Marry was driving.

Let the speed be, v

On using the distance formula, we get

Distance = Speed × Time

156 = vt

If she drive 99 miles/hour faster then her time reduced by 45 min.

156 = (v + 99)(t - 3/4)

156 = 156 + 99t - 3/4v - 297/4

396t = 3v + 297

396t = 468/t + 297

On solving the quadratic equation, we get
