If your business starts with 3% awareness and grows awareness by 5% per week (compounded), how long will it take to reach 75% awareness is b) 66 weeks

Compound growth denotes the procedure of generating profits not only on the investment's principal amount, but also on the accumulated interest.

It is essentially reallocating its earnings where the investor's interest is integrated with the beginning sum, while additional interest is contingent on this amplified amount.

The purposeful act of compounding can yield noteworthy accomplishments over time, since interest earned from pre-existing income inflates drastically in value due to accruing interest outlays, and hence boosts the final outcome substantially and rapidly- resulting in exponential growth of the given input.

Step-by-step explanation:

The sum of the roots of x² - 9x + 8 is 9. The product of the roots of x² - 9x + 8 is 8.

A quadratic equation is a second-degree polynomial equation in one variable, typically written in the form ax² + bx + c = 0, where x is the variable and a, b, and c are constants.

The expression x² - 9x + 8 can be factored as follows:

x² - 9x + 8 = (x - 1)(x - 8)

To check that this factorization is correct, you can expand the expression using the distributive property:

(x - 1)(x - 8) = x² - 8x - x + 8 = x² - 9x + 8

So the factorization is indeed correct.

The sum of the roots of the quadratic equation ax² + bx + c = 0 is given by -b/a, where a, b, and c are the coefficients of the equation. In this case, a = 1, b = -9, and c = 8, so the sum of the roots is:

-sum of roots = -b/a = -(-9)/1 = 9

Therefore, the sum of the roots of x² - 9x + 8 is 9.

The product of the roots of the quadratic equation ax² + bx + c = 0 is given by c/a. In this case, c = 8 and a = 1, so the product of the roots is:

product of roots = c/a = 8/1 = 8

Therefore, the product of the roots of x² - 9x + 8 is 8.

The money in the account will be $252.

For simple interest, use the formula:

I = Prt

where I stands for interest earned, P for principle (amount paid in the beginning), r for yearly interest rate (in decimal form), and t for the time in years.

P equals $200, r equals 0.052, and t equals 5. With these values entered into the formula, we obtain:

I = Prt = ($200)(0.052)(5) = $52

The account will thus have $52 in interest after 5 years. After five years, we add the interest to the principal to determine the account's total balance:

Total = $200 + $52 = $252

Yes, the walls form a right angle.

To determine if the walls form a right angle, we can use the Pythagorean theorem. The question states that a wall 12 feet long makes a corner with a wall that is 14 feet long, and the other ends of the walls are about 18.44 feet apart.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, let's consider the 12-foot and 14-foot walls as the two shorter sides, and the 18.44-foot distance as the potential hypotenuse.

Step 1: Calculate the square of the lengths of the 12-foot and 14-foot walls.

12² = 144

14² = 196

Step 2: Calculate the sum of the squares of these two sides.

144 + 196 = 340

Step 3: Calculate the square of the length of the 18.44-foot distance.

18.44² ≈ 339.95

Since 339.95 is very close to 340, we can conclude that the walls form a right angle.

It will take approximately 1.59 hours to fill the hot tub with a hose that has a filling rate of 4.6 gallons per minute

Assuming that the filling rate of the hose is constant, we can use the formula:

time = volume / rate

where time is the time taken to fill the hot tub, volume is the volume of the hot tub (440 gallons), and rate is the filling rate of the hose (4.6 gallons per minute).

Substituting the values, we get:

time = 440 / 4.6

which simplifies to:

time = 95.65 minutes

To convert minutes to hours, we divide by 60 (since there are 60 minutes in an hour):

time = 95.65 / 60

it will cost Vince $5,175 to get new carpet installed, assuming the area to be covered is 500 square feet.

To calculate the cost for Vince to get new carpet installed, we need to add up the cost of the carpet, padding, labor, and hauling away the old carpet.

Let's assume that the area to be covered is 500 square feet. Then, the cost for each component can be calculated as follows:

Cost of carpet = $8/sq ft * 500 sq ft = $4,000

Cost of carpet padding = $0.30/sq ft * 500 sq ft = $150

Cost of labor = $0.75/sq ft * 500 sq ft = $375

Cost of hauling away old carpet = $1.30/sq ft * 500 sq ft = $650

Total cost = Cost of carpet + Cost of carpet padding + Cost of labor + Cost of hauling away old carpet

= $4,000 + $150 + $375 + $650

With a 99% confidence level, we can say that the true proportion of all homes that have electrical/environmental problems is at least 8.3%.

To calculate a lower confidence bound using a confidence level of 99% for the percentage of all homes that have electrical/environmental problems, we need to have a sample of data on this issue. Let's assume that we have a random sample of 100 homes, and 20 of them were found to have electrical/environmental problems.

To calculate the lower confidence bound, we can use the formula:

Lower bound = p - zα/2 * sqrt(p * (1-p) / n)

where:

p = proportion of homes in the sample that have electrical/environmental problems = 20/100 = 0.2

zα/2 = z-score for the given confidence level of 99% = 2.576 (obtained from a standard normal distribution table or calculator)

n = sample size = 100

Plugging in these values, we get:

Lower bound = 0.2 - 2.576 * sqrt(0.2 * 0.8 / 100) = 0.083

from the sample proportion.

The margin of error can be calculated using the sample proportion, sample size, and the chosen confidence level (in

this case, 99%).

For example, if the sample proportion is 0.25 and the sample size is 100, the margin of error would be 0.075 and the

A z-score is a statistical measurement that indicates how many standard deviations an individual value is from the mean - True.

The mean from the value of interest and dividing the result by the standard deviation.

This standardized score provides a way to compare values from different data sets or populations.

For example, if a student's score on a test is 80 and the mean score for the class is 70 with a standard deviation of 5, the student's z-score would be 2.

This means that the student's score is two standard deviations above the class mean. This information can be useful in understanding the student's performance relative to their peers.

Z-scores can also be used to identify outliers or extreme values in a data set. Values with a z-score greater than 3 or less than -3 are considered to be outliers and may warrant further investigation.

In summary, a z-score is a valuable tool in statistical analysis that measures how many standard deviations a value is from the mean. It provides a standardized way to compare values across different data sets and can help identify outliers or extreme values.
