Answer:
Common ratio, r = 3
Step-by-step explanation:
Common ratio is given by the ratio of one of the terms to the previous term and is a constant for the entire sequence
Here the first term is 17
Second term is 51
Second Term ÷ First Term
= 51 ÷ 17 =3
Third Term ÷ Second Term
= 153 ÷ 51 = 3
So common ratio is 3
In general, if aₙ is the nth term and aₙ₊₁ then the common ratio is given by:

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.2%
Answer:
Alright, so we want to know how much that can be earned in one year. So that's going to be 3000. And this is simple interest. So this is one plus 0.011, which equals $3,033. And that's the solution to this exercise.
Answer:
$3,036
Step-by-step explanation:
The new customer can open a money market account. The bank will deposit $3,000 into the account.
The bank will pay 1.2% (0.012) in interest every year. This interest will increase the original amount to $3,036.
According to a 2009 Reader's Digest article, people throw away approximately 13% of what they buy
at the grocery store. Assume this is the true proportion and you plan to randomly survey 90 grocery
shoppers to investigate their behavior. What is the probability that the sample proportion exceeds
0.12?
Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations.
(Enter your answer as a number accurate to 4 decimal places.)
The probability that the sample proportion exceeds 0.12 is given as follows:
0.6103 = 61.03%.
How to obtain probabilities using the normal distribution?
The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].The parameters of the binomial distribution are given as follows:
n = 90, p = 0.13.
Hence the mean and the standard error are given as follows:
[tex]\mu = 0.13[/tex][tex]s = \sqrt{\frac{0.13(0.87)}{90}} = 0.0354[/tex]The probability that the sample proportion exceeds 0.12 is one subtracted by the p-value of Z when X = 0.12, hence:
Z = (0.12 - 0.13)/0.0354
Z = -0.28
Z = -0.28 has a p-value of 0.3897.
Hence:
1 - 0.3897 = 0.6103.

The area of the given composite shape with two rectangles is 68 m²
What is a rectangle?
There are four right angles on the quadrilateral that forms the rectangle. Every corner or vertex has a right angle where the two sides meet. It differs from a square, which has all of its sides of equal length, in that the opposite sides of the rectangle are equal in length. Two dimensions and flatness combine to make a rectangle.
The figure can be divided into a rectangle with a length of 8m and breadth of 6m and another rectangle of length 5m and breadth = (10-6) = 4m.
To find the area of the whole figure, we first find the areas of small and big rectangles and sum their areas.
Area of small rectangle = length * breadth = 5*4 = 20 m²
Area of big rectangle = length * breadth = 8 * 6 = 48 m²
Therefore the area of the given composite shape with two rectangles is 20+48 = 68 m².

RATE c/kWh (Including vat) sell price for the units-cost price for the units 144,72 186,06 261,87 308,37 ✓ 1000z IC) 2
Answer:
Step-by-step explanation:
1.1. Advantages of Selling Prepaid Electricity
Two advantages of selling prepaid electricity are:
a) Reduced costs for the municipality: Prepaid meters eliminate the need for the municipality to send meter readers to each property and manually read the meter. This can save the municipality time and money.
b) Improved cash flow: By receiving payment before the electricity is used, the municipality can improve its cash flow as it will have funds available to purchase more electricity.
1.2. Number of Units Mr Nkomo Received When He Bought Prepaid Electricity for R68,02
The rate per kWh including VAT is R1,33. To determine the number of units Mr Nkomo received, we can use the formula:
Units = Amount / Rate
Units = R68,02 / R1,33
Units = 51.04 kWh
So, Mr Nkomo received 51.04 kWh of electricity when he bought prepaid electricity for R68,02.
1.3. Cost of 310 kWh of Electricity
The rate per kWh including VAT is R1,33. To determine the cost of 310 kWh of electricity, we can use the formula:
Cost = Units * Rate
Cost = 310 kWh * R1,33
Cost = R411,30
So, Mr Nkomo will have to pay R411,30 for 310 kWh of electricity.
1.4. Percentage Profit the Municipality Makes When a Customer Buys 290 kWh of Electricity
To determine the percentage profit the municipality makes when a customer buys 290 kWh of electricity, we need to calculate the cost price and the selling price of the electricity. The cost price of electricity is R1,33 per kWh. The selling price is given in the table as R144,72 for 2-50 kWh, R186,06 for 51-350 kWh, R261,87 for 351-600 kWh, and R308,37 for over 600 kWh.
Since the cost price is R1,33 per kWh and the selling price is different for different ranges of units, we need to calculate the cost and selling price for each range of units and find the average.
For 2-50 kWh:
Cost = 2-50 kWh * R1,33
Cost = 50 kWh * R1,33
Cost = R66,50
Selling price = R144,72
Profit = Selling price - Cost
Profit = R144,72 - R66,50
Profit = R78,22
Percentage profit = (Profit / Cost) * 100
Percentage profit = (R78,22 / R66,50) * 100
Percentage profit = 17.7%
For 51-350 kWh:
Cost = 51-350 kWh * R1,33
Cost = 350 kWh * R1,33
Cost = R466,50
Selling price = R186,06
Profit = Selling price - Cost
Profit = R186,06 - R466,50
Profit = R29,56
Percentage profit = (Profit / Cost) * 100
Percentage profit = (R29,56 / R466,50) * 100
Percentage profit = 6.3%
For 351-600 kWh:
Cost = 351-600 kWh * R1,33
Cost = 600 kWh * R1,33
Cost = R798,00
Selling price = R261,87
Profit = Selling price - Cost
Profit = R261,87 - R798,00
Profit = -536,13
Percentage profit = (Profit / Cost) * 100
Percentage profit = (-536,13 / R798,00) * 100
Percentage profit = -67.3%
For over 600 kWh:
Cost = over 600 kWh * R1,33
Cost = R1,33 * 1000
Cost = R1330,00
Selling price = R308,37
Profit = Selling price - Cost
Profit = R308,37 - R1330,00
Profit = -1021,63
Percentage profit = (Profit / Cost) * 100
Percentage profit = (-1021,63 / R1330,00) * 100
Percentage profit = -76.7%
The average percentage profit for the municipality is calculated by finding the total profit and total cost for each range of units and then dividing the total profit by the total cost.
For the range 2-50 kWh, the total profit is R78,22 and the total cost is R66,50, so the average percentage profit is (R78,22 / R66,50) * 100 = 17.7%.
For the range 51-350 kWh, the total profit is R29,56 and the total cost is R466,50, so the average percentage profit is (R29,56 / R466,50) * 100 = 6.3%.
For the range 351-600 kWh, the total profit is -536,13 and the total cost is R798,00, so the average percentage profit is (-536,13 / R798,00) * 100 = -67.3%.
For the range over 600 kWh, the total profit is -1021,63 and the total cost is R1330,00, so the average percentage profit is (-1021,63 / R1330,00) * 100 = -76.7%.
The average percentage profit for the municipality for the four ranges of units is calculated as follows:
Average percentage profit = (17.7% + 6.3% - 67.3% - 76.7%) / 4
Average percentage profit = -34.05%
Therefore, Mr Nkomo's claim that the percentage profit the municipality makes when a customer buys 290 kWh of electricity is more than 34% is NOT VALID.

↑Multiply Both sides by 1 ↑ ??? ↑ ???
Does this make sense?
Answer:
Step-by-step explanation:
The square root of a number can be both positive and negative, so to find all possible values of d, we need to take both the positive and negative square root of 3520.
Starting with the positive square root:
d = √3520 = √(55^2 * 8) = 55 * √8 = 8 * √55
And for the negative square root:
d = - √3520 = - √(55^2 * 8) = - 55 * √8 = - 8 * √55
So the two possible values of d are 8√55 and -8√55.

¿Qué volumen de solución de ácido a 60% debe mezclarse con una solución a 30% para producir
300 mililitros de solución al 50%?
Answer:
Step-by-step explanation:
To solve this problem, we must first use an equation that reflects the amount of acid in each solution and its relationship to the total volume of the resulting solution. We can use the following equation:
(C1 * V1) + (C2 * V2) = (C3 * V3)
Where:
C1 = concentration of the acid solution at 60% (in percent)
V1 = volume of the acid solution at 60% (in ml)
C2 = concentration of the acid solution at 30% (in percent)
V2 = volume of the 30% acid solution (in ml)
C3 = concentration of the resulting 50% acid solution (in percent)
V3 = volume of the resulting 50% acid solution (in ml)
In this case, we know the total volume of the resulting solution (V3 = 300 ml) and the desired concentration (C3 = 50%). We also know the concentration of one of the original solutions (C1 = 60%). So we can plug the known values into the equation:
(60 * V1) + (30 * V2) = (50 * 300)
Clearing V1:
V1 = (300 * 50 - 30 * V2) / 60
Now that we have V1 as a function of V2, we can solve the problem to find the volume of the 60% acid solution to mix with the 30% solution. Substitute the known values into the equation:
V1 = (300 * 50 - 30 * V2) / 60
V1 = (15000 - 30 * V2) / 60
V1 = 250 - (V2 / 2)
We can use this last equation to find the volume of the 30% solution that we must mix with the 60% solution:
V2 = 2 * (250 - V1)
Clearing V1:
V1 = 250 - (V2 / 2)
V1 = 250 - (2 * (250 - V1) / 2)
V1 = 250 - 250 + V1
V1 = 250
Therefore, we must mix 250 ml of 60% acid solution with 250 ml of 30% solution to produce 300 ml of 50% solution.

7512/9390 is 0.8 & 1878/9390 is 0.2
As a percentage that is 80% and 20%.
This means that the new amount of sugar only makes up 80% of the old amount. That means that there was a decrease of 20% of kilograms of sugar.
I hope this helped & Good Luck <3 !!!
f(x) = 12 + 1
(f + g) (x) =
g(x) = 5 - x
Answer:
Step-by-step explanation: The expression for f(x) is not a valid mathematical equation. It should specify the relationship between x and the output value of f(x). If the correct equation for f(x) is given, we can then find the expression for (f + g)(x) and g(x).
Assuming that the equation for f(x) is as follows:
f(x) = 12 + x
Then, the expression for (f + g)(x) can be found by adding f(x) and g(x):
(f + g)(x) = f(x) + g(x) = 12 + x + (5 - x) = 17
So, (f + g)(x) is a constant function with a value of 17 for all values of x.
And the expression for g(x) was already given:
g(x) = 5 - x

The equation of line passing through the points (-2, 4) & (4, 2) is :
y = -1/3 x + 6
The value of b = 6
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
To find the equation of the line passing through the two points (-2, 4) and (4, 2), we can use the point-slope form of a line. The point-slope form of a line is given by:
y - y₁ = m(x - x₁)
where m is the slope of the line and (x₁, y₁) is any point on the line.
To find the slope of the line, we can use the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) and (x₂, y₂) are the two given points.
Plugging in the values for the given points, we get:
m = (2 - 4) / (4 - (-2))
m = -2 / 6
m = -1/3
Next, we can use one of the given points to write the equation in point-slope form:
y - 4 = -1/3 (x - (-2))
y - 4 = -1/3 x + 2
y = -1/3 x + 6
This is the equation of the line passing through the two given points (-2, 4) and (4, 2).
