A bouncy ball is dropped such that the height of its first bounce is 4.5 feet and each successive bounce is 73% of the previous bounce's height. What would be the height of the 10th bounce of the ball? Round to the nearest tenth (if necessary).
The height of the 10th bounce of the ball will be 0.6 feet.
What is geometric sequence?A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
What is the formula for finding the nth term of geometric sequence?The nth term of the geometric sequence is given by
\(\sf T_n=ar^{n-1}\)
Where,
\(\sf T_n\) is the nth term.r is the common ratioa is the first termAccording to the given question.
During the first bounce, height of the ball from the ground, a = 4.5 feet
And, the each successive bounce is 73% of the previous bounce's height.
So,
During the second bounce, the height of ball from the ground
\(\sf = 73\% \ of \ 10\)
\(=\dfrac{73}{100}(10)\)
\(\sf = 0.73 \times 10\)
\(\sf = 7.3 \ feet\)
During the third bounce, the height of ball from the ground
\(\sf = 73\% \ of \ 7.3\)
\(=\dfrac{73}{100}(7.3)\)
\(\sf = 5.33 \ feet\)
Like this we will obtain a geometric sequence 7.3, 5.33, 3.11, 2.23,...
And the common ratio of the geometric sequence is 0.73
Therefore,
The sixth term of the geometric sequence is given by
\(\sf T_{10}=10(0.73)^{10-1\)
\(\sf T_{10}=10(0.73)^{9\)
\(\sf T_{10}=10(0.059)\)
\(\sf T_{10}=0.59\thickapprox0.6 \ feet\)
Hence, the height of the 10th bounce of the ball will be 0.6 feet.

Twenty-five bakery customers were surveyed to determine if they like cake or pie. The results are shown in the venn diagram. Given that a randomly chosen customer likes cake, what is the probability that the customer also likes pie?.
The probability that a randomly chosen customer who likes cake also likes pie is 2/3 or 0.6
To find the probability that a customer who likes cake also likes pie, we need to look at the overlap between the cake and pie circles in the Venn diagram. The diagram shows that 10 customers like both cake and pie, out of a total of 25 customers surveyed.
So, the probability that a randomly chosen customer who likes cake also likes pie is:
P(pie | cake) = number of customers who like both cake and pie / number of customers who like cake
P(pie | cake) = 10/15
P(pie | cake) = 2/3
Therefore, the probability that a randomly chosen customer who likes cake also likes pie is 2/3 or 0.67.

15 For a school project, Leo is making a model of the Statue of Liberty. He is using a scale of2 cm : 3 m. The Statue of Liberty is 93 meters tall. How tall is Leo's model?
SOLUTION
Leo is making a statue. He wants to use 2cm to represent 3m for the statue because it will be difficult making a whole of 93 meters. So to minimize the stress and cost, he dicided to use 2cm for each 3m of the statue of liberty.
Now to find how tall Leo's statue would be, we simply compare the ratios.
That is the measurement of the statue to that of Leo's
\(\frac{93\text{ m}}{3\text{ m }}\text{ = }\frac{x}{2\operatorname{cm}}\)This will help you to determine Leo's statue. Ratio for the staue = Ratio for that of Leo's measurement
\(\begin{gathered} \frac{93\text{ m}}{3\text{ m }}\text{ = }\frac{x}{2\operatorname{cm}} \\ \text{cross multiplying } \\ 3x\text{ = 93}\times2 \\ 3x\text{ = 186 } \\ x\text{ = }\frac{186}{3} \\ \\ x\text{ = 62 cm} \end{gathered}\)Therefore Leo's model would be 62 cm tall
The Gallup Poll interviews 1600 people. Of these, 18% say that they jog regularly. The news report adds: "The poll has a margin of error of plus or minus three percentage points at a 95% confidence level." You can safely conclude that
A. 95% of all Gallup Poll samples like this one give answers within ±3% of the true population value.
B. the percent of the population who jog is certainly between 15% and 21%.
C. 95% of the population jog between 15% and 21% of the time.
D. we can be 95% confident that the sample proportion is captured by the confidence interval.
E. if Gallup took many samples, 95% of them would find that 18% of the people in the sample jog.
The correct answer is option D. We can be 95% confident that the sample proportion is captured by the confidence interval.
The margin of error of plus or minus three percentage points at a 95% confidence level means that the true proportion of people who jog regularly in the population is estimated to be between 15% and 21%. We can be 95% confident that the true proportion of people who jog regularly falls within this interval.
Therefore, option B is correct. Option A is incorrect because it implies that the margin of error always holds true for any sample size, which is not the case. Option C is incorrect because it presents a range of values for the population, not for the estimate. Option E is incorrect because it refers to the proportion of samples that would find the same sample proportion, not the range of values within which the true proportion lies.

(b) Determine the original cost of a car that has a yearly depreciation rate of 11% and is worth $10,000 after 2 yr. Round to the nearest $100.
The original cost of the car was $12,935.74 (rounded to the nearest $100).
(a) To find the depreciation rate for a car that originally cost $20,000 and is worth $12,000 after 4 years, we can use the formula:
\(C = (1 - r)^n * C_0\)
where C is the value of the car after n years, C_0 is the original cost of the car, and r is the yearly depreciation rate.
Plugging in the values given, we get:
\(12,000 = (1 - r)^4 * 20,000\)
Solving for r, we get:
\(1 - r = (12,000/20,000)^(1/4) = 0.8185\)
r = 1 - 0.8185 = 0.1815
The depreciation rate for the car is 18.2% (rounded to the nearest tenth of a percent).
(b) To find the original cost of a car that has a yearly depreciation rate of 11% and is worth $10,000 after 2 years, we can use the same formula:

What is HCF?Highest Common Factor is the full name for HCF in mathematics.
According to the laws of mathematics, the highest positive integer that divides two or more positive integers without leaving a residual is known as the greatest common divisor, or gcd.
What is LCM?Least Common Multiple is the full name for LCM in mathematics.
LCM (a,b) in mathematics stands for the least common multiple, or LCM, of two numbers, such as a and b. The smallest or least positive integer that is divisible by both a and b is known as the LCM.
We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.
Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.
We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:
288 / x² = (16*18) / x² = 288 / x²
Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.
As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

What is area?A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.
To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.
The total area of the cake is:
16 inches x 18 inches = 288 square inches
To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:
√(288 square inches) ≈ 16.97 inches
Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:
Each piece of cake will be approximately 16 inches by 16 inches.
To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:
288 square inches ÷ (16 inches x 16 inches) = 18
Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.
