Answer:
8.604 in.
Step-by-step explanation:
We can use the formula for compound interest to find the height of domino #9:
A = P(1 + r)^n
where A is the final amount, P is the initial amount, r is the growth rate, and n is the number of compounding periods. In this case, P is the height of domino #0, r is 15% or 0.15, and n is 9 (since we want to find the height of domino #9).
Substituting the given values:
A = 3.00 in * (1 + 0.15)^9
Simplifying:
A = 3.00 in * 2.86797199
A ≈ 8.604 in
Therefore, the height of domino #9 is approximately 8.604 inches.

The rim of a basketball hoop is 10 feet high. When Chase stretches his hand, it is 88 inches high. How many feet does Chase have to jump to be able to touch the rim?
Chase has to jump 2.67 feet to touch the rim.
The rim of the basketball hoop is 10 feet high, which is equal to 120 inches .
Chase's hand can reach 88 inches high.
To find out how many feet Chase has to jump to touch the rim, we need to subtract his reach from the height of the rim:
120 inches (height of rim) - 88 inches (Chase's reach) = 32 inches
So Chase has to jump 32 inches to touch the rim. To convert this to feet, we can divide by the number of inches in a foot:
32 inches ÷ 12 inches/foot = 2.67 feet
Therefore, Chase has to jump 2.67 feet to touch the rim.

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 2 ft by 2 ft by 12.5 ft. If the container is entirely full and, on average, its contents weigh 0.22 pounds per cubic foot, find the total weight of the contents. Round your answer to the nearest pound if necessary.
Answer:
38.81 pounds
Step-by-step explanation:
Considering the definition of right rectangular prism and its volume, the total weight of the contents is 38.81 pounds.
Right rectangular prism
A right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.
Volume of right rectangular prism
To calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.
That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.
Volume of the container
In this case, you know that:
the dimensions of the container built are 7.5 ft by 11.5 ft by 3 ft.
the container is entirely full and, on average, its contents weigh 0.15 pounds per cubic foot.
So, the volume of the container is calculated as:
7.5 ft× 11.5 ft× 3 ft= 258.75 ft³
Then, the total weight of the contents is calculated as:
258.75 ft³× 0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds
Finally, the total weight of the contents is 38.81 pounds.

find f(g(4)) and g(f(4)) given f(x)=2x-3 and g(x)=5x^2-4x+1
Answer:
g(f(4)) = 106.
Step-by-step explanation:
To find f(g(4)), we first need to find
g(4):g(4) = 5(4)^2 - 4(4) + 1 = 80 - 16 + 1 = 65
Now that we know g(4) is 65, we can find
f(g(4)):f(g(4)) = f(65) = 2(65) - 3 = 127
Therefore,
f(g(4)) = 127.
To find g(f(4)), we first need to find f(4):f(4) = 2(4) - 3 = 5
Now that we know f(4) is 5, we can find g(f(4)):
g(f(4)) = g(5) = 5(5)^2 - 4(5) + 1 = 125 - 20 + 1 = 106
Therefore, g(f(4)) = 106.

A bag contains 3 black balls, 2 blue balls, and 3 green balls. A
random sample of 4 balls is selected. Given that x is the number of
black balls. y is the number of blue balls.
a) Find the joint probability function f(x, y)
b) Find the joint probability distribution of f(x, y)
The requreid, the joint probability function f(x, y) is:
f(0,0) = 3/14
f(0,1) = 9/28
f(0,2) = 3/28
f(1,0) = 9/28
f(1,1) = 9/28
f(2,0) = 3/14
f(2,1) = 3/14
f(3,0) = 1/14
To evaluate the joint probability function f(x, y), we need to determine the probability of selecting x black balls and y blue balls out of a sample of 4 balls. We can do this using the hypergeometric probability distribution formula:
f(x,y) = P(X = x, Y = y) = (C(3, x) * C(2, y) * C(3, 4-x-y)) / C(8, 4)
where C(n, k) represents the number of combinations of k items chosen from a set of n items.
Plugging in the values, we get:
f(0,0) = (C(3,0) * C(2,0) * C(3,4-0-0)) / C(8,4) = 3/14
f(0,1) = (C(3,0) * C(2,1) * C(3,4-0-1)) / C(8,4) = 9/28
f(0,2) = (C(3,0) * C(2,2) * C(3,4-0-2)) / C(8,4) = 3/28
f(1,0) = (C(3,1) * C(2,0) * C(3,4-1-0)) / C(8,4) = 9/28
f(1,1) = (C(3,1) * C(2,1) * C(3,4-1-1)) / C(8,4) = 9/28
f(2,0) = (C(3,2) * C(2,0) * C(3,4-2-0)) / C(8,4) = 3/14
f(2,1) = (C(3,2) * C(2,1) * C(3,4-2-1)) / C(8,4) = 3/14

Case 3: p = 42 mi, A = 52.5 mi²
Case 4: p = 56.5 in, A = 179.424 in²
How to determine the perimeter and the area of a figure
In this problem we need to determine the perimeter and the area of four composite figures, that is, figures formed by combining triangles and rectangles, whose area formulas are listed below:
Triangle
A = 0.5 · b · h
Rectangle
A = b · h
Where:
A - Areab - Baseh - HeightNow we find the perimeter and the area of each figure:
Case 1
p = 2 · (18.8 cm) + 2 · (20 cm)
p = 77.6 cm
A = (15.2 cm) · (20 cm)
A = 304 cm²
Case 2
p = 10 ft + 8.1 ft + 7 ft
p = 25.1 ft
A = 0.5 · (10 ft) · (5.6 ft)
A = 28 ft²
Case 3
p = 17.5 mi + 6 mi + 18.5 mi
p = 42 mi
A = 0.5 · (17.5 mi) · (6 mi)
A = 52.5 mi²

9. The prices of sweat shirts at five different stores are $6, $12, $11, $15, and $18. The mean price is $12.40 and the median price is $12. Identify the outlier and describe how the mean and median for this data set are affected by it.
The outlier in this data set is the sweatshirt priced at $18 since it is significantly higher than the rest of the prices.
How does the outlier affect the mean and median for the data set?The mean is affected more by outliers than the median.
In the provided data, the mean is higher than the median, which suggests that there may be an outlier pulling the average up. The outlier value of $18 is causing the mean to be higher.
If we remove the outlier value of $18, the mean price would be (6+12+11+15)/4 = $11, which is lower than the original mean of $12.40.
On the other hand, the median would remain the same since it is not affected by extreme values.

The length BC of the bisected line segment is: 11.5
What is the length of the line after bisection?Usually a line that bisects a segment usually divides that segment into two equal parts.
Now, we are told that DE bisects Line AC at point B where AB = 3a + 4.
Thus, from the idea of a bisected segment, we can easily say that:
2(3a + 4) = a + 23
6a + 8 = a + 23
6a - a = 23 - 8
6a = 15
a = 15/6
a = 5/2
a = 2.5

To find the total number of people sitting in the full rows, Mandy multiplied 142 by 10 and 142 by 2 and then added the products. Does Mandy’s method make sense? Use what you know about multiplication to explain why or why not.
Mandy's solution makes sense since it entails multiplying the total number of persons in those entire rows (142) by the number of people in each row (ten).
How does multiplication apply?Similarly, multiplying the total number of people in the remaining seats (142) by the number of people in each row (2) yields the total number of people in the remaining seats. The total number of persons in the theater is calculated by adding these two components.
This is a viable use of multiplication's distributive property, in which we break down a multiplication issue into simpler products and then add them up. As a result, Mandy's approach is a viable method for determining the total number of people in the theater.

The principal amount was £1260, and the annual interest rate is 5.5%.
Given that, Olivia gets £1606.50 and £1675.80 after 5 years and 6 years of investment in simple interest respectively.
SI = principal × rate × time / 100
So,
P + 5pr = £1606.50
P = £1606.50 - 5pr............(i)
P + 6pr = £1675.80
P = £1675.80 - 6pr.........(ii)
Therefore,
£1606.50 - 5pr = £1675.80 - 6pr
Pr = 69.3
Put the value of pr in eq(i)
P + 5(69.3) = 1606.50
P = 1606.5 - 346.5
P = 1260

The least squares regression line was found. Using technology, it was determined that the total sum of squares (SST) was 11654 and the sum of squares of regression (SSR) was 11405.0.
The value of R² (coefficient of determination) is 0.0214
We know that the formula for the coefficient of determination is,
R² = 1 - (SSR / SST)
where, R² is the coefficient of determination
SST is the total sum of squares
SSR is the sum of squares of regression
Here, the total sum of squares (SST) = 11654
and the sum of squares of regression (SSR) = 11405
Using above formula,
R² = 1 - (SSR / SST)
R² = 1 - (11405 / 11654 )
