Answer:
difference in volume = 26.96h cm³
Step-by-step explanation:
The volume of a prism is the product of the base area and the height. A trapezoid prism has a trapezium as the base shape. Therefore,
volume of a trapezoid prism = area of a trapezium × height
area of the base(trapezoid) = 140 cm²
Volume = 140h
Volume of a cylinder = πr²h
where
r = radius
h = height
volume = πr²h
volume = π × 6² × h
volume = 3.14 × 36 × h
volume = 113.04h
To know how much larger the volume of the prism is than the volume of the cylinder we have to take the difference of the volume.
Recall the height are the same
difference in volume = 140h - 113.04h
difference in volume = 26.96h cm³
An airline claims that it rarely loses a passenger's checked luggage, and, if checked luggage is lost, 90% of the luggage is recovered and returned to the owner within 24 hours. A consumer group believes the 24-hour recovery rate of lost luggage is actually lower (worse) than the airline's claim. They surveyed a large random sample of the airline's customers and found that 103 of 122 people who had lost luggage were reunited with the missing items within 24 hours. Is this enough evidence to claim the proportion of people who lost luggage with this airline a

What is the distance from (−5, −19) to (−5, 32)? HELPP
13 units
51 units
−13 units
−51 units
The distance between the given coordinates (−5, −19) and (−5, 32) is given by 51 units.
Let us consider the coordinates of two given points be,
(x₁ , y₁ ) = ( -5 , -19 )
(x₂ , y₂ ) = (-5 , 32 )
Distance formula between two points is equals to,
Distance = √ ( y₂ - y₁)² + ( x₂ - x₁ )²
Substitute the values of the coordinates we have,
⇒ Distance = √ ( 32 - (-19))² + ( -5- (-5) )²
⇒ Distance = √ (32 +19)² + (-5 + 5)²
⇒ Distance = √ 51² + 0²
⇒ Distance = 51 units.
Therefore, the distance between the two points is equal to 51 units.

The speeds of the fastballs thrown by major league baseball pitchers were measured by radar gun. The mean speed was 87 miles per hour. The standard deviation of the speeds was 3 mph. Which of the following speeds would be classified as an outlier?
a. 84 mph b. 92 mph c. 97 mph d. 81 mph
Thus, the answer is option (c) 97 mph.
An outlier is a value that lies significantly away from the rest of the values in the dataset. For a given dataset, we can determine outliers using z-scores.According to the problem statement, the mean speed of the fastballs thrown by major league baseball pitchers is 87 mph, and the standard deviation is 3 mph. To determine which speed is an outlier, we need to find its corresponding z-score.z = (x - μ) / σHere, x is the speed we want to test, μ is the mean speed, and σ is the standard deviation of speeds.Using the formula above, we can calculate the z-scores for each speed given in the options:a. z = (84 - 87) / 3 = -1b. z = (92 - 87) / 3 = 1.67c. z = (97 - 87) / 3 = 3.33d. z = (81 - 87) / 3 = -2Since a z-score of ±2 or higher is generally considered an outlier, the speeds of 97 mph and 81 mph are classified as outliers. Thus, the answer is option (c) 97 mph.

The formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. Use this formula to estimate the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
Answer:
v = 200 m/s
Step-by-step explanation:
The formula for the speed of a tsunami in deep water is given by :
\(v=\sqrt{gh}\)
Here,
g is acceleration due to gravity
h is the depth of the ocean in meters.
We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
It means we need to find v if h = 4000 m
So,
\(v=\sqrt{10\times 4000}\\\\v=200\ m/s\)
So, the speed of the tsunami is 200 m/s.
asuming 14 people, 5 men and 9 women, how many ways can they sit in a circle such that every man is diametricaly opposite a woman
There are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
In this problem, we want to find the number of ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
Since every man must be diametrically opposite a woman, we can pair each man with one woman. There are 5 men and 9 women, so there are 5 pairs. We need to find the number of ways to seat these 5 pairs of people in a circle.
To do this, we can first seat one pair in any position. Then, we can seat the second pair anywhere but opposite the first pair. This gives us 11 positions for the second pair. Continuing in this way, we see that there are 11 * 6 * 5 * 4 * 3 = 7920 ways to seat the 5 pairs of people in a circle.
So, there are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

What is logarithmic equation?A logarithmic equation is an equation in which a variable appears inside a logarithmic function. In other words, it is an equation in which the unknown quantity appears in the argument of a logarithm.
Logarithmic equations are often used to solve problems involving exponential growth or decay, as well as in various areas of mathematics, science, engineering, and finance.
A general logarithmic equation can be written in the form:
\(log(base a)(x) = b\)
where a is the base of the logarithm, x is the unknown variable, and b is a constant.
To solve a logarithmic equation, you would typically use properties of logarithms to simplify the equation and isolate the variable. Then, you would use algebraic techniques to solve for the variable.
using the properties of logarithms, we can simplify the equation as follows:
log₂(4x²) - log₂(6x) = 2
log₂[(4x²)/(6x)] = 2
log₂(2x/3) = 2
Now we can rewrite the equation in exponential form:
2^2 = 2x/3
\(4 = 2x/3\)
Multiplying both sides by 3/2, we get:
\(x = 6/2 = 3\)
Therefore, the solution to the equation is x = 3.\(2^2 = 2x/3\)

A pizzeria uses a 3-pound bag of cheese to make 8 pizzas. Use the given ratio to compute the number of pizzas the pizzeria can make with each number of pounds of cheese.
Answer:
18 pounds = 48 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas
Step-by-step explanation:
1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)
2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)
3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)
The table is:
Cheese Number of Pizzas
3 pounds 8
18 pounds 48
22.5 pounds 60
27 pounds 72
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
3 pounds bag of cheese makes 8 pizzas.
This means,
3 pounds = 8 pizzas
1 pound = 8/3 pizzas
Now,
1 pound = 8/3 pizzas
Multiply 18 on both sides.
18 pounds = 18 x 8/3
18 pounds = 48 pizzas
1 pound = 8/3 pizzas
Multiply 22.5 on both sides.
22.5 pounds = 22.5 x 8/3
22.5 pounds = 60 pizzas
1 pound = 8/3 pizzas
Multiply 27 on both sides.
27 pounds = 27 x 8/3
27 pounds = 72 pizzas
Thus,
The number of Pizzas for 3 pounds is 8.
The number of Pizzas for 18 pounds is 48.
The number of Pizzas for 22.5 pounds is 60.
The number of Pizzas for 27 pounds is 71.

The solution to 4 is a>-162. This is because the inequality can be rewritten as -162 > -21, meaning that any number greater than -162 will satisfy the inequality.
What is inequality?Inequality is the unequal distribution of opportunities, resources, or rights among people or groups. It can be found in wealth, income, health, education, access to services and resources, and legal rights. Inequality is a social phenomenon that affects people differently depending on race, gender, age, or background. Inequality can be a result of unequal access to resources, differences in power dynamics, or the unequal distribution of resources among people or groups. It can lead to disparities in health, education, and economic outcomes for those who experience it. Inequality can be addressed through policies that promote equity and inclusion, such as targeted education initiatives and access to employment opportunities.
The reason this is happening is because when solving inequalities, we must isolate the variable on one side of the inequality sign. In this case, we can do this by adding 162 to both sides of the inequality. This will move the -21 to the other side and the result is a>-162.
In order to ensure that the solution is correct, it is important to check the answer by substituting a value larger than -162 into the inequality. If the value satisfies the inequality, then the solution is correct.

Find the volume of the solid bounded below by the circular cone z=1.5√x^2+y^2 and above by the sphere x^2+y^2+z^2=2.75
The volume of the solid bounded below by the circular cone z=1.5√(x^2+y^2) and above by the sphere x^2+y^2+z^2=2.75 is (1/6)π(2.75)^3 - (1/6)π(1.5)^3.
To find the volume, we need to determine the limits of integration. The cone equation suggests that we should integrate over the region defined by z=1.5√(x^2+y^2). The sphere equation defines the upper boundary.
Using spherical coordinates, we have the following limits:
ρ: from 0 to √2.75 (radius of the sphere)
θ: from 0 to 2π (full revolution)
φ: from 0 to π/3 (the cone angle)
The volume element in spherical coordinates is ρ^2sin(φ)dρdθdφ. Substituting the given equations into the volume element, we get (ρ^2sin(φ))(ρ^2sin(φ))dρdθdφ.
Integrating with respect to ρ first, we have ∫[0 to π/3] ∫[0 to 2π] ∫[0 to √2.75] (ρ^4sin^2(φ))dρdθdφ.
Simplifying further, we obtain ∫[0 to π/3] ∫[0 to 2π] (1/5)(√2.75)^5sin^2(φ)dθdφ.
Integrating with respect to θ, we have ∫[0 to π/3] (2π)(1/5)(√2.75)^5sin^2(φ)dφ.
Now integrating with respect to φ, we get (2π)(1/5)(√2.75)^5(φ - (1/2)sin(2φ)) evaluated from 0 to π/3.
Substituting the limits and simplifying, we find the volume of the solid to be (1/6)π(2.75)^3 - (1/6)π(1.5)^3.
