Answer:
V = 260.2 m^3
Step-by-step explanation:
The area of the circular base is (pi)(r)^2, where r is the radius and half the diameter.
In this case the volume of the cone is V = (1/3)(pi)(5 m)^2*(10 m) = 260.2 m^3
Answer: 262
...........................
The edge of a cube has length 10 inches with a possible error of 1%. The possible error, in cubic inches, in the volume of the cube is: a) 3 b) 1 c) 10 d) 30 e) all of these
Answer:
d) 30
Step-by-step explanation:
1% of 10 inch is 0.1 inch
10 inch + 0.1 inch = 10.1 inch
10 inch - 0.1 inch = 9.9 inch
V = s³
For s = 9.9 in., V = (9.9 in.)³ = 970.299 in.³
For s = 10.1 in., V = (10.1 in.)³ = 1030.301 in.³
For 10 in., V = (10 in.)³ = 1000 in.³
|1000 in.³ - 970.299 in.³| = 29.701 in.³
|1000 in.³ - 1030.301 in.³| = 30.301 in.³
The error is 30 in.³.

A research company is claiming that 75% of college students shop online. Jamila takes a sample of 200 college students and finds that 120 college students shop online. Which type of inference test should Jamila use?
a) Chi-squared test for homogeneity
b) Two-way ANOVA O
c) One-sample t-test
d) One proportion z-test
To determine which type of inference test to use in this situation, Jamila needs to consider the following:
The research question: In this case, the research question is whether the proportion of college students who shop online is significantly different from the proportion claimed by the research company (75%).
The type of data: Jamila has collected data on a sample of college students, rather than the entire population.
The type of variables: The variable of interest is a binary variable (students either do or do not shop online), and the proportion of students who shop online is being compared to a fixed value (75%).
Given this information, the appropriate test to use is a one proportion z-test. The one proportion z-test is a statistical test that is used to determine whether the proportion of a binary variable in a sample is significantly different from a known proportion in the population.

Step-by-step explanation:
when defined like this, we remember that when the right-angled triangular is inscribed into a circle, sine of an angle is the length of the opposite side of the angle divided by the radius. while cosine of the same angle is the adjacent side divided by the radius.
so, sin(angle) = 12/13 makes us imagine a circle of radius 13, and the side (or leg) opposite of the angle is 12.
now, Pythagoras tells us
c² = a² + b²
c being the Hypotenuse (which is the radius in our scenario), a and b are the legs.
13² = 12² + second leg²
169 = 144 + second leg²
second leg² = 25
second leg = 5
so,
cos(theta) = 5/13
tan(theta) = sin(theta) / cos(theta) =
= 12/13 / 5/13 = (12×13)/(5×13) = 12/5
sin²(theta) + cos²(theta) = (12/13)² + (5/13)² =
= 144/169 + 25/169 =
= 169/169 = 1
sec²(theta) - tan²(theta) =
= (1/cos(theta))² - (12/5)² =
= (1 / 5/13)² - 144/25 = (13/5)² - 144/25 =
= 169/25 - 144/25 = 25/25 = 1
The diagram below shows a cylinder with diameter 6 cm and height 20 cm. The
Volume, in cm³, of the cylinder is

The volume of the cylinder is 180π cm³.
What is volume ?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Volume is a measurement of three-dimensional space that is occupied. Numerous imperial or US customary units, as well as SI-derived units (such the cubic meter and liter), are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship.
As diameter = 6cm
We know that radius is half of diameter
∴ radius = 3 cm
height = 20 cm
Volume = π r² h
= π (3)²×20
= π × 9 × 20

Jerry flew a total of 4,320 miles over 3 months.
• He flew 6 flights each month.
• He flew the same distance each flight.
How many miles was each of Jerry’s flights?
The number of miles was each of Jerry’s flights travel is 240 miles.
Explain distance in miles.A mile is characterized as the unit of length, which is precisely equivalent to 5280 feet, or 1760 yards, and normalized as precisely 1609.344 meters by the Peaceful accord in 1959. The biggest unit is generally used to quantify the distance between places that are not even close to one another.
According to question:Jerry flew 6 flights each month.
Total flights in 3 months = 3(6) = 18 flights
Let distance traveled in each flight be x
Then,
18x = 4320 miles
x = 4320/18
x = 240 miles
Thus, each flight flow 240 miles.

when the admission price for a conference is $400, 1000 people will attend. for each $5 reduction in price, an additional 20 peopel will attend. let x be the number of 5 dollar reductions. determine the number of people that will attend as a function of x.
Let y be the number of people that will attend the conference as a function of x. The given information tells us that when x = 0 (the admission price is $400), y = 1000. Additionally, for each $5 reduction in price, an additional 20 people will attend.
We can express this relationship as a function as follows:
y = 1000 + 20xThis function tells us that the number of people that will attend the conference is equal to 1000, plus an additional 20 people for each $5 reduction in price (represented by the variable x).
For example, if the admission price is reduced by $10 (x = 2), the number of people that will attend the conference is given by:
y = 1000 + 20(2)
y = 1000 + 40
y = 1040
So, if the admission price is reduced by $10, 1040 people will attend the conference.

A researcher wishes to test whether two nominal variables with two and three respective categories are statistically independent. She observes a chi square value from Pearson's chi square test of independence of 10.00430. Consider the following propositions: PROPOSITION ONE: At the 5% significance level the appropriate decision could be a Type II Error; PROPOSITION TWO: At the 1% significance level the appropriate decision could be a Type II Error.
A. Proposition I is true and Proposition II is true
B. Proposition I is true and Proposition II is false
C. Proposition I is false and Proposition II is true
D. Proposition I is false and Proposition II is false
E. None of the above
The correct answer is Option A: Proposition I is true and Proposition II is true.
A researcher can use Pearson's chi square test of independence to determine if two nominal variables are independent or not. In this case, the researcher observed a chi-square value of 10.00430.
To determine whether the null hypothesis should be accepted or rejected, the researcher must compare the chi-square value to a critical value associated with the desired level of significance.
At the 5% significance level, the critical value is usually around 7.815, and at the 1% significance level, the critical value is usually around 10.827. Since the observed chi-square value (10.00430) is higher than the critical values for both the 5% and 1% significance levels, the appropriate decision could be a Type II Error for both levels of significance.
In other words, Proposition I (At the 5% significance level the appropriate decision could be a Type II Error) and Proposition II (At the 1% significance level the appropriate decision could be a Type II Error) are both true.

Step-by-step explanation:
You want to know the distance XY between tangent points on a segment tangent to two circles that are externally tangent to each other. The circles have radii 18 m and 32 m.
Pythagorean theoremAs shown in the attachment, a segment parallel to XY joining segments PX and QY can form a right triangle whose hypotenuse is the sum of the radii, and whose short leg is the difference of the two radii. The length of XY is the unknown leg of the right triangle, and can be found using the Pythagorean theorem.
a² +b² = c²
14² +b² = 50²
b² = 50² -14² = 2304
b = √2304 = 48
The length of XY is 48 meters.

Use the following information to answer the questions.
A. Citizens in each state were counted as three-fifths of a person.
B. Enslaved persons in each state were counted as three-fifths of a person.
C. Only three-fifths of the citizens in each state were eligible to vote in elections.
D. Only three-fifths of enslaved peoples in each state were eligible to vote in elections.
The way that the Three-Fifths Compromise affected the 1790 census results was B. Enslaved persons in each state were counted as three-fifths of a person.
What was the Three - Fifths Compromise ?A settlement known as the "three-fifths compromise" was reached at the 1787 Constitutional Convention and permitted Southern states to count some of their enslaved population as three-fifths of a person for taxes and representational purposes. This first happened in the 1790 census results.
Many of the Founding Fathers recognized that slavery went against the ideal of liberty that was at the heart of the American Revolution, but they were unable to act decisively to end it because they were dedicated to the sanctity of private property rights, the ideas of limited government, and the pursuit of intersectional harmony.

Given the function f(x) = −5x2 + 2x + 9, find f(1) and f(2). Choose the statement that is true concerning these two values
We can solve the question using the concept Polynomial functions. The value of f(1) is 6 and f(2) is -7.
What do you mean by Polynomial function?In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1. A function that can be expressed as a polynomial is referred to as a polynomial function. A polynomial equation's definition can be used to derive the definition. A polynomial is typically denoted by P. (x). The degree of the variable in P(x) is its maximum power. The degree of a polynomial function is crucial because it reveals how the function P(x) will behave when x is very large. Whole real numbers make up a polynomial function's domain (R).
CalculationGiven f(x)=-5x2 + 2x + 9
f(1)=-5(1)2+2(1)+9
∴f(1)=6
f(2)=-5(2)2+2(2)+9
∴f(2)=-7

In the diagram, transversal t cuts parallel lines a and b. Which equation is necessarily true?
OA. m/1=m/7
OB.
O C.
O D.
m23=m26
m25+ m28 = 90°
m26+ m27 = 180°
Answer:
A. ∠1 = ∠7
B. ∠2 = ∠6
D. ∠6 + ∠7 = 180°
Step-by-step explanation:
⭐ Why A is correct
∠1 = ∠7 because when two parallel lines are cut by a transversal, alternate exterior angles are formed. Alternate exterior angles are congruent.∠1 and ∠7 are alternate exterior angles.Therefore, ∠1 = ∠7.⭐ Why B is correct
∠2 = ∠6 because when two parallel lines are cut by a transversal, corresponding angles are formed. Corresponding angles are congruent.∠2 and ∠6 are corresponding angles.Therefore, ∠2 = ∠6.❌ Why C is incorrect
∠5 + ∠8 is not equal to 90° because ∠5 and ∠8 are adjacent angles.Adjacent angles sum to 180°.Therefore, ∠5 + ∠8 is not equal to 90°.⭐ Why D is correct
∠6 + ∠7 = 180° because ∠6 and ∠7 are adjacent angles.Adjacent angles sum to 180°.Therefore, ∠6 + ∠7 = 180°.
