A cone and cylinder have the same height and their bases are congruent circles. If the
volume of the cylinder is 120 in3, what is the volume of the cone?
Answer:
40 in³
Step-by-step explanation:
You want the volume of a cone if the volume of a cylinder with the same radius and height is 120 in³.
FormulasThe formulas for the volume of a cylinder and cone are ...
V = πr²h . . . . . volume of a cylinder with radius r and height h
V = 1/3πr²h . . . . . volume of a cone with radius r and height h
Cone volumeIf the volume of the cylinder is such that ...
πr²h = 120 in³,
we can substitute for πr²h in the formula for the volume of the cone:
V = 1/3πr²h = 1/3(120 in³) = 40 in³
The volume of the cone is 40 in³.

Question:
Some smells are perceived as being more feminine or more masculine. Researchers asked a random sample of 300 American adults to score quantitatively the perceived gender-orientation of lavender. Smaller scores indicate a more feminine scent and larger scores a more masculine scent. In this design, a gender-neutral scent would have a perceived gender-orientation score of 12. The participants gave the scent of lavender an average score of 10.28.
Is this evidence that the scent of lavender is not gender neutral, on average? Select the correct statement of H0, Ha, and the hypotheses parameter in the corresponding test. -
a) Let µ be the mean gender-orientation score for all smells being studied. We test H0: µ=12 versus Ha: µ≠12 ; The alternative is two-sided because we want to test if all of the smells are not gender-neutral.
b) Let µ be the mean gender-orientation score for lavender. We test H0:µ=1.28 versus Ha:µ≠10.28; The alternative is two-sided because we want to test if lavender is not gender-neutral.
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.
d) Let µ be the mean gender-orientation score for lavender. We test H0: µ < 12 versus Ha: ≥ 12 ; The alternative is not two-sided because we want to test if lavender is gender-neutral.
Answer:
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.
Step-by-step explanation:
Here, some smells are perceived to be more feminine while some are more masculine. The researcher picked a sample size of 300 american adults to score quantitatively the perceived gender-orientation of lavender.
We are told that when the score is smaller it indicates a mord feminine scent, when the score is larger it indicates a more masculine scent while a score of 12 indicates a gender neutral scent.
In this case the participants gave lavender a score of 10.28
From the above information we have the following :
Mean, µ = 12
Sample size = 300
Sample mean x' = 10.28
Since the sample mean is less than 12, the null and alternative hypotheses will be:
H0 : µ = 12
Ha : µ ≠ 12
This is a two tailed test because the alternative hypothesis is not gender based, which means lavender could be perceived to be either more feminine or more masculine.
The correct option is option C.
c) Let µ be the mean gender-orientation score for lavender. We test H0: µ=12 versus Ha: µ≠12; The alternative is two-sided because we want to test if lavender is not gender-neutral.

There is a rectangular prism with a length of 12.5 in., a width of 11 in. and a height of 4 in. If you make a horizontal slice through it, what is the area of the exposed 2-dimensional shape? (show your work in numbers)
Answer: The required area of the exposed 2-dimensional shape would be 137.5 sq. inches.
Step-by-step explanation:
Given, There is a rectangular prism with a length of 12.5 in., a width of 11 in. and a height of 4 in.
If we make a horizontal slice through it, then we will have two-dimensional figure called 'rectangle' with dimensions length by width as 12.5 in. by 11 in. [As per given]
Then, the area of the exposed 2-dimensional shape = Area of the reactngle
= Length x width
[tex]=12.5\text{ in.}\times11\text{ in.}\\\\=137.5\text{ in.}^2[/tex]
Hence, the required area of the exposed 2-dimensional shape would be 137.5 sq. inches.

Answer:
B
Step-by-step explanation:
For example let's set up a quadratic equation.
Let's use
f(x) = (x + 10)^2 + 7
The seven is the y intercept so let's ignore that and focus on the ten.
When we graph this we end up getting the picture below. Now, why is the vertex at -10? The reason is the equation starts off with a negative sign.
f(n) = (h - x) + k
So, if x is positive then it will remain negative but still go in positive just because the equation has a subtraction sign in it.
As a result when the equation has + 10, it shows that the x is negative because x = -10 and when you do
h- (-10) it becomes h + 10.

Answer: They are similar because they intersect with each other at (-1,3).
Which equation represents the following graph y=3x+2
For this equation you simply have to graph it.
First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.
Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.
Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

Use the table to answer the questions that follow,
Calculate the product moment correlation coefficient for the data and interpret your result.
(3 Marks)
Answer:
r=0.96
Step-by-step explanation:
The Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that shows the strength of the linear relationship between two variables.
Given the result of 10 hospital patients which were sampled below:
[tex]\left|\begin{array}{c|ccccccccccccc}$Patient&A&B&C&D&E&F&G&H&I&J\\$Age (X) in Years&20&25&50&30&45&60&10&15&35&70\\$B.P.(Y) in mmHg&80&85&125&90&100&135&80&70&100&140\end{array}\right|[/tex]
To determine the product moment correlation coefficient for the data, we follow the steps below:
Step 1: Find the following as it was done in the table below.
[tex]\sum{X}~,~ \sum{Y} ~,~ \sum{X \cdot Y} ~,~ \sum{X^2}~,~and \sum{Y^2}[/tex]
Step 2: Take the sum of every column to obtain:
[tex]\sum{X}=360 ~,~ \sum{Y}=1005 ~,~ \sum{X \cdot Y}=40425 ~,\\~ \sum{X^2}=16500 ~,~ \sum{Y^2}=106475[/tex]
Step 3: Use the following formula to find the PMCC.
[tex]r=\dfrac{n\cdot\sum{XY} - \sum{X}\cdot\sum{Y}}{\sqrt{\left[n \sum{X^2}-\left(\sum{X}\right)^2\right] \cdot \left[n \sum{Y^2}-\left(\sum{Y}\right)^2\right]}}[/tex]
[tex]=\dfrac{10\cdot 40425 - 360\cdot1005}{\sqrt{\left[10*16500}-\left(360\right)^2\right] \cdot \left[10*106475-\left(1005\right)^2\right]}}[/tex]
[tex]=\dfrac{42450}{\sqrt{1937265000}}\\=0.9645\\r\approx 0.96$ (correct to 2 decimal places)[/tex]
Interpretation
When r is closer to 1, there is a strong positive relationship between the variables. A value of 0 indicates that there is no relationship between the variables. Values close to -1 signal a strong negative relationship between the two variables.Since r=0.96 which is closer to 1, we conclude that there is a strong relationship between the age and the high blood pressure related deaths in the state.

q=7-3p ------------------(1a)
2p- 2q= -6 -------------(2)
Substitute (1a) in (2)
We have :
2p - 2( 7- 3p) = -6
2p -14 + 6p = -6
8p= 14-6= 8
P= 8/8 =1

Equation of the circle has been given as x² + 12y + 22x + y²- 167 = 0
Now we will convert this equation into the standard equation of the circle.
x² + 12y + 22x + y² - 167 = 0
(x² + 22x) + (y² + 12y) = 167
[x² + 2(11)x] + [y² + 2(6y)] = 167
[x² + 2(11)x + (11)²- (11)²] + [y² + 2(6)y + (6)²- (6)²] = 167
[x² + 1(11)x + (11)²] - (11)² +[y² + 2(6)y + 6²] - (6)² = 167
(x + 11)² + (y + 6)²- (11)²- (6)² = 167
(x + 11)² + (y + 6)² - 121 - 36 = 167
(x + 11)² + (y + 6)² - 157 = 167
(x + 11)² + (y + 6)²- 157 + 157 = 167 + 157
(x + 11)² + (y + 6)² = 324
Therefore, option (2) will be the standard equation of the given circle.

Answer:
546.208
Step-by-step explanation:
Let's break this down.
5 x 100 = 500
4 x 10 = 40
6 x 1 = 6
2 x 1/10 = .2
8 x 1/1000 = .008
Now, let's add to find the number.
500 + 40 + 6 + .2 + .008 = 546.208
Therefore, the number in standard form is 546.208
The final answer of Mrs. bell expression will be 546.208
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
the expanded form of a number is written as :
5 x 100 + 4 x 10 + 6 x 1 + 2 x 1/10 + 8 x 1/1000
Let's calculate it bit by bit :
[tex]\begin{aligned}5 \cdot 100 = 500\\4 \cdot10 = 40\\6 \cdot 1 = 6\\2 \cdot \frac{1}{10} = .2\\8 \cdot \frac{1}{1000} = .008\\\end{aligned}[/tex]
Now, let's add all the terms we get :
500 + 40 + 6 + .2 + .008 = 546.208
Therefore, the number in standard form of expression written by Mrs. bell is 546.208

Write the equation of a line with the slope of 2, which contains the point
(4,-8).
Write your equation in slope intercept form and do NOT put any spaces in your answer.
Answer:
y=2x-16
Step-by-step explanation:
So since we have a point and the slope, we can use the point-slope equation to find our equation of a line
y - y₁ = m(x - x₁)
Here our (x₁, y₁) point is (4, -8) and our m is 2
Plugging in these values to our equation gives us:
y - (-8) = 2(x - (4)) → distributing the negative to the -8 gives y + 8 = 2(x - 4) → distributing the 2 to the (x - 4) gives y + 8 = 2x - 8 → and finally subtracting the 8 from both sides gives our equation of a line y = 2x - 16
