What is the volume of the Sphere ?
The volume of the Sphere is the capacity it has. It is the space occupied by the sphere.
Formula used to find volume of the Sphere is :
V = 4/3 × π × r^3
Given : diameter = 22 cm
r = diameter/2
r = 11 cm
So ,
V = 4/3 × π × 11 ^3
⇒ 4/3 × π × 1331
⇒ 1.34 × 4179.34
V = 5575.28 cm^3
The nearest cubic unit is 5,575 cm^3.
Hence , the volume of the Sphere is 5,575 cm^3 .

Answers
length of a line segment is 58 units.
Answer:
Option D, 58
Step-by-step explanation:
Line segment having end points are 19 and -39
So total length of line segments having end points of 19 and (-39) = distance from origin to one end at (19) + distance of another end from origin
= 19 + 39
= 58

Quadrilateral ABCD is similiar to quadrilateral EFGH The lengths of the three longest sides in quadrilateral ABCD are 24 feet, 16 feet, and 12 feet long. If the two shortest sides of quadrilateral EFGH are 9 feet long and 18 feet long, how long is the 2nd longest side on quadrilateral EFGH
?
Answers
They are similar, so the sides of one of them and the other one are in proportion.
We have to find the proportion. Notice that the 12 feet side and the 18 feet side must be the one in common. 3 longest ones ... one is missing, then, two shortest ones ... two are missing, but they must share that one:
The ratio is the 18:12 or 3:2.
Now we can complete both quadrilaterals:
ABCD: 24, 16, 12, ?
EFGH: ?, ?, 18, 9
ABCD: 24, 16, 12, 6
EFGH: 36, 24, 18, 9

The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds. Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points) Part B: Explain what the solution from Part A means in the context of the problem. (4 points) (10 points)
Answers
We are given the functions:
h(t) = -16t^2 + 60t + 95
g(t) = 20 + 38.7t
Part A. All we have to do is to plug in the value of t = 1 to 4 on the two functions
t h(t) g(t)
1 139 58.7
2 151 97.4
3 131 136.1
4 79 174.8
Looking at
the table, we can say that the time when h(t)=g(t) must be between t=2 and t= 3
seconds
At t=2 seconds h(t) is above g(t), and at t = 3 seconds h(t) is below g(t).
Therefore the two functions must be at the same height in between.
Part B. The solution in Part A gives us the exact time where the two objects have the same height. Further, we can see from the table that h(t) is decreasing meaning the projectile is going down while g(t) is increasing so the other projectile is going up.
The following graph describes function 1, and the equation below it describes function 2:
Function 1

Function 2
f(x) = −x2 + 2x − 15
Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)
Answers
Function 2 ⇒ [tex]- x^{2} +2x-15[/tex]
Both functions are shown in the graph below
As well as graphing, we can also find out the function with the highest maximum by using the formula to find the x-coordinate when the function is maximum/minimum
[tex]x=- \frac{b}{2a} [/tex]
Maximum vertex for function 1 is [tex]x=- \frac{8}{(2)(-1)} = \frac{-8}{-2} =4[/tex]
Maximum vertex for function 2 is [tex]x=- \frac{2}{(-2)(-1)}= \frac{-2}{-2}=1 [/tex]
Hence the function with the highest maximum is function 1
Answer:
The Function __1__ has the larger maximum.
Step-by-step explanation:
The given functions are
Function 1:
[tex]f(x)=-x^2+8x-15[/tex]
Function 2:
[tex]f(x)=-x^2+2x-15[/tex]
Both functions are downward parabola because the leading coefficient is negative. So, the vertex is the point of maxima.
If a function is [tex]f(x)=ax^2+bx+c[/tex], then its vertex is
[tex]Vertex=(\frac{-b}{2a}, f(\frac{-b}{2a}))[/tex]
The vertex of Function 1 is
[tex]Vertex=(\frac{-8}{2(-1)}, f(\frac{-8}{2(-1)}))[/tex]
[tex]Vertex=(4, f(4))[/tex]
The value of f(4) is
[tex]f(4)=-(4)^2+8(4)-15=1[/tex]
The vertex of Function 1 is (4,1). Therefore the maximum value of Function 1 is 1.
The vertex of Function 2 is
[tex]Vertex=(\frac{-2}{2(-1)}, f(\frac{-2}{2(-1)}))[/tex]
[tex]Vertex=(1, f(1))[/tex]
The value of f(1)is
[tex]f(1)=-(1)^2+2(1)-15=-14[/tex]
The vertex of Function 2 is (1,-14). Therefore the maximum value of Function 2 is -14.
Since 1>-14, therefore Function __1__ has the larger maximum.
All computers are on sale for 10% off the original price.

Answers
We are given the functions:
P (x) = 0.9 x
C (x) = x – 150
We can generate two composition functions from the given two functions in the form of:
P [C (x)] and C [P (x)]
Since the problem states that we are to find for the final price after a 10% discount is followed by a $150 coupon then we should find for:
C [P (x)]
The value of C [P (x)] can obtained by plugging in the value of P (x) into x in the equation of C (x), therefore:
C [P (x)] = [0.9 x] – 150
C [P (x)] = 0.9 x – 150 (ANSWER)

If the correlation between two variables is .496, how much of the variance has not been accounted for
Answers
If the correlation between two variables is .496, it has 24.6 percent (24.6%) of the variance that has not been accounted for. Hence, correlation is a statistical technique that is used to measure and describe the strength and direction of the relationship between two variables and 24.6% has not been accounted for the two variables which is .496.
Final answer:
About 75.40% of the variance between two variables with a correlation coefficient of .496 is unaccounted for, as it is the complement of the coefficient of determination (24.60%) obtained by squaring the correlation coefficient.
Explanation:
To determine the amount of variance not accounted for by the correlation between two variables with a correlation coefficient of .496, we must use the coefficient of determination. The coefficient of determination is the square of the correlation coefficient (r₂), which represents the proportion of the variance for the dependent variable that's explained by an independent variable in a regression model.
First, we calculate r₂:
.4962 = .246016, or approximately 24.60%. This means that about 24.60% of the variance in the dependent variable is explained by the independent variable.
Next, we find the unexplained variance by subtracting r₂ from 1:
1 - .246016 = .753984, or approximately 75.40%. Therefore, 75.40% of the variance has not been accounted for by the correlation.

3y = -2x + 2
y = -2/3x + 2/3...slope = -2/3, y int = 2/3
different slopes, different y int's....means 1 solution...so yes, they intersect
TRUE
Answer:
the given statement is true.
Step-by-step explanation:
The given lines are
2x - 3y = 1 and 2x + 3y = 2
Write these equations in slope intercept form of a line y = mx +b
For the first equation
[tex]2x-3y=1\\\\3y=2x-1\\\\y=\frac{2}{3}x-\frac{1}{3}[/tex]
For the first equation
[tex]2x+3y=2\\\\3y=-2x+2\\\\y=-\frac{2}{3}x+\frac{2}{3}[/tex]
The slope and y-intercepts of first line are 2/3 and -1/3 respectively.
The slope and y-intercepts of second line are -2/3 and 2/3 respectively.
Since, the slopes and y-intercepts of these lines are different.
Hence, these lines are intersecting.
Therefore, the given statement is true.

Urn A has balls numbered 1 through 6. Urn B has balls numbered 1 through 4. What is the probability that a 4 is drawn from A followed by a 2 from B?
Answers
This means that there are 6*4=24 possible outcomes, which could be listed as
{(1, 1), (1, 2), (1, 3), (1, 4), (2, 1)... (6, 3), (6, 4)},
where the first coordinates represent drawing from urn A, and the second coordinates, drawing from urn B.
(4, 2) is one of these 24, so the probability is 1/24
remark, this problem could also have been solved by the multiplication principle of the probabilities of separate events, that is 1/6 (probability of drawing 4 from Urn A) times 1/4 (probability of drawing 2 from B) = 1/24
Answer: 1/24
The probability that a 4 is drawn from A followed by a 2 from B is 1/24
Further explanationThe probability of an event is defined as the possibility of an event occurring against sample space.

Let us tackle the problem.
Urn A has balls numbered 1 through 6 → Total = 6 ballsThe probability of choosing a 4 ( 1 ball ) from Urn A is:
[tex]P(A) = \boxed{\frac{1}{6}}[/tex]
Urn B has balls numbered 1 through 4 → Total = 4 ballsThe probability of choosing a 2 ( 1 ball ) from Urn B is:
[tex]P(B) = \boxed {\frac{1}{4}}[/tex]
The probability that a 4 is drawn from A followed by a 2 from B is
[tex]P(A \cap B) = P(A) \times P(B)[/tex]
[tex]P(A \cap B) = \frac{1}{6} \times \frac{1}{4}[/tex]
[tex]P(A \cap B) = \boxed {\frac{1}{24}}[/tex]

The number 4.5 is 75 percent of the number 6.
The given number is 4.5 cm.
Let 75% of x is 4.5 cm.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here, 75% of x=4.5
[tex]\frac{75}{100} \times x=4.5[/tex]
[tex]\frac{75x}{100}=4.5[/tex]
