Consider the given data set consisting of the number of texts sent by students during lunch.
0, 2, 3, 5, 5, 7, 8, 8, 8, 8, 9,9.9,9,10,10, 10, 10, 10, 11, 11, 11, 11, 11, 12, 12. 12. 12. 12, 12
The mean for this data set is 8.9 and the median is 10.
One student texted 48 times during lunch and we added her data point to the original data
set so that it now looks like this:
0, 2, 3, 5, 5, 7, 8, 8, 8, 8, 9,9,9,9,10,10, 10, 10, 10, 11, 11, 1111, 11, 12, 12. 12, 12, 12, 12, 48
What measure of center will be most affected by the new data point?
The mean will be most affected.
Answer:
The mean.
Step-by-step explanation:
48 messages is a very high compared to the rest of the data so it will effect the mean. The median and the mode will be unchanged and the IQR will only change slightly. The mean will change form 8.9 to 10.2.

Through which points should a line of rotation be placed to create a cylinder with a radius of 3 units?
E and J
F and I
J and G
G and E
My answer:
From the photo, we can see that:
the point F is in the middle of the length EG => EF = FG = 3 units
the point I is in the middle of the length JH and because this is a rectangle so EG = JH
=> JI = JH = 3 units
So the points should a line of rotation be placed to create a cylinder with a radius of 3 units is: F and I where F and I are the center points of the two bases in the cylinder

a. 2x + 3y = 17 and 3y = 15 - x
Answer:
(2, [tex]\frac{13}{3}[/tex] )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 17 → (1)
3y = 15 - x → (2)
Substitute 3y = 15 - x into (1)
2x + 15 - x = 17, that is
x + 15 = 17 ( subtract 15 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting in (1)
2(2) + 3y = 17
4 + 3y = 17 ( subtract 4 from both sides )
3y = 13 ( divide both sides by 3 )
y = [tex]\frac{13}{3}[/tex]
Solution is (2, [tex]\frac{13}{3}[/tex] )
Rearranging...
3y + x = 15
3y + 2x = 17
Using elimination method
2x - x = -15 + 17
X = 2
From equation.... 2
3y + 2 = 15
3y = 15 - 2
3y = 13
Y = 13/3
::x = 2 while y = 13/3

Identify whether each value of x is a discontinuity of the function by typing asymptote, hole, or neither.
5x
x3 + 5x2 + 6x
x= -3
x = -2
x=0
x = 2
x= 3
x=5
DONE
Answer:
nobody gave the right answers but here it is :
Step-by-step explanation:
x = −3
⇒ asymptote
x = −2
⇒ asymptote
x = 0
⇒ hole
x = 2
⇒ neither
x = 3
⇒ neither
x = 5
⇒ neither
To determine whether each value of x is a discontinuity of the function, we analyze the function to find asymptotes or holes. For the given function, x = -2 and x = -3 are asymptotes, x = 0 is a hole, and the remaining values of x do not create any discontinuities.
Explanation:To determine whether each value of x is a discontinuity of the function, we need to analyze the function and look for asymptotes or holes. Let's consider the function f(x) = (5x) / (x^3 + 5x^2 + 6x).
To identify asymptotes, we need to find the values of x where the denominator of the function is equal to zero. For x = -2 and x = -3, the denominator becomes zero, which indicates that there are vertical asymptotes at x = -2 and x = -3. These values are neither holes nor asymptotes.
For x = 0, the denominator also becomes zero, but the numerator is not zero. This indicates that there is a hole at x = 0.
For the remaining values of x (2, 3, and 5), neither the numerator nor the denominator becomes zero. Therefore, these values do not create either holes or asymptotes. So the answer is:
x = -3: asymptotex = -2: asymptotex = 0: holex = 2: neitherx = 3: neitherx = 5: neitherIf h = 18 units and r = 8 units, then what is the volume of the cone shown above? A. B. C. D.
1,205.76 units^3 or 384 π
Here is why:
The formula for the volume of a cone is:
[tex]V=\frac{1}{3}\pi r^2 h[/tex]
We can plug in.
[tex]V=\frac{1}{3}*3.14*8*8*18[/tex]
= 1,205.76 units^3

T-shirts at Perfect Tee cost either $9 or
$10 depending on the style. Bella bought
13 t-shirts for a total of $124. How many
t-shirts of each price did she buy?
Answer:
Bella bought the t-shirt at $9.54 each.
Step-by-step explanation:
We are given the following in the question:
"T-shirts at Perfect Tee cost either $9 or $10 depending on the style."
Cost of 13 t-shirts = $124
We have to find the cost of each t-shirt.
Cost of 1 t-shirt =
[tex]=\dfrac{\text{Total cost of t-shirts}}{\text{Number of t-shirts}}\\\\=\dfrac{\$124}{13}\\\\=\$9.5384\approx \$9.54[/tex]
Thus, Bella bought the t-shirt at $9.54 each.
a cylindrical bucket has a radius of 6 inches and a height of 18 inches. What is the minimum number of buckets of water needed to completely fill a spherical storage tank that has a radius of 15 inches?
Answer:
Minimum 7 buckets of water is needed to completely fill spherical storage tank.
Step-by-step explanation:
We are given the following in the question:
Cylindrical bucket:
Radius, r = 6 inches
Height = 18 inches
Volume of bucket = Volume of cylinder
[tex]V = \pir^2 h \\V = 3.14\times (6)^2\times 18\\V =2034.72\text{ cubic inches}[/tex]
Spherical storage tank:
Radius, r = 15 inches
Volume of tank = Volume of sphere =
[tex]V =\dfrac{4}{3}\pi r^3\\\\\V = \dfrac{4}{3}\times 3.14\times (15)^3\\\\V = 14130\text{ cubic inches}[/tex]
Number of baskets required =
[tex]n = \dfrac{\text{Volume of tank}}{\text{Volume of bucket}}\\\\n =\dfrac{14130}{2034.72} = 6.94 \approx 7[/tex]
Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.

There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located. The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.The slope, the change in y divided by the change in x for two points, is ...... (-1 -2)/(10 -5) = -3/5This is the slope and the coefficient of x in the linear equation.Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:... y = mx + b... y = (-3/5)x + 5

13) If the area of your simming poolis 25
times larger than your neighbors, how
many times larger is your pool compared to
theirs? What is the sale factor?)
Answer:
1. 25 times larger
2. The scale factor is 25:1
Step-by-step explanation:
Given
Let A represent the area of your swimming pool
Let a represents the area of your neighbour's swimming pool.
From the question, we understand that the area of your swimming pool is 25 times larger than the area of you neighbour's. This can be represented as follows;
A = 25 * a. --- divide through by a
A/a = 25 * a/a
A/a = 25
This means that your pool is 25 times larger than your neighbour's.
To get the scale factor, we have to convert the expression above to ratio
A/a = 25
This can be rewritten as
A/a = 25/1
By comparison the position of constraints at the left hand side to those at the right hand side of the equation
A = 25
a = 1
So,
A : a = 25 : 1
Hence, the scale factor is 25 : 1
I own a large truck, and my neighbor owns four small trucks that are all identical. My truck can carry a load of at least $600$ pounds more than each of her trucks, but no more than $\frac{1}{3}$ of the total load her four trucks combined can carry. Based on these facts, what is the greatest load I can be sure that my large truck can carry, in pounds?
Answer:
there is no greatest load
Step-by-step explanation:
Let x and y represent the load capacities of my truck and my neighbor's truck, respectively. We are given two relations:
x ≥ y +600 . . . . . my truck can carry at least 600 pounds more
x ≤ (1/3)(4y) . . . . . my truck carries no more than all 4 of hers
Combining these two inequalities, we have ...
4/3y ≥ x ≥ y +600
1/3y ≥ 600 . . . . . . . subtract y
y ≥ 1800 . . . . . . . . multiply by 3
My truck's capacity is greater than 1800 +600 = 2400 pounds. This is a lower limit. The question asks for an upper limit. The given conditions do not place any upper limit on truck capacity.
Answer:
[tex]\large \boxed{\text{2400 lb}}[/tex]
Step-by-step explanation:
We have two condition:
Let x = the load of your truck
and y = load of their trucks Then
(1) x ≥ y + 600
4y = the total load of their four trucks
⅓ × 4y = the load of load of your truck
(2) ⁴/₃x ≤ y
Calculations:
[tex]\begin{array}{lrcll}(1) & x & = & y+ 600\\(2)& x & =&\dfrac{4}{3}y\\\\(3)& x - 600 & =&y&\text{Subtracted 600 from each side of (1)}\\& x & = & \dfrac{4}{3}(x - 600)&\text{Substituted (3) into (2)}\\\\&3x & = & 4(x - 600)&\text{Multiplied each side by 3}\\\end{array}[/tex]
[tex]\begin{array}{lrcll}&3x & = & 4x - 2400&\text{Distributed the 4}\\&3x + 2400 & = & 4x&\text{Added 2400 to each side}\\ & x & = & \mathbf{2400}&\text{Subtracted 3x from each side}\\\end{array}\\\text{The greatest load my truck can carry is $\large \boxed{\textbf{2400 lb}}$}}[/tex]

Describe the sorting rule for the numbers in these two groups
Group A;0,1,4,5,8
Group B. 10,32,35,57,79
Answer:
Hence Group A compose of the alternate Addition of "ONE" and "THREE" units
Hence Group B Composes of alternate 22 units addition and 3 units addition.
Step-by-step explanation:
Given:
Two groups as A and B with number in certain patterns as
To Find:
What is that certain pattern in numbers?
Solution:
Group A includes the following numbers as ,
0,1,4,5,8
Here 1st number=0 then 2nd number =1
So in between this addition is 1 is present
And then 3rd number =4 and 4th number=5
so there alternate addition of "one"(1) present
Now in 3rd and 2nd number there is addition of 3 units
And in 5th and 4 number there is addition of 3 units .
Hence this group compose of the alternate Addition of "ONE" and "THREE" units.
Group B includes the following number as ,
10,32,35,57,79
So here 1st number is 10 and 2nd number is 32 (Addition of 22 units).
Further alternate 4th 57 and 3rd number is 35 (addition of 22 units).
For 3rd number is 35 and 2nd number is 32 (addition of 3 units)
For 6th number will be is 82 and 5th number is 79 (addition of 3 units).
Hence this group Composes of alternate 22 units addition and 3 units addition.
inal answer:
The sorting rule for the numbers in Group A and Group B is based on their units digit, where numbers that end in 0 or 5 are placed in Group B, and other numbers are in Group A.
Explanation:
The student has asked to describe the sorting rule for the numbers in two groups, Group A and Group B. Looking at Group A (0, 1, 4, 5, 8) and Group B (10, 32, 35, 57, 79), the sorting rule appears to be that numbers ending in either 0 or 5 are placed in Group B, while the others are placed in Group A.
To elaborate, we can see that:
Numbers in Group A do not end with either 0 or 5.
Numbers in Group B all end with a 0 or a 5.
This pattern suggests that the sorting rule is based on the units digit of each number.

How many square inches greater is the area of a 30-inch circular mirror than an 18-inch circular mirror?
Answer:
Area of a 30-inch circular mirror is greater than area of a 18-inch circular mirror by 452.16 square inches.
Step-by-step explanation:
We are given the following in the question:
Mirror 1:
[tex]d_1 = 30\text{ inches}\\\\\Rightaroow r_1 = \dfrac{30}{2}=15\text{ inches}[/tex]
Area of mirror 1 = Area of circle
[tex]A_1 = \pi r_1^2[/tex]
Putting values, we get,
[tex]A_1 = 3.14\times (15)^2=706.5\text{ square inches}[/tex]
Mirror 2:
[tex]d_1 = 18\text{ inches}\\\\\Rightaroow r = \dfrac{18}{2}=9\text{ inches}[/tex]
Area of mirror 1 = Area of circle
[tex]A_2 = \pi r_2^2[/tex]
Putting values, we get,
[tex]A_2 = 3.14\times (9)^2=254.34\text{ square inches}[/tex]
Difference between area =
[tex]=A_1-A_2\\=706.5-254.34\\=452.16\text{ square inches}[/tex]
Thus, area of a 30-inch circular mirror is greater than area of a 18-inch circular mirror by 452.16 square inches.

The letters that form the word MATHEMATICS are placed in a bowl. Are the odds favorable or unfavorable that he will choose a letter that is a vowel followed by a "T"?
Answer:
4/11 and 2/11
Step-by-step explanation:
The total number of letters in the word mathematics is 11, making the denominator 11. There are 4 vowels and 2 Ts. That is the number of possibilities for each one.
The odds of choosing a vowel followed by a 'T' from the word 'MATHEMATICS' are unfavorable, approximately 5.45%. This is calculated based on the individual probabilities of first drawing a vowel, then drawing a 'T'.
Explanation:The word 'MATHEMATICS' contains 11 letters, which includes 3 vowels (A, A, and E) and 2 'T's. The scenario of drawing a vowel followed by a 'T' implies a two-step process: first drawing a vowel, then drawing a 'T'. We must consider these as two separate events.
For the first draw, the chance of drawing a vowel is 3 out of 11. If successful, then the word left is 'MTHMATICS', a total of 10 letters, 2 of which are 'T's. So the chance of drawing a 'T' on the second draw is 2 out of 10.
The total probability of both events occurring is the product of their individual probabilities. So (3/11) * (2/10) = 6/110 = 0.0545, or approx. 5.45%. This can be categorized as unfavorable odds because the percentage is quite low.

Final answer:
The area of the larger square is four times the area of the smaller square, as the side lengths are doubled, resulting in the area increasing by the square of the factor of increase (2^2 = 4).
Explanation:
When Marta has a square with a side length of 4 inches, and she has a second square with dimensions that are twice as large, the area of the larger square can be found by squaring the ratio of the side lengths. In this case, the larger square will have side lengths of 8 inches because they are twice as long. To determine how the area of the larger square compares to the area of the smaller square, we can use the formula for the area of a square, which is side length squared (s^2).
The area of the smaller square is 4 inches * 4 inches = 16 square inches. If we double the side length to get the larger square, its sides will be 8 inches, so its area will be 8 inches * 8 inches = 64 square inches. Therefore, the area of the larger square will be four times the area of the smaller square because 64 square inches is four times 16 square inches (4^2 = 16, which means four times more area).
