Answer: The most typical symmetric histogram or dot plot has the highest vertical column in the center. This shape is often referred to as being a "normal curve" (or normal distribution). ... Skewed Right (positively skewed) - fewer data plots are found to the right of the graph (toward the larger numeric values).
A roll of tissue paper towels has the given dimensions. Determine, to the nearest hundred, the volume of the roll
*see attachement for the diagram of the tissue paper
Answer:
Volume of the roll = 3,817.04 cm³
Step-by-step explanation:
The diagram of the roll of the tissue paper given is a model of two cylinders:
✔️Bigger cylinder with diameter (d) of 14 cm and height of 27 cm
✔️ Smaller/inner cylinder with diameter (d) of 4 cm and height of 27 cm
Thus:
The Volume of the roll = volume of bigger cylinder - volume of smaller cylinder
✔️Volume of bigger cylinder = πr²h
r = ½(14) = 7 cm
h = 27 cm
Volume of bigger cylinder = π*7²*27
= 4156.33 cm³
✔️Volume of smaller/inner cylinder = πr²h
r = ½(4) = 2 cm
h = 27 cm
Volume of smaller/inner cylinder = π*2²*27
= 339.29 cm³
✅The Volume of the roll = 4156.33 - 339.29 = 3,817.04 cm³

What is a linear equation?A linear equation has one or two variables.No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y if x is given.
Calculation:-
Given initial feight= 16 feet
h(t)= -16t2 + initial height
for 1 second
⇒ h(1)= -16(1)2 +16
⇒ h = -32 +16
⇒ h = -16 ( 16 feet downward i.e penny will tough the ground)

A helicopter pad has a circumference of 47.5 yards. Find the approximate diameter of the helicopter pad. Use 3.14 for π.
Answer:
15.1 yd
Step-by-step explanation:
Since the circumference formula is C = πd, d = C/π
and in this case d = (47.5 yd) / 3.14 = 15.1 yd
The approximate diameter of the pad is 15.1 yd.
The approximate diameter of the helicopter pad is,
⇒ d = 15.12 yards
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
A helicopter pad has a circumference of 47.5 yards.
Now,
We know that;
Circumference of circle = 2πr
Hence, We get;
⇒ 47.5 = 2 × 3.14 × r
⇒ 47.5 = 6.28r
⇒ r = 47.5 / 6.28
⇒ r = 7.56
Thus, the approximate diameter of the helicopter pad is,
⇒ d = 2r
⇒ d = 2 × 17.56
⇒ d = 15.12 yards

What is the midpoint of the line with endpoints (3,-2) and (-3,6)
(0, 2)
Step-by-step explanation:
The coordinates of the midpoint of a line segment is given by
[(x2 + x1)/2 , (y2 + y1)/2]
Let P1 = (3, -2) and P2 = (-3, 6)
x-coordinate:
(1/2)(x2 + x1) = (1/2)[(-3) + 3] = 0
y-coordinate:
(1/2)(y2 + y1) = (1/2)[6 + (-2)] = 2
Therefore, the coordinates of the midpoint whose endpoints are (3, -2) and (-3, 6) are
(0, 2)

what explicit formula describes the pattern of this table
Answer:
y - 6.28 = 3.14( x - 2 )
Step-by-step explanation:
Notice that 6.28 is twice the approximate value of pi: 2(3.14), and that
9.42 is three times pi. We can deduce immediately that the slope of the line passing through (2, 6.28) and (3, 9.42) is 3.14.
Using the point-slope formula for the equation of a straight line, we get:
y - 6.28 = 3.14( x - 2 )

Find the probability of getting heads 2 times in a row, then rolling a 6 sided die and getting
either a 1 or 6.
Answer:
1/12
Step-by-step explanation:
The probability of rolling a die and landing it on heads is 1/2 percent. Flipping the coin another time and landing it on heads is 1/4 percent because you need to multiply when doing probabilities, so 1/2 times 1/2 equals 1/4.
Now moving on, rolling a 6 sided die and getting either a 1 or 6 is 1/3 percent because 1 and 6 are two different numbers you can roll so it's 2/6, and when it's simplified, it's 1/3.
After doing that, to find the probability of the whole equation, you would need to multiply 1/4 times 1/3 which would give you 1/12 as your answer.

b. P-Value: ________
c. Conclusion of test
d. Construct a confidence interveral appropriate for the hypothesis test.
e. Does the confidence interval support conclusion of hypothesis test?
Answer:
Test = 17.143 ;
Pvalue = 0 ;
Reject the Null ;
(-0.028 ; - 0.022) ;
We conclude that content are different.
Step-by-step explanation:
Given that:
μ1 = μ
n1 = 36 ; n2 = 36
x1 = 0.78616 ; x2 = 0.81111
s1 = 0.04444 ; s2 = 0.00752
Test statistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(0.78616 - 0.81111) / √(0.00444²/36 + 0.00752²/36)
- 0.02495 / 0.0014554
= 17.143
Pvalue :
Z < 17.143
Pvalue = 0
Since Pvalue < α ; Reject the Null
The confidence interval using a confidence interval calculator is (-0.028 ; - 0.022)
Since the interval does not contain Zero ; then we reject the Null and conclude that the content are different.

Answer:
distance = 11.1666 miles (round to 11.1667)
11.1667 mi
How I solved it:
Well, I knew that in one hour, she would go 67 miles.
I then divided the hour into 6 sections (10 min, 20 min, 30, 40, 50 and 60)
So, we divide 67/6
and our answer is 11.1666 (round to 11.1667)

another survey of people aged 25-49, a total of 400 people preferred Sauce B. Based on the data
below, how many of those 400 people would be expected to be age 40-44?
Answer:242
Step-by-step explanation:
bc you have 25 to49 adults divide and subtracts & you get 242 , hope this helps !
83 people out of 400 people would be expected to be age 40-44.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
As, 400 people choose sauce B.
In the given table there 302 people who choose sauce B, in which 63 people belongs to group 40-44
So, 63/302= x/400
302*x=63*400
x=83.
Hence, 83 people out of 400 belongs to group 40-44 who choose sauce B.

y-intercept(s):

Step-by-step explanation:
The x-intercepts are (83, 0), and the y-intercepts are (0, 4). Matrixes, like numbers, have reciprocals. In the world of matrices, this reciprocal is known as a "inverse matrix."
What is the inverse matrix?The concept of a matrix's inverse is a multidimensional generalization of the concept of a number's reciprocal: just as the product of a number and its inverse equals one, the product of an identity matrix and a square matrix equals one.
A A-1 = A-1 A = I because the identity matrix I is the inverse of a matrix. An invertible matrix is one that has a non-zero determinant and can have its inverse determined. Finding the inverse of a 2x3 matrix is impossible because it is not a square matrix.
Response: (8 3, 0) are the x-intercepts.
(0, 4 ) are the y-intercepts.
Therefore,
-3 x-2 y=-8
Add 2 y to both sides
-3 x-2 y+2 y = -8+2 y
Simplify
[tex]$$-3 x=-8+2 y$$[/tex]
Divide both sides by -3
[tex]$$\frac{-3 x}{-3}=-\frac{8}{-3}+\frac{2 y}{-3}$$[/tex]
Simplify
[tex]$$x=-\frac{-8+2 y}{3}$$[/tex]
Response: (8 3, 0) are the x-intercepts.
(0, 4 ) are the y-intercepts.
