the probability of getting a 2 tree times is
[tex]\frac{1}{6}\cdot\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{216}[/tex]Which are the better statistics to use to compare the team scores

Step 2
The box plot displays the 5 number summary
-Minimum data value
-Maximum data value
-Median
-First Quartile, and
Third Quartile
The Interquartile Range (IQR) of the data can also be calculated by finding the difference between the First Quartile, and the third Quartile.
The Interquartile Range (IQR) helps us to determine the variability of the data set. The IQR is often seen as a better measure of spread than the range as it is not affected by outliers.
The median that is gotten from the box pot measures the center tendency of the data. The median is the most informative measure of central tendency for skewed distributions or distributions with outliers.
Therefore, the better statistics to use for comparing the scores of the teams are;
Median and IQR.
Given P250/75R18 tires, what would be the Circumference in inches of the tire?
Given data:
The given radius of the tire is r=18 in.
Th expression for the circumference is,
C=2πr
Substitute the given values in the above expression.
C=2(3.14)(18)
=113.04 in
Thus, the circumference of the tire is 113.04 inn.

A university claims its recent graduates earn an average annual salary of
$45,000. You draw a random sample of 40 recent graduates and find that their
average salary is $46,000, and calculate the standard error of the sample mean
as 436.81. What is the t ratio for this result?
Answer:
t-ratio = 0.362
Step-by-step explanation:
In hypothesis testing,
The t-ratio is given by the formula:
[tex]\dfrac{X-\mu}{s}[/tex]
where μ is the hypothesized mean, X the sample mean and s the sample standard deviation
The Standard Error of the Mean SEM = [tex]\large \text{{$\dfrac{s}{\sqrt{n}}$}}[/tex] where n is the sample size.
We We are given:
X = 46,000
μ= 45,000
SEM = 436.81
n = 40
We can find the sample standard deviation
s = SEM x √n
s = 436.81 x √ 40
s = 2762.3
Therefore
t-ratio = (46000 - 45000)/2762.3 = 0.362
a cylinder shaped popcorn
Answer
Option C is correct.
Volume = 1,413 in³
Explanation
The volume of a cylinder is given as
Volume = πr²h
where
π = pi = 3.14
r = radius of the cylinder = ½ (Diameter) = ½ (10) = 5 inches
h = height of the cylinder = 1.5 feet = 1.5 (12 inches) = 18 inches
The conversion from feet to inches was done using 1 feet = 12 inches
So, we can calculate the volume now
Volume = πr²h
Volume = (3.14) × (5²) × (18)
Volume = 1,413 in³

A family has 6 children. Assume that each child is as likely to be a boy as it is to be a girl. Find the probability that the family has 6 girls if it is known the family has at least one girl.
The probability that the family has 6 girls if it is known the family has at least one girl is; 3.125%
What is the Probability?
We are told that each child has the same chance of being a boy or a girl and as such we can say that probability is 1 in 2, or 0.50 or 50%.
Since the family must have at least one girl, if we assume that the first child is a girl, the the probability of the second child being a girl is 50%.
The probability of the other 5 children all being girls is:
(1/2) * (1/2) * (1/2) *(1/2) * (1/2) = 1/32.
This Probability expressed as a decimal or percentage represents a probability that we have as; 1/32 = 0.03125 = 3.125%.

ryan is buying pencil boxes. he wnats to buy the box that will fit the most markers. he can choose between the following 3 options
Answer:
what r the 3 following options??
Step-by-step explanation:
Given the following: P(A)=0.28, P(B)=0.64, P(B|A)= 0.37, calculate P(A and B)
By definition of conditional probability you know that
[tex]P(B|A)=\frac{P(A\cap B)}{P(A)}[/tex]Now, replace the values that you have and solve for P(A and B)
[tex]\begin{gathered} P(B|A)=\frac{P(A\cap B)}{P(A)} \\ 0.37=\frac{P(A\cap B)}{0.28} \\ \text{ Multiply by 0.28 on both sides of the equation} \\ 0.37\cdot0.28=\frac{P(A\cap B)}{0.28}\cdot0.28 \\ \text{ Therefore,} \\ 0.1036=P(A\cap B) \end{gathered}[/tex]the supplement of an angle is 30 degrees more than the measure of the

Answer:
x = 75°
Step-by-step explanation:
supplementary angles sum to 180°
let x be the angle then x + 30 is the supplementary angle , so
x + x + 30 = 180
2x + 30 = 180 ( subtract 30 from both sides )
2x = 150 ( divide both sides by 2 )
x = 75
x + 30 = 75 + 30 = 105
the angle is 75° and the supplementary angle is 105°

We have to find the parametric representation of the parabola y = (x+7)² - 5, which is represented in vertex form.
Parametric representations use a third variable on which we define x and y.
We will call this variable t.
We can start with defining t as:
[tex]\begin{gathered} t=x+7 \\ \Rightarrow x(t)=t-7 \end{gathered}[/tex]We then have already x in function of t.
Then, we can use the definition of t to find y(t):
[tex]\begin{gathered} y(t)=(x(t)+7)^2-5 \\ y(t)=(t-7+7)^2-5 \\ y(t)=t^2-5 \end{gathered}[/tex]We then have x and y defined in function of t.
Answer: we can represent the parabola in a parametric form as
x(t) = t-7
y(t) = t² - 5
Complete the point slope equation of the line through -2,6 and 1,1
Answer:
3y = -5x + 8
Step-by-step explanation:
Point Slope Equation Of A Straight Line:
y - y1 = m(x - x1)
where m = slope of the line and (x1, y1) is any point on the line
Slope is given by rise/run
For any two point (x1, y1) and (x2, y2) on the line
rise = y2 - y1
and
run = x2 - x1
Given points (-2, 6) and (1, 1)
rise = 1 - 6 = -5
run = 1 - (-2) = 1 + 2 = 3
rise/run = m = -5/3
Equation using the point (1, 1) is
y - 1 = -5/3(x - 1)
y - 1 = -5/3x + 5/3
Multiply both sides by 3 to get
3(y - 1) = 3 x (-5/3)x + 3(5/3)
3y - 3 = -5x + 5
3y = -5x + 8
the numberof blocks has 9 in the ones places.The number in the hundreds place is one more than the number in the tens place. Those two numbers equal 11. How many blocks are there?
Based on the given information, we can express the following
[tex]\begin{gathered} h=1+t \\ h+t=11 \end{gathered}[/tex]Because the digit of hundreds is 1 more the tens, and they sum 11. Let's combine the function to find t
[tex]\begin{gathered} h+t=11 \\ 1+t+t=11 \\ 2t=11-1 \\ t=\frac{10}{2}=5 \end{gathered}[/tex]So, the digit of tens is 5.
Let's find the hundreds.
[tex]h=1+t=1+5=6[/tex]The number of hundreds is 6.
Hence, the number of blocks is 659.The bill at a restaurant came to $136.40. The patrons decided to leave a 15% tip. What was the total bill including tip?

Simplify 3^2 + 3(6 - 2^2) ÷ 6.
Fractions simplification
Apply PEMDAS method. Eliminate parenthesis first.
Then (3^2 + 3•6 - 3•2^2 )/ 6 = (3^2 + 3•6 - 3•2^2 )/ 6
now eliminate exponents
= [3• 3 + 3•6 + 3•4] / 6
= 3•5/6 now multiplicate
3•5= 15
Then
= 15/6 = 2 + 3/6 = 2 + 1/2 = 2.5

cual es la raiz cuadrada de 4096 y 529
The square root of 4096 is 64 and the square root of 529 is 23.
The square root of a number x in mathematics is a number y whose square (the outcome of multiplying the number by itself, or y·y), is equal to x.
For instance, since 4² = (-4)² = 16, 4 and -4 are the square roots of 16.The square root of x is rational if and only if x is a rational integer that can be expressed as the ratio of two perfect squares. (The square root of 2 for proof that this number is illogical; the quadratic irrational for evidence against all non-square natural numbers.) The square root function changes rational numbers into algebraic numbers, which are a superset of rational numbers.The given numbers are 4096 and 529.
Let us find the factors of 4096:
4096 = 2¹²
Therefore the square root of 4096 = √4096 = √(2¹²) = 2⁶ = 64 .
Let us find the factors of 529:
4096 = 23 × 23
Therefore the square root of 529 = √529 = √(23²) = 23 .

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a portion of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Percent refers to one hundred percent.
A decimal is a number divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of full and partially whole quantities.
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction.
A ratio displays the multiplicity of two numbers. A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.
