A fabric store prices cotton fabric using a proportional relationship between the length
of fabric (in yards) and the cost in dollars.
If 0.2 yards of fabric costs $1.50, what is the constant of proportionality?
PLEASE ANSWER QUICKLY

Answers

Answer:

7.5 dollars per yard

Step-by-step explanation:

you have 0.2 yards and constant of proportionality is when its constant so you make 0.2 into 1. you multiply it 5 times. so you also multiply 1.50 5 times too. which gets you to 7.5 or $7.50.

Let X be a random variable with the following probability distribution.
x -3 6 9
f(x) 1/6 1/2 1/3
(a) Find μg(x), where g(X)=(2X+1)2.
(b) Find the standard deviation of g(X)

Answers

It looks like you're saying

[tex]f_X(x) = \begin{cases}\dfrac16&\text{if }x=-3 \\\\ \dfrac12&\text{if }x=6\\\\\dfrac13&\text{if }x=9\\\\0&\text{otherwise}\end{cases}[/tex]

(a) Given g(X) = (2X + 1)², the mean of g(X) is

[tex]E[g(X)] = \displaystyle \sum_{x\in\{-3,6,9\}} g(x) f_X(x) \\\\ = g(-3)f_X(-3) + g(6)f_X(6)+g(9)f_X(9) = \frac{25}6 + \frac{169}2 + \frac{361}3 = \boxed{209}[/tex]

(b) First compute the second moment of g(X) :

[tex]E[g(X)^2] = \displaystyle \sum_{x\in\{-3,6,9\}} g(x)^2 f_X(x) \\\\ = g(-3)^2f_X(-3) + g(6)^2f_X(6)+g(9)^2f_X(9) = \frac{625}{6} + \frac{28561}{2} + \frac{130321}{3} = 57825[/tex]

Then the variance of g(X) is

[tex]\mathrm{Var}[g(X)] = E[g(X)^2] - E[g(X)]^2 = 57825 - 209^2 = 14144[/tex]

The standard deviation is the square root of the variance:

[tex]\sqrt{\mathrm{Var}[g(X)]} = \sqrt{14144} \approx \boxed{118.93}[/tex]

Mrs. Smith's class is working on a variety of science experiments. Each
student must complete one experiment with each of the other students in
the class. There are 12 students in the class. How many different groups
will be made by the end of the experiments ? Each pair of students can
only be together once.

Answers

Answer:

66

Step-by-step explanation:

If there are  n  students, then the number of pairs is [tex]\frac{n(n-1)}{2}[/tex].

With 12 students, [tex]\frac{12(12-1)}{2} = \frac{132}{2}=66[/tex] pairs can be formed.

The reason the formula works is this:  Each of the 12 students can be paired with 11 other students (no student is paired with him/her self).  But counting 12 x 11 = 132  counts each pair twice.  Example: student A can be paired with student B,..., student B can be paired with student A.  The pair was counted two times.

See the attached image that shows pairings of 5 students.  There are

5(5 - 1)/2 = 5(4)/2 = 10 pairs.

15. The total consumption of fruit juice in a
particular country in 2006 was about
2.28 x 109 gallons. The population of that
country that year was 3 x 108. What was the
average number of gallons consumed per
person in the country in 2006?

Answers

Answer:

total amount of fruit juice consumed is 2.28 x 10^9

total population = 3 x 10^8

per person is

total consumption / total population

therefore;

2.28 x 10^9/3 x 10^8

= 7.6 gallons per person

hope it's helpful

The average number of gallons consumed per person in the country was 7.60 gallons per person.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Given that,

Total consumption of fruit juice 2.28 x 10⁹ gallons

The population of that year = 3 x 10⁸

The average number of gallons consumed per person ⇒

2.28 x 10⁹ / 3 x 10⁸

⇒ 22.8 x 10⁸ / 3 x 10⁸

⇒ (22.8/3) × 10⁸/10⁸

⇒ 7.6

Hence "The average number of gallons consumed per person in the country was 7.60 gallons per person".

To put this into slope-intercept form (y=mx+b), you need to solve the equation for y.

4x + 7y = 14

First move the 4x to the right by subtraction.

Then isolate the y by dividing everything on both sides by 7. Be sure to divide **everything** by 7.

The number line should be broken into segments. Whether each represents 1, 2, or 5. You can multiply 5 by 2 simply by taking the value of 5 and multiplying that segment by 2. (So if the value of one segment is 5, the answer is 2 segments. Or if the value of the segment is 1, then the answer is ten segments.) kinda confusing but I hope that helps.
