Step-by-step explanation:

The area A of a triangle is given by

[tex]A = \frac{1}{2}bh[/tex]

where b is the length of the base and h is its height. Solving for h, we get

[tex]h = \dfrac{2A}{b} = \dfrac{2(72\:\text{m}^2)}{28\:\text{m}}[/tex]

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.

Step-by-step explanation:

An equivalent set is a set that has equal numbers or items.

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]

B) [tex]\sqrt{13}[/tex]

Step-by-step explanation:

1.  [tex]d = \sqrt{(-3-0)^2+(-2-0)^2}[/tex]

2. [tex]d=\sqrt{(-3)^2+(-2)^2}[/tex]

3. [tex]d=\sqrt{9+4}[/tex]

4. [tex]d=\sqrt{13}[/tex]

[tex]\sqrt{13} = 3.60555..[/tex]

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.

Answer:

  2/3

Step-by-step explanation:

You can see from the diagram that the shaded 1/4 of the second rectangle has the same dimensions as 2 of the 3 shaded parts of the first rectangle.

  2/3 of 3/8 is in 1/4

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.

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".

Step-by-step explanation:

Well,you can count the zeros that will give you the exponent.

For example:

100 has two zeros so the exponent form will be

[tex] {10}^{2} [/tex]

For 10,000,it has 4 zeros.The exponent form is

[tex] {10}^{4} [/tex]
