A party is thrown where 25 tables are used. Each table either sits 4 people or 6 people. A total of 116 people can be sat at the

Soloha48 [4]

Answer:

(a) 4 y + 6 s = 116 represents the given situation.

(b)There are 8 six- person tables at the party.

Step-by-step explanation:

Here, the total number of tables = 25

Let y : Represent the number of four person tables.

s : Represents the number of six person tables.

Total people seated at all tables = 116

Now, the number of people seated at table of 4 = y x 4 = 4 y

the number of people seated at table of 6 = s x 6 = 6 s

(a) Total People Seated = People seated at { 4- table + 6 table}

⇒ 116 = 4 y + 6 s

Hence, 4 y + 6 s = 116 represents the given situation.

(b) Total tables are 25. ⇒ s + y = 25

Hence, the givens system of equations are:

4 y + 6 s = 116 ........ (1)

s + y = 25 ............ (2)

Solving the above system, we get, substitute y = 25 - s in (1)

4 y + 6 s = 116 ⇒ 4(25-s) + 6s = 116

or, 100 - 4s + 6s = 116

or. 2s = 16

or, s = 16 / 2 = 8 ⇒ s = 8

Hence, there are 8 six- person tables at the party.

Rational expressions are often used in combining rates of work.

denis-greek [22]

Rational expressions are often used in combining rates of work. Therefore, it's true.

<h3>What is rational expression?</h3>

It should be noted that a rational expression is simply defined by a rational fraction.

They're are used in combining rates of work. Fir example, if Mr John performs 1/2 of his work and does 1/3 on another day. This can be expressed as:

= 1/2 + 1/3

= 5/6

A simple random sample of size n = 20 is obtained from a population with population mean 64 and population standard deviation 17

eimsori [14]

Answer:

Kindly check explanation

0.57691

0.4719

Step-by-step explanation

A.) The distribution of sample means must follow a normal distribution ;

Mean = 64 ; Standard deviation = 17 ;

Standard Error = s/sqrt(n) = 17 / sqrt(20) = 3.8013155

N(64 ~ 17)

Given that:

mean (m) = 64

Sample size (n) = 20

Standard deviation (s) = 17

Find

P(x < 67.3)

Z = (x - m) / s

Zscore = (67.3 - 64) / 17

Zscore = 0.1941176

P(Z < 0.194) = 0.57691 (Z probability calculator)

Zscore = (65.2 - 64) / 17

Zscore = 0.0705882

P(Z > 0.0705) = 0.4719 (Z probability calculator)

A high school soccer team is going to Columbus, Ohio to see a professional soccer game. A coordinate grid is superimposed on a h

V125BC [204]

The point halfway between the two cities would be the midpoint, which is found by averaging the x and y coordinates. In this case the point would be ((3+7)/2, (4+1)/2) = (5, 2.5). The distance between the stadium and the high school can be found using the distance formula and then multiplying by 10.9 miles. That would get us 10.9sqrt((7-3)^2+(4-1)^2) = 54.5 miles if I did that mental math right.
