The problem can be written as the following equation...

1(cost of table)+4(cost of chair)=total$spent
plug in the data
1(599.99)+4(89.59)=total$spent
599.99+358.36=total$spent
958.35=total$spent

Answer=958.35$

Using the concept of probability and the arrangements formula, there is a

0.002 = 0.2% probability that the first 8 people in line are teachers.

----------------------------------

A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which they are positioned is important, and all people will be positioned, and thus, the arrangements formula is used to find the number of outcomes.

The number of possible arrangements from a set of n elements is given by:

$A_n = n!$

----------------------------------

The desired outcomes are:

First 8 people are teachers, in 8! possible ways.
Last 4 are students, in 4! possible ways.

Thus, $D = 8! \times 4!$

----------------------------------

For the total outcomes, number of arrangements of 12 people, thus:

$T = 12!$

The probability is:

$p = \frac{D}{T} = \frac{8! \times 4!}{12!} = 0.002$

0.002 = 0.2% probability that the first 8 people in line are teachers.

I need an explanation, I don't understand them

Anettt [7]

The value of the fractions will be:

1. 8 13/20

2. 2 4/5

3. 5/6

<h3>How to explain the fraction?</h3>

1. 6 1/4 + 2 2/5

LCM of 20

6 1/4 + 2 2/5.

6 5/20 + 2 8/20

= 8 13/20

2. 1 1/5 × 2 1/3

= 6/5 × 7/3

= 42/15

= 14/5

= 2 4/5

3. 3 1/3 - 2 1/2

= 3 2/6 - 2 3/6.

= 5/6

Time sensitive question. Find the sum of the first 26 terms of an arithmetic series whose first term is 7 and 26th term is 93.

lisabon 2012 [21]

ANSWER

$S_{26}=1300$

EXPLANATION

The sum of an arithmetic sequence whose first term and last terms are known is calculated using

$S_{n}= \frac{n}{2} (a + l)$

From the given information, the first term of the series is

$a = 7$

and the last term of the series is

$l = 93$

The sum of the first 26 terms is

$S_{26}= \frac{26}{2} (7 + 93)$

$S_{26}= 13 (100)$

$S_{26}=1300$

The human population doubles approximately every 50 years if there were 2.5 million people in 1950 how many people are forecaste

Margarita [4]

The equation that would let us determine the number of people or population at a certain year is calculated through the equation,

A(t) = A(o)(2^(t - 1950)/50)

Substituting the known values,

A(t) = (2.5 million people)(2^(2100 - 1950)/50))

A(t) = 20 million

Answer: 20 million people
