Answer:A
Step-by-step explanation:
3 units + 1 unit = 4 units (the sum of 2nd and 3rd)
4 units + 4 units = 8 units (sum of all properties)
*The other 4 units comes from the first property as the first property's value is the same as the sum of the 2nd and 3rd.*
8 units = $560 000
1 unit = $560 000÷8 = $70 000 (3rd)
3 units = 3x$70 000= $210 000 (2nd)
$210 000 + $70 000=$280 000 (1st)
Ans:
1st property costs $280 000.
2nd property costs $210 000.
3rd property costs $70 000.
Considering the sequences given, the first number that appears in both sequences is given by: 45.
<h3>What numbers appear in the first sequence?</h3>
The rule is multiply by 3 starting from 5, hence the numbers are:
(5, 15, 45, 135, ...).
<h3>What numbers appear in the second sequence?</h3>
The rule is add 9 starting from 18, hence the numbers are:
(18, 27, 36, 45, ...).
45 is the first number that appeared in both sequences.

Answer:
0.01863, yes preference
Step-by-step explanation:
given that a class consists of 12 boys and 12 girls. The teacher picks five students to present their work to the rest of the class and says that the five students are being selected at random
Here selecting any 5 students from the group of total 24 students is combination because order does not matter.
Total no of ways of selecting any 5 from total 24 =
No of ways of selecting only 5 girls = No of ways of selecting random 5 girls from total 12 girls
=
a) the probability be that all five students
selected are girls=
b) Since the probability for selecting all girls is very small and near to 0, it is unusual to select all girls if done at random. Hence the teacher had a preference for girls.
