Answer:
Ordered pair
Definition: An ordered pair is a pair of numbers in parentheses that declare the location of a point on a graph.
Probability helps us to know the chances of an event occurring. The estimated number of left-handed persons in the school is 89.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Given the number of girls is 320, the probability that a girl is left-handed is 0.2. Therefore, the number of girls who are left-handed is,
Number of left-handed girls = (320×0.2) = 64
Given the number of boys is 250, the probability that a boy is left-handed is 0.1. Therefore, the number of boys who are left-handed is,
Number of left-handed boys= (250×0.1) = 25
Hence, the estimated number of left-handed persons in the school is 89.

Where .75 will be on a number line always varies depending on how far out your number line goes. the decimal .75 is also known as 3/4, so the easiest way to find out where 3/4 is on a number line is to divide you number line into 4 even sections. this can be difficult if you have an odd number,, but it will always work as long as you divide the length of your number line by 4 to find out where to make your even sections. below is an example on how this would work:
lets say this is your number line
-------------------------
that number line contains 24 dashes,, so if you take that number (which is the length of the number line) and divide it by 4 you will find where 3/4 is.
24 ÷ 4 = 6
this means that at every 6,, you add 1/4. on the number line it would look like the following:
------I------I------I------
1/4 2/4 3/4
this technique shows you where 3/4/0.75 is on your number line.

Answer: 2535
Step-by-step explanation:
use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)
first ill handle the two innermost parenthesis
(4 + 3(2 - 8))
(4 + 3(-6))
(4 - 18)
-14
now lets move on to the next parenthesis
( 3 - 5^2(-14))
(3 - 25( - 14)
( 3 + 350)
353
now onto the last part of the problem
8^2 + 7 (353)
64 + 2471
2535 :))
Answer:
2.3%
Step-by-step explanation:
18000 = 15000( 1 + i)^8
Divide both sides by 15000
1.2 = (1 + i)^8
Take both sides to the 1/8 power
1.2^(1/8) = 1 + i
1.023051875220463 = 1 + i
Subtract 1 from both sides
i = 0.023051875220463
~ 2.3%
