Answer:
Step-by-step explanation:
First I just made -2/5 into a decimal because I like to work with decimals better (which equals -.4)
Then I times everything separately in the parenthesis and got -8x+6
Next you move the 6 over to the left side of the equals sign which would make the equation be -6 = -8x
Lastly you divide the -8 from -6 and you get X = 3/4
Answer:
The probability they have one boy and one girl = 0.50 = 50 %
Step-by-step explanation:
Here the family has two children, we need to find what is the probability they have one boy and one girl.
Probability for babies are boys = 51.3% = 0.513
Probability for babies are girls = 1 - 0.513 = 0.487
The probability they have one boy and one girl = 1 - probability that they have two boys - probability that they have two girls
The probability they have one boy and one girl = 1 - 0.513² - 0.487² = 0.499 = 0.50
The probability they have one boy and one girl = 0.50 = 50%
You subtrscy the bigger number (2010's population) by the smaller one (1910's population). 237194-608660= 371,466.
When you round to the 100's you check the 10's place. If 5 or higher add a 1 to the hundreds place, and make the 1's and 10's place 0. If lower don't add anything and make the 1's and 10's place into 0s.
When you round it, you will get 371,400
