Answer:
Deductive reasoning is a method of logical thought that begins with a general concept and arrives at a particular conclusion. It is often referred to as top-down thought or shifting from general to particular.
Step-by-step explanation:
Here are some examples:
- Elephants have cells in their bodies, and all cells have DNA. ...
- All horses have manes.
- Acute angles are less than 90 degrees. This angle is 40 degrees, so it must be an acute angle.
- All noble gases are stable.
To find place value you go digit by digit. There are ones place's, tens place's, and hundreds place's.
1 and a half gallons is 24 one cup servings
1 gallon=16 cups
1/2gallon=8cups
8+16=24
I think this is what you mean. I don't know why the Latex didn't work. Good for you that you can use it.


Reduce the 4/28 to 1/7

Make the 2 minuses into a +

56 is the common denominator.

Answer = [23 + 21 + 8] / 56 = 52 / 56 = 13 / 14 When both numerator and denominator are divided by 4
13 / 14 <<<< answer.
Answer:
Explanation:
You can build a two-way relative frequency table to represent the data:
These are the columns and rows:
Car No car Total
Boys
Girl
Total
Fill the table
- <em>30% of the children at the school are boys</em>
Car No car Total
Boys 30%
Girl
Total
- <em>60% of the boys at the school arrive by car</em>
That is 60% of 30% = 0.6 × 30% = 18%
Car No car Total
Boys 18% 30%
Girls
Total
By difference you can fill the cell of Boy and No car: 30% - 18% = 12%
Car No car Total
Boy 18% 12% 30%
Girl
Total
Also, you know that the grand total is 100%
Car No car Total
Boy 18% 12% 30%
Girl
Total 100%
By difference you fill the total of Girls: 100% - 30% = 70%
Car No car Total
Boy 18% 12% 30%
Girl 70%
Total 100%
- <em>80% of the girls at the school arrive by car</em>
That is 80% of 70% = 0.8 × 70% = 56%
Car No car Total
Boy 18% 12% 30%
Girl 56% 70%
Total 100%
Now you can finish filling in the whole table calculating the differences:
Car No car Total
Boy 18% 12% 30%
Girl 56% 14% 70%
Total 74% 26% 100%
Having the table completed you can find any relevant probability.
The probability that a child chosen at random from the school arrives by car is the total of the column Car: 74%.
That is because that column represents the percent of boys and girls that that arrive by car: 18% of the boys, 56% of the girls, and 74% of all the the children.
