Answer:
GE = 3 cm
Step-by-step explanation:
BE = 9 cm
Since G is the centroid, therefore:
=> Centroid theorem
Plug in the value
GE = 3 cm
Answer:
0.677
Step-by-step explanation:Add up the values in the plan A column. There are 10+12+16 = 38 people who prefer plan A.
Add up the values in the "40-49" row to find that 16+8 = 24 people are ages 40 to 49.
We have 38+24-16 = 46 people who either prefer plan A, are aged 40-49, or fit both descriptions. I subtracted off 16 because those 16 people were counted twice when adding 38 and 24.
An alternative way to get this value of 46 is to add up everything that is in column1 or row 3 (or both). So that would get 10+12+16+8 = 46.
Now add up everything in the table to find out how many people were surveyed total. That would be 10+7+12+15+16+8 = 68 people overall.
The probability of someone liking plan A, or being age 40-49, or both is 46/68 = 0.6765 approximately. Rounding to 3 decimal places gives 0.677
You follow the same steps as you would normally, but you can count how many units down it is, instead of how far up.
Total amount=9 chicken.($5/chicken)+15 burguer meals.(6$/burquer meal)=
=$45+$90=$135.
Percent (chicken meals)=($45.100%) / $135=33,33%.
Solution: 33,33%.
All sides of a square are equal in length and there are four sides to a square so the equation would be 6*4 or 6+6+6+6, which equals 24.
