Answer:
To find the geometric mean of two numbers, just find the product of those numbers and take the square root!
Step-by-step explanation:
Answer:
y = x² + 2
Step-by-step explanation:
Given
x = 
( square both sides )
x² = y - 2 ( add 2 to both sides )
x² + 2 = y
Answer:
Step-by-step explanation:
the whole bag is made of 5 orange +4blue+3 green= 12 marbles
P of orange than green = P orange * P green = 5/12 * 3/12 = 15/144 = 5/48
you multiply when the events depend on each other to happen, so for the orange and then green to happen you need the orange and also the green
Answer:
17 cows and 6 geese
Step-by-step explanation:
1. set up two equations:
C + G = 23 (number of cows and geese = total number of animals)
4C + 2G = 80 (cows have 4 legs, geese have 2 legs and the total # of legs is 80)
2. 2(C+G)=2(23) ===> 2C + 2G = 46
3. subtract 4C + 2G = 80 and 2C + 2G = 46 to equal 2C=34, divide by 2 and C=17 (17 cows)
4. apply 17 back to the original (C + G = 23) equation to get: 17 + G = 23, subtract 17 from 23 and G=6 (6 geese)
i hope the way i explained it was clear! :)
