Answer:
ok!
Step-by-step explanation:
the mean is 8.125 and the median is 7
If William has 195 marbles, let's find 4/5 of that.
195 * 4/5 = 156
156 is 2/5 of the marbles Daniel has.
Now we must multiply by the reciprocal
156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles
Daniel has 390 marbles.
A F is 309. 16 + 5 + 30 = 51. 360 - 51 = 309
Hope this helped :D
Answer:
Step-by-step explanation:
if m and n are irrational number then the product of mn sometimes rational and sometime irrational
ex: √5 *√2=√10 irrational
ex: √8*√2=√16=4 rational
b-y=|x|+3
explain why |x|+3≥|x+3|
absolute value of any number is always positive
x |x|+3 ≥ |x+3|
1 4 = 4 in this case equal
2 5 5
-2 5 ≥ 1 in this case |x|+3≥|x+3|
in case of negative value of x then |x|+3>|x+3|
