Answer:
x+y=20
.10x+.25y=3.80
Step-by-step explanation:
In total, there are 40 marbles. 25 of those marbles are green. What I did was divide the number of green marbles by fourth, the total number of marbles. (25/40) You should come up with 0.625. Then you convert the decimal into a fraction. 5/8 is equivalent to 0.625. Thus, 5/8 of the marbles are green.
Hope this helps :)
It’s organized on which is more important and which is least important and they Wright about a subject then they put a picture to tell you about it
A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
Answer:
She wants to take unusually of the good and bad games into account
Step-by-step explanation:
Given that a basketball coach keeps track of the points scored per game for all of her players. A trophy is given to the player with the highest mean score at the end of the season.
Mean vs median:
Mean is the arithmetic average of all the entries while median is the middle entry after arranging in ascending order.
Median is not affected by extreme items but mean is very much affected by unusually high or low scores.
Here since the trophy is decided to be given to the highest mean score it is obvious that
She wants to take unusually of the good and bad games into account
Because of this only, mean is taken instead of median.
