Answer:
The mean of the data set = 
Step-by-step explanation:
Please check the dot plot which is attached below.
As we know that we can determine mean from the dot plot by adding the numbers and then divide the resulting sum by the number of addends.
From the dot plot it is clear that:
So adding all the dots with respect to their values on the plot number by the total number of dots.
Thus
Mean = (1+1+1+2+2+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6) ÷ 22
Hence, the mean of the data set =
Answer:10
Step-by-step explanation:
if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15
Answer:
x = 55, y = 45
Step-by-step explanation:
add both equations: 2x = 110, x= 55, input back in to get y = 45
He is buying one large tree, so subtract the cost of a large tree from the total:
1400 - 200 = 1200
He can spend 1200 on small trees.
Divide 1200 by the cost of a small tree to find how many small trees can be bought:
1200 / 150 = 8
He can buy 8 small trees.
Total number of trees = 8 small + 1 large = 9 total
