You are saving for a skateboard. Your aunt gives you $45 to start and you save $3 each week. The expression 45 + 3w gives the amount of money you save after w weeks. How much money will you have after 20 weeks? Is this enough money to buy the skateboard?

$105.  I don't know about how much the skateboard is but on an average skateboard yes it is enough.

Step-by-step explanation:

If you get $3 a week and you have lived 20 more weeks. You would multiply 3 by 20 and get $60. Then you would add $60 to $45 and get $105. The average skateboard costs $70. So yes, a skateboard could be bought for $105. Hope this helps! Have a great day!

Step-by-step explanation:

Given that a comic-strip writer churns out different numbers of comic strips each day. The writer logged the number of comic strips he wrote each day for 16 days and sorted the data in ascending order to create this data set.

1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 8

Mean = 3.77 and median =3.5

When mean > median, hence positively skewed.

skewness = 0.74

If 5 and 7 are added the data set in ascending order is

1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5,5. 6, 7,8

Mean = 3.7778 and median = 3.5

Difference of mean =0.0078 and

difference of median = 0
