Here is me with more issues. Melissa’s birthday is next week and she has been receiving cards in the mail with different amounts of money. She has received five gift cards with the following amounts: $10, $20, $25, $30, and $40. If Melissa receives one more card in the mail with $25, what will the standard deviation do, decrease, increase, or stay the same? The picture is also there!

the correct answer is the second option

here's a poem i finished a while ago. i hope you like it and that it inspires you.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
