(10 POINTS AND BRAINLIEST)Kathy spent $15.60 at the post office. She paid $11.40 to send a package to her aunt and bought stamps with the rest of the money. If Kathy bought 10 stamps, which equation can be used to find x, the cost of each stamp.A.15.60 = 11.40 + 10x B.15.60 = 11.40 + (10 – x) C.15.60 = 10(11.40 + x) D.15.60 = 11.40x + 10

I WILL GIVE BRAINLIST**Lara wants to know if the number of words on a page in her English book is generally more than the number of words on a page in her history book. She takesa random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book*Mean*English- 48.9 History 40.5*Median*English- 52History- 44*Mean absolute deviation*English- 9.2History- 1.3Lara claims that because the mean number of words on each page in the English book is greater than the mean number of words on each page in the historybook, the English book has more words per page. Based on the data is this a valid inference?A. Yes, because there is a lot of variability in the English book dataB. Yes, because the mean is larger in the English bookC. No, because the mean is larger in the English bookD. No, because there is a lot of variability in the English book data

I have a box of replacement parts that I need to choose one from and place into my tortilla making machine. These parts come in two types: Type 1 has a failure rate of .4, and Type 2 has a failure rate of .75. I also know that, in that box, 30% of the replacement parts are of Type 1. There's no other way to tell the two types apart from one another.I choose a replacement part from the box at random, a place it into the machine and I use the machine to make 30 tortillas; of these, I find that 16 of the tortillas it created are square (failures).Question: What is the probability that I picked a Type 1 part?
