Answer:
Step-by-step explanation: The second book has 346 pages, the 3rd book has 264 pages. Together they have a total of 346+264 = 610 pages. To find how many pages less is book one than two and 3 combined subtract 137 from the total for books 2 and 3 (610 - 137 = 473). Book 1 is 473 pages less than the other 2 books.
Answer:
An invoice was paid an average of 20 days after it was received.
Mean =
Standard deviation =
Now we are supposed to find what percent of the invoices were paid within 15 days of receipt i.e.P(x<15)
Formula :
At x = 15
Substitute the values
Refer the z table for p value
So, p value = 0.1587
So, 15.87% of the invoices were paid within 15 days of receipt

Answer:
85.55
Step-by-step explanation:
i dont know if im right but
1) i took 12 × $6.79 for the total cost ehich totalled out to 81.48
2) i used calcutator.net and put in the sales tax 5% ($4.07)
3) it gave me $85.55 after adding the tax
y = -4x + 3 this line has slope = -4
parallel lines, slope is the same so slope of new line is also equal -4
passing thru (8, -3)
y = mx + b
b = y - mx
b = -3 - (-4)(8)
b = -3 + 32
b = 29
equation:
y = -4x + 29
hope it helps
