Answer:
-x² + 8x - 7
Step-by-step explanation:
Step 1: Write expression
(7 - x)(x - 1)
Step 2: FOIL (First Outside Inside Last)
7x - 7 - x² + x

-x² + 8x - 7
Answer: There would be 745 books at the end of month 10.
Step-by-step explanation:
Since we have given that
Number of books initially = 80
Rate of growth = 25% = 0.25
t = 10 months
We need to find the number of books that are expected at the end of month 10.
As we know the formula for "Compound interest":
Hence, there would be 745 books at the end of month 10.
Y = 6.3x + 67.4
The average height of a 5 year old boy is
6.3(5) + 67.4 = 31.5 + 67.4 = 98.9 cm
Answer:
A. 10, 15, 15, 18, 22, 25, 28, 35, 36
Step-by-step explanation:
Stem and leaf plot
1 | 0 5 5 8
2 | 2 5 8
3 | 5 6
Example : 1 | 0 means 10
So, considering the examples :
1 | 0 5 5 8
10,15,15,15,18
2 | 2 5 8
22,25,28
3 | 5 6
35,36
So, the data set is 10,15,15,15,18,22,25,28,35,36
So, Option A is true
