Answer:
y = 3x + 2 is the equation
Step-by-step explanation:
y intercept is where x is 0 that means y intercept is 2.
slope is change in y over change in x which is 3
Answer:
<em>There are 1700 books in the library.</em>
Step-by-step explanation:
<em>If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.</em>
If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.
If 1% is 17 books, then 17*100=100% of books.
There are 1700 books in the library.
Answer:
A. 1, 287 ways
B. 154,440 ways
Step-by-step explanation:
A. We want to choose 5 objects from a total 13, without considering the order in which they are chosen.
The correct way to do this is by using the combination formula since order is not considered;
Thus we have ; 13 C 5 read as 13 combination 5;
Mathematically, n C r is ; n!/(n-r)!r!
Thus, we have ;
13!/(13-8)!8! = 13!/5!8! = 1,287 ways
B. By considering order, we shall be using the permutation formula;
Mathematically n P r = n!/(n-r)!
Read as n permutation r;
Using the numbers involved, we have ; 13 P 5
= 13!/(13-5)! = 13!/8! = 154,440 ways
Answer:
D
Step-by-step explanation:
Neither the table and the graph is correct.
YEAH OFC SHAWTY!
- so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powers
- For B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9
- For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5
- for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powers
I cant do 2 right now, but i will in a minute
<u>And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first. </u>
