2^9 - 2^4 = 496
when you multiply exponents, you just add the two (4 and 5) and keep the coefficient the same.
when you multiply by an exponent (^2), you multiple the exponents and keep the coefficient the same.
Answer:
v > -25/p
r = -5 +7/3w
Step-by-step explanation:
-vp + 40 < 65
Subtract 40 from each side
-vp + 40 -40< 65-40
-vp < 25
Divide by -p. Remember to flip the inequality
-vp/-p > 25/-p
v > -25/p
7w - 3r =15
Subtract 7w from each side
7w -7w- 3r =15-7w
-3r = 15-7w
Divide by -3
-3r/-3 (15-7w)/-3
r = -5 +7/3w
Answer:
10.55% probability
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.
1 Bach CD, from a set of 4.
1 Beethoven CD, from a set of 6.
1 Brahms CD, from a set of 3.
1 Handel CD, from a set of 2.
So, D=144
4 CDs from a set of 4+6+3+2 = 15.
So, T= 1365
p= D/T= 144/1365 = 0.1055
10.55% probability that she will choose one by each composer
