<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish

Answer:
Here are two ways of writing it. I hope this helps!
Answerep-by-step explanation:
Get m by itself.
-6+m=11
6. 6
0. 17
M=17
I can't see any slick, easy way to tell without finding
the intercepts, so here goes:
The y-intercept is the value of H(n) when 'n' is zero.
H(0) = -13(0) - 421
= - 421 .
The n-intercept is the value of 'n' when H(n) is zero.
0 = -13n - 421
Add 13n to each side: 13n = - 421
Divide each side by 13 : n = - 421/13 = - 32.4...
Connor should set up the viewing window so that 'n' displays
at least down to - 33 , and H(n) displays at least down to - 421 .
Answer:
a) P=0.2503
b) P=0.2759
c) P=0.3874
d) P=0.2051
Step-by-step explanation:
We have this information:
25% of American households have only dogs (one or more dogs)
15% of American households have only cats (one or more cats)
10% of American households have dogs and cats (one or more of each)
50% of American households do not have any dogs or cats.
The sample is n=10
a) Probability that exactly 3 have only dogs (p=0.25)
b) Probability that exactly 2 has only cats (p=0.15)
c) Probability that exactly 1 has cats and dogs (p=0.1)
d) Probability that exactly 4 has neither cats or dogs (p=0.5)
