You need to use the grids to draw rectangles which meet the requirements to help you put the answers in on the right.
1) Short side of 7 and long side of 9.
2) Short side of 9 and long side of 10.
3) Short side of 3 and long side of 8.
4) Short side of 4 and long side of 9.
5) Short side of 3 and long side of 5.
6) Short side of 6 and long side of 8.
7) Short side of 1 and long side of 2
8) Both sides 10 (this is technically a square).
9) Short side of 6 and long side of 9.
10) Short side of 7 and long side of 8.
11) Short side of 2 and long side of 3.
12) Short side of 6 and long side of 9.
You can draw these a few different ways to still get a correct result, so above are just one way of doing it.
Answer:
C) At most one sample is mutated
Step-by-step explanation:
If there are 15 samples, it means that 15 is the total (100%) of samples. Then, if we know that there is a chance that 3% are mutated, then we calculate the 3% of 15:

This means that at most one sample is mutated, as this result is not zero (we discard answer A), and 0.45 is not more than half of the samples.
Answer:
(b) Expected number of male kitten E(x) = 1
(c) Standard deviation is ±
.
Step-by-step explanation:
Given that,
Number of kittens in a group are 10. Out of these 5 are female.
To find:- (a) create a probability model of male kitten chosen.
So, total number of kitten = 10
number of female kitten = 5
then, Number of male kitten = 
Now total number of ways to choosing two kittens from group of 10 = 
= 
= 
for choosing (i) No male P(x=0) = P(Two female) = 
= 
(ii) 1 male P(x=1) = P(1 male and 1 female) =
=
=
(iii) 2 male P(x=2)= P(2 male) =
= 
0 1 2
P(X=
)

(b) what is expected number of male kittens chosen ?
Expected number of male kitten E(x) = 
= 
(c) what is standard deviation ?

No,

= 

= ±
