When Hana pours the mixture through a filter,
she will likely to collect a solution of salt in water that passes through the
filter. <span>The activity shows the split-up of solids that
are not soluble from a liquid by means of what we called filtration. It can be
used to separate solids that are not soluble from a liquid, or a precipitate
from the reaction mixture that it made. </span>
Answer;
- A sense
A sense is a system that translates data from outside the nervous system into neural activity, thus giving the brain information about the world.
Explanation;
-The sense or sensory nervous system is a part of the nervous system responsible for processing sensory information.
-A sensory system consists of sensory neurons, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, and balance.
-Senses are transducers from the physical world to the realm of the mind where we interpret the information, creating our perception of the world around us.
A scientific explanation for a set of observations that can be tested and is written with an "if/then" statement is referred to as hypothesis and is denoted as option B.
<h3>What is Hypothesis?</h3>
This is defined as the proposed explanation for a particular phenomenon before several experiments are conducted by others in different parts of the world to confirm its authenticity.
It employs the use of words such as "if/then" which shows its unproven status which is therefore the reason why it was chosen as the most appropriate choice.

c) P(5<X<15); (d) the value of the constant c such that P(|X −10|≥c) ≤ 0.04
Answer:
a) 0.4444
b) 0.5556
c) 0.8400
d) 10
Explanation:
Chebyshev’s theorem states that
P(|X - μ| ≥ kσ) = 1/k²
μ = Mean = 10
σ = standard deviation = √variance = √4 = 2
a) P(|X −10|≥3)
Comparing this with P(|X - μ| ≥ kσ)
It is evident that kσ = 3
2k = 3
k = 3/2
k² = 2.25
1/k² = 0.444
P(|X −10|≥3) = 0.444
b) P(|X −10| < 3) = 1 - P(|X −10|≥3)
And P(|X −10|≥3) was found in (a) to be 0.444
So,
P(|X −10| < 3) = 1 - P(|X −10|≥3) = 1 - 0.4444 = 0.5556
c) P(5<X<15) = P(|X-10|<5) = 1 - P(|X-10|≥5)
P(|X-10|≥5) = 1/k²
Comparing with P(|X - μ| ≥ kσ) = 1/k²
where 2k = 5
k = 5/2
k² = 6.25
1/k² = 0.16
P(|X-10|≥5) = 0.16
P(5<X<15) = P(|X-10|<5) = 1 - P(|X-10|≥5) = 1 - 0.16 = 0.8400
d) P(|X −10|≥c) ≤ 0.04
1/k² = 0.04
k = 5
c = kσ = 5×2 = 10
