This image shows the relative frequency of banded and non-banded snails in a population. If the frequency of banded snails decre

ased to 60% and non-banded snails increased to 40%, would you consider the population to be evolving?.

If the frequency changed to 60% and 40%, the population would be evolving.

<h3>What is evolution?</h3>

Evolution is determined as changes in the population of a species. This implies over time one or more changes will occur in a population, these changes are usually a change in the frequency of a trait, in this case, the frequency of snails with/without bands.

<h3>How to identify the evolution?</h3>

The population is evolving if the Hardy-Weinberg equilibrium is lost, this means the alleles are changing from one generation to the other.

Based on this, evolution is occurring in this population of snails.

Find the 45th percentile of the data set. Give your answer to three decimal places.
Schach [20]

The 45th percentile of the data given above (P₄₅) is 16.225.

<h3>What is percentile in statistics?</h3>

Percentile refers to the mathematical or statistical term that is used to indicate the position of a data in relation to others from the sample given.

<h3>How did we arrive at the above figure?</h3>

Step 1 - First all data must be arranged in ascending order:

See the attached table for this.

Step 2 - We compute the position or rank of the 45th percentile.

The formula for percentile position is given as:

((n +1 ) *P)/100

= ((25+1) * 45)/100

= 11.70

Step 3 - Deploy the interpolation method because the position above is not an integer.

The numbers in positions 11 and 12 are where you'll find the 45 percent percentile. Based on the data arranged in ascending order, the values are 15 and 16.75.

The percentile we're seeking for is situated at the value of 11.7 - 11 = 0.7, which is the percentage of the space between 15 and 16.75.

Therefore,

(P₄₅) = 15 + 0.7 x (16.75 - 15)

(P₄₅) =16.225.

The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes
SpyIntel [72]

When she descends the potential energy will decrease at the same rate that the kinetic energy increases.

<h3></h3><h3>How to describe changes in energy?</h3>

We know that we can write the total energy of a moving object as:

E = U + K

Where U is the potential energy and K is the kinetic energy.

In the given case, U will only depend on the height of the girl and it will be maximized when the height is maximum.

K = (1/2)*m*v^2

where m is the mass and v is the velocity.

When the girl is at the highest point, the velocity becomes equal to zero. This happens because at that point she stops going up and starts going down, so the velocity must be zero at that moment.

Then we have K = 0.

E = U.

As she starts going down, the velocity starts increasing and the height decreases, thus, the kinetic energy increases and the potential energy decreases. This relates to the conservation of energy. E will always be the same value, but K and U will depend on the position of the girl.

This means that if the potential energy decreases a quantity e', then the kinetic energy must be increased by that same amount.
