A bimodal distribution is one with two modes; in other words, two observations with the same frequency of occurrence. A bimodal distribution has its mean equal to its median if it is a symmetric distribution and otherwise if it is an asymmetrical distribution.
colleen is searching online for tickets two weeks ago the cost to fly from orlando to hartford was 200$ . Now the cost is 335$ what is the percent increase what would be the percent increase if the airline charges an additional $50 baggage fee with the new price. the percent increase of the airline ticket is...... and i will give a brainlest to the best
The percentage increase for flight tickets to fly from orlando to hartford would be = 67.5% and 92.5% when there is an additional $50 to the new price.
What is percentage Increase?Percentage increase is defined as the rise in the quantity or amount for an object which is converted into percentage.
The formula for percentage increase would be = increase ÷ original amount × 100
The increase of the cost = 335 - 200 = $135
The original amount = $200
The percentage increase = 135/200 × 100
= 13500/200 = 67.5%
But if the increase in cost is 135 + 50 = $185
The percentage increase of the new cost would be;
= 185/200 ×100
= 18500/200
= 92.5%

7. Sociologists can get three possible answers to a typical survey question such as "Do you believe in the tooth fairy?" - namely, yes, no and no opinion. With this in mind, the Sociomagnetic Computer Company has decided to build a computer to process survey data. This computer has a trinary memory - that is, each byte (tryte?)consists of 8 trits, with a trit holding a 0, 1, or 2. How many trits are needed to hold a 6-bit number? Give an expression for the number of trits needed to hold n bits.
Answer:
1. n ≥ 4
2. N ≥ nlog(2)÷log3
Step-by-step explanation:
1
1 byte = 8 bits
each byte = 8 trits
a 6 bit number = [tex]2^{6} = 64[/tex]
3n ≥ 64
divide through by3
n ≥ 64/3
we take the logarithm
n ≥ [tex]\frac{log64}{log3}[/tex]
n ≥ 1.8062 ÷ 0.4771
n≥3.785
when approximated, n ≥ 4. So the number of trits needed in the storage of 6 bit is atleast 4
2.
to hold n bits, we can do something similar.
3N ≥ 2n
we take log of both sides
such that;
N ≥ [tex]\frac{nlog(2)}{log(3)}[/tex]

The Carousel at Carowinds has 4 rings of horses. Fred is riding on the inner ring, which has a radius of 7 feet. Juan is riding on the outer ring, which is 10 feet farther out from the center than the inner ring is. In one rotation of the carousel, how much farther does Juan travel than Fred? Use 3.14 for .
Answer:
Juan travel 31.4 feet farther than Fred in one rotation.
Step-by-step explanation:
In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:
[tex]s=\theta \cdot r[/tex] (Eq. 1)
Where:
[tex]r[/tex] - Radius, measured in feet.
[tex]\theta[/tex] - Angular arch, measured in radians.
[tex]s[/tex] - Change in linear position, measured in feet.
If both makes one rotation in the carousel, we obtain the change in linear position of each player:
Fred ([tex]r = 7\,ft[/tex], [tex]\theta = 2\pi[/tex])
[tex]s= 2\pi\cdot (7\,ft)[/tex]
[tex]s = (3.14)\cdot (7\,ft)[/tex]
[tex]s = 21.98\,ft[/tex]
Juan ([tex]r = 17\,ft[/tex], [tex]\theta = 2\pi[/tex])
[tex]s= 2\pi\cdot (17\,ft)[/tex]
[tex]s = (3.14)\cdot (17\,ft)[/tex]
[tex]s = 53.38\,ft[/tex]
And the difference between both travelled distances is:
[tex]\Delta s = 53.38\,ft-21.98\,ft[/tex]
[tex]\Delta s = 31.4\,ft[/tex]
Juan travel 31.4 feet farther than Fred in one rotation.

Question 2: A researcher plans to examine what butterfly species are present in one acre of prairie land in Alberta, Canada. The data will be collected as a list of the Latin name for the species. This data can be considered: * qualitative nominal qualitative ordinal quantitative discrete quantitative continuous
Answer:
qualitative nominal
Step-by-step explanation:
The data collected while examining the species of butterflies present in a particular area which are represented using Latin names is a non-numeric data type is aimed at separating or making distinction among the species available. These types of data used in classification are called Qualitative variables.
Also, the data is nominal and not ordinal, this is because there is no sort of order or ranking in the groups or species names. Qualitative variables in which does not posses ordering or ranking in the categories are represented on the nominal scale. Whose which implies order or rank are represented on the ordinal scale.
You own 16 CDs. You want to randomly arrange 5 of them in a CD rack. What is the probability that the rack ends up in alphabetical order?
Answer:
[tex]\frac{1}{524160} or 1.910^{-6}[/tex]
Step-by-step explanation:
In order to solve this, you would need to multiply the probability of you choosing the one that goes first, so 1 in 16 discs, then the next one so 1 in 15, and so on untill the fifth disc.
So you would have to do this:
[tex](\frac{1}{16})(\frac{1}{15})(\frac{1}{14})(\frac{1}{13})(\frac{1}{12})\\\frac{1}{524160}[/tex]
That is the probability that the rack ends up in alphabetical order, if you pull discs randomly, 1 in 524160 chances.
Probabilities are used to determine the chances of an event.
The probability that the rack ends up in alphabetical order is [tex]\mathbf{ \frac{1}{524160}}[/tex]
The given parameters are:
[tex]\mathbf{CD = 16}[/tex]
[tex]\mathbf{r = 5}[/tex] -- CDs to arrange
So, the total number of arrangements of 5 CDs from the 16, is:
[tex]\mathbf{Total = ^{16}P_5}[/tex]
Apply permutation formula
[tex]\mathbf{Total = \frac{16!}{(16 - 5)!}}[/tex]
This gives
[tex]\mathbf{Total = \frac{16!}{11!}}[/tex]
Expand
[tex]\mathbf{Total = \frac{16 \times 15 \times 14 \times 13 \times 12 \times 11!}{11!}}[/tex]
[tex]\mathbf{Total = 16 \times 15 \times 14 \times 13 \times 12 }[/tex]
[tex]\mathbf{Total = 524160}[/tex]
There is only one possibility of the CDs being in alphabetical order.
So, the probability is:
[tex]\mathbf{Pr = \frac{1}{524160}}[/tex]
Hence, the probability that the rack ends up in alphabetical order is [tex]\mathbf{ \frac{1}{524160}}[/tex]

A meteorologist is monitoring the atmospheric pressure as his height above sea level varies. The meteorologist determines that the atmospheric pressure decreases by 12% for each additional kilometer the city is above sea level. The atmospheric pressure at sea level is 103 kPa (kilopascals). Define a function, p , that determines the atmospheric pressure (in kPA) in terms of the number of kilometers the city is above sea level, n .
Answer:
The function [tex]p(n)[/tex] is represented by [tex]p(n) = 103\cdot (0.88)^{n}[/tex].
Step-by-step explanation:
Statement indicates that atmospheric pressure decreases exponentially when height above sea level is increased. This fact is represented by the following model:
[tex]p(n) = p_{o}\cdot r^{n}[/tex] (Eq. 1)
Where:
[tex]p_{o}[/tex] - Atmospheric pressure at sea level, measured in kilopascals.
[tex]r[/tex] -Atmospheric pressure decrease rate, dimensionless.
[tex]n[/tex] - Height above sea level, measured in kilometers.
[tex]p(n)[/tex] - Current pressure, measured in kilopascals.
If we know that [tex]p_{o} = 103\,kPa[/tex] and [tex]r = 0.88[/tex], the function [tex]p(n)[/tex] is represented by:
[tex]p(n) = 103\cdot (0.88)^{n}[/tex]

The scale on a map is 1 :50000.
The area of a field on the map
is 1.2square centimetres.
Calculate the actual area of the field in square kilometres.
Answer:
The actual area of the field in square kilometers is [tex]30000000 km^2[/tex]
Step-by-step explanation:
Scale : 1 cm = 50000 km
Area of field on map = [tex]1.2 cm^2[/tex]
Now , 1 cm = 5000 km
[tex]1 cm^2 = (5000 km)^2[/tex]
We are supposed to find the actual area of the field in square kilometers.
So, the actual area of the field in sq. km =[tex]1.2 \times (5000)^2[/tex]
Actual area of the field in sq. km [tex]=30000000 km^2[/tex]
Hence the actual area of the field in square kilometers is [tex]30000000 km^2[/tex]
