Given,
In the question:
If transcription progresses at the rate of 40 nucleotides per second.
To find the how long it would take to transcribe a sequence that is 3. 6 x 104 bases long?
Why is a nucleotide necessary?
Nucleotides have a variety of roles in animal physiology, including those of energy storage, transporters of activated metabolites for biosynthesis, structural moieties of coenzymes, and metabolic regulators.
Give an example of nucleotides and describe them.
A nucleotide is the fundamental part of nucleic acids (RNA and DNA). A nucleotide is made up of a nitrogen-containing base, a phosphate group, and a sugar molecule (either ribose in RNA or deoxyribose in DNA). The nucleotides used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Hence, 20 to 25 minutes Transcription occurs at a rate of 40 nucleotides per second.

a wheat farmer is investigating the effectiveness of a treatment for controlling a pest. a random sample of 500 plants shows that 47 of them are infected by the pest. what does this sample indicate about the claim that 20% of the plants are infected?
The sample indicates that the data does not provide sufficient evidence to support the claim that 20% of plants are infected.
This given test is a test for single sample proportion
The test hypothesis are:
[tex]H_{o} :p=0.20[/tex], null hypothesis
[tex]H_{1} :p\neq 0.20[/tex], alternative hypothesis
The test statistic fallows a standard normal distribution and is given by:
[tex]Z=\frac{x-p}{{\sqrt{p(1-p)/n} } }[/tex]
p=0.20
X=47 plants
Sample size, n=500
x, is the sample mean:
x=X/n=47/500
x=0.094
So, test statistic is calculated as:
[tex]Z=\frac{0.094-0.20}{\sqrt{0.20(1-0.20)/500} }[/tex]
Z=-5.93
From the z-table, the p-value associated with Z=-5.93 is approximately 0
The decision rule based on p-vale, is to reject the null hypothesis if p-value is less than confidence level
In this case, the p-value is very small and less than confidence level of 0.20, we therefore reject the null hypothesis or the claim
So we conclude that the data does not provide sufficient evidence to support the claim that 20% of plants are infected.

What are the coordinates of the point on the directed line segment from (-9, -10)
to (1,5) that partitions the segment into a ratio of 2 to 3?
The coordinates of the point on the directed line segment from (-9, -10) to (1,5) that partitions the segment into a ratio of 2 to 3 is (-5,-4)
The end points of the line segment = (-9, -10) and (1, 5)
The partition ratio = 2 : 3
According to the partition rule
The x coordinate of the point = [tex]x_1+\frac{A(x_2-x_1)}{A+B}[/tex]
A = 2
B = 3
Substitute the values in the equation
The x coordinate of the point = -9 + [2(1--9) / 2+3]
= -9 + [2×10 / 5]
= -9 + [20/5]
= -9 + 4
= -5
Similarly,
The y coordinate of the point = [tex]y_1+\frac{A(y_2-y_1)}{A+B}[/tex]
= -10+[2(5--10)/2+3]
= -10+[2×15/5]
= -10+[30/5]
= -10 + 6
= -4
Hence, the coordinates of the point on the directed line segment from (-9, -10) to (1,5) that partitions the segment into a ratio of 2 to 3 is (-5,-4)

A car moves at a speed of 80km/h from P at 0800 hours and reaches Q at 0930 hours. A lorry takes the same route from Q at 0800 hours to P at a speed of 70km/h. At what time do both vehicles meet?
The vehicles will meet at 0845 at a distance of 64 km from P when they move at the respective speeds.
The car moves at a speed of 80km/h from P to Q and it takes time t
t = 9.30 - 8.00 = 1 hour 30 minutes or 1.5 hours
Distance covered = speed × time
Distance = 80 × 1.5 = 120 km
Now et the cars meets at a distance of x km from P.
times taken by the car to cover x km = x/80 hours
The lorry travels 120 - x in that same time.
time taken = 70/(120 - x)
Now the time taken must be equal.
Therefore we will form an equation to calculate x.
(120 - x) / 70 = x / 80
or, 960 - 8x = 7x
or, 15x = 960
or, x = 64
Therefore the cars will meet at 64 km from P.
Now time taken by the car to cover 64 km = 64/80 = 0.8 hours = 48 minutes
Hence the cars will meet at 0845 hours.

A retailer needs to purchase 12 printers. The first printer costs $54, and each additional printer costs 5% less than the price of the previous printer, up to 15 printers. What is the total cost of 12 printers?.
The total cost of 12 printers is; $493.41
Cost of first printer; C1 = $54
Cost of second printer is; 95% × 54 = $51.3
Cost of third printer is; 0.95 × 51.3 = $48.735
Cost of fourth printer = 0.95 × 48.735 = $46.298
Now, let us apply same pattern using a calculator for the remaining costs and we will have them as follows;
Cost of 5th printer = $43.983
Cost of 6th printer = $41.784
Cost of 7th printer = $39.695
Cost of 8th printer = $37.710
Cost of 9th printer = $35.825
Cost of 10th printer = $34.033

STATISTICS The most familiar statistical measure is the arithmetic mean, or average. A second important statistical measure is the standard deviation, which is a measure of how far the individual scores are from the mean. For example, the mean score on the Wechsler IQ test is 100 and the standard deviation is 15. This means that people within one deviation of the mean have IQ scores that are 15 points higher or lower than the mean.
An absolute value equation that can be used to find the maximum and minimum scores within one standard deviation of the mean is |x - 20.9| = 5.3.
The minimum score that is within one standard deviation of the mean is equal to 15.6.
What is an absolute value function?In Mathematics, an absolute value function can be defined as a type of function that consist of an algebraic expression, which is placed within absolute value symbols and measures the distance of a point on the x-coordinate to the x-origin (0).
Mathematically, an absolute value function can be represented by this mathematical expression:
|x| = x, x ≥ 0.|x| = x, x < 0.Since the standard deviation is 5.3 and the mean is 20.9, an absolute value equation for the scores that is within one standard deviation of the mean is given by:
|x - 20.9| = 5.3.
x - 20.9 = ±5.3
Evaluating the absolute value function, the maximum score is given by:
x - 20.9 = 5.3
x = 20.9 + 5.3
x = 26.2.
Evaluating the absolute value function, the minimum score is given by:
x - 20.9 = -5.3
x = 20.9 - 5.3
x = 15.6.

A sampling distribution is a probability distribution of a statistic that is derived from a bigger sample size of individuals chosen at random from a given population. The sampling distribution of a particular population is the distribution of frequencies of a variety of potential outcomes for a population statistic.

suppose weights of the checked baggage of airline passengers follow a nearly normal distribution with mean 45 pounds and standard deviation 3.2 pounds. most airlines charge a fee for baggage that weigh in excess of 50 pounds. determine what percent of airline passengers incur this fee.
In most of the cases airlines charges a fees for baggage weigh in excess of 50 pounds. Then about 94.06% passengers incur this fees.
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Given That,
Mean (μ) = 45 pounds and Standard Deviation (σ) = 3.2
This means that μ = 46 , σ = 3.2
Since, Most airlines charges a fee for baggage that weigh in excess of 50 pound.
Then, As a proportion this is 1 subtracted by the P - value of Z when
X =50. So,
Z = X - μ / σ
⇒ Z = 50 -45/ 3.2
⇒ Z = 5/3.2
⇒ Z = 1.56
when Z = 1.56 has a P- value of 0.9406
Now, 0.9406 × 100%
= 94.06%
Therefor, 94.06% of airline passengers incur this fees.

Step-by-step explanation:
y=mx+b
Convert the given values f(-10) = 4, f (8) = -5 to coordinates (-10,4) (8,-5)
Hence we use the formula for finding the slope m:
[tex]\displaystyle\\\boxed{m=\frac{y_2-y_1}{x_2-x_1} }\\\\x_1=-1\ \ \ \ \ x_2=8\ \ \ \ \ \ y_1=4\ \ \ \ \ y_2=-5\\\\m=\frac{-5-4}{8-(-10)}\\\\m=\frac{-9}{8+10} \\\\m=\frac{-9}{18} \\\\m=-0.5\\\\Thus, y=-0.5x+b\ \ \ \ (1)\\\\[/tex]
