Help with question 13

The average length of DNA per gene would be 40,000 base pairs if the genome had 20,000 genes.

Average gene length: just 2.5% of the human genome codes for proteins. The remaining 97.5% are introns. The male nuclear diploid genome measures 205.00 centimeters (cm), is 6.27 Gigabase pairs (Gbp), and weighs 6.41 picograms (pg). 208.23 cm, 6.51 pg, and 6.37 Gbp are the female measurements. "The overall number of base pairs, which is the length of DNA per gene, will be roughly twice the number of genes present in the genome, in this example 40,000, for a 25% mammalian genome with 20,000 genes".

A DNA region from which an mRNA is transcribed is the de facto definition of a "gene" in mammalian genome annotation. Because one cannot deduce function from a genome sequence alone, the correct functional genetic definition of a gene—a segment of DNA that can complement a mutant phenotype—is lost.

Answer:

Priya:  S=20w+50

Vanessa:  S=25w+20

6 weeks

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Define the variables:

Given that Priya starts with $50 in her bank account, the y-intercept of the linear equation modelling her savings will be 50.

If she then deposits $20 each week for 12 weeks, the slope will be 20.

Therefore, the linear equation that models Priya's savings is:

Given that Vanessa starts with $20 in her bank account, the y-intercept of the linear equation modelling her savings will be 20.

If she then deposits $25 each week for 12 weeks, the slope will be 25.

Therefore, the linear equation that models Vanessa's savings is:

Create a table for each linear equation from part a.

Priya                       Vanessa

[tex]\begin{array}{|c|c|}\cline{1-2} w & S \\\cline{1-2} 1&70 \\\cline{1-2} 2& 90\\\cline{1-2} 3&110 \\\cline{1-2} 4&130 \\\cline{1-2} 5& 150\\\cline{1-2} 6&170 \\\cline{1-2} 7&190 \\\cline{1-2} 8&210 \\\cline{1-2} 9&230 \\\cline{1-2} 10&250 \\\cline{1-2} 11& 270\\\cline{1-2} 12& 290\\\cline{1-2} \end{aligned}[/tex]               [tex]\begin{array}{|c|c|}\cline{1-2} w & S \\\cline{1-2} 1&45 \\\cline{1-2} 2& 70\\\cline{1-2} 3& 95\\\cline{1-2} 4& 120\\\cline{1-2} 5& 145\\\cline{1-2} 6& 170\\\cline{1-2} 7& 195\\\cline{1-2} 8& 220\\\cline{1-2} 9& 245\\\cline{1-2} 10& 270\\\cline{1-2} 11& 295\\\cline{1-2} 12&320 \\\cline{1-2} \end{aligned}[/tex]

Create a graph for each linear equation (see attachment).

The week in which Priya and Vanessa will have the same amount of savings is the week where the S-values in the tables are the same, and the point of intersection of the graphed lines.

Therefore, from inspection of the tables and graphs from part b, Priya and Vanessa will have the same amount of savings in week 6.

AC bisects angle BAD and AC bisects angle BCD is proved using CPCT rule.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Given that, ΔABC≅ΔADC.

We know that, corresponding parts of congruent triangle are equal.

So, ∠BAC=∠DAC (∵CPCT)

∠BCA=∠DCA (∵CPCT)

∠BAD=∠BAC+∠DAC

⇒ ∠BAD=2∠BAC

⇒ ∠BAC=∠BAD/2

So, AC bisects ∠BAD

∠BCD=∠BCA+∠DCA

⇒ ∠BCD=2∠BCA

⇒ ∠BCD/2=∠BCA

So, AC bisects ∠BCD

Hence, proved AC bisects ∠BAD and AC bisects ∠BCD.

The graph of the function f(x) = [x² if x ≤ 2] [x + 4 if x > 2]

From the question, we have the following parameters that can be used in our computation:

f(x) = [x² if x ≤ 2] [x + 4 if x > 2]

The above function is a piecewise function, and it can be split as follows:

f(x) = [x² if x ≤ 2]

f(x) = [x + 4 if x > 2]

The domain x ≤ 2 in f(x) = [x² if x ≤ 2]  means that:

The x values stop at 2 (i.e. 2 inclusive)

The domain x > 2 in f(x) = [x + 4 if x > 2] means that:

The x values starts at a value greater than 2 (i.e. 2 exclusive)

Answer:

Step-by-step explanation:

The p-value is 0.15 which is greater than the significance value 0.10 so null hypothesis cannot be rejected at 10% significance level , we do not have enough evidences to state that no- show rate is less than 6%.

As given in the question,

Null hypothesis : No show rate for passengers booked on given flight is 6%

Alternative hypothesis: No show rate  for passengers booked on given flight  is less than the 6%

P = 6%

  = 0.06

1 -  P = 1 - 0.06

       = 0.94

random sample size 'n' = 380

no shows = 18

Sample proportion 'p' = 18/ 380

                                    = 0.047

Now , z test statistic value :

z = (p - P)/ √P (1- P)/n

 = (0.047 - 0.06)/√0.06( 0.94)/380

 = -0.013 /0.012

 = -1.083

p-value = 0.2788 ( using table)

0.2788 > 0.10

p-value is greater than significance value 0.10

Do not reject null hypothesis at 10% level of significance.

Therefore, as p-value is greater than significance value do not have enough evidences to state that no- show rate is less than 6%.

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

Answer:

To calculate Nora's total annual interest on her $800 investment, we can use the following formula:

Interest = Principal x Rate x Time

In this case, the principal is $800, the rate is 6% per annum, and the time is 1 year. Plugging these values into the formula, we get:

Interest = $800 x 0.06 x 1

To convert the 6% rate to a decimal, we divide 6 by 100. This gives us 0.06. We then multiply the principal by the rate and the time to get the total annual interest. So the total annual interest on Nora's $800 investment is:

Interest = $800 x 0.06 x 1 = $48

Therefore, Nora will earn a total of $48 in interest on her $800 investment over the course of one year at a rate of 6% per annum.

The 64th term of the arithmetic sequence -3, -14 -25, will be - 696.

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

Given that;

The arithmetic sequence is,

⇒ -3, -14 -25.

Now,

Since, We know that;

⇒ nth term = a + (n - 1)d

Where, 'a' is first term, 'd' is common difference.

Here, The arithmetic sequence is,

⇒ -3, -14 -25.

First term (a) = - 3

Common difference (d) = - 14 - (-3)

                                    = - 14 + 3

                                    = - 11

So, We get;

⇒ 64th term = - 3 + (64 - 1) (-11)

                    = - 3 + 63 × - 11

                    = - 3 - 693

The height of the house is approximately 29.43 meters.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

We can use the tangent function to solve this problem.

The tangent of an angle is equal to the opposite side (the height of the house) divided by the adjacent side (the distance between the house and the building). In this case, the angle is 30 degrees and the opposite side is the height of the house, so we can write the following equation:

tan(30°) = height of house / 25√3

We can use a calculator or look up the value of tangent 30° to find that tangent 30 is approximately 0.577. Therefore, the equation becomes:

0.577 = height of house / 25√3

Multiplying both sides of the equation by 25√3 gives us:

height of house = 0.577 × 25√3

Plugging in the values and simplifying, we get:

height of house = 29.43 m

Therefore, the house's height is approximately 29.43 meters.
