Roberta cites the following statement as evidence for a claim. "the chicken genome has about 17,000 genes, and the grape has about 30,000 genes. " which claim about human genes would be most strongly supported by this statement?.
The assertion that there aren't many extra genes in humans compared to other organisms would be the one this statement would most strongly support.
Genes are stretches of DNA that aid in the precise determination of each trait. The primary biological factor transmitted from parent to child. Genes are composed of DNA sequences and are organised sequentially at specified sites on chromosomes in the cell nucleus.
The human genome project estimates that we contain between 20,000 and 25,000 genes. Daphnia, a microscopic eating flea, contains 31,000 genes, the most of any animal.
Therefore, the claim that there are not particularly many genes in humans compared to other organisms would be most strongly supported by this statement.

The claim that humans have more number of genes than chickens and grapes
The statement provided by Roberta states that the chicken genome has about 17,000 genes, and the grape has about 30,000 genes. This statement indicates that grapes have more genes than chickens. Therefore, it can be inferred that humans have more genes than chickens and grapes, as humans typically have more complex genomes than other species.

Bounce Club surveyed a random sample of 555555 of their members about their favorite type of music. Of the members surveyed, 222222 said that jazz is their favorite type of music. There are 422422422 Bounce Club members. Based on the data, what is the most reasonable estimate for the number of Bounce Club members whose favorite type of music is jazz music
This is calculated by multiplying the proportion of members who said jazz is their favorite type of music (222222/555555) by the total cost number of Bounce Club members (422422422).
1. Calculate the proportion of members who said jazz is their favorite type of music:
222222/555555
= 0.4
2. Multiply the proportion (0.4) by the total number of Bounce Club members (422422422):
0.4 x 422422422
= 400,000
The survey asked 555555 members of the Bounce Club about their favorite type of music and 222222 said that jazz was their favorite type of music the proportion of members who said jazz is their favorite type of music (222222/555555) was multiplied by the total number of Bounce Club members (422422422).

Working together, Frank and Joe could mow both of their yards in a fraction of the time it would take them individually.
Frank can mow his own yard in 45 minutes.
Joe's yard is 40% larger than Frank's.
Therefore, Joe's yard would take 56 minutes (45 x 1.4) to mow.
The combined time for both yards would be 101 minutes (45 + 56).
This can be expressed as 01:15 (1 minute and 15 seconds).
Frank can mow his own yard in 45 minutes. Joe's yard is 40% larger than Frank's, so it would take Joe 56 minutes to mow his yard.

Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9.2 cm}\underline{General equation of an ellipse}\\\\$\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1$\\\\where:\\\phantom{ww}$\bullet$ $(h,k)$ is the center\\ \phantom{ww}$\bullet$ $(h\pm a,k)$ or $(h,k\pm b)$ are the vertices\\ \phantom{ww}$\bullet$ $(h\pm c,k)$ or $(h,k\pm c)$ are the foci where $c^2=a^2-b^2$\\\end{minipage}}[/tex]
Given:
Foci: (3, 1) and (7, 1)Major axis: 10The center of an ellipse is the midpoint of the foci.
Therefore, the center (h, k) of the ellipse is (5, 1), so:
h = 5k = 1The foci are on the major axis of an ellipse.
Given that the y-values of the given foci are the same, the ellipse is horizontal.
The foci of a horizontal ellipse are (h±c, k)
[tex]\implies 5-c=3 \implies c=2[/tex]
[tex]\implies 5+c=7 \implies c=2[/tex]
The major axis of a horizontal ellipse is 2a.
If the major axis is 10, then a = 5.
The vertices of a horizontal ellipse are (h±a, k).
Therefore the coordinates of the vertices are:
(5-5, 1) = (0, 1)(5+5, 1) = (10, 1)The minor axis of a horizontal ellipse is 2b.
As c² = a² - b² then b = √(a² - c²).
[tex]\implies b=\sqrt{5^2-2^2}=\sqrt{21}[/tex]
Therefore, the minor axis is 2√(21).
The eccentricity of the ellipse is:

Using the concept of angle in a straight line and the vertically opposite angles, The answer is x= [tex]7^o[/tex] and z =[tex]105^o[/tex].
What is an angle?An angle is a measure of the amount of rotation between two lines or planes. It is typically measured in degrees or radians. An angle can be defined as the amount of rotation needed to bring one line or plane into coincidence with another. Angles are often represented graphically as a central point, called the vertex, and two rays that extend from the vertex in different directions. The angle is the amount of rotation needed to rotate one ray so that it coincides with the other ray.
What is vertically opposite angle and angle in a straight line?Vertically opposite angles are a pair of angles that are opposite each other and have the same vertex, with the rays of the angles extending in opposite directions. They are formed when two lines intersect at a right angle. For example, in the letter "L" shape, the angles in the corner of the "L" shape are vertically opposite angles. They are congruent angles and supplementary angles, meaning they add up to 180 degrees.
An angle in a straight line is when two lines are in the same straight line and forms an angle of 180 degree. It is also called a straight angle. A straight angle is formed when a line is bent so that its two endpoints are in the same location, creating an angle of 180 degrees. The rays of the angle are in the opposite direction, hence it is also known as straight angle.
75 = 8x+19 (Vertically opposite angles)
75-19 = 8x
x=56/8 = [tex]7^o[/tex].
75+z =180 (Angle in a straight line)

An average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
how to calculate the average(avg) = sum of all terms/number of terms.
According to the question:
Mariella had compared 9 brands later on she wanted to even compare the other 2 brands so the average has to be calculated to 11 brands (9+2).
We can formulate it as (292 +282+ 9*254)/11

To mix paint that is 40% gloss with paint that is 25% gloss to make 5.25 gallons of paint that is 30% gloss, the paint mixer should mix 1.75 gallons of paint that is 40% gloss with 3.5 gallons of paint that is 25% gloss.
Let x be the number of gallons of paint that is 40% gloss and y be the number of gallons of paint that is 25% gloss. To mix paint that is 40% gloss with paint that is 25% gloss to make 5.25 gallons of paint that is 30% gloss, we can set up the following system of equations:
0.40x + 0.25y = 0.30 × 5.25
x + y = 5.25
To solve this system of equations, we can first multiply the second equation by 0.4 to eliminate the x term, and then we can subtract the first equation from the resulting equation to solve for y:
0.4x + 0.25y = 0.3×5.25
0.4x + 0.4y = 0.4×5.25
0.15y = 0.1×5.25 = 0.525
y = 0.525/ 0.15
y = 3.5
Then we can substitute this value of y back into one of the original equations to solve for x:
x = 5.25 - y
x = 5.25 - 3.5
x = 1.75
Therefore, the paint mixer should mix 1.75 gallons of paint that is 40% gloss with 3.5 gallons of paint that is 25% gloss to make 5.25 gallons of paint that is 30% gloss.
