For the purposes of addition, subtracting, and comparing fractions, it is appropriate to convert both fractions to a common (equal, same) denominator. LCM(7, 7) = 7, which is the least common multiple of both denominators, can be used to calculate the common denominator. Adding the denominators together yields the common denominator, which need not be the lowest: 7 x 7 = 49. It cannot further simplify the fraction result by cancelling in the next intermediate step.

The four integers are 5, 5, 12 and 14.

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.

When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.

Given:

Mean= 9

Median = 8.5

Mode = 5

Range = 9.

let the numbers arranged in ascending order are a,b,c,d

Median: b+ c /2 = 8.5

b+ c = 17 (number in the middle)

Mode: a = 5, b= 5 {because mode is the most repeating data}

Range: d- a = 9 (last one minus first one)

The volume of the pyramid is 400 cubic units.

A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

We have,

Let's call the height of the pyramid "h".

We can use the Pythagorean theorem to find the slant height of the pyramid, which is the length of one of the edges from the apex to a corner of the base.

To do this, we can consider one of the right triangles formed by the apex, the midpoint of a side, and a corner of the base.

The hypotenuse of this right triangle is the segment connecting the apex to the midpoint of a side, which has a length of 13 units.

One leg of the right triangle is half of one side of the square base, which is 5 units.

The other leg of the right triangle is the height of the pyramid, which we want to find. So, we can write:

h² + 5² = 13²

Simplifying and solving for h, we get:

h²= 13² - 5²

h² = 169 - 25

h² = 144

h = 12

So, the height of the pyramid is 12 units.

To find the volume of the pyramid, we can use the formula:

Volume = (1/3) x Base Area x Height

The base of the pyramid is a square with sides of length 10 units, so its area is:

Base Area = 10² = 100 square units

Plugging in the values we know, we get:

Volume = (1/3) x 100 x 12

Volume = 400 cubic units

Therefore,

The volume of the pyramid is 400 cubic units.

There were 3.75g of sodium in the beans Kelley used and the estimated value for the sodium is 4g

weight of sodium in 1 cup of beans = 0.75

weight of sodium in 5 cups of beans = 0.75 × 5 = 3.75

estimate for the sodium used = 0.8g

therefore, ratio of the actual weight of sodium and the estimated value is

ratio = [tex]\frac{0.75}{0.8}[/tex]

lets assume ratio is x then,

[tex]\frac{3.75}{x}[/tex]   =  [tex]\frac{0.75}{0.8}[/tex]

x = 3.75 × [tex]\frac{0.8}{0.75}[/tex]

x = [tex]\frac{3.75}{0.75}[/tex] × 0.8

x = [tex]\frac{375}{75}[/tex] × 0.8

Two events each have probability 0.2 of occurring. the probability that neither occur is 0.6. these events are: Mutually Exclusive Events. Thus, option C is correct.

Probability is the mathematical study of outcomes in uncertain situation. It is used to describe the likelihood of an event occurring and it can be expressed as number between 0 to 1. Probability is used to quantify the uncertainty associated with any given event it helps us understand how likely it is that something will happen and it can be used to predict future.

The two events in question are independent of one another, meaning that the occurrence of one event does not affect the probability of the other occurring. This means that the probability of neither event occurring is the product of the two probabilities, Therefore these events are Mutually Exclusive Events.

The frequency of the b1 allele after selection genotype frequency = 0.36

Genes can change into a variety of forms, with each form having a slightly different basic DNA sequence. These gene variations differ in the manner in which the trait is manifested, but they nonetheless code for the same feature (hair color) (i.e. brown vs blonde hair). Alleles are various variations of a single gene.

A genotype is a numerical representation of the type of mutation found at a particular locus (i.e., region) in the genome. It can be represented symbolically. As an example, the letters BB, Bb, and bb could be used to indicate a certain gene variant.

The probability that the person reaches 10 before he reaches -5 is 0.475.

The probability of reaching 10 before reaching -5 in a random walk can be found using the concept of expected number of steps to reach a state. In this case, we can calculate the expected number of steps required to reach 10 and -5, and then compare the results.

E10 = 1 + 1/2 × E10 + 1/2 × E9

E9 = 1 + 1/2 × E10 + 1/2 × E8

Substituting the expression for E9 into the equation for E10, we get:

E10 = 1 + 1/2 × E10 + 1/2 × (1 + 1/2 × E10 + 1/2 × E8)

E10 = 1 + 3/4 × E10 + 1/4 × E8

Eliminating E10, we get:

E8 = 4 × (E10 - 1)

Substituting the expression for E8 into the equation for E10, we get:

E10 = 1 + 3/4 × E10 + 1/4 × 4 × (E10 - 1)

E10 = 20

So the expected number of steps to reach 10 is 20.

E-5 = 1 + 1/2 × E-4 + 1/2 × E-5

E-4 = 1 + 1/2 × E-5 + 1/2 × E-3

Substituting the expression for E-4 into the equation for E-5, we get:

E-5 = 1 + 1/2 × (1 + 1/2 × E-5 + 1/2 × E-3) + 1/2 × E-5

E-5 = 1 + 3/4 × E-5 + 1/4 * E-3

Eliminating E-5, we get:

E-3 = 4 × (E-5 - 1)

Substituting the expression for E-3 into the equation for E-5, we get:

E-5 = 1 + 3/4 × E-5 + 1/4 × 4 × (E-5 - 1)

E-5 = 26

So the expected number of steps to reach -5 is 26.

The probability of reaching 10 before reaching -5 is calculated by dividing the expected number of steps required to reach 9 (E9) by the expected number of steps required to reach 10 (E10). The reason for this is that the person will reach 9 after taking 19 steps, which is one step short of reaching 10. Hence, we can consider reaching 9 as an intermediate milestone before reaching 10.

P(10 before -5) = E9 / E10

Since the person has a 1/2 probability of moving one step in either direction, the expected number of steps required to reach 9 (E9) is given by:

E9 = 1 + 1/2 * E10 + 1/2 * E8

E9 = 1 + 1/2 * 20 + 1/2 * E8

E9 = 19/2

So, the probability of reaching 10 before reaching -5 is given by:

P(10 before -5) = E9 / E10

P(10 before -5) = 19/2 / 20

P(10 before -5) = 19/40

P(10 before -5) = 0.475

These three requirements, which are group axioms, are valid for number systems as well as numerous other mathematical structures. For instance, the integer set and addition operation are two examples of groups. Consequently, a group is a mix of a set and a binary operation, to put it simply.

Equivalent ratios are ratios that have the same value, but may have different numerator and denominator values. They are related to each other by multiplication or division of both the numerator and denominator by the same non-zero value.

For example, the ratios 2/4 and 1/2 are equivalent ratios because both represent the same fraction (1/2) and therefore have the same value.

In the diagram, one line is transversal of two parallel lines, so the value of a is 113°, value of b is 67° and value of c is 67°.

On a plane, lines that are parallel to one another never cross or come together. They are always parallel and equally spaced apart from one another. Parallel lines are lines that do not intersect. Lines are referred to as parallel if they never intersect and do not have a common intersection.

One line crosses two parallel lines in the diagram.

Angle an is the 113°'s vertically opposite angle.

Therefore, the angle's value is 113°.

Here, a and b have the same side interior angles since a line is transversal to two parallel lines.

So, a + b = 180°

⇒ 113° + b = 180°

⇒ b = 180° - 113°

⇒ b = 67°

And c is vertically opposite angle of b

So, the value of angle c = 67°

Given the side adjacent to an angle is 25 and the tangent of the angle is 1/5, you want to know the tangent of an angle with the same opposite side, but an adjacent side of 10.

The tangent of an angle is the ratio of the opposite side to the adjacent side.

  Tan = Opposite/Adjacent

Then the Opposite side is ...

  Opposite = Adjacent · Tan(x) = 25·1/5 = 5

For angle y, the opposite side is the same, but the adjacent side is only 10:

  Tan(y) = Opposite/Adjacent = 5/10

1968 of the $10 dollar ticket were sold by jazz & 6873  of the $20 dollar ticket were sold by jazz.

Jazz total amount received = $157,437

Total tickets sold = 8,856

Let the $10 tickets sold = x

The $20  tickets sold = 8,856 - x

Here the solution below :

$10(x) + 8,856 - x($20) = $157,437

$10x + $177120 - $20x = $157,437

-$10x = $157,437 - $177120

-$10x = - $19683

x = 1968.3
