The genotype must be Rr and rr because the outcome is close to the 1:1 ratio of red to white flowering plants.

According to Mendel's law of dominance, one feature in a heterozygote will mask the existence of another trait for the same attribute. The dominant allele will be exclusively expressed, as opposed to both alleles contributing to a trait.

When parents with distinct, opposing qualities are crossed, only one form of the trait manifests itself in the offspring, according to Mendel's law of dominance. Only the dominant phenotypic characteristic will be present in the hybrid offspring. The first law of inheritance is the dominance principle.

This regulation states that the first generation of offspring from purebred parents shall exhibit solely dominant features.

There will be a 1:1 ratio between the dominant and recessive traits when a heterozygous dominant parent mates with a pure recessive parent.

The cross:

           r            r

R         Rr          Rr

r          rr           rr

The genotype must be Rr and rr since the outcome is close to the ratio of red to white flowering plants.

Therefore, the correct answer is option A. The result is close to the 1:1 ratio of red to white flowering plants, so the genotype must be Rr and rr.

The complete question is:

A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain

A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the Rr and ir

B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the genotype of each parent is Rr. The number of offspring was not large enough to produce the expected results

C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.

D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.

The work done by the force of friction is μmgd.

The work done by the applied force is equal to the displacement of the block (d) multiplied by the component of the force parallel to the displacement. If the applied force is F and the angle between the force and the displacement is θ, then the component of the force parallel to the displacement is Fcos(θ).

Therefore, the work done by the applied force is given by dFcos(θ). The force of friction will also do work, which is equal to the displacement of the block multiplied by the force of friction. The force of friction is given by μN, where N is the normal force and is equal to the weight of the block (mg). Therefore, the work done by the force of friction is μmgd, where d is the displacement.

The little cubes can be possible to remove in number of 18 cubes maximum.

What is cube ?

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross. The cube is the only regular hexahedron and is one of the five Platonic solids.

The original surface area is (3x3) x 6 = 54 units.

A unit cube has 6 units of area, so we need 9 cubes.

Remove all the cubes except the original eight corners and the center cube.

The 3×3×3 cube has a surface area of 6×3×3 square units. Taking the 27 smaller units and connecting them to form a single entity, the maximum exposed surface area per cube is 6 square units. If nine of these are connected vertex to vertex in any shape then the objective is achieved. So a maximum of 18 of the small cubes can be removed.

Therefore, the starting value of the house was £724,492.37 (rounded to two decimal places).

A fraction is a mathematical expression that represents a part of a whole. It is expressed as two numbers separated by a line or a slash, with the number on top called the numerator and the number on the bottom called the denominator. The numerator represents the number of parts being considered, while the denominator represents the total number of parts in the whole. Fractions can be used to represent quantities such as lengths, distances, time, weight, and many other things in the real world. They are an important concept in mathematics and are used in a wide range of applications, from basic arithmetic to advanced calculus and beyond.

If three bulbs are randomly selected, the probability that a) exactly 2 are 23 watts is 0.136, the probability that b) all are of the same type is 0.542 and c) there will be one bulb of each type is 0.244.

Here we have been given that out of 23 bulbs,

8 are 13 watt

9 are 18 watt

6 are 23 watt

now if three bulbs are randomly selected out of these, it can be done in

²³C₃ ways

a)

There are 6, 23 watts, and 17 bulbs that are not 23 watts.

Hence they can be chosen in

⁶C₂ X ¹⁷C₁ ways

Therefore the probability to get exactly 2 23 watt bulbs is

[⁶C₂ X ¹⁷C₁]/²³C₃

= [6 X 5 X 17 X 3 X 2]/[2 X 23 X 22 X 21]

= [3 X 5 X 17]/[23 X 11 X 7]

= 240/1771

= 0.136

b)

The probability that all three bulbs are of the same type will have three cases. Hence they can be selected in

⁸C₃ + ⁹C₃ + ⁶C₃ ways

Hence the probability will be

[⁸C₃ + ⁹C₃ + ⁶C₃]/²³C₃

= [(8 X 7 X 6) + (9 X 8 X 7) + (6 X 5 X 4)](3 X 2)/[23 X 22 X 21]

=  [(8 X 7 X 6) + (9 X 8 X 7) + (6 X 5 X 4)]/[23 X 11 X 7]

= [336 + 504 + 120]/1771

= 960/1771

= 0.542

c)

The probability to select one bulb of each type will be

[8 X 9 X 6]/²³C₃

= [8 X 9 X 6]/[23 X 11 X 7]

= 432/1771

= 0.244

d) Now if at least 6 bulbs need to be examined, hence

the probability will be 1 - probability that we need to check (1, 2, 3, 4, 5)

= 1 - (¹⁷C₀/23 + ¹⁷C₁/²³C₂ + ¹⁷C₂/²³C₃ + ¹⁷C₃/²³C₄ + ¹⁷C₄/²³C₅)
