Bess [88]

Answer:

Complete: (1/2 dominant. + 1/2 recessive.)2

Homozygous. recessive.: 1/2 recessive. x 1/2 rec. = 1/4 rec.-rec.

Homozygous. dominant.: 1/2 dominant. x 1/2 dominant. = 1/4 dom.-dom.

Step-by-step explanation:

First, let us understand what the rule of multiplication is all about:

Basically, the rule of multiplication is a rule that states that there is a probability that two independent parallel event will eventually meet at a point.

Referring back to the question and applying the rule of multiplication,

we have,

Complete: (1/2 dominant + 1/2 recessive.) 2

Homozygous. recessive.: 1/2 rec. x 1/2 rec. = 1/4 recessive.-rec.

Homozygous. dominant.: 1/2 dom. x 1/2 dom. = 1/4 dom.-dom.

A police car leaves a crime scene heading east directly towards the hospital at 72 kilometres per hour. An ambulance leaves a qu
blagie [28]

It will take 2 hours for the ambulance to pass the police car.

Given that a police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour, and an ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour, to determine how long will it take for the ambulance to pass the police car, the following calculation must be performed:

  • 72 x 0.25 = 18
  • 81 - 72 = 9
  • 18/9 = 2
  • 72 x 0.25 + 72 x 2 = 162
  • 81 x 2 = 162

Therefore, it will take 2 hours for the ambulance to pass the police car.
