Using the binomial distribution, it is found that there is a 0.25 = 25% probability he will land on A on the first spin and A and the second.
For each spin, there are only two possible outcomes, either it lands on Sector A, or it does not. The results of each spin are independent, hence, the binomial distribution is used to solve this question.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, we have that:
- The sectors are equal, which means that it is equally as likely to land on each, hence
.
- Saul will spin the wheel twice, hence
.
The probability that both land on A is P(X = 2), hence:


0.25 = 25% probability he will land on A on the first spin and A and the second.

According to the valence number of copper(2+) and the same value for chlorine (1-) copper (II) chloride has the formula of CuCl2
The molar mass of copper is 0,0635 kg/mole and chlorine gas a molar mass of 0,035 kg/mole the compound will have a molar mass of ( 0,0635+2×0,035 )kg/mole=0,099kg/mole and 0,344 moles are equivalent in mass to 0,344×0,135 kg=0,046 kg
The first question answer is A
The second question answer is B
$10.95 each pizza .. all u do is the subtract 7 and 3 from 64.75 and it would be 54.75. Then just divide that number by 5.
Answer:
864 cm
Step-by-step explanation:
Circunferencia = Distancia (diámetro) × π
Diámetro = 55 cm
Número de vueltas = 5
Circunferencia = π × (55cm × 5)
= 863,93797974 cm
Aproximadamente = 864 cm
