Answer:

Equivalent: 6(y - 3) AND 2(3y - 9)

Not Equivalent: 3(y - 6) AND 2(y - 9)

Step-by-step explanation:

4y - 2(5 - y + 4)

4y - 2(9 - y)

4y - 18 + 2y

6y - 18 (Everything must be equivalent to this)

3(y - 6) NOT EQUIVALENT

3y - 18

6(y - 3) EQUIVALENT

6y - 18

2(y - 9) NOT EQUIVALENT

2y - 18

2(3y - 9) EQUIVALENT

6y - 18

An airplane has 100 seats for passengers. Assume that the probability that a person holding a ticket appears for the flight is 0
zmey [24]

Answer:

96.33% probability that everyone who appears for the flight will get a seat

Step-by-step explanation:

I am going to use the binomial approximation to the normal to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that \mu = E(X), \sigma = \sqrt{V(X)}.

In this problem, we have that:

n = 105, p = 0.9

So

\mu = E(X) = np = 105*0.9 = 94.5

\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{105*0.9*0.1} = 3.07

What is the probability that everyone who appears for the flight will get a seat

100 or less people appearing to the flight, which is the pvalue of Z when X = 100. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{100 - 94.5}{3.07}

Z = 1.79

Z = 1.79 has a pvalue of 0.9633

96.33% probability that everyone who appears for the flight will get a seat

25,704 ÷ 28 PLS SHOW WORK! ∧
fredd [130]

Answer:

the answer is 918

Step-by-step explanation:

first you would see how many times 257 could go into 28 which is about 9 so you could do 9 times 28 which is 257-252 which is 5. Then bring the 7 down to make 57. Then repeat the first step with every time and you should get 918. (57 goes into 28 once)
