<h2>Answer:</h2>

The factors are <u>(x-3) and (x-3)</u>

<h2>Given: </h2>

$x^{2}-6 x+9$

<h2>Step-by-step explanation:</h2>

In this problem, we need to find the factors which is on multiplying the factor we will get the equation.

$\Rightarrow x^{2}-6 x+9$

Now, we need find the sum of the coefficient of ‘x’ and product of the constant.

The coefficient of ‘x’ is written as:

$\Rightarrow x^{2}-3 x-3 x+9$

Now, we need to find the common multiply and divide the equation into two,

$\Rightarrow x(x-3)-3(x-3)$

$\Rightarrow(x-3)(x-3)$

$\therefore(x-3)^{2}$

Thus, the factor is formed which is multiplied to give the equation given in the question.

Answer:

The probability that an applicant does not get a job if he or she has an interview is 20%.

Step-by-step explanation:

If the applicant has been interviewed, then she/he belongs to the group of 20 people that had an interview.
16 of the 20 people who were interviewed were offered a job, which means that 4 of the 20 people interviewed were not offered a job.
Then, 4/20= 20% of the people who were intervied did not get a job, which means that the <u>probability that an applicant does not get a job if he/she were interviewed is 20%</u>.
Pat attention: this probability results from analysing the probability of getting a job once you have had an interview (this condition restricts our attention to the group of 20 people who had an interview, and not to the hole group of 500 people who did apply for the job).

A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/2 of a barrel of raisins.

balu736 [363]

1/6 = 1 batch, 2/6 = 2 batches and so on

if the factory used 1/2, the factory used 3/6 of a barrel, which equals to 3 batches.

An engineer commutes daily from her suburban home to her midtown office. The average time for a one-way trip is 36 minutes, with

Ivanshal [37]

Answer:

57.93% probability that a trip will take at least 35 minutes.

Step-by-step explanation:

Problems of normally distributed samples are 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.

In this problem, we have that:

$\mu = 36, \sigma = 4.9$
