Step-by-step explanation:

If you factor the function, you end up with (x+6)(x+2). The next step is to equal them to 0 to find x for both. The answer would mean x=-6 and x=-2

Find the missing side

Romashka-Z-Leto [24]

Hi there!
The question here is basically asking us to use ratios to find the length of the missing side. To do this, we must first construct a ratio. The best one would be -
$\frac{84}{12} = \frac{56}{x}$
Now, just cross multiply and solve for x.
$\frac{84}{12} = \frac{56}{x}$
$84x = 672$
$x = 8$
Therefore, the length of the missing side would be 8. Hope this helped!

Lady bird [3.3K]

Answer:

a) 56.91% probability that the customer will have to wait between 5 and 10 minutes.

b) 65.49% probability that the client will have to wait less than 6 minutes of more than 9 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:

$\mu = 9.2, \sigma = 2.6$
