I can help you find the last four but you need to graph them. The next four in the sequence is (20, 14), (25, 17), (30, 20), (35, 23). I hope this helps!

Helena is baking a cake that requires three and one-half cups of flour. Helena accidentally poured five and one-sixth cups of fl

RUDIKE [14]

Amount of flour Helena accidentally poured $=5\frac{1}{6} =\frac{31}{6}$ cups of flour.

Amount of flour the cake requires $=3\frac{1}{2} =\frac{7}{2}$ cups of flour.

Amount of flour that Helena should take out $=\frac{31}{6} - \frac{7}{2}$

$=\frac{31}{6} - \frac{7 \times 3}{2\times 3}$

$=\frac{31}{6} - \frac{21}{6}$

$=\frac{31-21}{6}$

$=\frac{10}{6}$

$=\frac{5}{3}$

$=1\frac{2}{3}$ cups of flour.

Answer:

0.13% of customers spend more than 46 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:

$\mu = 40, \sigma = 2$
