Answer:

The graph in the upper left

Step-by-step explanation:

We can answer this question by elimination.

The answer can't be the two graphs on the right, because the two lines will never cross.

It can't be the graph at the lower left, because this shows both cyclists starting at Mile 0.

It must be the graph in the upper left. It shows one cyclist starting 45 mi ahead of the other, with the faster cyclist catching up after about 2.5 h.

Find the indicated area under the curve of the standard normalâ distribution; then convert it to a percentage and fill in the bl

pantera1 [17]

Answer:

68.26%

Step-by-step explanation:

The z score is a measure used in statistic to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then the raw score id below the mean. The z score is calculated using:

$z=\frac{x-\mu}{\sigma}\\ where\ \mu \ is \ the\ mean, \sigma\ is\ the\ standard\ deviation\ and\ x \ is\ the\ raw\ score$

From the normal distribution table, Area between z equal -1 and z equal 1 = P(-1 < z < 1) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 0.6826 = 68.26%

About 68.26% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean).
