Suppose 10% of the flights arriving at an airport arrive early, 60% arrive on time, and 30% arrive late. Valerie used the random

-number table to find the experimental probability that of 5 flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1, 2, 3, 4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving late. Find the experimental probability that of 5 flights, at least 2 will arrive late. three-tenths two over five nine over twenty eleven over twenty

First, we need to have a random number table.
Next, we randomly choose numbers from the table and consider the first five digits.
After, the corresponding flight arrival is determined based on the given rules in the problem.
Then, the probability that at least 2 will arrive late is determined by taking the average.

An aptitude test is designed to measure leadership abilities of the test subjects. Suppose that the scores on the test are norma
Komok [63]

Using the normal distribution, it is found that 0.0329 = 3.29% of the population are considered to be potential leaders.

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X.

In this problem:

  • The mean is of 550, hence \mu = 550.
  • The standard deviation is of 125, hence \sigma = 125.

The proportion of the population considered to be potential leaders is <u>1 subtracted by the p-value of Z when X = 780</u>, hence:

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

Z = \frac{780 - 550}{125}

Z = 1.84

Z = 1.84 has a p-value of 0.9671.

1 - 0.9671 = 0.0329

0.0329 = 3.29% of the population are considered to be potential leaders.

Oliga [24]

Answer:

128

Step-by-step explanation:

Split the shape into a triangle and a rectangle.

The base of the triangle is 12 cm.

The height of the triangle is the height of the whole shape minus the height of the rectangle, which is: 14-11=3.

We know that the formula for the area of a triangle is 0.5xbxh

Therefore, the area of the triangle is 0.5x12x3 = 18.

NOW, lets work out the area of the rectangle.

The formula for the area of the rectangle is bxh.

= 11*10

= 110.

Now you add the area of the triangle to the area of the rectangle

18+110.

= 128.
