4 0

Just before colliding with another vehicle, you should take your foot off the brake pedal.
 There are several things you can do in order to minimize the consequences of collisions. One of them is to take your foot off the brake pedal. Other are:
- If possible, swerve to the right side of the road when you take evasive action.
- Another general rule is to hit an object with a glancing blow (at an angle) rather than head-on.

Prepare a Pareto chart of the possible causes for a student to fail a final examination in a university course.

Hitman42 [59]

Answer:

Option 1

$\bar x_1 = 96.2$

$Mode = 99$

$\sigma_1 = 3.22$

Option 2

$\bar x_2 = 97.4$

$Mode = 97$

$\sigma_2 = 0.499$

Explanation:

Given

$Option\ 1: 99, 98, 99, 94, 92, 99, 98, 99, 94, 90$

$Option\ 2: 98, 97, 97, 97, 98, 98, 97, 97, 98$

Required

The mean, mode and standard deviation of both options

Option 1

Calculate mean

$\bar x = \frac{\sum x}{n}$

$\bar x_1 = \frac{99+ 98+ 99+ 94+ 92+ 99+ 98+ 99+ 94+ 90}{10}$

$\bar x_1 = \frac{962}{10}$

$\bar x_1 = 96.2$

Calculate mode

$Mode = 99$

Because it has a frequency of 4 (more than other element of the dataset)

Calculate standard deviation

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

$\sigma_1 = \sqrt{\frac{(99-96.2)^2 +.............+(90-96.2)^2}{10}}$

$\sigma_1 = \sqrt{\frac{103.6}{10}}$

$\sigma_1 = \sqrt{10.36}$

$\sigma_1 = 3.22$

Option 2

Calculate mean

$\bar x = \frac{\sum x}{n}$

$\bar x_2 = \frac{98+ 97+ 97+ 97+ 98+ 98+ 97+ 97+ 98}{9}$

$\bar x_2 = \frac{877}{9}$

$\bar x_2 = 97.4$

Calculate mode

$Mode = 97$

Because it has a frequency of 5 (more than other element of the dataset)

Calculate standard deviation

$\sigma_2 = \sqrt{\frac{(98-97.4)^2+..............+ (98-97.4)^2}{9}}$

$\sigma_2 = \sqrt{\frac{2.24}{9}}$

$\sigma_2 = \sqrt{0.2489}$

$\sigma_2 = 0.499$

Incubators

Explanation:

In north american context the incubators refers to small places for business provided on low rent.

Basically in the given context, the space for new shops for businesses is given by state and city government, this clearly states that because of involvement of government the prices of such place would be really low as compare to private rental spaces.

This provides that because of this facility incubators will grow.
