2. If you pay a one-time fee of $30, you can

VikaD [51]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

One time fee = $30

Reduced price of ticket after one time fee payment = $17

Regular ticket cost = $25

Write an inequality that can be used to determine the number of reduced price concert tickets you would need to purchase in order for the total cost to be less expensive than the same number of regular tickets

Let the number of tickets needed to purchase = t

Reduced ticket = 30 + 17t

Regular ticket = 25t

30 + 17t < 25t

30 < 25t - 17t

30 < 8t

30/8 < 8t/8

3.75 < t

t > 3.75

Hence number of ticket must be greater than 3.75

t = 4

If you plotted these elevations on a vertical number

Vlad [161]

Answer:

The correct option is C

C) Hungary

Step-by-step explanation:

Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.

Answer:

1. False; 2. False; 3. False.

Step-by-step explanation:

1. Mode

False.

The mode, mean, and media are all measures of central tendency.

The mean is the best measure for normally distributed data.

The median is the best measure for skewed data.

The mode is the least used, because it's the only measure you can apply to nominal data.

2. Median

False.

The mean is the average of a set of scores or list of numbers.

3. Frequency distribution table

False.

It is not necessary to put the numbers in order.

For example, assume that you wanted to count the frequency of occurrence of each number in the list: 3, 0, 1, 4, 4, 1, 2, 0, 2, 2, 0, 2, 0, 1, 3, 1, 2, 1, 1, 3.

If you are doing this manually, you would go through the list and use tally marks to record the appearance of each number in its category.

If you are using a computer, it will do the sorting for you.
