Of 7<br> Express in the form n : 1.<br> Give n as a fully simplified fraction.<br> 6:14

hjlf

Answer:

The ratio is;

3/7 : 1

Step-by-step explanation:

Here, we want to express the given ratio in the form n:1 where n is a fully simplified fraction

Mathematically, we have this by dividing both numbers by 14

That would be ;

6/14 : 14/14

= 3/7 : 1

Discuss circumstances under which it is preferable to use relative frequency distributions instead of frequency distributions?

Mrac [35]

Answer:

The relative frequency distributions would be more preferable to use when we want to measure the weight of a particular category or also when we want to compare different categories of data within a table. Moreover, relative frequency is often used for the probability calculations.

Step-by-step explanation:

Frequency distribution:

A frequency distribution simply tells us how many times an event has occurred or in other words, it is the rate of occurrence.

Relative frequency distribution:

On the other hand, the relative frequency tells us the fraction of how many times an event has occurred with respect to the total number of trials.

For example:

Consider a bag of marbles having marbles of different colors. We randomly pick marbles from the bag and got the following results.

Event | Frequency

Red | 2

Blue | 4

Green | 6

Grey | 3

The frequency of Red marbles is 2 which means that the red marble came up two times. Similarly, the blue marble came up four times.

The relative frequency of red marble is 2/15 = 0.133 = 13.3%

The relative frequency of green marble is 6/15 = 0.40 = 40%

This means that the green marbles came up 40% of the time.

When relative frequency distributions is preferred?

The relative frequency distributions would be more preferable to use when we want to measure the weight of a particular event or also when we want to compare different categories of data within a table. Moreover, relative frequency is often used for the probability calculations.

PLLLLZ HELLLLLLLLLLLPPPPPPP... i struggle so harddd...

Kazeer [188]

The answer is 6 schools.

In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.

The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.

To make an equation we need to set 100% = 24 and solve for 25% :
$\frac{25}{100} = \frac{x}{24}$
Set the denominators equal:
$\frac{150}{600} = \frac{25x}{600}$
Remove the denominators and solve:
$150 = 25x \\ \\ x = 6$
