Answer:
White Kg, : 1.2
Green Kg, : 2
Black kg, : 2.8
Step-by-step explanation:
Ratio of amount of white, green and black tea is 3 : 5 : 7
This means, out of every 3+5+7= 15 parts, 3 parts are white tea, 5 parts are green tea and 7 parts are black tea.
We have to find, how many kilograms of each tea are needed to make a total of 6 kg of the mixture keeping the above ratio.
The formula to this is:
For example, for white tea, the concerned part in the ratio is 3, for green its 5 and for black tea its 7. Total parts remain 15 in three cases. The total amount is also fixed which is 6kg.
Using these values, we get<u>:</u>
Kilograms of White tea = kg
Kilograms of Green tea = kg
Kilograms of Black tea = kg
Answer:
19.26%
Step-by-step explanation:
Given the original selling price of DVD player as $179.30 and the new sale price to be $144.77, the the first step in finding the percent markdown is to take the difference between the original selling price and the sale price to give $179.30 - $144.77 = $34.53
Percent markdown = original selling price- new sale price/original selling price × 100%
Percent markdown = $34.53/$179.30 × 100%
% markdown = 19.26%
Answer:
The problem is an example of d.) multinomial population
Step-by-step explanation:
A multinomial distribution is type of probability distribution that describes the distribution of more than two variables.
The properties of a multinomial distribution are:
- There are <em>n</em> independent and repeated trials.
- Each trial has two outcomes: Success of Failure.
- Each outcome of a trial is same.
In the case provided the variables are:
<em>X</em> = number of students in Business college
<em>Y</em> = number of students in Arts college
<em>Z</em> = number of students in Arts college.
The researcher wants to know if the proportion of the variables <em>X</em>, <em>Y</em> and <em>Z</em> has changed or not.
This is an example of multinomial distribution and the population is a multinomial population.
