P(5,2) = n! /(n-r)!
n = 5, r = 2:
= (5 x 4 x 3 x 2 x 1 ) / 3 x 2 x 1
Cancel out common factors:
= 5 x 4 = 20
The answer is 20.
Answer:
1000 or more
Step-by-step explanation:
because the motor is is good shape
if you multiply 6 and 3354 the answer is equal to 20124
The best way to work this to add the two numbers of the ratio together (8+5), giving you 13. You should then divide the total number of cards (78), by this, giving you 6. This means that each part of the ratio is worth 6. The first ratio is 8, meaning that you will have 6x8 baseball cards. There will be 48 baseball cards. The second ratio is 5, meaning that you will have 6x5 football cards. There will be 30 football cards.
In the box, there are 48 baseball cards
The researcher should use regression analysis, as a statistical tool, because the researcher is working with two variables measured.
<h3>Regression analysis</h3>
Regression analysis is the most widely used statistical tool that can be used to find out the relation between a set of variables. Thus, from its results, it is possible to analyze the trend or make predictions. In a regression analysis, it is considered the relationships between two or more variables and it is very similar to correlation.
Like the researcher is working with two variables measured at the interval level. The researcher should use regression analysis.
