13.8% = 0.138 in decimal form.
Percent means 'per 100'. So, 13.8% means 13.8 per 100 or simply 13.8/100.
If you divide 13.8 by 100, you'll get 0.138 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (13.8) by 100, and remove the "%" sign.
Answer:
M=3/4J or J=4/3M
Step-by-step explanation:
3:4, 9:12, and 15:20 are ratios that are equal to each other.
If you multiply 3:4 by 3 you get 9:12 and if you multiply it by 4 you get 15:20
another way to check is to plug the numbers in.
3 is 3/4 of 4
9 is 3/4 of 12
15 is 3/4 of 20
so the equation is true

We have given,
The population variances are not known and cannot be assumed equal.
The test statistic for the test is
Where,
= sample meaan of population 1
= sample mean of population 2
= sample size of population 1
= sample size of population 2
Therefore, this is the test
