Answer:
28
Step-by-step explanation:
Degrees of freedom is defined as the number of independent values or quantities which can be assigned to a statistical distribution.
#In a two sample study, the t-statistic degrees of freedom is calculated as
#Where denotes the sample size of the sample.
The t-statistic degrees of freedom is thus 28
Answer:
CosA/CosB =1
CosA = Adjacent side/Hypotenuse
=AC/AB = 3/4.24
Cos B = Adjacent side/Hypotenuse
= BC/AB = 3/4.24
CosA/CosB = (3/4.24)/(3/4.24) = 1
The value of CosA/CosB = 1
Answer:
68
Step-by-step explanation:
First you multiply 8 and 4 to get 32 and that shows you how many campers have agreed to help. Next you have to subtract 32 from 100 to know how many more people you need.
Okay so in order to find your slope you're going to need to label your first set of coordinates! Since you know that -6 is X, you're going to label it X(subscript 1) and since you know that 7 is Y, you're going to label it Y(subscript 1).
You're going to want to do the same thing with the other set of coordinates as well. -6 will be X(subscript 2) and -2 will be Y(subscript 2).
Then you need to set the labeled coordinates up in the following formula:
m=y(subscript 2) - y(subscript 1) / x(subscript 2) - x(subscript 1)
and then solve for your slope!
