Answer:
The degrees of freedom associated with the critical value is 25.
Step-by-step explanation:
The number of values in the final calculation of a statistic that are free to vary is referred to as the degrees of freedom. That is, it is the number of independent ways by which a dynamic system can move, without disrupting any constraint imposed on it.
The degrees of freedom for the t-distribution is obtained by substituting the values of n1 and n2 in the degrees of freedom formula.
Degrees of freedom, df = n1+n2−2
= 15+12−2=27−2=25
Therefore, the degrees of freedom associated with the critical value is 25.
Answer:
Below
Step-by-step explanation:
You can use it if you added a hight.
When you a hight you are creating a right triangle. If not you cannot use directly
Firstly, we can look at our givens,
a = 17
b = 22
c = 30
And we are looking for m∠A
Is the Law of Cosines. Now we can solve for our unknown, m∠A. This will give us
Now we can substitute in our given variables.
Then we can plug this into our calculator which will give us
34.19185257 degrees
Now we just have to round to the nearest tenth
This means that the answer is 34.2 degrees
Hey i don’t wanna do math right now but there’s a link that i could post in the comments if you want it
Answer:
The apricots are $2.24 less expensive per pound.
Step-by-step explanation:
To find the price per pound of each product divide the price Dorian by the number of pounds Dorian bought:
Almonds: 21.98 ÷ 2 = 10.99
Almonds cost $10.99 per pound.
Apricots: 26.25 ÷ 3 = 8.75
Apricots cost $8.75 per pound.
The apricots are less expensive per pound. To find how much less expensive they are compared to the almonds, subtract the cost of the apricots per pound from the cost of the almonds per pound:
10.99 - 8.75 = 2.24
The apricots cost $2.24 less per pound than the almonds do.
