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.
A triangle with 2 congruent sides is an <u>ISOSCELES</u> triangle.

FYI: A triangle with 3 congruent sides is an equilateral triangle.
Answer: 46 jumping jacks per minute
Step-by-step explanation: Divide the total number of jumping jacks (184) by the time (4 minutes). Since she is going at a constant rate, this would be equal to 46 jumping jacks per minute. On a coordinate plane, this would be a linear function.
Answer:
3 + 8 times 3 +27 times 3 + 64 times 3+ 125 times 3 + 216 times 3+ 343 times 3
2352 cubic units^3
Step-by-step explanation:
It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red
