Basically degrees of freedom are related to sample size (n-1). If the df increases, it also stands that the sample size is increasing; the graph of the t-distribution will have skinnier tails, pushing the critical value towards the mean.
If solving for x you will first need to combine like terms. Then after getting the amount of numbers and amount of x numbers you will divide the x number from both. After doing that you would get X=-10
The answer to this question is x^(rt + s) since (x^r)^t becomes x^(rt) by the exponent power of a power property. Then multiplying powers of the same base results in the exponents being summed.
Volume is length times width times height so you would take 10656/(24*18.5)=24 inches
Answer:
the first problem is 216cm
Step-by-step explanation:
(first problem) The 8cm is pointless it just give extra unneeded info a little trick my techer taught me is when you dealing with parellelagrms what you should do is see the dotted line well move the shape the is on the left side of the dotted line to the right side of the parrallelagram and now its a rectangle so all you need to do is 9cm x 24cm = 216cm
