Your question is not complete, however, I have provided answers to it by suggesting that the question goes like this;
Twelve different video games showing drug use were observed. The duration times of drug use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 85sec, what does df denote, and what is its value
Answer:
df denote degree of freedom.
degree of freedom df is 11.
Step-by-step explanation:
what does df denote?
df denote degree of freedom
To find it value,
we have twelve different video games showing drug use, then, it means that the sample size "n" is 12
the degree of freedom is 1 < n ( i.e, one less than sample size)
df = n -1 = 12 -1 = 11
So, degree of freedom df is 11.
Note; use your sample size to solve the question as I don't know the exact value you were given. Thanks.

Step-by-step explanation:
4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile

Answer:
We are observing the galactic center as it was 27,000 years ago
Step-by-step explanation:
The Galactic Center, or Galactic Centre, is the rotational center of the Milky Way. It is 8,122 ± 31 parsecs (26,490 ± 100 ly) away from Earth in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius where the Milky Way appears brightest. It coincides with the compact radio source Sagittarius A*
