You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.
To convert Hectometers to kilometers you divide by 10:
8.7 / 10 = 0.87 kilometer
8.7 hectometers = 87 kilometers = FALSE.
Multiply centigrams by 10 to get milligrams:
4.02 x 10 = 40.2
4.02 centigrams = 40.2 milligrams = TRUE.
Milliliter to liter:
Divide milliliters by 1000:
0.001 / 1000 = 0.000001
0.001 milliliter = 0.1 liter = FALSE.
Meter to kilometer:
Divide meters by 1000:
0.004 / 1000 = 0.000004
0.004 meter = 0.000004 kilometer = TRUE.
Answer:
Parallel.
Step-by-step explanation:
Parallel lines have equal slopes
(In y = mx + b), m = slope, and the slopes are equal.
33.3..........................................
F(x)=2x-4 because the y-int is -4 and it’s going up two each time and over one so 2/1 or just 2x
