The formula for the circumference of a circle is 2•Pi•R (radius)or Pi•D (diameter).
Since we have the Radius, 5, let's use the 2•Pi•R path.
Pi is defaultly used as 3.14
Plug in 5 for R.
2 • 3.14 • 5
2• 5 = 10
10 • 3.14 = 31.4
The circumference of your circle is 31.4 CM.
Answer: 31cm

Answer:
a. Describing a sample with mean and standard deviation.
Step-by-step explanation:
Statistics can be categorized into descriptive and inferential statistics.
descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.
- Measures of Central Tendency ( Mean, Median, and Mode)
- Measures of Frequency (Count, Percent, Frequency)
- Measures of Position (Percentile Ranks, Quartile Ranks.)
- Measures of Dispersion ( Range, Standard Deviation)
Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.
options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.
Step-by-step explanation:
there and if I'm pretty sure y equals 2
