For the 3 days he ran a total of : 3 * 900 = 2700 meters.
1000 meters = 1 kilometers
2700 meters = 2700 / 1000 = 2.7 kilometers.
Between last week and this week, Bill ran a total of 6 kilometers.
How far he ran this week = 6 - 2.7 = 3.3 kilometers.
Option C.
Answer:
Resistivity
Step-by-step explanation:
Resistivity : It is a fundamental property of a material that measures how strongly a particular material opposes the flow of electric current. It is also known as specific resistance.
- A low resistivity indicates a material that easily allows the flow of electric current.
- Resistivity is commonly represented by the Greek letter ρ (rho) or abbreviated with a a capital letter K. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).
Hence, the correct answer for the blank is Resistivity.
Answer:
A. Simple Random Sampling
B. Cluster Sampling
C. Convenience Sampling
D. Systematic Sampling
E. Stratified Sampling
Step-by-step explanation:
Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
If the population is divided into a different group called cluster and clusters are selected as a sample then it is Cluster Sampling.
In Convenience sampling, observers collect the sample as his\her convenience.
In Systematic Sampling sample is chosen by some criteria like he\she is taken every 10th unit as a sample from the population.
In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
30 over 4 = 15·2 over 2·2 = 15 over 2 = 1 + 7·2 over 2 = 7 1 over 2
Whole number =7
Fraction = 1 over 2
Hope this helps
Yah I can’t see it either
