Answer:
units.
Therefore, Option C is correct.
Step-by-step explanation:
We have given a pentagon ABCDE
We need to calculate its length
That means we have to find the distance of AD
So, coordinates of A(1,6) and D(4,-2)
Using distance formula:
Here,
On substituting the values we will get:
On simplification:
.
Hence, the length of AD is units.
Therefore, Option C is correct.
Answer:
<h2>x > -5</h2>
Step-by-step explanation:
-5(x + 7) < -10 <em>use the distributive property </em><em>a(b + c) = ab + ac</em>
(-5)(x) + (-5)(7) < -10
-5x - 35 < -10 <em>add 35 to both sides</em>
-5x < 25 <em>change the signs</em>
5x > - 25 <em>divide both sides by 5</em>
x > -5
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.
Answer:
It doesn't exist
Step-by-step explanation:
The graph must follow the handshake lemma: the sum of odd vertex degrees must be an even number: 1+3+5=9
