Answer:
10+c=3
Step-by-step explanation:
to solve this you would then subtract 10 from both sides, to get c by itself.
3-10= -7
Your answer would be -7 and the equation would be 10+c=3.
Using sampling concepts, the population and the sample are given as follows:
d. population: 6,000 batches of 100 cards sample: every 100th batch.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a <u>group containing elements of a population</u>. A sample has to be representative of the population, that is, it has to involve all segments of the population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So I ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and then:
- The population is: All New York State residents.
- The sample is the 1000 randomly selected New York state residents.
Hence, in the situation described the population is the 6,000 batches of 100 cards, while the sample is every 100th batch, hence option d is correct.

Answer:
see explanation
Step-by-step explanation:
A drop in temperature is indicated by - ( negative symbol )
A drop of 2° followed by a drop of 3° is
- 2 + (- 3) = - 2 - 3 = - 5°
the sign of the sum is - ( negative add a negative is negative )
the total change in temperature is - 5°
the sum of 2 positive integers is positive , that is
+ 2 + (+ 3) = + 2 + 3 = = + 5
Answer:
Addition property of equality
Explanation:
You are adding 7 to both sides
