So 6 in pond
some on grass
# in pond+# in grass=14
6 in pond
subsitute 6 for pond
6+# in greass=14
subtract 6 from both sides
6-6+# in grass=14-6
0+# in grass=8
# in grass=8
there are 8 ducks in grass
so you would draw a circle for the pond and put 6 circles in there to represent the ducks, then , outside of that big circle, draw 8 circles to represent the 8 ducks on the grass (maybe label the big circle as pond and outside as grass)
Rounding numbers means you change the number to a closer, easier number. For example if you want to round 56 to the nearest tenth, it would round to 60.
Estimating numbers is when you guess numbers. For example, if you want to estimate the measure used to measure a bed, i would estimate feet.
I hope this helped:))
Answer:
<u>567</u> people were surveyed.
Step-by-step explanation:
Given:
A survey claims that the percent of an entire population that agrees with redeveloping the city park is likely between 49.1% and 57.5%.
Now, to find total people who were surveyed.
<em>According to survey percent of population agrees between = 49.1% to 57.5%.</em>
So, we need to find the error of margin:
Let the number of people surveyed be 
Now, to get the number of people surveyed:
<em>By cross multiplying we get:</em>
<em />
<em />
<em />
<em />
<em>Using square root on both sides we get:</em>
<u>Approximately:</u>
<u />
<u />
Therefore, 567 people were surveyed.
I think it's 11 (or 11.1) because it gave you 500 as the total and it increases by 45 every year (45x).
45x=500
45x÷45=x
500÷45=11 (rounded instead of 11.11111.....)
