When you divide a number by 10^n (i.e. 1 followed by n zeroes), you move the decimal point separator n places to the left (assuming that integers have the decimal separator at the end, as in 2 = 2.0).
So, the first option is to divide 18 by 100. So, we start from 18=18.0 and move the separator two places to the left:
The second option is to divide 8 by 10. So, we start from 8=8.0 and move the separator one place to the left:
The third option is to divide 18 by 10. So, we start from 18=18.0 and move the separator one place to the left:
So this is the correct option.
Answer:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
Step-by-step explanation:
The population is all the adult men who are 40 to 60 years of age and live in the United Stades.
The 1338 are the sample, and the study wants to find the proportion of all these adults who had seen their family doctor. Since 1338 is a large sample size, this proportion can be extended to all the adult men who are 40 to 60 years of age and live in the United Stades.
Answer:
we have:
∆BDE is similar to ∆BAC
so their side are proportional :
BD/BD=BE/BC
2/BD=4/(6+4)
BD=2×10/4
BD=5
again
BE/BC=DE/AC
4/10=5/AC
AC=5×10/4
AC=25/2
Now,
<u>AC</u><u>=</u><u>2</u><u>5</u><u>/</u><u>2</u><u> </u><u>or</u><u> </u><u>1</u><u>2</u><u>.</u><u>5</u><u>.</u>
<u>AD</u><u>=</u><u>BA-BD</u><u>=</u><u>5</u><u>-</u><u>2</u><u>=</u><u>3</u><u>.</u>
<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
4b - 10 = 2 (2b - 5)
4b - 10 = 4b - 10
4b - 4b = -10 + 10
b = 0
Hence, b has only one answer so,
we can say that this equation has only one solution.
Both step 1 and step 2 were correct with the process of moving the value of x into the place of x and continuing to solve. However, step 3 is incorrect because when it is a negative value being subtracted by another negative value, it remains a negative. So the answer is -14 instead of 14.
