Answer: 7600
Step-by-step explanation:
8883 when rounded to the nearest hundred is 8900
1277, on the other hand when rounded to the nearest hundred is 1300
Hence, the difference between the rounded values is stated as 8900 - 1300
(8900 - 1300) = 7600
Thus, 7600 is the answer
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is E = 0.03
The sample proportion is 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20)
=> ![n = [\frac{1.96}{0.03} ]^2 *0.12 (1 - 0.12 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.96%7D%7B0.03%7D%20%5D%5E2%20%2A0.12%20%281%20-%200.12%20%29%20)
=>
3 3/5 & 18/5 are both equivalent
Step-by-step explanation:
3 3/5 = 18/5
<u>Write the mixed number as an improper fraction</u>
Step 1: Multiply the denominator by the whole number
5 × 3 = 15
Step 2: Add the answer from Step 1 to the numerator
15 + 3 = 18
Step 3: Write answer from Step 2 over the denominator
18/5
Therefore, 3 3/5 is equivalent to 18/5
You can put it into the form:
Mary = 3x
Seth = X
If we know that Mary is three times older than Seth, we can set this up into an equation.
3x + x = 76
Now, we can simplify on the left side by adding the Xs together.
4x = 76
X = 19
Therefore, Seth is 19 years old and Mary is 57 years old.
