https://www.mathhomeworkanswers.org/247010/found-a-standard-deviation-equal-to-937-this-can-be-possible?show=247012#a247012
<p style="text-align: justify;">Yes. A standard deviation can be any positive value. If you divide it by the mean you should get a fraction every time. For example, if the mean population of a group of towns was 10,000 people, the mean and standard deviation would imply quite a modest variation: 10,000±937.5. But if you check the SD against the mean and you don’t get a fraction you have made a mistake (for example, you may accidentally have calculated the variance which is the square of the SD).</p>Statistics Answershttps://www.mathhomeworkanswers.org/247010/found-a-standard-deviation-equal-to-937-this-can-be-possible?show=247012#a247012Sat, 21 Oct 2017 13:49:11 +0000please solve this number pattern for me. 4; 3/4; 4; 1/4; 1/12. and find the next two terms

https://www.mathhomeworkanswers.org/246994/what-is-x-if-3-2x-7-4-7-8x-3-6?show=246995#a246995
<p>3.2x - 7.4 = 7.8x + 3.6</p>
<p>So, when I saw this, all you have to do is the opposite of subtraction which is addition. 3.2 + 7.4 = 10.6. Now 7.8x - 3.6. The answer is 4.2 so x = 10.6, 4.6.</p>
<p><span style="text-decoration: underline;"><strong>ANSWER: 10.6, 4.6</strong></span></p>Algebra 1 Answershttps://www.mathhomeworkanswers.org/246994/what-is-x-if-3-2x-7-4-7-8x-3-6?show=246995#a246995Fri, 20 Oct 2017 22:01:43 +0000Answered: What is the correct answer to this equation and how you got the answer 2-2×3+6=
https://www.mathhomeworkanswers.org/246957/what-correct-answer-this-equation-and-how-you-got-the-answer?show=246986#a246986
<p style="text-align: justify;">Remember that multiplication and division take priority over addition and subtraction so must be carried out first. In this case we must do 2×3 first to get 6, then we can do 2-6+6 which is 2 because the -6+6=0.</p>
<p style="text-align: justify;">Notice that the result of multiplying 2 by 3 replaces 2×3 in the sum.</p>Other Math Topicshttps://www.mathhomeworkanswers.org/246957/what-correct-answer-this-equation-and-how-you-got-the-answer?show=246986#a246986Fri, 20 Oct 2017 14:59:02 +0000Answered: How do you make a fraction a decimal?
https://www.mathhomeworkanswers.org/246962/how-do-you-make-a-fraction-a-decimal?show=246985#a246985
<p style="text-align: justify;">You need to divide the denominator into the numerator. You write the numerator followed by a decimal point and then you can do the division. Treat the numerator as if it had no decimal point and keeping adding zeroes onto the end until you’ve completed the division. The decimal point in the numerator tells you by alignment where to put the decimal point in the quotient. The quotient is the fraction converted to decimal.

3/4=3.00/4=0.75.

<br>
5/7=5.00000/7=0.71428... which can be rounded up to 4 decimal places as 0.7143. This is in fact a recurring decimal and it doesn’t matter how many zeroes you keep adding, the division just keeps on with the same pattern of digits. In this case it’s 0.7142857142857...</p>

<p>Rent a ski jet for X hours</p>
<p>Cost of rental is 34.95 + 15.75*(X - 4)</p>
<p>We want cost <= 100, i.e.</p>
<p>34.95 + 15.75*(X - 4) <= 100</p>
<p>15.75*(X - 4) <= 100 - 34.95</p>

https://www.mathhomeworkanswers.org/246893/the-function-defined-determine-prove-that-for-all-integers?show=246909#a246909
<p style="text-align:justify">If n=1 f(1)=2-7+2f(0)=-5+14=9.
<br>
<br>
f(2)=4-7+18=-3+18=15.
<br>
<br>
f(3)=6-7+30=29.
<br>
<br>
f(4)=8-7+58=59.
<br>
<br>
f(5)=10-7+118=121.
<br>
<br>
f(n)=2n-7+2f(n-1)=-7+2(n+f(n-1)). The factor of 2 operates with each successive evaluation of f(n), so 2ⁿ is going to be applied.
<br>
<br>
f(1)=2×1-7+2f(0)=2×1-7+2×7=2+7.
<br>
<br>
Since we are looking for a formula for n≥0, f(0) is the first term in the series. Since f(0)=7, we can expect 7 to be a constant term in the formula, and the remaining part of the formula to contain the factor n.</p>
<p style="text-align:justify">If we look at the series: 7, 9, 15, 29, 59, 121 and take the differences between consecutive pairs we get:</p>
<p style="text-align:justify">2, 6, 14, 30, 62</p>
<p style="text-align:justify">If we take half of these we get:</p>
<p style="text-align:justify">1, 3, 7, 15, 31 which can be represented by 2ⁿ-1. Therefore doubling gives 2(2ⁿ-1). And f(n)-f(n-1)=2(2ⁿ-1), so f(n)=f(n-1)+2(2ⁿ-1). </p>
<p style="text-align:justify">f(n-1)+2(2ⁿ-1)=2n-7+2f(n-1) from which</p>
<p style="text-align:justify">f(n-1)=2(2ⁿ-1)-2n+7, therefore f(n)=2(2ⁿ-1)-2n+7+2(2ⁿ-1)=4(2ⁿ-1)-2n+7.</p>
<p style="text-align:justify">Check formula for n=0 to 5:</p>
<p style="text-align:justify">f(0)=7, f(1)=9, f(2)=15, f(3)=29, f(4)=59, f(5)=121. The formula in the question doesn’t generate the correct series. So <strong>f(n)=4(2ⁿ-1)-2n+7</strong>.
