Is 7/8 or 11/10 closer to 1? how did you decide?

nirvana33 [79]

11/10 is closer to 1.
To solve for this, give them common denominators. Lets make it 80 for this one.
To get 80, you multiply 8 by 10, so you have to do the same to the number on top. This gives you 70/80.
To get 80 for the second fraction, you multiply by 8 and get 88/80.
Now lets take the numbers on top and subtract them from 80.
88 - 80 = 8
80 - 70 = 10
8 is less than 10, and so 11/10 is closer.

Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to o

Roman55 [17]

Answer:

$Range = 11-2=9$

$\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5$

$\sigma^2 =8.25 \approx 8.3$

$\sigma = \sqrt{8.25}= 2.87 \approx 2.9$

Step-by-step explanation:

Assuming this question: "Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data. 2,3,4,5,6,7,8,9,10,11 "

Solution to the problem

The range is defined as $Range = Max -Min$ and if we replace we got:

$Range = 11-2=9$

Now we can calculate the population mean with this formula:

$\mu =\frac{\sum_{i=1}^n X_i}{N}$

And if we replace we got:

$\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5$

The population variance is given by:

$\sigma^2 = \frac{\sum_{i=1}^n (X_i -\mu)^2}{N}$

And after replace we got: $\sigma^2 =8.25 \approx 8.3$

And the population standard deviation would be just the square root of the variance and we got:

$\sigma = \sqrt{8.25}= 2.87 \approx 2.9$

If 0 = 0 in a systems of equations is it a no solution

elena-s [515]

Answer:

False

Step-by-step explanation:

It is infinitely many solutions

If the equations are not equal, that's when there are no solutions

Infinitely many solutions means that the 2 lines are scalar multiples of each other. They are basically over lapping lines, one of the line just has larger coefficients

EX: x + y = 2

2x + 2x = 4

*These two lines are just scalar multiples of each other. The second equation is just the first equation multiplied by 2. They are the same line.

So any point (x, y) that is on one line is also on the other (these are solutions to the system). There are an infinite amount of points on the line that satisfy the system, so there are infinitely many solutions

Solving this using elimination....

-2x - 2y = -4 (multiply the first equation by -2)

2x + 2y = 4

Now add them....

0 = 0
