Ve thirds Conversion a mixed number 1 5/ 6 to a improper fraction: 1 5/6 = 1 5/ 6 = 1 · 6 + 5/ 6 = 6 + 5/ 6 = 11/ 6 To find a new numerator: a) Multiply the whole number 1 by the denominator 6. Whole number 1 equally 1 * 6/ 6 = 6/ 6 b) Add the answer from previous step 6 to the numerator 5. New numerator is 6 + 5 = 11 c) Write a previous answer (new numerator 11) over the denominator 6. One and five sixths is eleven sixths Divide: 5/ 3 : 11/ 6 = 5/ 3 · 6/ 11 = 5 · 6/ 3 · 11 = 30/ 33 = 3 · 10 / 3 · 11 = 10/ 11 Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 11/ 6 is 6/ 11 ) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 3 gives 10/ 11 . In other words - five thirds divided by eleven sixths = ten elevenths.

The quotient of 4 and 1/5 will be greater than 4.

bixtya [17]

First, we will need to compute the quotient of 4 and 1/5
When we divide a number by a fraction, we convert the division to multiplication and then flip this fraction.
Therefore, in the given:
4 / (1/5) we will convert the division into multiplication and flip the 1/5 to 5
This will result is the following:
4 / (1/5) = 4*5 = 20

Comparing this quotient to 4, we will find that the quotient is greater than 4

Therefore, the given statement is: True

A web site charges $0.99 to download a game and a 12.49 membership fee.write an expression that gives the total cost in dollars

icang [17]

Hello!

To write this equation we will use c to represent the total cost, and g to represent however many games you download.

c=12.49+0.99g

The constant rate is 12.49, that will never increase or change in our equation.

Depending on how many games you download, that will be the rate that affects our total cost.

If you only purchase one game, you only spend $13.48. Where as if you buy 10 games, you spend $22.39.

ziro4ka [17]

Answer:

a) $\frac{(8)(30.23)^2}{20.09} \leq \sigma^2 \leq \frac{(8)(30.23)^2}{1.65}$

$363.90 \leq \sigma^2 \leq 4430.80$

Now we just take square root on both sides of the interval and we got:

$19.08 \leq \sigma \leq 66.56$

b) For this case we are 98% confidence that the true deviation for the population of interest is between 19.08 and 66.56

Step-by-step explanation:

423.6, 487.3, 453.2, 402.9, 483.0, 477.7, 442.3, 418.4, 459.0

Part a

The confidence interval for the population variance is given by the following formula:

$\frac{(n-1)s^2}{\chi^2_{\alpha/2}} \leq \sigma^2 \leq \frac{(n-1)s^2}{\chi^2_{1-\alpha/2}}$

On this case we need to find the sample standard deviation with the following formula:

$s=sqrt{\frac{\sum_{i=1}^8 (x_i -\bar x)^2}{n-1}}
And in order to find the sample mean we just need to use this formula:
[tex]\bar x =\frac{\sum_{i=1}^n x_i}{n}$
