Place the following in increasing order: 3/5 70% 0.8 11/20 65% 0.09. How would you explain your process to someone else?

zepelin [54]

I converted all to decimal

x%=x/100
so

3/5=6/10=0.60
70%=70/100=7/10=0.70
0.8=0.80
11/20=5.5/10=0.55
65%=65/100=6.5/10=0.65
0.09=0.09

so increasing
smallest to largest
0.09, 0.55, 0.60, 0.65, 0.70, 0.80
or
0.09, 11/20, 3/5, 65%, 70%, 0.8

Answer:

Option B

Step-by-step explanation:

First identify which options are a match for the hyperbola with a foci of (- 12, 6) and ( 6, 6 ). If there is only one, we can claim that that is the solution. Otherwise we would have to take the vertices into account,

The first option can be eliminated as it is present with a decimal in the denominator, indicating that the foci should also be a decimal. However, the foci of this option should be valuable to us -

$\left(h+c,\:k\right),\:\left(h-c,\:k\right),\\\left(-3+c,\:6\right),\:\left(-3-c,\:6\right),\\c = ( About ) 3.6,\\\\Foci = \left(0.55808 ,\:6\right),\:\left(-6.55808,\:6\right)$

The second option squares the denominators of the first option, so the foci should be the following -

$Foci = ( - 12, 6 ), ( 6, 6 )$

Which is the given! The rest of the options are similar to this second option, but are altered, thus don't have the same foci,

<u><em>Solution = Option B</em></u>

Answer:

Sample mean for solution 1: 19.27; sample mean for solution 2: 10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32
