Answer:

The value of a and b is given. All u hv to do is just place the values in the places of a and b. The value of a= 3.1 and b= 7.3.

5i) a+b

     3.1+7.3

     =10.4

ii) b-a

   7.3-3.1

    =4.2

5 and 6 are both similar. Just place the numbers instead of the letters

6i) x+y

    5+7

    =12

ii) y-x

   7-5

   =2

iii) x/y

Answer:

Oregon:

Median: 467.5

Mean: 451.33

Standard Deviation: 113.6

Washington:

median: 380

Mean: 396.6

Standard deviation: 56.3

Step-by-step explanation:

To calculate the median, we need to organize the price and select the value that is in the middle position.

To calculate the mean, we need to sum all the values and divide them by the number of values

To calculate the standard deviation, we need to square the distances between every price and the mean, sum it all and divide them by the number of values less 1 and finally calculate the square root.

So, for Oregon, the organized values are:

$295, $345, $460, $475, $538, $595

The median is a value between $460 and $475. it is calculated as:

\frac{460+475}{2}=467.5

The mean is:

\frac{295+475+345+595+538+460}{6}=451.33

The standard deviation is:

\sqrt{\frac{(295-451.3)^2+(475-451.3)^2+(345-451.3)^2+(595-451.3)^2+(538-451.3)^2+(460-451.3)^2}{6-1}}=113.6

At the same way, we can calculate the median, mean, and standard deviation for Washington and get:

median: 380

Mean: 396.6

Standard deviation: 56.3

Ten times the sum of half a number and 6 is 9
xxMikexx [17]
To formulate an equation to represent this, you must simply break apart each section and understand it. The equation is

10(1/2x+6)=9

We can get the "10" because it says "10 times the."
The "1/2x" because it says "half a number"
You will find the "+6" because it said "the sum of half a number and 6"
Is will almost always mean equals, as with this case. Therefore, because it says "is 9" we know it equals 9.
