Answer:
equation 2 ??????????
Step-by-step explanation:
Answer:
We know that
The costs of repair for each of the four crashes were
$2529, $1889, $2610, $1073
Here we have to compute the mean, median, and mode cost of repair.
Mean = <u>total</u><u> </u><u>cost</u><u> </u>
the no of crashes
Mean = <u>$</u><u>25</u><u>2</u><u>9</u><u> </u><u>+</u><u> </u><u>$</u><u>188</u><u>9</u><u> </u><u>+</u><u>$</u><u>261</u><u>0</u><u> </u><u>+</u><u>$</u><u>107</u><u>3</u><u> </u>
4
Mean = $2025.25
Therefore the mean = 2025.25
Then we have to find median.
Now first we have to arrange the data in ascending order (smallest to highest).
$1073,$1889,$2529,$2610
Add the two middle numbers and then divide by two, to get the average:
$1889+$2529 = $4418
Median = $4418/2 = $2209
Therefore the median = $2209
Here there is no mode cost.
a. Any vector in the span of is a linear combination of the vectors in . The simplest one we could come up with is the addition of the two vectors we know:
b. Since one vector is quadratic while the other is purely linear, there is no choice of such that
because the only way to eliminate the term is to pick , but there's no way to eliminate the remaining constant term.
