Option C

<u>SOLUTION:</u>

We need to find the value of B - CF

First find the value CF:

CF=\left[\begin{array}{ccc}12&0&1.5\\1&-6&7\\\end{array}\right]  \left[\begin{array}{ccc}-2&0\\0&8\\2&1\end{array}\right]

CF=\left[\begin{array}{ccc}12(-2)+0 *0+1.5*2&12*0+0.8+1.5*1\\1*(-2)+(-6)*0+7.2&1*0+(-6)*8+7.1\\\end{array}\right]

CF=\left[\begin{array}{ccc}-21&1.5\\12&-41\\\end{array}\right]

Now find value of B - CF:

B-CF=\left[\begin{array}{ccc}2&8\\6&3\\\end{array}\right] -\left[\begin{array}{ccc}-21&1.5\\12&-41\\\end{array}\right]

B-CF=\left[\begin{array}{ccc}23&6.5\\-6&44\\\end{array}\right]

∴ the value of B - CF is \left[\begin{array}{ccc}23&6.5\\-6&44\\\end{array}\right]

What is the median of the data set?<br><br> 50 41 33 35 70 56 53 42 33 62
Firdavs [7]

To find the median of the data set, you must first put the numbers in order

33, 33, 35, 41, 42, 50, 53, 56, 62, 70

Now that we have them in order, find the one that is in the middle. In this case it's an even amount of numbers so there are 2 middle numbers 42 and 50.

What you do when you end up with this situation all you have to do is add the two middle numbers

42 + 50 = 92 then divide the total by 2, which is finding the average of the two numbers.

92 ÷ 2 = 46

46 is the median of the data set.

Hope this helps. :)

Consider the equation 2*e^-6w=95 Solve the equation for w. Express the solution as a logarithm in base-e
pishuonlain [190]

Answer:

log_e \Big (\dfrac{95}{2} \Big )= {-6w}

Step-by-step explanation:

From the given information:

We need to find the value of w

2*e^{-6w}= 95

Divide both sutiet sl???ides. VVVVV

e^{-6w}= \dfrac{95}{2}

Taking the logarithim in base in e for both sides:

log_e \Big (\dfrac{95}{2} \Big )= {-6w}
