Answer:

Online customers buy an average of five packs compared with walk-in customers, who buy an average of two packs.

Step-by-step explanation:

0(2) + 0(3) + 10(4) + 40(5) + 50(6)

540

On average, 540/100 = 5.4

60(2) + 30(3) + 10(4) + 0(5) + 0(6)

= 250

On average, 250/100 = 2.5

julia-pushkina [17]

Answer:

  • a. incorrect
  • A. equal to
  • 59.20 ÷ 10 = 5.920

Step-by-step explanation:

What Douglas doesn't seem to realize is that it is not the act of removing the trailing zero that gives division by 10. It is the act of moving the decimal point left one place that divides the number by 10.

Kris and Julia play the card game. Together they scored 36 points and one game. Kris scored two times as many points as Julio. H
alexira [117]
Kris has 24 points and Julio has 12 points.  I kept on trying different numbers until I got 12. Next, I multiplied 12 by 2 and it equaled 24. Finally, I added 24+12 which equaled 36. This is how I knew that Julio has 12 points and Kris has 24 points.

Answer:

\theta=cos^{-1}(\frac{2}{3})

Step-by-step explanation:

We are given that measurements of three points on the ground gave coordinates of (0,0,0),(1,2,0) and (0,2,1)

We have to find the angle by which the tower now deviate from the vertical

We find cross product of <1,2,0> and <0,2,1>

\times =\begin{vmatrix}i&j&k\\1&2&0\\0&2&1\end{vmatrix}

\times =2\hat{i}-\hat{j}+2\hat{k}

Now, we are finding the angle between  \timesand vertical vector <0,0,1>

Angle between two vectors formula

cos\theta=\frac{a.b}{\mid a\mid\cdot\mid b\mid }

Now, using this formula

cos\theta=\frac{2}{1\cdot 3}=\frac{2}{3}

\theta=cos^{-1}(\frac{2}{3})

Hence, the tower deviate from the vertical by the angle \theta=cos^{-1}(\frac{2}{3})
