The diagram shows the length and width of a cell phone, and the length of a larger
version of the same brand of cell phone.
2.6 in.
5.4 in.
6.21 in.
The lengths and widths of the two cell phones are proportional. What is the width,
in inches, of the larger version of the cell phone?

Answers

Answer 1

Answer:

The width of the bigger phone is 2.99 in

Explanation:

Given

[tex]W_1 = 2.6in[/tex]

[tex]L_1 = 5.4in[/tex]

[tex]L_2 = 6.21in[/tex]

See attachment for the measure of cell phones

Required

Determine the width of the bigger version (L2)

To do this, we make use of the following equivalent ratios.

[tex]L_1 : W_1 = L_2 : W_2[/tex]

This gives:

[tex]5.4\ in : 2.6\ in : 6.21\ in : W_2[/tex]

Express as fractions

[tex]\frac{5.4\ in}{2.6\ in} = \frac{6.21\ in}{W_2}[/tex]

[tex]\frac{5.4}{2.6} = \frac{6.21\ in}{W_2}[/tex]

Make W2 the subject

[tex]W_2 = \frac{6.21 * 2.6\ in}{5.4}[/tex]

[tex]W_2 = \frac{16.146\ in}{5.4}[/tex]

[tex]W_2 = 2.99\ in[/tex]

The payoff matrix that follows shows the payoff each person will earn as a function of both of their choices. For example, the lower-right cell shows that if Manuel chooses Right and Poornima chooses Right, Manuel will receive a payoff of 3 and Poornima will receive a payoff of 7. Poornima Left RightManuel Left 4,4 3,3 Right 5,4 4,3The only dominant strategy in this game is for (Manuel/Poornima) to choose (left/right).The outcome reflecting the unique Nash equilibrium in this game is as follows: Manuel chooses (left/right) and Poornima chooses (left/right).
