Maria has a portfolio consisting of 7 shares of stock A (purchased for $70 per share) and 4 shares of stock B (purchased for $10
Vlad [161]

Answer:

Hence, the expected rate of return after 1 year for Mary's portfolio is 0.17751

Step-by-step explanation:

We have,

Purchase 7 shares of stock A  for $70 per share and 4 shares of stock B for $100 per share then The expected rate of return after 1 year for Mary's portfolio.

Weight invested in stock A is W_x=\frac{7\times 70}{7\times 70+4\times 100}

                                               \Rightarrow W_x=\frac{490}{490+400}\\\Rightarrow W_x=\frac{490}{890}\\\Rightarrow W_x=\frac{49}{89}\\\Rightarrow W_x=0.5505

Weight invested in stock B isW_y=\frac{4\times 100}{7\times 70+4\times 100}

                                             \Rightarrow W_y=\frac{400}{490+400} \\\Rightarrow W_y=\frac{400}{890} \\\Rightarrow W_y=\frac{40}{89} \\\Rightarrow W_y=0.4494

The expected value of the rate of return=W_x\times\;\text{expected rates of stock A}+W_y\times\;\text{expected rates of stock B}

=0.5505\times0.02+0.4494\times0.15

=0.01101+0.06741

=0.17751

Zaria is going down to the arcade to play
Nana76 [90]

Answer:

I believe that it would be y=$0,25x+$5

Step-by-step explanation:

The initial cost to get into the arcade is $5 so that would be the y-intercept (b) in a slope equation (y=mx+b). Since each game costs $0,25, then that would be the slope (m) and x would be the number of games she played. y would equal the total amount of money spent. So if she played 10 games, substitute 10 for x and multiply by 0,25 and take the answer and add 5 to get the total amount.
